Factors ,symptoms ,treatment for macular degeneration

What are risk factors for macular degeneration?

The greatest risk factor is age. Although AMD may occur during middle age, studies show that people over age 60 are clearly at greater risk than other age groups. Middle-aged people have about a 2% risk of getting AMD while people over age 75 have a nearly 30% risk.
Other risk factors include smoking, obesity, white race, female gender, a family history of macular degeneration, a diet low in fruit and vegetables, high blood pressure, and elevated blood cholesterol.

What are macular degeneration symptoms?

Neither dry nor wet AMD cause any eye pain.
The most common early symptom in dry AMD is blurred vision. As fewer cells in the macula are able to function, people will see details less clearly in front of them, such as faces or words in a book. Often this blurred vision will go away in brighter light. If the loss of these light-sensing cells becomes great, people may see a small black or gray blind spot in the middle of their field of vision.
Dry macular degeneration symptoms usually develop gradually and do not include total blindness. However, the symptoms may worsen the quality of life by making reading, driving, and facial recognition difficult Other symptoms may include decreased night vision, a decrease in the intensity or brightness of colors, increase in the haziness of overall vision.
Dry macular degeneration may affect one eye or both eyes. If only one eye is affected, symptoms may not be noticed because the unaffected eye has no visual symptoms.
All of the above symptoms may also be noticed in the wet form of AMD. In addition, the most common symptom in wet macular degeneration is straight lines appearing crooked or wavy. This results when fluid from the leaking blood vessels gathers within and lifts the macula, distorting vision. Larger areas of gray or black in the central area of vision may also occur. The central vision may decrease over a short period of time.

What are signs of macular degeneration?

In both dry and wet forms of macular degeneration, the ophthalmologist may find decreased visual clarity (acuity) with preservation of peripheral vision and changes in the central retina visible with the ophthalmoscope.

How is macular degeneration diagnosed?

Your ophthalmologist may suspect the diagnosis of AMD if you are over age 60 and have had recent changes in your central vision. To look for signs of the disease, he or she will use eyedrops to dilate, or enlarge, your pupils. Dilating the pupils allows your ophthalmologist to view the back of the eye better.
Early AMD is often diagnosed during a comprehensive eye exam in patients without significant symptoms. This eye exam includes having drops placed in your eyes to enlarge, or dilate, the pupils. Your ophthalmologist will carefully examine the central portion of the retina to determine the presence or absence of AMD using various illuminating and magnifying devices.
During the eye exam, you may be asked to look at a checkerboard pattern called an Amsler grid. When looking at an Amsler grid with one eye, patients with AMD may notice that the straight lines of the checkerboard appear wavy or are missing.
Other diagnostic tests that your ophthalmologist may perform include retinal photography, fluorescein angiography and optical coherence tomography. All of these can help to differentiate between dry and wet forms of AMD and also document the abnormalities so that progression and response to treatment can be better measured.

What is the treatment for wet macular degeneration?

Wet AMD can be treated with laser surgery, photodynamic therapy, and injections into the eye. None of these treatments is a permanent cure for wet AMD. The disease and loss of vision may progress despite treatment.
Laser surgery is used to destroy the fragile, leaky blood vessels. A high energy beam of light is aimed directly onto the new blood vessels to eradicate them, preventing further loss of vision. However, laser treatment may also destroy some surrounding healthy tissue and some vision. Because of this, only eyes with new vessels away from the exact center of the vision can be treated. This represents only a small proportion of patients with AMD. Laser surgery is only effective in halting or slowing visual loss if the leaky blood vessels have developed away from the fovea, the central part of the macula. Even in treated cases, the risk of new blood vessels recurring after treatment is significant and further or other treatment may be necessary.
Photodynamic therapy uses a drug called verteporfin (Visudyne) being injected into a vein of the arm. A light is then directed into the eye to activate the drug adhering to the blood vessels in the eye. The activated drug destroys the new blood vessels and leads to a slower rate of vision decline. Photodynamic therapy may slow the rate of vision loss. It does not stop vision loss or restore vision in eyes already damaged by advanced AMD. Treatment results often are temporary. Retreatment may be necessary.
Within the last seven years, injections into the eye with drugs specifically developed to stop the growth of new blood vessels have revolutionized the treatment of wet macular degeneration. We have learned that a specific chemical called vascular endothelial growth factor (VEGF) is necessary for the new blood vessels to grow under the retina. Drugs that counter VEGF (anti-VEGF pharmacotherapy) can be injected into the eye to arrest development of new blood vessels and sometimes cause them to regress. These drugs are injected in the ophthalmologist's office and may need to be given as frequently as monthly. Careful observation of the eye on a monthly basis to determine the drug effect is necessary. With this treatment, visual loss can often be halted or slowed and some patients will even experience some improvement of vision. Newer drugs currently under review may need to be given less frequently.
In patients with far advanced macular degeneration on both eyes, surgery to implant a telescopic lens in one eye is an option. The telescope implant, which surgically replaces the eye's natural lens, magnifies images while reducing the field of vision (peripheral vision). The telescopic lens implant may improve both distance and close-up central vision.

What is the treatment for dry macular degeneration?

There is currently no treatment available to reverse dry macular degeneration. However, dry macular degeneration is usually slowly progressive and most patients with this condition are able to live relatively normal, productive lives. Often one eye is affected more than the other.
Once dry AMD reaches the advanced stage, no form of treatment can prevent further vision loss. However, treatment can delay and possibly prevent intermediate AMD from progressing to the advanced stage of severe vision loss. The National Eye Institute's Age-Related Eye Disease Study (AREDS) found that taking a specific high-dose formulation of antioxidants and zinc significantly reduces the risk of advanced AMD and it's associated vision loss. Slowing AMD's progression from the intermediate stage to the advanced stage is helpful in reducing the progression of visual loss in many people.
In this study, researchers used an antioxidant formulation that included vitamin C, vitamin E, beta carotene (or vitamin A), and zinc. For people with early-stage dry macular degeneration, there is no evidence that these vitamins provide a benefit. It is recommended that people with intermediate-stage dry AMD in one or both eyes or advanced stage AMD (dry or wet) in one eye, but not the other eye, take the AREDS formulation. Patients with increased risk of lung cancer should not take beta carotene. Studies involving other supplements such as lutein and bilberry are currently being performed.
The progression of dry age-related macular degeneration can also be slowed through lifestyle changes. These include changing the diet to include more fruits and vegetable, choosing healthy unsaturated fats, such as olive oil, over unhealthy saturated fats, such as butter, eating whole grains rather than refined grains and adding fish high in omega-3 fatty acids.

What are complications of macular degeneration?

Progression to wet macular degeneration is the main complication of dry age-related macular degeneration. At any time, dry macular degeneration can progress to the more severe form of the disease called wet macular degeneration, which may cause rapid vision loss. There's no accurate way to predict who will eventually develop wet macular degeneration.
Other eye diseases such as cataracts, glaucoma, retinal detachment, or dry eyes are not complications of macular degeneration. Patients with macular degeneration can, however, develop these or other eye diseases.

What is the prognosis for macular degeneration?

Macular degeneration in its advanced form can cause loss of all central vision in both eyes. In the absence of other eye diseases, peripheral vision is maintained. Therefore, patients with advanced macular degeneration are, in most cases, able to see enough to get around in familiar situations.
The use of magnifying devices can often improve vision in macular degeneration to allow for reading or watching of television.

Macular Degeneration

Macular degeneration facts

  • The macula is in the center of the retina, the light-sensitive layer of tissue at the back of the eye. The macula is responsible for central vision (straight-ahead vision). Degeneration of the macula occurs most often after the age of 60 years and is termed age-related macular generation (AMD).
  • AMD is a painless condition.
  • There are two types of AMD: dry AMD and wet AMD.
  • Smoking, high blood pressure, obesity, a diet high in unsaturated fats and simple carbohydrates and lack of exercise all increase the risk of AMD.
  • Early symptoms of dry AMD include slightly blurred vision, the need for more light for reading, and difficulty recognizing faces until very close to the person. A symptom of more advanced dry AMD is the presence of a blurred spot in the center of vision. An early symptom of wet AMD is the wavy appearance of straight lines.
  • Dry AMD cannot be treated at present, but progression can be slowed through a healthy lifestyle and, in certain cases, through anti-oxidant vitamins. Injections into the eye of anti-angiogenic agents are successfully used in arresting or slowing wet AMD. Because of new therapies for the wet form of AMD, early diagnosis of wet AMD is particularly critical. 

What is macular degeneration?

Macular degeneration is a common, painless eye condition in which the central portion of the retina deteriorates and does not function adequately.

What is the retina?

The retina is the light sensitive tissue located in the back of the eye. It is like the film in a camera, recording the images we see and sending them via the optic nerve from the eye to the brain. The retina instantly converts light images into electrical impulses through a chemical reaction. The retina then sends these impulses or signal, to the brain, where we interpret what we see, process the visual information, and relate what we see to the rest of our environment.

What is the macula?

The macula is a small portion of the retina located in the central portion of the retina. The macula is responsible for central vision (straight-ahead vision) and provides the ability to see fine detail in your direct line of sight. We use the macula of each eye to have the clear vision that allows us to read, drive a car, and recognize faces or colors. The non-macular areas of the retina provide us with our side vision and best night vision.

What is age-related macular degeneration (AMD)?

Although there are many types of macular degeneration, age-related macular degeneration (AMD or ARMD) is by far the most common type. AMD is a disease associated with aging that gradually destroys sharp central vision that is needed for seeing objects clearly and for common daily tasks such as reading and driving. In some cases, AMD advances so slowly that people notice little change in their vision. In others, the disease progresses faster and may lead to a loss of vision in both eyes. AMD is the leading cause of vision loss in Americans 60 years of age and older. AMD usually affects both eyes, although the clinical appearance and degree of visual loss may vary a great deal between the two eyes.
AMD occurs in two forms. "Wet" age-related macular degeneration is less common but more aggressive in its progression to severe central vision loss. "Dry" age-related macular degeneration is the more common type and is more slowly progressive in causing visual loss..

What is wet age-related macular degeneration?

Wet AMD occurs when abnormal blood vessels grow from the choroid (the layer of blood vessels between the retina and the outer firm coat of the eye called the sclera) under and into the macular portion of the retina. These new blood vessels (known as choroidal neovascularization or CNV) tend to be very fragile and often leak blood and fluid. The blood and fluid raise the macula from its normal place at the back of the eye and interfere with the retina's function and causes the central vision to blur. Under these circumstances, vision loss may be rapid and severe. Some patients, however, do not notice visual changes despite the onset of CNV. Therefore, periodic eye examinations are very important for patients at risk for CNV.
Once CNV has developed in one eye, whether there is a visual loss or not, the other eye is at relatively high risk for the same change.
All wet AMD is described as advanced AMD, whether or not there is serious visual loss. Wet AMD does not have not have stages like dry AMD. The wet form generally leads to significantly more vision loss than the dry form.
All people who have the dry form of AMD are at risk for development of the wet form. All people who have the wet form had the dry form first. The dry form can advance and cause vision loss without turning into the wet form. The dry form also suddenly can turn into the wet form. Currently, there is no certain way to predict if or when the dry form will turn into the wet form.

What are retinal drusen?

Retinal drusen are yellow deposits under the retina. They often are found in people over 60 years of age. Your eye-care professional can detect drusen during a comprehensive dilated eye exam.
Drusen alone do not usually cause vision loss. In fact, scientists are unclear about the connection between drusen and AMD. It is not clear if an increase in the size or number of drusen raises a person's risk of developing either advanced dry AMD or wet AMD. These changes can cause serious vision loss.

What is dry age-related macular degeneration?

In dry AMD, the light sensitive cells in the macula slowly break down. With less of the macula functioning, central vision diminishes. Dry AMD often occurs in just one eye at first. Later, the other eye can be affected. The cause of dry AMD is unknown.
Dry AMD has three stages, early, intermediate, or advanced, all of which may occur in one or both eyes. People with early AMD have either several small drusen or a few medium-sized drusen. At this stage, there are no symptoms and no vision loss.
People with intermediate AMD have either many medium-sized drusen or one or more large drusen. Some people see a blurred spot in the center of their vision. More light may be needed for reading and other tasks.
In addition to drusen, people with advanced dry AMD have a breakdown of light-sensitive cells and supporting tissue in the central retinal area. This breakdown can cause a blurred spot in the center of your vision. Over time, the blurred spot may get bigger and darker, taking more of your central vision. You may have difficulty reading or recognizing faces until they are very close to you.
The dry form is much more common than the wet form. In dry AMD, there is no CNV (abnormal new blood vessel formation under the retina) and no fluid or blood leakage into the retina (retinal swelling or bleeding). More than 85% of all people with intermediate and advanced AMD combined have the dry form. However, if only advanced AMD is considered, about two-thirds of patients have the wet form.
Dry AMD can advance and cause vision loss without turning into wet AMD. Dry AMD can also rapidly transform into the wet form by the growth of new blood vessels.

What causes macular degeneration?

We do not know the precise cause for the development of ARMD. However, we do know that there are certain risk factors for the development of age-related macular degeneration.

Treatment for childhood obesity

What are risk factors for childhood obesity?

There are several substantial risk factors for the development of pediatric obesity.
  1. Genetics: While several genetic syndromes are associated with obese stature (for example, Prader-Willi syndrome), genetics are not responsible for the obesity epidemic currently taking place. There has been no change in the gene pool over the last 30 years. Most recent studies indicate that if one parent is obese the likelihood of having an obese child is three times higher than otherwise. If both parents are obese, the likelihood is 10 times higher.
  2. Social: Limited school athletic activities coupled with excessive time-utilizing social networks, TV, and computer games are a prime reason for pediatric obesity. Watching TV while eating a meal as well as the excessive consumption of takeout/fast food are also both risk factors for both pediatric and adult obesity. Recent studies indicate that only 20% of children experience more than two episodes of vigorous play per week, and 25% of these children watched more than four hours of TV per day. This does not include additional time engaging in computer games, texting, or talking on the phone with friends. Having a TV in the bedroom is a strong predictor of pediatric obesity.
  3. Cultural: Many societies follow either a healthier food palate (traditional oriental, Mediterranean, etc.) or eat smaller portions of higher-fat-content foods (European). The Americanization of such foods coupled with excessive portions is a prime cause of obesity.
  4. Diseases: Thyroid disease, polycystic ovary disease, brain tumors, mental retardation, and other conditions are a small contributor to the risk factors for obesity.
  5. Medications: Chronic oral steroids, some classes of antidepressants, and other drugs may also contribute (in a very small way) to pediatric obesity.
  6. Psychological: Many individuals overeat in an attempt to deal with emotionally stressful lifestyles. Often the excessive weight further aggravates their emotional turmoil.

What the risks, complications, and long-term health effects of childhood obesity?

The consequences of childhood obesity may be grouped into three areas: physical, mental, and economic. The known physical side effects of obesity are multiple and broad spectrum in character. These include: (1) increase in risk of developing type 2 diabetes mellitus due to excessive insulin secretion and organ resistance to insulin; (2) menstrual irregularity and infertility; (3) heart attack and stroke due to hypercholesterolemia, hyperlipidemia, and hypertension; (4) pulmonary issues centering on asthma and obstructive sleep apnea; (5) orthopedic issues of bowed legs and hip instability (for example, slipped capital femoral epiphysis); and (6) metabolic issues (nonalcoholic fatty liver disease, gallstones and gastroesophageal reflux [GERD]).
Equally as important as these physical side effects of obesity are the psychological consequences. These include (1) lowering of self-esteem often reinforced by teasing and bullying at school as well as a recurring barrage of the normal/ideal physique displayed by the media and entertainment industries and (2) depression, leading to possible further eating or an exaggerated overcorrection leading to eating disorders such as bulimia and anorexia nervosa.
The economic costs of childhood obesity are not often considered but are very important. Such effects include: (1) the direct costs of medical office visits, diagnostic studies and therapeutic services; and (2) indirect costs are both long- and short-term and include decrease in productivity, absenteeism, and premature death. Estimates for both direct and indirect costs for 2008 were $147 billion.

What is the treatment for childhood obesity?

The treatment for childhood obesity is no different than many diseases -- determine the cause and control or eradicate it. Since the overwhelming number of obese individuals are consuming too many calories relative to their energy expenditure ("burning them off"), therapy is directed toward reversing this metabolic equation. Simply put, consume fewer calories and use more up. There are many dietary programs that attempt to address this issue. None is superior over the long term unless the participant embraces these nutritional changes as part of a larger lifestyle recommitment. Drugs and surgery should be restricted to severe cases of childhood (and adult) obesity.

Can childhood obesity be prevented?

Benjamin Franklin's famous dictum "an ounce of prevention is worth a pound of cure" is ironically the perfect approach to childhood obesity. The CDC has recently raised the notion that should the alarming increase in childhood obesity not be reversed, the consequences may make the current pediatric population be the first generation to not exceed the life span of their parents. Studies have indicated that childhood obesity must be attacked prior to the teen years. Twenty percent of obese 4-year-old children will grow up to become obese adults; 80% of obese teens will continue their obesity into adulthood. All of the above reviewed consequences of pediatric obesity are brought forward into the adult years. Two amazing observations: (1) children 6 months to 6 years of age watch an average of two hours of television per day; (2) children 8-18 years of age spend an average of seven and a half hours per day involved with entertainment media activity such as television, computer games, video games and cell phone calls/texting.
Social and cultural changes are necessary to effectively address the pediatric obesity epidemic. A basic approach would entail the following:
  1. Advocate breastfeeding during the first year of life. Studies strongly reinforce that breastfed children have a lower risk of infant, childhood, and adolescent obesity.
  2. Drastically overhaul the school breakfast and lunch programs to favor heart-healthy food choices. Encouraging salad bars, banning sugar drinks, and flavored milk are options.
  3. Guarantee safe neighborhood environments which foster outside play activities.
  4. Limit TV/computer/social-network communication or other activities which encourage sedentary behaviors.
  5. Encourage vigorous physical education programs for 45 minutes daily.
  6. Revamp restaurant portion sizes. Studies had repeatedly demonstrated a link to the rise in pediatric obesity with fast-food restaurants' adoption of supersized portions as well as the bundling of food options (for example, deals for hamburger, french fries, and soda meals).
  7. Encourage the development of activity-friendly infrastructure in communities -- bike lanes, regional parks, etc. Many studies have shown that the social and cultural changes above must be accompanied by a strong family and community support structure, without which these approaches often fall short.

Childhood Obesity

Childhood obesity facts

  • Adult and childhood obesity has increased substantially in the last 30 years. Currently, 31% of adults and 18% of children at obese, as defined by excess body mass index (BMI).
  • The vast majority of obesity represents an imbalance in calories ingested vs. calories expended. Other causes of obesity (metabolic, medicines, and other diseases) are very rare.
  • Loosing body fat requires both caloric restriction and daily vigorous exercise.
  • The immediate and long-term effects of obesity include physical, psychological, and economic issues.
  • Obesity prevention will require both a personal and social/cultural change in lifestyle. A large volume of current research will help clarify what will be most helpful. 

What is childhood obesity?

In order to systematically describe obesity, the concept of body mass index (BMI) was developed. BMI is the ratio between an individual's weight to height relative to their gender and age. BMI addresses the following question: Is the weight of the subject in excess of what is healthy for a given height? Generally (but not always), BMI correlates with the amount of body fat, but it is not a measurement of fat. An individual who has more than the average muscle mass for a given height (for example, weight lifters, some athletes) will have an elevated BMI but clearly will not be obese. Nomograms for both adults and children have been developed to graphically represent the range of normal when measuring BMI. An individual is overweight when their BMI is between 25.0-29.9. Obesity is defined as a BMI greater than 30.0. Many web sites have calculators to measure BMI (for example, http://www.cdc.gov/
healthyweight/assessing/bmi/). Measuring body fat may be done via skin-fold-thickness measurement, waist-to-hip-circumference ratio and neutral buoyancy (water displacement) measurements. BMI is not used for children under 2 years of age.

How prevalent is childhood obesity?

The national statistics regarding childhood obesity prevalence (total number of cases in the pediatric population) have risen remarkably. In the 1970s and 1980s, approximately 5% of children were obese. By 2000, over 13% were obese, and 2009 statistics indicate pediatric obesity to be leveling off at approximately 18% of the population. (In contrast, approximately 31% of adults are obese.) While the frequency of obesity appears to be leveling off, the amount of excess weight has continued to rise (for example, BMI value has risen higher per individual).
The Midwest and South have the highest frequency of obesity (28%), with Mississippi the highest frequency (34%) and Colorado the lowest (18%). Of the remaining states, 24 have an obese population of over 25%; nine states have over 30% of their population being obese. In 2000, no states had more than 30% of their population considered obese.
The Center for Disease Control and Prevention's web site (http://www.cdc.gov) has an excellent demonstration of the rise in obesity over the last 30 years by using an interactive map of the United States (http://www.cdc.gov/obesity/data/
trends.html#State).
An area of concern is that the statistics gathered in many studies are self-reported by the individual and may therefore be overly optimistic (for example, purposely underestimating weight and overestimating height).

What causes childhood obesity?

Most obesity is caused by excessive daily caloric intake relative to daily caloric expenditure. Excessive intake of calories is most commonly associated with poor food-quality choices (for example, fast food high in fat calories) but may also result from over-ingestion of "healthy foods." The simple biological fact is that all excessive calories (regardless whether triple cheese meat lovers pizza vs. fat free yogurt with berries) will be stored by the body and only as fat. Attempts at only reducing caloric intake without increasing caloric utilization (read: 30 minutes daily vigorous exercise) will only help temporarily. If calorie restriction is the sole approach toward losing weight, the body's metabolism adopts a conservation mode and learns how to get by on fewer calories. Adding physical activity to the calorie-burning equation encourages breakdown of excessive carbohydrate and fat stores allowing for more functional and long-term health.
Body weight (not necessarily excessive body fatness) is a reflection of genes, metabolism, behaviors, culture, and socioeconomic status. These relatively infrequent causes of obesity will be detailed below.

What are childhood obesity symptoms and signs?

Measurement of height and weight are the most commonly used tools to quickly evaluate the proportionality of children. These measurements allow calculation of the body mass index (BMI). It is important to consider the physique of the individual. While having a weight in excess of what would be expected for a certain height is most commonly a documentation of excessive fat tissue, certain individuals may be overmuscled (for example, weight lifters). With the exception of very rare bone diseases, the idea of an individual's excessive weight due to being big boned is an urban myth.

What about bed bugs in hotels?

Many news reports in recent years have focused on the discovery of bed bugs in upscale hotels, and a number of lawsuits have been filed by guests in these fashionable hotels who awoke to find hundreds of bed bug bites covering their skin. Searching on TripAdvisor and other travel-review web sites regularly reveals information and even photos confirming the presence of bed bugs in numerous hotels.
Since the bed bugs can arrive on the clothing or in the suitcases of guests from infested homes or other hotels harboring the pests, hotels can be an easy target for bed bug infestations.

How are bed bugs spread?

Bed bugs live in any articles of furniture, clothing, or bedding, so they or their eggs may be present in used furniture or clothing. They spread by crawling and may contaminate multiple rooms in a home or even multiple dwellings in apartment buildings. They may also be present in boxes, suitcases, or other goods that are moved from residence to residence or from a hotel to home. Bed bugs can live on clothing from infested homes and may be spread by a person unknowingly wearing infested clothing.

What are the symptoms and signs of bed bug bites?

Bed bugs bite and suck blood from humans. Bed bugs are most active at night and bite any exposed areas of skin while an individual is sleeping. The face, neck, hands, and arms are common sites for bed bug bites. The bite itself is painless and is not noticed. Small, flat, or raised bumps on the skin are the most common sign; redness, swelling, and itching commonly occur. If scratched, the bite areas can become infected. A peculiarity of bed bug bites is the tendency to find several bites lined up in a row. Infectious disease specialists refer to this as the "breakfast, lunch, and dinner" sign signifying the sequential feeding that occurs from site to site.
Bed bug bites may go unnoticed or be mistaken for flea or mosquito bites or other types of rash or skin conditions, since they are difficult to distinguish from other bites. Bed bugs also have glands whose secretions may leave odors, and they also may leave dark fecal spots on bedsheets and around their hiding places (in crevices or protected areas around the bed or anywhere in the room).
Bed bugs have not been conclusively proven to carry infectious microbes. However, researchers have implicated bed bugs as possible vectors of American trypanosomiasis (Chagas disease), and studies are ongoing to determine whether bed bugs may serve as disease carriers.

What is the treatment for bed bug bites?

Typically, no treatment is required for bed bug bites. If itching is severe, steroid creams or oral antihistamines may be used for symptom relief. Secondary bacterial infections that develop over heavily scratched areas may require the use of antibiotics.

How do I detect a bed bug infestation in my home?

You can look to see if you can identify the fecal stains, egg cases, and exuviae (shed skins) in crevices and cracks on or near beds. You should also look at other areas such as under wallpaper, behind picture frames, in couches and other furniture, in bedsprings and under mattresses, and even in articles of clothing. While fecal stains and skin casts suggest that bed bugs have been present, these do not confirm that the infestation is still active. Observing the bed bugs themselves is definitive confirmation that an area is infested. You may require professional assistance from a pest-control company in determining whether your home contains bed bugs.

How do I get rid of bed bugs in the home?

Getting rid of bed bugs is not an easy process, and most cases of bed bug infestation will require treatment by a pest-control expert. A variety of low-odor sprays, dusts, and aerosol insecticides can be used to eradicate bed bugs. These must be applied to all areas where the bugs are observed as well as spaces where they may crawl or hide. The pest-control company can help you determine if the mattress can be disinfected or must be discarded. Since beds cannot readily be treated with insecticides, it's often necessary to discard infested mattresses and beds.
The pest-control expert may recommend certain forms of deep-cleaning such as scrubbing infested surfaces with a stiff brush to remove eggs, dismantling bed frames and furniture, filling cracks in floors, walls, and moldings, encasing mattresses within special bags, or using a powerful vacuum on cracks and crevices.

What about prevention of bed bug bites?

Avoidance of infested areas is the method for prevention of bed bug bites. Recognition of bed bug infestation and proper treatment of affected rooms (usually with the help of a pest-control specialist) is the best way to prevent bed bugs in the home. Those concerned about the potential for bed bugs bites in hotels should examine hotel beds and mattresses for signs of a bed bug infestation. Sealing your mattress in a bed bug prevention casing can be beneficial.
Bed Bugs At A Glance
  • Bed bugs are small, oval, non-flying insects that feed by sucking blood from humans or animals.
  • Bed bugs can live in any area of the home and can reside in tiny cracks in furniture as well as on textiles and upholstered furniture. They tend to be most common in areas where people sleep and generally concentrate in beds, including mattresses, boxsprings, and bed frames.
  • Bed bugs are most active at night and bite any exposed areas of skin while an individual is sleeping. The face, neck, hands, and arms are common sites for bed bug bites.
  • A bed bug bite is painless and is not noticed. Small, flat, or raised bumps on the skin are the most common sign; redness, swelling, and itching commonly occur.
  • Typically, no treatment is required for bed bug bites. If itching is severe, steroid creams or oral antihistamines may be used for symptom relief.
  • Fecal stains, egg cases, and exuviae (shed skins) of bed bugs in crevices and cracks on or near beds are suggestive that bed bugs may be present, but only observing the bugs themselves can confirm an active infestation.
  • A professional pest-control company may be required to help identify and remove bed bugs from the home.
