According to a 2024 study, up to 32% of individuals with an eating disorder display abnormal electrolyte levels, which are linked to a higher mortality risk. Anorexia nervosa, a complex eating disorder, can cause dangerous shifts in crucial minerals, including potassium, sodium, and phosphate, impacting major bodily functions.

Lanugo, the fine, downy hair that can appear on the body, is a common symptom of anorexia nervosa, indicating extreme malnutrition and weight loss. It is the body's attempt to regulate temperature when there is insufficient body fat to provide insulation.

In a large study involving 374 severely malnourished anorexia nervosa inpatients, an overwhelming 92.8% were found to have at least one micronutrient deficiency at hospital admission. These significant nutritional deficits, far beyond simple calorie deprivation, highlight complex health issues requiring specialized medical attention during nutritional rehabilitation.

According to a 2025 review, the global prevalence of anemia in patients with anorexia nervosa is approximately 44.8%, but are anorexic people iron deficient? While direct nutritional deprivation is a factor, the underlying causes are more complex and extend beyond simple lack of iron intake.
