Food and eating play a central role on this site, and we've already covered some strange food and mental health conditions. This article takes it a step further by exploring odd psychological disorders connected to food or weight. If you can think of others or have any personal experiences with the ones listed here, we’d love to hear from you in the comments section.
10. Orthorexia

This condition is marked by an obsession with consuming only healthy foods, often mistaken for anorexia. The key difference lies in the motivation: Anorexics focus on weight loss, while orthorexics are driven by the desire for 'pure' or clean eating. Although not officially recognized by the DSM IV, orthorexia is becoming increasingly prevalent across the United States. You can read the heartbreaking account of a young woman who tragically succumbed to this disorder here.
9. Prader-Willi Syndrome

Prader-Willi Syndrome (PWS) results from a chromosomal abnormality. It is not inherited and affects individuals of any gender or race. The syndrome manifests with several symptoms, including motor skill impairments, stunted growth, and intellectual disabilities. One of its most dangerous features is an insatiable hunger, which, if not managed, can lead to life-threatening overeating. Treatment involves the use of growth hormones and a strict low-calorie diet. In 2005, a fictionalized portrayal of PWS appeared on the TV show CSI.
8. Pica

Pica stands out as one of the most intriguing conditions on this list, as it combines both an eating disorder and a mental health issue. Those who suffer from pica experience an overwhelming desire to consume items that are neither food nor nutritionally valuable. These could be anything from discarded cigarette butts to chunks of paint. The dangers of pica are severe, as the person may ingest toxic substances or sharp objects that can cause serious injury or even death.
7. Bigorexia

Bigorexia is often referred to as the opposite of anorexia, and it’s unique among eating disorders in that it affects more men than women. Individuals with bigorexia engage in intense workout regimens, take supplements, and significantly limit their food intake, yet they are never satisfied with their physical appearance. Despite having muscular and toned bodies, those struggling with this disorder feel embarrassed or inadequate about showing their bodies. Many men suffer in silence, as eating disorders have historically been seen as a problem primarily for women, leading to a lack of awareness and support for male sufferers.
6. Binge Eating Disorder

Binge eating is a distinct condition from bulimia, and it is considered one of the most prevalent eating disorders. Though it was categorized as a part of EDNOS (Eating Disorder Not Otherwise Specified) in the DSM IV, binge eating is a separate issue. Individuals with Binge Eating Disorder (BED) are not driven by the same passion for food as those with compulsive eating disorders. Much like anorexics and bulimics, binge eaters experience shame about their bodies and are often embarrassed by their eating behaviors.
5. Anorexia Athletica

Though not strictly classified as an eating disorder on its own, anorexia athletica is almost always present alongside another eating disorder. As implied by the name, individuals with anorexia athletica push beyond the typical post-exercise fatigue. This feeling isn't a choice for those with the condition, and they often go to extreme lengths, risking overexertion or injury, in their pursuit of achieving the ideal body.
4. Night Eating Syndrome

Night Eating Syndrome (NES) is a relatively new diagnosis, but it has been growing in recognition, much like orthorexia. Those affected by NES, typically obese or morbidly obese, tend to skip breakfast and consume very little throughout the day, often eating the majority of their calories during the night. They may also suffer from insomnia or wake up during the night to eat. As with other eating disorders, individuals with NES are often secretive about their habits and hesitant to acknowledge the issue.
3. Anorexia Nervosa

Recent studies indicate that around 1 in 100 teenage girls experience anorexia. This condition has even led to hospitalization in girls as young as 8. Brain scans of those with anorexia reveal that their compulsion to avoid food is as powerful as the addiction seen in individuals struggling with severe drug or alcohol dependency. Anorexics are particularly vulnerable to relapse because, like other addictions, anorexia and related disorders do not disappear completely. Individuals who have completed treatment and are symptom-free are considered to be in remission, though they must continue managing their impulses and cravings. A single triggering event can reignite the illness, even years after recovery. However, those who successfully control the disease can achieve full recovery and lead a normal life with a healthy relationship with food.

2. Bulimia Nervosa

Bulimia is defined by cycles of binge eating followed by purging. While most people associate bulimia with self-induced vomiting to purge, there are other methods as well. Bulimics may also use diuretics, enemas, or ipecac syrup to induce vomiting. Over-exercising is another common purging method. Bulimics are often very conscious of the abnormal and socially stigmatized nature of their behavior, leading them to hide it at all costs. Interestingly, bulimics with a relatively balanced binge-purge cycle tend to maintain a normal weight. It is only those who purge more than they binge who show the typical outward signs of an eating disorder.
1. Body Dysmorphic Disorder (BDD) is a mental health condition where an individual is excessively preoccupied with perceived flaws or defects in their physical appearance, which may not be noticeable to others, or are minor. Those affected often feel the need to hide or alter their appearance, leading to distress and social withdrawal. In extreme cases, it may severely impact daily life, making it difficult to maintain relationships or work.

BDD can be diagnosed independently of eating disorders (ED), although it often coexists with them. Despite improvement in other symptoms, BDD may persist, influencing the individual’s sense of self. Those suffering from BDD are convinced of having various physical imperfections such as being overweight, unattractive, or having flaws like poor hair, teeth, or odor, despite these issues being perceived differently by others. This condition goes beyond typical teenage insecurities about appearance, creating a distorted reality for those affected.
