Eating disorders and POTS are not rare bedfellows. The overlap is well-documented and clinically complex. Some of the overlap is shared physiology — low blood volume in POTS is worsened by restricted intake; some POTS medications affect appetite. Some is environmental — POTS is more common in young women, who are also the population most at risk of restrictive eating disorders. Some is iatrogenic — eating patterns that started as careful management of post-prandial autonomic load can slip into restriction over time. The two pictures interact, and treating one without the other often does not work.
Eating disorder care in this pathway is the structured work of addressing the eating-disorder picture in someone whose body also has dysautonomia. The dietitian, the psychological work, and the medical management all sit inside the same plan. Refeeding pacing accounts for autonomic and cardiovascular tolerance. Medication choices consider the cardiac picture. Therapy uses approaches — CBT-E, family-based treatment where appropriate, dialectical-behaviour-informed work, exposure-based work — that fit the person rather than a generic protocol.
This service is for adults in the dysautonomia pathway with a diagnosed or clinically apparent eating disorder co-occurring with POTS or autonomic dysfunction — anorexia nervosa, bulimia nervosa, atypical presentations, or significant restriction that is destabilising the autonomic picture. It is not the right starting point where there is acute medical risk requiring inpatient eating-disorder care; in those cases, hospital-based eating-disorder services are the responsible first step.
The first appointment reads both pictures carefully. The eating-disorder presentation — what is being eaten and what is not, weight history, restrictive or compensatory behaviours, broader mental-health picture, prior treatment. The autonomic picture — standing data, medication, blood volume, current symptoms. Both are mapped before treatment is built.
Where the medical risk profile calls for inpatient or higher-level care, that is named clearly and the referral made. Where outpatient work is appropriate, the structure of that work is set up.
The plan is built across the team — credentialed eating-disorder clinician for the structured psychological work, dietitian for refeeding and nutritional structure, autonomic clinician for the dysautonomia management. The aim is for the eating-disorder work and the autonomic work to support each other rather than compete.
CBT-E or other evidence-supported eating-disorder approaches are used, modified for the autonomic and POTS context. Where dialectical-behaviour-informed work, family-based work or exposure-based work is the right addition, that is integrated.
The work is held inside the biio. record so the broader team — medical, OT, psychology, exercise physiology — can see what is happening and coordinate. Where the GP, psychiatrist or specialist eating-disorder services are part of the broader picture, communication runs through the same record.
Eating-disorder recovery in a dysautonomic body is rarely short. The work continues through stages — stabilisation, weight restoration where appropriate, behaviour change, relapse-prevention — and the autonomic picture is reviewed alongside at each stage.
When the eating-disorder work is going well, the eating-disorder picture begins to ease without the autonomic picture being destabilised. Restrictive behaviours reduce. Weight and nutritional adequacy stabilise where that is the goal. Standing tolerance improves as blood volume comes back. Quality of life moves on both fronts together rather than one at the cost of the other.
Eating disorder care does not, by itself, treat dysautonomia, and dysautonomia care does not treat an eating disorder. Each has its own drivers and its own course. What integrated care can do is read them together, so the work on one does not undo the work on the other — and in a presentation where each has often been treated in isolation with poor results, that often matters more than the patient or the team had reason to expect.
