The records of 96 young women 25 years of age and less, who underwent cholecystectomy in the years 1977 to 1980 inclusive, were reviewed looking for correlations among obesity, parity, oral contraceptive usage and gallbladder disease. The main risk factor in this population was the presence, either past or present, of pregnancy. Oral contraceptive usage and obesity did not result in an increased risk of having gallbladder disease develop in this population. It is believed that this population is too young to demonstrate such an association. It was only when coupled with pregnancy that obesity or oral contraceptive usage resulted in an increased risk of having gallbladder disease develop.
