How does bulimia nervosa affect the body?

Bulimia nervosa has profound effects on both mental and physical health, with significant impacts on the digestive system and major organs. This eating disorder is characterized by episodes of binge eating followed by purging behaviors, such as vomiting, excessive exercise, or fasting. Such actions can lead to serious health complications.

For instance, frequent vomiting can cause severe dental erosion due to stomach acid coming into contact with teeth, potential esophageal damage, and electrolyte imbalances, which can cause heart rhythm abnormalities. The digestive system is directly affected, as the body struggles to process food properly. Additionally, repeated cycles of bingeing and purging can lead to gastrointestinal issues such as delayed gastric emptying or chronic acid reflux.

These physiological consequences highlight the body-wide impact of bulimia nervosa, underscoring that it does not merely affect mental health or result in weight gain or improved metabolic health. Rather, it poses serious risks that can compromise the functionality of major organs and overall bodily health. This comprehensive view of bulimia nervosa emphasizes the critical need for intervention and treatment that addresses both psychological and physical health aspects.
