Definition & Terminology
Formal Definition
Etymology & Origins
The term "bulimia" comes from the Greek "bous" (ox) and "limos" (hunger), literally meaning "hunger of an ox." The term was historically used to describe extreme hunger, but was adopted in the 1970s to describe the binge-purge pattern now recognized as bulimia nervosa.
Anatomy & Body Systems
Medical Complications
Electrolyte Imbalance: Frequent vomiting and laxative abuse can cause dangerous electrolyte imbalances, particularly low potassium (hypokalemia), which can lead to heart rhythm problems and death.
Gastrointestinal System: Chronic vomiting can cause esophagitis, esophageal tears, stomach enlargement, constipation, and bowel dysfunction.
Dental Health: Stomach acid from vomiting erodes tooth enamel, causing cavities, sensitivity, and tooth loss.
Cardiovascular System: Electrolyte imbalances can cause dangerous heart rhythm abnormalities.
Kidney Function: Dehydration and electrolyte imbalances can impair kidney function.
Types & Classifications
Purging Type
The most common type, involving self-induced vomiting or misuse of laxatives, diuretics, or other medications.
Non-Purging Type
Inappropriate compensatory behaviors such as fasting or excessive exercise, without purging.
Severity Levels
Mild: 1-3 binge/purge episodes per week Moderate: 4-7 episodes per week Severe: 8-13 episodes per week Extreme: 14+ episodes per week
Causes & Root Factors
Primary Causes
Genetic Factors: Family and twin studies suggest genetic contributions to bulimia risk.
