Eating Disorders and Anxiety — The Deep Connection Between Them

Eating disorders — including anorexia nervosa, bulimia nervosa, binge-eating disorder, and avoidant/restrictive food intake disorder (ARFID) — have a profound relationship with anxiety disorders. Research consistently shows that anxiety disorders are highly prevalent in people with eating disorders: studies suggest 48-65% of people with eating disorders also meet criteria for an anxiety disorder.

How Anxiety and Eating Disorders Interact

Anxiety often precedes the development of an eating disorder — the restricted eating, bingeing, or purging functions as an anxiety-reduction mechanism. Food restriction creates a sense of control in a situation where anxiety feels overwhelming. Purging can temporarily reduce emotional distress. Ritualised eating behaviours reduce anxiety through predictability and routine.

In many cases, treating the underlying anxiety disorder produces significant improvements in eating disorder behaviour — because removing the anxiety driver reduces the 'need' for the eating disorder as a coping mechanism.

ARFID and Emetophobia

ARFID — Avoidant Restrictive Food Intake Disorder — involves restricted eating based on sensory characteristics of food, fear of choking or vomiting, or lack of interest in eating. In many cases, ARFID is directly driven by emetophobia: the fear of vomiting leads to avoidance of foods perceived as risky, and this avoidance progressively expands. Treating the emetophobia (as an anxiety disorder) typically resolves the ARFID food restriction.

Social Anxiety and Eating in Public

Social anxiety disorder frequently includes intense discomfort about eating in front of others — fear of being observed eating, of table manners being judged, or of being sick in a social eating context. This can cause significant social impairment and in some cases leads to restricted eating to avoid social eating situations.

Recovery Through Addressing the Anxiety Root

The Linden Method addresses the anxiety disorder that frequently underlies or co-presents with eating disorders. By reconditioning the sensitised alarm centre, the anxiety driver is eliminated — and many participants find that eating behaviours normalise significantly as part of their recovery from anxiety disorder.
