Pregnancy and delivery is one of the main causes in the female body weight alteration, especially with obesity. This alteration in body weight has a significant effect not only for a femine beauty standpoint, but also for more important reproductive functions in postpartum. For the actual condition of the maternal body weight alteration and its clinical significance, we made the various analysis on the mast recent data available at our OB & GYN Dep. of Keio Univ. Hospital, and obtained the following results.
1. The average maternal weight gains by pregnancy is 11.71kg. Immediately after delivery, the maternal weight gains are on average 5.9kg compared with pre-gestational period 2. Maternal weight gains over 12kg (which are disadvantageous at delivery) have no significance in fetal growth.
3. 25% of puerpera maintains weight heavier than that of pre-gestational period for four months in postpartum. The group with obesity in postpartum shows the higher rate of anovulatory state compared with the group who recovers the normal body weight in postpartum.
4. Maternal weight alterations is mostly correlated with the cholesterol level change among serum lipids levels.
