ADHD symptoms like impulsivity and trouble with focus can play a role in binge eating disorder (BED).
The eating disorder that overlaps most often with ADHD is BED.
If your child has
and also has an eating disorder, you may think the two are unrelated. But these two conditions often co-occur. Research shows a particularly strong link between ADHD and binge eating.

ADHD and binge eating disorder
There are a few types of eating disorders. These include anorexia, bulimia and binge eating disorder (BED). The condition that overlaps most with ADHD is BED. It’s also the most common eating disorder.
BED affects around 3.5 percent of women and 2 percent of men in the U.S. An estimated 30 percent of them have ADHD. Researchers believe that
like impulsivity and inattention play a role.
With BED, people often eat large amounts of food quickly, even when they’re full. Unlike with bulimia, they don’t try to purge the food by throwing up or through excessive exercise. But they do often feel shame afterward. (It’s important to know that obesity often co-occurs with both ADHD and BED.)
Experts believe that people with ADHD may overeat to satisfy their brain’s need for stimulation. Also, problems with
can make self-control and
Inattention can also be a factor. People with ADHD may not be as aware of or focused on their eating habits. They may not recognize when they’re hungry during the day, for example, and then end up overeating later on. They may also not pay attention to when they’re full, and keep on eating.
There also appears to be a genetic link. Researchers have identified common genes in people with ADHD, BED, and obesity. These genes are involved in transmitting a brain chemical called dopamine in the brain. With ADHD,
this transmission isn’t very efficient
ADHD, bulimia, and anorexia
The direct connection between bulimia and ADHD isn’t as strong as the one between BED and ADHD. But binge eating can be part of this type of eating disorder, too. So, it’s not uncommon for people to have both ADHD and bulimia.
When it comes to anorexia, studies show no link to ADHD. The behaviors of the two conditions are totally different. People with ADHD are impulsive. People with anorexia are compulsive. They restrict the amount of food they eat, instead of eating to excess.
Anxiety, depression, and eating disorders
Mental health issues can also contribute to eating disorders. Two of the most common,
anxiety and depression
, often co-occur with ADHD as well. So, kids with ADHD may be at even greater risk of an eating disorder if they also have other mental health issues.
Treating ADHD, eating disorders, and mental health issues
ADHD, eating disorders and mental health issues like anxiety need to be treated separately. But some treatments may help with more than just one of the conditions.
Stimulant medication for ADHD
may help with binge eating, for example. It can improve self-control. It also has the side effect of reducing appetite. If you’re considering
, talk to your child’s doctor about whether it may be right for your child.
Therapy is a key treatment for eating disorders and other mental health issues. It can also help with ADHD. One common type is
cognitive behavioral therapy
(CBT). Another is called dialectical behavior therapy (DBT).
It’s important to seek professional help for each of the conditions your child might have. Start by talking to your child’s doctor. From there, the doctor can refer you to mental health professionals.
