What is the cause of morning sickness?

A. Morning sickness is due to high levels of human placental lactogen
B. Morning sickness is due to high levels of human chorionic gonadotropin
C. Morning sickness is due to high levels of estrogen and progesterone

Answer 1

Morning sickness during pregnancy is caused by high levels of estrogen and progesterone.

Step-by-step explanation:

Morning sickness during pregnancy is caused by high levels of estrogen and progesterone. These hormones are secreted by the corpus luteum in the early stages of pregnancy and later by the placenta. The increased circulation of estrogen and progesterone is thought to trigger nausea and vomiting, which are common symptoms of morning sickness.
