Farting in pregnancy may be related to dietary factors, hormonal changes and indigestion. 1. Dietary factors: During pregnancy, women like to eat food that can easily cause gas production, such as potatoes and sweet potatoes, which may lead to farting in pregnancy. 2. Hormonal changes: changes in estrogen and progesterone levels during pregnancy may lead to relaxation of the sphincter of the intestinal tract and paralysis of the smooth muscle, which in turn leads to a slowing down of peristalsis in the gastrointestinal tract, which can lead to increased gas production. 3. Indigestion: Women are prone to indigestion because they have less exercise during pregnancy. When food is stored in the gastrointestinal tract for a long time, gas is produced after fermentation, leading to farting during pregnancy. It is recommended to go to the obstetrics and gynecology department of the hospital for consultation, to clarify the cause of the problem under the guidance of a professional doctor, and to receive treatment for the cause of the problem.
