Serum leptin levels in women throughout pregnancy and the postpartum period and in women suffering spontaneous abortion

Abstract

Serum leptin concentrations rose slightly during pregnancy, fell following delivery and subsequently increased during the first six months postpartum. These variations were unrelated to changes in body composition, and may be responsible for the postpartum weight gain observed in some women. Abnormally low serum leptin levels were observed in women suffering spontaneous abortion in the first trimester of pregnancy.
