In brief: Increased estrogen
It is felt to be caused by an increase in circulating estrogen during pregnancy.
Morning sickness can actually occur at any time of the day. It usually resolves by week 12.

In brief: Thyroid
We are not entirely sure but there is some evidence to suggest it is because of transient overactivity of the thyroid.
It probably is a primitive protective mechanism to prevent exposure to spoiled or rotten food.

In brief: Progesterone
Its from increasing levels of Progesterone mostly.
Progesterone is known to relax smooth muscle in the stomach and esophagus, and cause nausea and heartburn. Just ask anyone who has taken the morning after pill.
