Coagulation defects associated with jejunoileal bypass and term pregnancy.

A case is presented in which pregnancy occurred after jejunoileal bypass for treatment of obesity. The pregnancy was complicated by coagulation defects apparently on the basis of liver damage secondary to the bypass. Pertinent literature is reviewed, and the conclusion is reached that although the majority of patients becoming pregnant after jejunoileal bypass tolerated pregnancy well, hepatic disease may occur as it does in nonpregnant individuals.
