Treatment For Eating Disorders

Types of Eating Disorders

You can recover from an eating disorder, but it may take time and recovery will be different for everyone.

If you’re referred to an eating disorder specialist or team of specialists, they’ll be responsible for your care.

They should talk to you about the support you might need, such as for other conditions you have, and include this in your treatment plan.

Your treatment will depend on the type of eating disorder you have, but usually includes a talking therapy.

You may also need regular health checks if your eating disorder is having an impact on your physical health.

Your treatment may also involve working through a guided self-help programme if you have bulimia or binge eating disorder.

Most people will be offered individual therapy, but those with binge eating disorder may be offered group therapy.

Signs Of Bulimia Nervosa

People with bulimia nervosa have episodes of eating large amounts of food followed by purging , fasting, or exercising excessively to compensate for the overeating.

Unlike anorexia, people with bulimia are often a normal weight. But they have the same intense fear of gaining weight and distorted body image. They see themselves as âfatâ and desperately want to lose weight. Because they often feel ashamed and disgusted with themselves, people with bulimia become very good at hiding the bulimic behaviors.

The following are common signs of bulimia:

  • Evidence of binge eating, including disappearance of large amounts of food in a short time, or finding lots of empty food wrappers or containers
  • Evidence of purging, including trips to the bathroom after meals, sounds or smells of vomiting, or packages of laxatives or diuretics
  • Skipping meals or avoiding eating in front of others, or eating very small portions
  • Exercising excessively
  • Wearing baggy clothes to hide the body
  • Complaining about being âfatâ
  • Using gum, mouthwash, or mints excessively
  • Constantly dieting
  • Scarred knuckles from repeatedly inducing vomiting

Six Of The Most Common Types Of Eating Disorders

After collating a series of national surveys, the National Eating Disorders Association estimates that, in America alone, approximately 20 million women and 10 million men will suffer from an eating disorder at some point in their lifetime.

Unfortunately, despite the fact that eating disorders are on the rise all around the world, the general public still has a lot of misconceptions when it comes to signs, symptoms, and types of eating disorders. To help dispel some of these misconceptions, this article will briefly outline six of the most common types of eating disorders.

1. Anorexia Nervosa

Anorexia nervosa is perhaps the most recognized type of eating disorder. According to NEDA, anorexia nervosa is more common among women and typically emerges during early adulthood or late adolescence.

People with anorexia nervosa may exhibit the following symptoms:

  • Being abnormally underweight with respect to height and age weight criteria.
  • Having obsessive thoughts regarding thinness and being thinner.
  • Having an extreme fear of gaining weight.
  • Shunning meals with other people.
  • Basing self-esteem on distorted ideas of body image.

Medical experts recognize two distinct types of anorexia nervosa:

Binge eating and purging: This type of anorexia drives people to purge their food after a binge eating episode. The most common methods of post-binge purging are self-induced vomiting or misuse of laxatives.

2. Bulimia Nervosa

  • Acid reflux
  • Dangerously elevated electrolyte imbalances

Other Eating Disorders And Eating Problems

Eating disorder and four types of eating

Other specified feeding and eating disorder

OFSED means you have symptoms of an eating disorder, but you dont have all the typical symptoms of anorexia, bulimia or BED. You may have a mixture of symptoms from different eating disorders. This doesnt mean that your illness is less serious.

Emotional overeating

You turn to food when you have negative feelings if you are an emotional overeater. These can be feelings like anxiety or sadness. Eating food may help you to feel comforted.

Lots of people use food to help manage feelings, this is normal. But it may become a problem if this is the only management technique that you have, or you are beginning to feel out of control. Emotional overeating can cause feelings of guilt and shame.


With pica, you eat non-food objects such as chalk, paint, stones and clothing. There is no nutritional benefit from eating these items and some can be harmful. Pica can lead to further health concerns such as dental and stomach problems.

Rumination disorder

You will chew and spit out food without swallowing it if you have rumination disorder. You may do this repeatedly.

Selective eating disorder

You will only eat certain foods and may refuse to try other foods if you have SED. This is common in young children. But the problem can continue into adulthood.

What Are the Treatment Options? | Eating Disorders

People with anorexia nervosa have an extreme fear of gaining weight. They often diet and exercise relentlessly, sometimes to the point of starvation. About one-third to one-half of anorexics also binge and purge by vomiting or misusing laxatives. People with anorexia have a distorted body image, thinking they are overweight when in fact they are underweight. They may count calories obsessively and only allow themselves tiny portions of certain specific foods. When confronted, someone with anorexia will often deny that thereâs a problem.

The signs of anorexia can be subtle at first, because it develops gradually. It may begin as an interest in dieting before an event like a school dance or a beach vacation. But as the disorder takes hold, preoccupation with weight intensifies. It creates a vicious cycle: The more weight the person loses, the more that person worries and obsesses about weight.

The following symptoms and behaviors are common in people with anorexia:

Reasons for non-response to interviewing include: refusal to participate respondent was reluctant- too busy but did not refuse circumstantial, such as intellectual developmental disability or overseas work assignment and household units that were never contacted .

Avoidant/restrictive Food Intake Disorder

Avoidant/restrictive food intake disorder is characterized by severely limiting your diet and eating only certain kinds of food. Previously, this condition was called selective eating disorder.

However, ARFID isnt just extreme picky eating. With ARFID, you may avoid certain foods or entire food groups. You may also seriously restrict the overall amount of food you eat in general.

ARFID often stems from a fear of something bad happening when you eat, like poisoning, choking, or vomiting.

Sometimes, ARFID can be connected to sensory disorders as well as autism spectrum disorder . People with ARFID might limit their eating to avoid foods with certain features they might be sensitive to, such as:

  • colors
  • low energy from inadequate nutrition
  • intolerance for cold temperatures
  • gastrointestinal issues, like stomach pain or constipation

ARFID can progress to a point where a feeding tube or supplements are necessary to deliver essential, life-sustaining nutrients.
