Why do anorexics have low hematocrit?

Anorexics often have low hematocrit levels due to insufficient nutritional intake, which can lead to anemia. A lack of essential nutrients, particularly iron, vitamin B12, and folate, impairs red blood cell production and function. Additionally, dehydration, which can occur in individuals with anorexia, may falsely elevate hematocrit levels initially, but overall, the body’s inability to maintain proper blood volume and red blood cell count results in lower hematocrit. This combination of factors contributes to the observed low hematocrit levels in individuals with anorexia.
