Blood Donation decreases the risk of type 2 diabetes and cardiovascular disease
Epidemiologists have observed that blood donation is associated with decreased risk of type 2 Diabetes and Cardiovascular disease. The relationship between iron stores and insulin sensitivity was investigated, after controlling for known confounding
factors, and compared insulin sensitivity between blood donors and individuals who had never donated blood (nondonors). The results stated that frequent blood donors had increased insulin sensitivity, decreased insulin secretion and significantly lower iron stores than nondonor but there was no difference in their blood hematocrits and blood hemoglobin concentrations. The decreased iron stores have proved to be a protective factor for the development of Diabetes Mellitus. In fact, the higher the ferritin concentrations, the higher the incidence of type 2 Diabetes Mellitus, according to epidemiologic studies.
