Classified as an eating disorder, bulimia can be much more difficult to spot than anorexia. People with bulimia are usually of average or slightly above average weight and the signs aren't always clear. Chronic bingeing and purging leads to many health problems-some of which are life-threatening. For many, the side effects of bulimia - while dangerous - are mostly unseen. The teeth and mouth are often affected, though others might not notice. Frequent vomiting brings up stomach acid into the mouth, eroding teeth enamel. Cavities and gum infections are common in people with bulimia. The stomach acid also irritates the esophagus, producing heartburn, and the salivary glands, making them swell.

Other common medical complications and adverse bulimia effects include internal physical damage, such as chronic irregular bowel movements due to abusing laxatives. The most dangerous side effect of bulimia is dehydration due to purging. Vomiting, laxatives, and diuretics can cause electrolyte imbalances in the body, most commonly in the form of low potassium levels. Low potassium levels trigger a wide range of symptoms ranging from lethargy and cloudy thinking to irregular heartbeat and death. Chronically-low levels of potassium can also result in kidney failure.

The emotional side effects of bulimia may include:

• Overwhelming sense of isolation
• Feelings of shame and guilt
• Depression symptoms
• Low self-esteem.

Because bulimia is the result of a variety of psychological, cultural, familial and biological causes, curing it is rarely simple. It requires professional assistance to treat effectively. Ten percent of people with bulimia eventually die from its effects, usually from the electrolyte imbalance caused by dehydration.
