Feeding and eating disorders are serious mental health conditions that affect how people relate to food, body weight, and body image. Unlike occasional dieting or overeating, these disorders involve persistent, harmful patterns that interfere with physical health, emotional well-being, and daily life. They can occur at any age, though they often begin in adolescence or early adulthood.
Globally, eating disorders affect at least 70 million people, and they are among the deadliest mental health conditions due to medical complications and high suicide risk. In the United States, around 9% of the population will experience an eating disorder in their lifetime. With proper diagnosis and treatment—including therapy, nutritional counseling, and sometimes medication—recovery is possible.
Here are the three most common feeding and eating disorders:
Anorexia Nervosa
Anorexia nervosa is characterized by extreme restriction of food intake, intense fear of gaining weight, and a distorted body image. Despite being underweight, individuals often see themselves as overweight. Anorexia has one of the highest mortality rates of any psychiatric disorder, largely due to starvation and related medical complications.
Symptoms:
Treatment:
Treatment usually involves a combination of medical care, nutritional rehabilitation, and psychotherapy. Family-based therapy is especially effective for adolescents. Antidepressants may be prescribed for co-occurring depression or anxiety, though no single medication directly cures anorexia.
Prevalence:
About 0.3–1% of women and 0.1% of men are affected. That translates to several million cases worldwide.
Bulimia Nervosa
Bulimia nervosa involves cycles of binge eating followed by compensatory behaviors such as vomiting, fasting, excessive exercise, or misuse of laxatives. Unlike anorexia, people with bulimia may have a normal body weight, making the disorder harder to detect.
Symptoms:
Cognitive Behavioral Therapy (CBT) is the most effective treatment, focusing on breaking the binge-purge cycle. Antidepressants, particularly SSRIs like fluoxetine, are often prescribed. Nutritional counseling also plays an important role.
Prevalence:
Around 1–1.5% of women and 0.5% of men are affected in their lifetime. Millions live with bulimia worldwide, often undiagnosed.
Binge-Eating Disorder (BED)
Binge-eating disorder is the most common eating disorder. It involves repeated episodes of eating unusually large amounts of food without engaging in purging behaviors. People with BED often feel guilt, shame, or distress about their eating habits, which can lead to obesity and related health problems such as diabetes and heart disease.
Symptoms:
Treatment:
CBT and interpersonal therapy are effective in reducing binge episodes. Medications such as lisdexamfetamine (Vyvanse) and SSRIs may also be prescribed. Lifestyle changes, including regular exercise and structured eating patterns, support long-term recovery.
Prevalence:
BED affects about 2–3% of adults worldwide, making it more common than anorexia and bulimia combined. In the United States alone, around 3.5% of women and 2% of men are affected.
Conclusion
Feeding and eating disorders are complex conditions that can impact both mental and physical health. Anorexia nervosa, bulimia nervosa, and binge-eating disorder are the most common, each with unique symptoms but often linked by struggles with body image and control. Although these disorders are serious, effective treatments exist, and recovery is possible with timely support.
Raising awareness, reducing stigma, and encouraging open conversations about food and body image are key steps in helping people seek help earlier. With therapy, medical care, and strong social support, many individuals go on to live healthier and more fulfilling lives.

Despite being underweight, individuals often see themselves as overweight. Anorexia has one of the highest mortality rates of any psychiatric disorder, largely due to starvation and related medical complications.
Symptoms:
- Severe restriction of food intake
- Intense fear of weight gain
- Distorted perception of body size or shape
- Excessive exercise or strict dieting
- Low body weight compared to age and height
Treatment:
Treatment usually involves a combination of medical care, nutritional rehabilitation, and psychotherapy. Family-based therapy is especially effective for adolescents. Antidepressants may be prescribed for co-occurring depression or anxiety, though no single medication directly cures anorexia.

Bulimia nervosa involves cycles of binge eating followed by compensatory behaviors such as vomiting, fasting, excessive exercise, or misuse of laxatives. Unlike anorexia, people with bulimia may have a normal body weight, making the disorder harder to detect.
Symptoms:
- Recurrent episodes of eating unusually large amounts of food in a short time
- Feeling a lack of control during binges
- Engaging in behaviors to prevent weight gain (vomiting, fasting, or laxative use)
- Preoccupation with body shape and weight
- Possible dental erosion, throat irritation, or gastrointestinal issues from purging

People with BED often feel guilt, shame, or distress about their eating habits, which can lead to obesity and related health problems such as diabetes and heart disease.
Symptoms:
- Eating much more quickly than normal
- Eating until uncomfortably full
- Eating large amounts of food even when not hungry
- Eating alone due to embarrassment
- Feeling guilt or disgust after overeating
Treatment:
CBT and interpersonal therapy are effective in reducing binge episodes. Medications such as lisdexamfetamine (Vyvanse) and SSRIs may also be prescribed. Lifestyle changes, including regular exercise and structured eating patterns, support long-term recovery.
