The reasons for bloating in early pregnancy are as follows: a. Due to the increased level of progesterone in the body, progesterone inhibits smooth muscle movement to slow down intestinal peristalsis, resulting in bloating. Second, the uterus increases mechanical compression of the intestinal canal, which slows down intestinal peristalsis and produces abdominal distension. Third, in early pregnancy due to the emergence of pregnancy reaction, pregnant women are weak and do not like to exercise, resulting in the slowing of intestinal peristalsis. Abdominal distension is a common symptom of pregnancy, pregnant women do not need to be nervous, you can exercise to promote intestinal peristalsis, eat more food containing high dietary fiber, such as fresh vegetables, appropriate amount of fruit and coarse grains to laxative, promote intestinal peristalsis and reduce abdominal distension. With the increase of pregnancy weeks, the body hormones tend to stabilize, pregnant women bloating feeling will gradually reduce or disappear.
