Why do your fingers turn blue when your anorexic?

Fingers may turn blue in individuals with anorexia due to poor circulation and reduced blood flow, which can be a result of malnutrition and low body weight. Anorexia can lead to a decrease in body temperature and peripheral vasoconstriction, causing the extremities to appear bluish. Additionally, electrolyte imbalances and other complications from the condition can further exacerbate circulation issues. It’s essential for individuals experiencing these symptoms to seek medical help.
