Anorexia (or anorexia nervosa) is a serious mental illness that can cause individuals to limit how much they eat or drink. They may develop “rules” around what they feel they can and cannot eat, as well as things like when and where they’ll eat. Anorexia can affect anyone of any age, gender, ethnicity or background. In some cases, anorexia nervosa can be characterized by low body weight, however you can never tell how unwell someone is by just considering their weight.
As well as limiting how much they eat, they may do lots of exercise, make themselves sick, or misuse laxatives to get rid of food eaten. Some people with anorexia may experience cycles of bingeing (eating large amounts of food at once) and then purging.

Weight and shape may be a big factor in someone with anorexia’s sense of self-worth. This can lead to them checking their body regularly and weighing themselves or avoiding scales and mirrors. People with anorexia may have a distorted image of themselves, meaning that they seem themselves as bigger than they really are. This is known as ‘body dysmorphia’. They may also experience a deep fear of gaining weight.
Sometimes, someone’s symptoms may not exactly match everything a doctor checks for to diagnose anorexia – for example, they may be a weight considered “normal” for their age, sex, and expected development. Depending on the exact symptoms, they might be diagnosed with another form of other specified feeding or eating disorder (OSFED). This is just as serious and can develop both into or from anorexia. It’s just as important that people suffering with OSFED get treatment as quickly as possible.
I thought about food and calories all the time. I tried to avoid certain foods and only had ‘safe’ foods which I felt were okay to eat.
Anorexia can cause severe physical problems because of the effects of starvation on the body. It can lead to loss of muscle strength and reduced bone strength. People whose periods have previously started may find that they stop which is known as ‘amenorrhoea’. They may also find that their sex drive decreases.
The illness can affect people’s relationship with family and friends, causing them to withdraw; it can also have an impact on their work or education. As with other eating disorders, anorexia can be associated with depression, low self-esteem, anxiety, and other complications or comorbidities. The seriousness of the physical and emotional consequences of the condition may not always be acknowledged or recognised, and those with anorexia may find it difficult to seek help – they may go to great length to hide their behaviour from family and friends, or sometimes might not realise that they’re ill.
Anorexia in children and young people is similar to that in adults in terms of its psychological characteristics. But children and young people might, in addition to being of low weight, also be smaller in stature than other people their age, and slower to develop physically.
There are a number of signs of anorexia, but someone doesn’t have to have all of them to be suffering. It’s not always obvious that someone has an eating disorder – remember, they are mental illnesses. If you’re at all worried about yourself or someone else, even if only some of the signs on this page are present, it’s always best to seek help as quickly as possible, as this gives the greatest chance of a full recovery. The first step is usually to make an appointment with the GP.
I was pretty desperate and hopeless. It took a long time but I eventually entered recovery and have never looked back.
If someone is developing anorexia, often changes in behaviour are noticeable before changes to physical appearance. Signs include:
