Eating disorders are generally considered and diagnosed in neurotypical people, but did you know they can affect persons with IDD as well? Although serious and sometimes fatal, they are treatable.
The person typically has an uncommon relationship with food. It can be portrayed in their actions, their justification for it or it can be their lover, comforter and friend. Eating disorders can also stem from distorted perceptions of weight and body image. Females are more often affected than males.
Many people do recover from eating disorders but may relapse during stressful periods in their life.
Anxiety, depression, substance abuse and obsessive-compulsive tendencies often occur in combination with eating disorders. Anxiety is the most frequently seen in connection with an eating disorder.
Here are some eating disorders that you may see:
- Anorexia NervosaThis is identified by a significant weight loss and a skewed view of body image. There is often denial that there is a problem and the person doesn’t recognize the seriousness of the disease.
- Avoidant Restrictive Food Intake DisorderThis describes a very, very “picky” eater which often results in a significant lack of nutrients and calories for cellular health and overall body health.
- Binge EatingBinging is eating a large amount of food within 2 hours or less, significantly more than others would eat. The person has the feeling of loss of control during a binge and strong feelings of guilt and shame after the binge. Binge Eating is the most common eating disorder in the U.S.
- Body Dysmorphic DisorderThe person focuses on one area on, or part of, the body and sees a serious “flaw(s). The area or “flaw” is generally not noticed by others. They feel ugly and deformed and “fat” when they are within their normal weight. They are constantly comparing their body to others and are obsessed with checking mirrors, excessive clothing changes and application of makeup.
- Bulimia NervosaBulimia is binge eating with compensatory behaviors to eliminate the calories they consumed. These compensatory measures may be vomiting immediately after binging or taking excessive diuretics and laxatives. Bulimia is not necessarily about the food or its comfort, but more about body image.
- NeophobiaNeophobia is the fear of trying any new foods and rejecting food when it is served before it is even tasted. This can sometimes be related to the presentation, form and smell of foods.
- PicaA person eats nonnutritive substances for at least 1 month. The more severe the disability, the more likely it is for the person to have pica. Some pica can be related to nutrient and mineral deprivation, especially iron and zinc. Pica is strongly associated with disorders of the GI tract.
- Purging DisordersPurging disorders occur in the absence of binging. Purging can take the form of self-induced vomiting, over-use of laxatives, diuretics or enemas.
- RuminationIt is generally defined as chewing and re-swallowing prior ingested food. It can also be the voluntary and repetitive expulsion of regurgitated stomach contents. It can occur across the lifespan and is more common in persons with IDD. It is often misdiagnosed, in some cases 2 years. Generalized anxiety disorder often accompanies rumination.
- Super TasterThis person has a sense of taste that is a higher intensity than others. A super taster typically has a more intense taste to bitter, fatty or very sweet items. They may eat more salt to counteract the bitterness. The person also may be very sensitive to hot, spicy food because pain receptors surround the taste buds.
The primary goal when treating a person with an eating disorder is to first treat the malnutrition and the underlying damage caused to organs when possible. Many people do recover from eating disorders but may relapse during stressful periods in their life.

Aspiration is usually listed as the most common cause of death in institutional settings, including nursing homes and large group care settings for people with IDD. Aspiration pneumonia is a common discharge diagnosis following hospitalization. It occurs when bits of food or liquids make their way into the windpipe instead of into the esophagus where it should be. Aspiration can occur during the swallowing process, but also occurs when stomach contents come back up the esophagus as a result of vomiting or gastroesophageal reflux. It often begins subtly and damages increasing portions of the lungs. Feeding tubes, which carry their own increased risks, are often utilized in an attempt to bypass the swallowing process and reduce aspiration episodes, but are not always entirely effective. Other factors which may lead to aspiration are poor body positioning, particularly in individuals who cannot control their own movements well, and behavioral issues related to eating. One of the most common signs of aspiration is a cough noted during eating or drinking or shortly thereafter. When a cough is noted under these conditions an evaluation should be initiated to look for possible aspiration.
Constipation and Bowel Obstruction are almost always at the top of the list of causes of illness and preventable death in people with IDD. One of the most important root causes of bowel obstruction is the use of multiple drugs with constipating side effects. Add to this the fact that most of us have dietary habits that contribute to the problem, chief among them, diets that are low in fiber and adequate fluids. Lack of mobility is a contributing factor to constipation, as well. We often see people on one or more medications to help improve elimination, but ironically, drugs intended to improve constipation often place the person at higher risk for impaired bowel function. Adequate active movement or exercise is also important to bowel function. Controlling these factors, along with training caretakers to recognize the signs and symptoms of bowel problems at the earliest moment can greatly reduce occurrences of illness or death from bowel obstruction.
Seizure deaths can occur from episodes of prolonged, uncontrolled seizures as well as something called SUDEP or sudden unexplained death in epilepsy. For reasons that medical science has yet to explain, people who have epilepsy have a higher chance of dying suddenly unrelated to actual seizure activity. Drug toxicity and medication side effects can further impact the health and well-being of people who takethese medications, and the balance between adequately controlling someone’s seizures and the risk of adverse drug reactions must always be at the forefront of the treatment plan. Life expectancy for people with active seizure disorders has been shown to be up to 10 years less than those without epilepsy.
Dehydration is all too common and easily preventable in most cases. People who do not swallow well are particularly likely to refuse fluids or indicate fear when they get them, often resulting in dehydration. Dehydration is also likely when fluids are restricted in an attempt to prevent incontinence, not realizing that lack of fluids can contribute to constipation and increased seizure frequency, not to mention drug toxicity and other health problems. Awareness of fluid loss through sweating in warm and humid conditions or from loss due to vomiting or persistently elevated blood glucose levels in people with diabetes is important, as well. The presence of fever also increases a person’s fluid needs. Anyone supporting people with IDD should be aware of a person’s fluid requirements and work to ensure that they receive the necessary fluids to prevent dehydration.
Sepsis, sometimes called “the silent killer” is an ever-present threat to all. Sepsis is a condition which results from a significant infection in the bloodstream and the body’s response to that infection. Early signs of sepsis include fever, chills, rapid heart rate, low blood pressure and mental status changes. Some of these symptoms are common with may illnesses, but one’s index of suspicion should remain high for worsening signs of a serious infection and referral for a medical evaluation should be considered earlier rather than later. The risk of death increases significantly for each hour that passes when sepsis is left untreated. Remember, “When in doubt, send them out!”
Gastroesophageal reflux disease (GERD) is the backing up of stomach contents, including acid, into the esophagus. GERD is frequently undiagnosed in many people, including those without disabilities, until major harm has been done to the bottom of the esophagus. Medications that cause constipation also contribute to GERD. Individuals who are overweight, particularly when they carry excess weight around the abdomen or wear clothing that is too tight have a higher risk of GERD. Ill-advised dietary choices, immobility and improper positioning also contribute greatly to the incidence of GERD. As this disorder continues without treatment, discreet or frank aspiration, life-threatening gastrointestinal bleeding and esophageal cancer become increasingly common. Recognizing signs of GERD, especially in people who do not communicate with words, is important to reduce the risks associated with this condition. People who exhibit food refusal, coughing when lying down, physical or verbal aggression particularly around meal times, or distress in the middle of the night may be telling you that they are experiencing GERD. Pica, a behavior where people eat things of non-nutritional value, may also be a sign of GERD and should prompt an evaluation.
