Step-by-step explanation:
Bulimia nervosa is an eating disorder in which people recurrently binge on large amounts of food, followed by purging the food from the body through vomiting, using laxatives, exercising excessively, or other methods. This eating cycle involves consuming a large amount of food in a short period of time, often feeling a lack of control during the binge, and then attempting to rid the body of the consumed food. These purging behaviors can have serious health consequences and can lead to electrolyte imbalances and irregular heartbeat.
