Written by healthwords.ai's team of doctors and pharmacists based in UK | Updated: 24 Jan 2023 | 4 min read

Bulimia, also known by its longer medical name of bulimia nervosa, is a mental health condition and type of eating disorder. It can have a huge impact on people's day-to-day lives and can lead to further health problems which in severe cases can be life-threatening if not treated.

Symptoms and the severity of symptoms can vary from person to person but bulimia is characterised by cycles of eating or binging on large amounts of food in a short space of time and then compensating for this by restricting food, inducing vomiting, using laxatives, or excessively exercising.

The compensatory behaviours to try and avoid weight gain cause hunger and so can lead to binge eating and is why bulimia can be a vicious cycle of binging followed by purging or restricting. Along with this, poor body image specifically regarding weight is also a common factor.

More information

Bulimia can drive feelings of guilt or anxiety around food which can affect someone's day to day mental wellbeing. It can also trigger other mental health problems such as depression, social withdrawal and self-harm. Signs of bulimia can be hard to spot as people can sometimes try to hide their symptoms.

Other than the signs mentioned already, disappearing after eating, mood changes, missing meals, fear of putting on weight, and feeling out of control around food, could all be signs of an eating disorder. People can also develop teeth problems or sores on their knuckles from inducing vomiting.

Bulimia can cause other physical symptoms of dry skin, bloating or swelling, stomach pain, constipation, dizziness, or fainting. If left untreated bulimia can lead to health problems such as anaemia and a lowered immune system. Heart problems or other organ problems are a risk, due to electrolyte imbalances from the induced vomiting which can be life-threatening (electrolytes are types of salts in your body that are needed within specific ranges for your body to function).

Who suffers from it?

Bulimia can start at any age and in any gender. It's more common in teenage girls although the amount of males suffering from bulimia is increasing. There is no exact cause for bulimia however it is thought to be a combination of genetic, societal and psychological factors meaning it is neither nature nor nurture but a combination of these together.

You are at a higher risk of developing bulimia if you live in a Western society, if a family member suffers from an eating disorder or is a frequent dieter, if you have low self-esteem or have had negative comments about your body weight or shape growing up, if you have suffered childhood trauma or if you started your periods at a young age.

There's an increased risk of developing an eating disorder if you are a competitive athlete in sports that have an emphasis on body shape or weight, such as dancing or gymnastics.

How is it treated?

Many people do not seek treatment for bulimia however it is important to seek help and support as soon as you feel able to as early intervention can improve recovery and give you a better quality of life. Treatment for bulimia is three-fold, it is about breaking the binge and restrict or purge cycle through eating regular meals and also supporting and treating the psychological side around the challenge and fears of eating regularly and any factors that may have led to the bulimia starting.

Finally, it is about making sure your physical health is ok (such are your heart and your vitamin and mineral levels).

Help can come in the form of talking therapies such as CBT (cognitive behavioural therapy) which can be online or in-person with a trained therapist, family therapy (for people under 18), and help from a nutritionist. Your doctor can help organise the support and also make sure that your physical health is ok.
