When people talk about ADHD and food, the usual story is forgetting to eat lunch because you got absorbed in something. A new study from France points somewhere else, and it suggests that many people in eating disorder care have ADHD that nobody has named.
Researchers at Esquirol Hospital in Limoges assessed 120 adults who were being treated for an eating disorder. In the study published September 29, 61 of them met the criteria for ADHD. Only two had a confirmed diagnosis before.
Most of them had never been told
Everyone in the study filled in a short, standard ADHD screening questionnaire. Those who screened positive then had a structured interview with a psychiatrist, the kind used for adult diagnosis, which asks about attention and restlessness in childhood as well as now.
Just over half met the criteria. For 59 of those 61 people, it was the first time anyone had confirmed it, even though they were already in specialist care.
That gap is the story. These were adults already seeing clinicians about their eating, and the attention side of things had stayed invisible.
The number itself needs care, and the authors say so. Earlier studies of people with eating disorders mostly found ADHD in 10 to 20 percent. This hospital takes the most complex cases in its region, and almost half of the participants were inpatients, which probably pushed the figure up.
Two more limits matter. Being seriously unwell with an eating disorder can itself affect attention and memory, and childhood signs were recalled from memory with no parent or school record to check them. The study shows that ADHD can go unnoticed inside eating disorder care. It does not tell you how common ADHD is among everyone who struggles with food.
The link was strongest with binge eating, not restriction
If ADHD mainly made people forget meals, you might expect the strongest overlap with restrictive eating. The researchers found the opposite pattern.
About seven in ten people with bulimia nervosa or binge-eating disorder met the criteria for ADHD, compared with fewer than half of those with anorexia nervosa. The groups were small, 27 and 13 people, so treat the exact shares as rough.
People with ADHD in the study also scored higher on impulsivity and on dissatisfaction with their bodies, and more of them had another mental health condition, most often depression. Their personality profiles differed too: they were more sensitive to approval and reward, and scored lower on feeling in control of their own direction.
When the researchers put all of these factors into one model, only the type of eating disorder still stood out. The other differences are worth knowing about, but they are less certain.
That fits a picture many people with ADHD already know from other parts of life: it is not only about where attention goes, it is about how hard it is to wait, pause, or stop once something is pulling at you. The study measured these things at one point in time. It did not show that ADHD causes eating problems.
If you are already in treatment, ADHD is worth naming
The authors conclude that eating disorder services should screen for ADHD, especially in people with bulimia nervosa and binge-eating disorder, and use treatments that also address impulsivity and attention.
If you are being treated for an eating disorder and have always struggled with focus, restlessness, or acting before thinking, it is reasonable to raise ADHD with your care team. They can decide whether an assessment makes sense, and how it would fit with the rest of your treatment.
Questions like this are easy to forget once you are in the room, so write down what you want to ask beforehand. In Recordo, you can keep it as a note and add a task with a reminder on the day of your appointment, so the note is in front of you when it matters.
If eating feels out of your control right now and you are not getting support, a doctor or an eating disorder helpline in your country is the place to start. You do not need to know whether ADHD is part of it first.

A care plan can only treat what someone has named
Fifty-nine people in this study had a part of their story that no confirmed diagnosis had captured. Nothing about them changed when it was named. What changed is that the people treating them could finally see it.
This article reports on one study. It is not a diagnosis or medical advice, and it cannot tell you whether you have ADHD or an eating disorder.
