Final answer:
Bulimia nervosa is the eating disorder where individuals binge on food and then engage in purging behaviors. It can lead to significant health and psychological problems, despite sufferers often appearing to be of normal weight.
Step-by-step explanation:
The eating disorder characterized by consuming large quantities of food and then purging through vomiting, laxative and diuretic use, and/or excessive physical exercise is known as bulimia nervosa.
This condition involves episodes of binge eating followed by compensatory behaviors to prevent weight gain. Sufferers of bulimia nervosa often maintain a normal weight range, but they may face serious health issues, such as electrolyte imbalances, irregular heartbeat, kidney failure, and tooth decay.
Additionally, individuals with bulimia often experience psychological issues like anxiety, depression, and an increased risk for substance abuse.
