Eating Disorders and GLP-1 Medications: A Critical Warning

Many people who are struggling with their weight will have 'disordered eating', unhealthy patterns that cause distress but don't meet the clinical threshold for a diagnosis of an eating disorder. Think of it as a continuum: normal eating with occasional emotional eating, then disordered eating such as stress bingeing, rigid food rules, or chronic dieting, and finally clinical eating disorders, which are serious mental illnesses with the highest mortality rate of any psychiatric condition.

Binge Eating Disorder involves recurring episodes of eating large amounts rapidly, feeling out of control, and experiencing significant shame and distress afterward. Unlike occasional overeating, these binges happen regularly and severely impact daily life. Bulimia Nervosa combines binge eating with compensatory behaviours like making yourself sick, abusing laxatives, or exercising excessively. Anorexia Nervosa involves severe food restriction, an intense fear of weight gain, and distorted body image. It has the highest death rate of any mental illness.

The evidence on GLP-1 medications varies dramatically by condition. For Binge Eating Disorder, studies show promise. GLP-1 medications significantly reduce binge episodes and food obsessions. Patients report the medications quieten the biological drivers of bingeing, creating mental space for psychological work. For Bulimia Nervosa, evidence is limited and concerning. There's serious risk that appetite suppression could trigger severe restriction between binges. For Anorexia Nervosa, these medications are genuinely dangerous.

We have been hugely concerned to hear about people with active anorexia who are already underweight getting access to these medications from careless or unscrupulous online providers. Both of us have had patients who are underweight and yet managed to get hold of these medications to make restricting their intake easier. Clearly, if someone is underweight then this medication is not suitable and can have disastrous and deadly results.

People with high drive for thinness, whether diagnosed with an eating disorder or not, are obtaining these medications through deception. Some online prescription models make this frighteningly easy: falsified photos, borrowed images, lies about weight and health conditions that go unchallenged or investigated. When being thin matters more than being healthy, any weight loss tool seems justified.

In our clinical experience, GLP-1 medications cause serious harm when eating disorders or high drive for thinness are present. These drugs work by suppressing appetite and slowing digestion, effects that can be therapeutic for obesity but become weapons in the hands of someone with disordered eating. Appetite suppression makes dangerous food restriction easier. Reduced hunger hides the body's desperate nutritional needs. Weight loss 'success' can intensify disordered thinking.

If you have any eating disorder, history of one, or recognise a high drive for thinness in yourself, you must discuss this honestly with your prescribing doctor. Your life is too valuable to risk on medications that could worsen a mental illness. Recovery is possible, but it requires the right treatment. For those with Binge Eating Disorder who are working with appropriate clinical support, however, these medications may offer genuine hope, providing the breathing space needed to address the psychological roots of bingeing.
