ADHD isn’t just about distractibility or hyperactivity — it’s a whole-body, whole-life condition that affects how someone navigates emotions, relationships, and even their relationship with food or substances.
Let’s break down why ADHD makes people more vulnerable to eating disorders, substance use, and intense emotional struggles.
Interoception Issues: Struggling to Read the Body’s Signals
Interoception is your brain’s ability to sense what’s going on inside your body — hunger, fullness, thirst, tension, calmness.
People with ADHD often struggle with interoceptive awareness, which means they might:
Miss hunger or fullness cues until they’re extreme
Eat past satisfaction or forget to eat for long stretches
Struggle to notice emotions building until they explode
When you can’t tune into the body’s subtle signals, it’s harder to regulate both food and feelings — sometimes leading to binge eating, restrictive patterns, or emotional meltdowns.
Executive Functioning: Trouble With Planning and Regulation
Executive functioning includes skills like planning, organizing, impulse control, and follow-through — all areas where ADHD brains struggle.
This can look like:
Difficulty planning balanced meals or regular eating
Impulsive eating, drinking, or drug use
Trouble pausing to reflect before acting on strong urges or emotions
The brain craves quick relief — and food, substances, or numbing behaviors can feel like the fastest way to manage overwhelming internal states.
Social & Emotional Pain: Feeling Like You’re “Too Much” or “Not Enough”
Many people with ADHD grow up feeling like they’re always messing up, disappointing others, or needing to mask their real selves to fit in.
This chronic shame and rejection can lead to:
Using food, substances, or other coping behaviours to numb pain
Developing perfectionistic or restrictive patterns to feel “in control”
Avoiding or suppressing vulnerable emotions because they feel overwhelming
Eating disorders, addictions, and emotional shutdowns can be powerful (but temporary) ways to avoid the pain of feeling like a problem.
The Good News: You’re Not Broken — You’re Wired Differently
If you have ADHD and struggle with eating, substances, or intense emotions, it’s not because you’re weak or lazy — it’s because your nervous system and brain wiring make certain types of regulation harder.
With the right support — like ADHD-informed therapy, nervous system tools, skill-building, and lots of self-compassion — you can build healthier, more sustainable ways of caring for your body and emotions.
