Bulimia (or bulimia nervosa) is a serious mental illness. It can affect anyone of any age, gender, ethnicity or background. People with bulimia are caught in a cycle of eating large quantities of food (called bingeing), and then trying to compensate for that overeating by vomiting, taking laxatives or diuretics, fasting, or exercising excessively (called purging). Treatment at the earliest possible opportunity gives the best chance for a fast and sustained recovery from bulimia.
It’s normal for people who aren’t suffering from an eating disorder to choose to eat a bit more or “overindulge” sometimes. This shouldn’t be confused with a binge eating episode. Binge eating is often a way to cope with difficult emotions; someone may feel driven to binge eat if they’re feeling stressed, upset or angry, for example. During a binge, people with bulimia don’t feel in control of how much or how quickly they’re eating. Some people also say that they feel as though they’re disconnected from what they’re doing. The food eaten during a binge may include things the person would usually avoid. Episodes of binge eating are often very distressing, and people may feel trapped in the cycle of bingeing and purging. People with bulimia place strong emphasis on their weight and shape, and may see themselves as much larger than they are.
The binge/purge cycles associated with bulimia can dominate daily life and lead to difficulties in relationships and social situations. Bulimia can cause serious physical complications as well – frequent vomiting can cause problems with the teeth, and people may go to lengths to make themselves sick that could cause them harm. Laxative misuse can seriously affect the heart and digestive system. People with bulimia may also experience symptoms such as tiredness, feeling bloated, constipation, abdominal pain, irregular periods, or swelling of the hands and feet.
However, as sufferers are often a “normal” weight and often hide their illness from others, it can be very difficult to spot from the outside. Moreover, people with bulimia are often reluctant to seek help. As with other eating disorders, people around a person with bulimia will probably notice changes to their mood and feelings before seeing any physical change. They may also be preoccupied with and secretive around food, and feel self-conscious about eating around others. Low self-esteem, irritability and mood swings, and feelings of guilt, shame, and anxiety, especially after a binge, are also common.
If someone’s symptoms don’t exactly match all the criteria used to diagnose bulimia – for example, if the binge/purge cycles don’t happen as often as may be expected – they might be diagnosed with OSFED (other specified feeding or eating disorder). OSFED is as serious as any other eating disorder and it’s just as important that people suffering with it get treatment as quickly as possible.
There is no single cause of bulimia. While low self-esteem and concerns about weight and body image play key roles, there are many other contributing causes. Binge eating is triggered by both physiological factors (hunger) and emotional factors such as stress, depression or anxiety. Effective treatment for bulimia nervosa needs to target both the physiological and the emotional triggers as well as the underlying causes
