What Are the Different Types of Eating Disorders?Understanding the Spectrum — Because Eating Disorders Aren’t One-Size-Fits-All

When most people hear the term “eating disorder,” they tend to picture extreme thinness or assume it’s all about food. But eating disorders are complex mental health conditions that affect people of all body sizes, genders, ages, and backgrounds — and they don’t all look the same.

Whether you’re a parent, provider, or someone seeking answers, it’s important to understand the different types of eating disorders. Recognizing the signs is the first step toward healing.

What Is an Eating Disorder?

Eating disorders are psychological illnesses involving disturbed eating behaviors and distress around food, body image, or weight. They can lead to serious medical complications and are often co-occurring with anxiety, depression, trauma, or perfectionism.

According to the DSM-5 (Diagnostic and Statistical Manual of Mental Disorders), here are the main types of eating disorders:

1. Anorexia Nervosa

A disorder marked by severe food restriction, intense fear of weight gain, and distorted body image.

Key Features:

• Restriction of energy intake → significantly low body weight

• Intense fear of gaining weight

• Body image disturbance or denial of seriousness of low weight

There are two subtypes:

• Restricting type

• Binge-eating/purging type

📌 Important: People with anorexia can be underweight or within “normal” ranges (known as atypical anorexia).

2. Bulimia Nervosa

Characterized by recurrent episodes of binge eating followed by compensatory behaviors like vomiting, excessive exercise, or laxative use.

Key Features:

• Eating large amounts in a short period with a sense of loss of control

• Purging or fasting afterward to avoid weight gain

• Occurs at least once a week for 3 months

People with bulimia often appear healthy, making it harder to detect.

3. Binge Eating Disorder (BED)

Marked by recurring episodes of binge eating without purging, often accompanied by shame and guilt.

Key Features:

• Eating unusually large amounts in one sitting

• Feeling out of control

• Eating rapidly, in secret, or when not hungry

• Intense distress afterward

BED is the most common eating disorder, affecting people of all sizes and backgrounds.

4. Avoidant/Restrictive Food Intake Disorder (ARFID)

ARFID involves extreme food avoidance or restriction, but without body image concerns.

Key Features:

• Strong sensitivity to textures, tastes, smells

• Fear of choking, vomiting, or allergic reactions

• Lack of interest in food or eating

• Nutritional deficiencies or weight loss

Common in children and neurodivergent youth, but can affect all ages.

5.Other Specified Feeding or Eating Disorder (OSFED)

A category for people with significant eating disorder symptoms that don’t fit neatly into the criteria for anorexia, bulimia, or BED.

Examples include:

• Atypical anorexia (all signs of anorexia but with “normal” weight)

• Subthreshold bulimia or BED

• Purging disorder (purging without bingeing)

• Night eating syndrome

OSFED is just as serious and impairing as other eating disorders.

6.Unspecified Feeding or Eating Disorder (UFED)

Used when symptoms cause distress or impairment but don’t meet full criteria for another disorder — or if there’s not enough information for a more specific diagnosis (e.g., in emergency settings).

Other Patterns of Disordered Eating

Some behaviors don’t meet diagnostic criteria but still deserve attention:

• Orthorexia: Obsession with “clean” or “perfect” eating

• Chew-and-spit: Chewing food and spitting it out without swallowing

• Compulsive exercise or body checking

• Yo-yo dieting, fasting, or “detoxing”

These may develop into full eating disorders — and are always worth addressing early.

Final Thought

Eating disorders come in many forms — and none are “less real” than others. Whether someone is severely underweight or not, whether they’re restricting or bingeing, all disordered eating deserves support and care.

Recovery is possible — and it begins with understanding.
