Bulimia Treatment
If you have found this page, you may be worried about your own eating, or frightened for someone you love. Perhaps you have noticed a pattern of bingeing followed by making yourself sick, using laxatives, fasting, or over-exercising to undo it. Perhaps the secrecy and shame have become exhausting. Bulimia nervosa is a serious but treatable mental health condition, and recognising it is the first step towards getting help.

You do not need to be underweight, or to have been struggling for years, before you deserve support. This page explains what bulimia is, the signs to look for, the genuine health risks involved, and the evidence-based treatments that help people recover. It also explains when bulimia becomes a medical emergency, and how to get assessed at Promis.
What is bulimia nervosa?
Bulimia nervosa is an eating disorder defined by a cycle of binge eating followed by behaviour intended to compensate for it. During a binge, a person eats a large amount of food in a short time and feels a loss of control. This is usually followed by purging, which may mean making yourself vomit, or using laxatives, diuretics, fasting, or excessive exercise to try to prevent weight gain.
People with bulimia often place a great deal of importance on their weight and body shape, and judge themselves harshly because of it. Unlike anorexia, many people with bulimia are a normal weight or above, which is one reason the condition can stay hidden for a long time. As the NHS notes, the cycle is often driven by intense distress and is very difficult to break alone, which is exactly why professional treatment works.
Bulimia frequently occurs alongside depression, anxiety, trauma, self-harm, alcohol use, or drug use. At Promis, eating disorders are understood and treated as part of a wider mental health and addiction model, rather than in isolation.
Types We Treat
Bulimia Nervosa is primarily categorised into two types based on the methods used to compensate for binge eating. Understanding these types is crucial for identifying the specific behaviours and for appropriate treatment recommendations.
Signs & Symptoms
Psychological
The psychological signs of bulimia are often the hardest to see from the outside. They commonly include:
- Being preoccupied with weight, body shape, and food, and fearing weight gain
- Mood changes, low self-esteem, anxiety, or feeling out of control
- Judging yourself harshly because of your weight or shape
- A great deal of shame and secrecy around eating
Only a qualified professional can diagnose bulimia, and you do not need to tick every box to need help. If these patterns feel familiar, a Promis assessment is a confidential way to understand what is happening and what would help.
Physical
According to the NHS, physical signs that may point to bulimia include:
- A sore throat, or swelling around the jaw and cheeks
- Tooth damage from repeated vomiting
- Calluses on the knuckles
- Irregular periods
- Tiredness and bloating
Because weight may appear unchanged, these physical clues can be easy to miss. Repeated purging can also disturb the body's chemistry in dangerous ways, which is covered in the safety section below.
Behavioural
The behavioural pattern is the core of bulimia. According to the NHS, common behavioural signs include:
- Eating very large amounts of food in one go, often secretly, with a sense of loss of control
- Making yourself sick, or using laxatives, diuretics, fasting, or excessive exercise after eating
- Strict dieting between binges, or skipping meals
- Going to the bathroom soon after meals
When to Seek Specialist Help
Bulimia is not only a psychological condition. Repeated purging can disturb the body's chemistry in ways that are dangerous and sometimes life-threatening, even when weight looks normal. The Royal College of Psychiatrists guidance on Medical Emergencies in Eating Disorders (MEED) exists because these risks are serious and easy to underestimate.
Seek urgent medical help if you or someone you are worried about has any of the following:
- Fainting, dizziness, palpitations, or chest pain
- Muscle weakness, severe cramps, or seizures (possible signs of electrolyte disturbance)
- Blood in vomit, or vomiting that will not stop
- Confusion, extreme exhaustion, or difficulty staying awake
- Thoughts of suicide, or urges to harm yourself
What to do:
- For a same-day medical concern, contact your GP and ask for an urgent appointment, or call NHS 111.
- If someone has collapsed, is having a seizure, has chest pain, or you believe their life is at risk, call 999 or go to A&E.
- Electrolyte imbalances caused by purging can affect the heart and may need urgent blood tests and treatment. Do not wait to see if symptoms pass.
If you are struggling with suicidal thoughts, you can call the Samaritans free at any time on 116 123. For eating disorder support and signposting, the Beat helpline can help you understand your options. Promis is a voluntary clinic and not an emergency service, so if there is immediate danger, please use 999, A&E, or 111 first.
How We Treat at PROMIS
Bulimia is treatable, and most people can recover with the right support. Treatment focuses on interrupting the binge and purge cycle, addressing the thoughts and feelings that drive it, and rebuilding a steadier relationship with food, body, and emotion.
NICE guideline NG69 (Eating disorders: recognition and treatment) sets out the evidence-based approach:
- For adults, the first-line treatment is a guided self-help programme based on cognitive behavioural therapy, or an eating-disorder-focused course of cognitive behavioural therapy known as CBT-ED. CBT-ED helps people understand and change the patterns of thinking and behaviour that keep bulimia going.
- For children and young people, NICE recommends family-based treatment for bulimia nervosa, known as FBT-BN, which involves the family in supporting recovery.
Treatment may also address co-occurring difficulties such as depression, anxiety, trauma, self-harm, or substance use, because these often interact with the eating disorder. Some people benefit from psychiatric input where mood, risk, or medication need review. The aim is not simply to stop the behaviour, but to understand and treat what drives it.
How Promis can help
Promis is a mental health and addiction clinic that treats eating disorders, including bulimia, as part of its wider model of care. Treatment is assessment-led: we start by understanding the full picture, including the eating disorder itself, any co-occurring depression, anxiety, trauma, or substance use, and your physical health and risk. You can read more about our approach on our eating disorders page, and the first step is always a confidential assessment.
Some honest framing matters here. Promis is a voluntary clinic, not an acute or emergency unit. We provide weekly psychiatric input rather than round-the-clock psychiatric cover, and where someone needs acute psychiatric admission we work with our partner clinic, Cardinal Clinic in Windsor. Our inpatient care is delivered at two small clinics, Hay Farm in Kent and Kendrick Mews in London, with outpatient and day care also available. Structured treatment is often delivered through primary care and shaped around each person's needs.
Treatment combines eating-disorder-focused psychological therapy with work on the emotional drivers underneath, drawing on the same evidence base NICE recommends. Because bulimia so often sits alongside other difficulties, treating it within an integrated mental health and addiction model means these are not left untreated.
If you are unsure whether your situation warrants help, it does. You can contact us confidentially to talk through your options with no obligation.
Treatment Formats
Residential
Inpatient or residential treatment may be appropriate when the eating disorder is severe, when there is significant medical risk, when co-occurring addiction or self-harm makes home treatment unsafe, or when a protected setting is needed to interrupt an entrenched cycle. Promis offers inpatient care at two small clinics, Hay Farm in Kent and Kendrick Mews in London, alongside outpatient and day care. An assessment is how the right starting point is decided.
Day Patient
Day-patient or intensive day care offers more structure, including support around mealtimes, while you continue to live at home. It can suit people who need more containment than weekly therapy provides but do not require an overnight admission. It is reasonable to step up to this level if outpatient treatment is not enough, and to step down again as things stabilise.
Outpatient
This suits most people with bulimia. You live at home and attend regular sessions, usually CBT-ED for adults or FBT for younger people. It works well when you are medically stable and have enough support to practise change between sessions. NICE NG69 supports matching the intensity of treatment to clinical need rather than applying one approach to everyone.
