Gall bladder disease and ABO blood group.

Because it had been shown that an elevated total serum cholesterol was associated with phenotype A in many western European and Japanese populations as compared to non-A phenotype, a study was conducted to see whether there was any correlation between ABO blood group and gall bladder disease in our environment. No correlation was found between ABO blood group and gall bladder disease. However, the incidence of gall bladder disease was much higher in females than in males and the incidence was found to be highest in the fourth and fifth decades of life.
