Bulimia Nervosa - What Happens
Bulimia can develop after a person has followed a very restrictive diet. Binging may also be triggered by a stressful event, when food gives you a sense of comfort. Feeling guilty and ashamed of binging can cause you to purge to avoid weight gain. This starts the cycle of binging and purging that becomes a habit.
As bulimia develops, you may not eat at the beginning of the day, but later you may binge to comfort yourself, especially at the end of a stressful day.
Vomiting causes the body to release endorphins-natural chemicals that make you feel good.1 Eventually you may make yourself vomit even if you have not overeaten so that you can feel good. Soon, you lose control over the binge-purge cycle. Repeated vomiting, fasting, exercising too much, or misusing laxatives, diuretics, ipecac syrup, or enemas will eventually cause serious, long-term health problems.
After bulimia becomes a pattern, it is very difficult to return to normal eating without help. Unhealthy eating behaviors can continue for many years before a person seeks treatment.
If not treated, bulimia can lead to serious, long-term health problems. It is common for people to hide the condition from others for years. By the time others discover the disorder, many people with bulimia already have serious problems. These range from mild to severe, depending on the type of purging behaviors and how long they have continued.5 Health problems caused by bulimia include:
- Tooth decay, toothaches, swollen gums, gum disease (gingivitis), and erosion of tooth enamel. These are caused by acid in the mouth from vomiting.
- Osteoporosis.
- Electrolyte imbalances and changes in metabolism that can lead to heart problems, such as arrhythmia and even death.
- Dehydration, which can lead to weakness, fainting, or kidney damage.
- Inflammation or tears of the esophagus, which may cause bloody vomit.
- Swollen salivary glands.
- Fainting or loss of consciousness, usually because of low blood pressure.
- Abnormal heartbeat (arrhythmia).
- Low body temperature.
- Suicide risk when feeling discouraged about having bulimia or a relapse or about ongoing body image issues.
- Long-term problems with bowel movements because of laxative abuse.
Overuse of medicine (such as ipecac syrup) to cause vomiting can lead to diarrhea, weakness, low blood pressure, chest pain, and difficulty breathing. A person can die from prolonged overuse of these medicines.
Other mental health problems often occur along with bulimia, which may make treatment take longer or make bulimia more difficult to treat.4 These conditions include:
- Depression, which commonly occurs with eating disorders and increases related feelings of guilt, anxiety, and obsession.
- Substance abuse, which occurs in around one-fourth of those with bulimia.
- Borderline personality disorder, which more commonly occurs with bulimia than with other eating disorders.
- Anxiety and anxiety disorders.
- Obsessive-compulsive disorder.
- Social anxiety disorder or other phobias.
- Panic disorder or panic attacks.

When you're feeling low, a dish of ice cream can sure perk things up. But for some, eating to soothe emotions is a crutch.
