Questions in The Maternal and Child Health Forum are being answered by medical professionals from Henry Ford Health System , consistently ranked one of the best hospitals in America. I've had two pregnancies, and was hospitalized each time for hyperemesis gravidarum. Complete bed rest helped, as did having relatives come help out for a couple of months.

Morning sickness is a very common problem during early pregnancy.
This is the easy situation. More significant nausea in early pregnancy occurs at any time of the day, but the etiology, slow digestion due to the increased progesterone levels of pregnancy that quiet the digestive tract musclar movement, seems an important contribution. The reason for this sensitivity to smells in pregnancy is unclear. This concept is still alive, but has fewer followers than a generation ago. Current anti-nauseant drugs offer an improved quality of life.
