On average, studies suggest a potential loss of approximately 15 to 25 years of life for individuals diagnosed with anorexia.
Nutrient deficiencies and muscle breakdown
Another serious side effect of undereating is the development of nutrient deficiencies, which can lead to health conditions like anemia (often a result of iron deficiency), cold intolerance, hair loss, skin problems, insomnia, bone issues, and a weakened immune system.
