Causes Of Morning Sickness

Morning sickness makes pregnant women feel unwell and sick. It is really a sign of pregnancy. It is a sign of pregnancy because, the levels of pregnancy hormones, human chorionic gonadotrophin (hCG) and estrogen gets elevated in pregnancy. These hormones are produced by the placenta that nourishes and develops the fetus. High levels of hCG trigger nausea and vomiting. Morning sickness is higher when the embryo implants into the uterus and it increases two times more in every two days. The higher the levels of hCG in the body increase the intensity of morning sickness. Its intensity is more in women who have twins or multiple fetuses in their pregnancy.
