Follow the page from the 3.9% lifetime mortality and suicide risk to the hidden medical ripple effects like osteoporosis up to 2.3 times higher and a 5 fold rise in esophageal cancer for chronic vomiters.

Bulimia nervosa is often described as an eating disorder, but the statistics reach far beyond weight, touching mortality, bone health, and the risk of cancer. Even with treatment, relapse is common, with about 50% of patients relapsing within a year, and long term follow up still leaving many with residual symptoms. You will also see how the disorder reshapes everyday outcomes, from unemployment and fertility to electrolyte related seizures and the pattern of comorbid depression.
