Overview
Bulimia nervosa is a serious eating disorder characterized by cycles of binge eating followed by compensatory behaviors like purging to prevent weight gain. It involves an unhealthy preoccupation with body shape and weight that can lead to significant physical complications.
Understand this condition
The body is subjected to a cycle of extreme calorie intake followed by physical stress from purging. This disrupts chemical balances, especially electrolytes like potassium, which are vital for heart function. Over time, stomach acid damages the esophagus and teeth while the digestive system struggles to process food normally.
Why it happens
Biological factors like serotonin imbalances may trigger cravings and affect mood regulation. The disorder often progresses as a coping mechanism for emotional distress, where the binge-purge cycle provides temporary relief from anxiety. Over time, this behavior becomes a compulsive habit that is difficult to break without professional intervention.
