Document Summary
Increased prevalence of: cardiovascular disease, diabetes, hypertension, stroke, gallbladder disease, respiratory disease, muscular skeletal problems, hormone-related cancers. Bulimia nervosa: one of the most common psychological disorders on college campuses. Eating a larger amount of food (typically junk food) than most people would eat under similar circumstances. Individual attempts to compensate for binge eating and potential weight gain: self-induced vomiting, reduces approx. 50% of calories just consumed; less if it is delayed: using laxatives and diuretics, little effect, excessive exercise, fasting between binges, over-concern with body shape, most patients are within 10% of normal weight. Salivary gland enlargement caused by repeated vomiting: gives face a chubby appearance, dental enamel erosion. Electrolyte imbalance: imbalance of bodily fluids, including sodium and potassium. If untreated, can cause cardiac arrhythmia, seizures, and renal (kidney) failure: calluses on fingers or hands from sticking fingers down throat. Young women with bulimia develop more body far than age- and weight-matched healthy controls.
