Most of the effects of bulimia result from electrolyte imbalance and repeated purging behaviors. Loss of potassium due to vomiting, for example, damages the heart muscle, increasing the risk for cardiac arrest. Repeated vomiting also causes inflammation of the esophagus and possible erosion of tooth enamel, as well as damage to the salivary glands.
Some individuals with bulimia struggle also with addictions to drugs and alcohol, and compulsive stealing. Like those with anorexia, many people with bulimia may suffer from clinical depression, anxiety, obsessive-compulsive disorder, and other psychiatric illnesses.
