Final answer:
To avoid weight gain after bingeing, individuals with bulimia nervosa commonly induce vomiting or use laxatives, along with other compensatory behaviors such as excessive exercise. Bulimia can lead to severe health and psychological issues, and professional treatment is vital.
Step-by-step explanation:
People who have bulimia nervosa typically avoid gaining weight after bingeing on food by engaging in compensatory behaviors such as inducing vomiting or using laxatives. These attempts to 'purge' the food aim to minimize calorie absorption following a binge eating episode. Additionally, individuals may resort to other methods like excessive exercise or the use of enemas or diuretics. It is important to note that bulimia nervosa can lead to serious health complications, including electrolyte imbalances, irregular heartbeat, and both dental and digestive issues.
While people with bulimia may maintain a normal weight, health problems caused by their behaviors can be life-threatening. This eating disorder is also often associated with psychological issues such as anxiety and depression, and there is an increased risk for substance abuse. It's critical for those suffering from bulimia nervosa to seek professional medical help.
