There are ten major types of eating disorders. Although these revolve around impulsive eating and weight fluctuations, each has unique symptoms.
1. Bulimia Nervosa
Bulimia develops during adolescence or early adulthood and is seen mainly among women. Those who suffer from this condition eat a huge quantity of food in a very short period.
While binge eating, they can neither stop nor control their unusual consumption and keep eating until it hurts. People with Bulimia try to purge to compensate for their calorie intake by forced vomiting, fasting, excessive exercising, and using laxatives or diuretics.
Symptoms of Bulimia Nervosa
- Recurring binge eating episodes
- Purging behaviour
- Always having insecurity about body shape and weight
- Afraid of gaining weight
2. Anorexia Nervosa
This kind of eating disorder also happens between adolescence and adulthood. Similar to Bulimia, Anorexia occurs more among women than men. People with this ailment feel they are overweight even if they are not.
Anorexia has two subtypes. One is the restricting calorie intake type, and the other is the compulsive eating and purging type. This is a dangerous type of disorder which can damage one's body over time. It has been seen people with this disorder experience thinning of their bones, brittle hair and nails, and infertility.
Symptoms of Anorexia
- Restricted eating habits
- Despite being underweight, fear of becoming overweight
- Unwillingness to maintain a healthy lifestyle
- Influence of body weight on self-esteem
3. Binge Eating Disorder
Binge eating disorder, or BED, is one of the most prevalent forms of an eating disorder. In this psychological condition, people keep eating fast until they feel comfortable. Distress is a major trigger for this condition.
If someone binge eats once a week for three months, they have this disorder. This condition can occur in childhood or inherit this condition. Although many overlook this condition, it can have serious health risks if not treated promptly.
Symptoms of Binge Eating Disorder
- Eating secretly

4. Pica
Pica is a type of eating disorder where patients eat things which are either inedible or have no nutritional value. This condition can develop in anyone, irrespective of age.

5. Rumination Disorder
In this particular type of eating disorder, people regurgitate previously chewed food, re-chew it and then either swallow it or spit it out. People practices rumination within 30 minutes of their meal.
If this disorder develops in an infant, it will occur before they turn one and disappear on their own. However, if this is not taken care of, it can lead to severe malnutrition and weight loss. In the case of adults, they restrict eating outside due to shame and would require therapy to treat.
Symptoms of Rumination
- Bring food back to the mouth without nausea
