Does high hormones and Progesterone can cause the nausea that most women experience as morning sickness?

Yes, high hormone levels, particularly progesterone, can contribute to nausea and morning sickness in pregnant women. Progesterone relaxes smooth muscles, including those in the gastrointestinal tract, which can slow digestion and lead to feelings of nausea. Additionally, other hormonal changes, such as increased levels of human chorionic gonadotropin (hCG), may also play a role in morning sickness. Together, these hormonal fluctuations can significantly affect a woman's digestive system during early pregnancy.
