Whether bloating will affect the fetus depends on the condition and cause of the bloating. If the bloating is mild and has no effect on the diet of the pregnant woman or her bowel movements, it generally will not affect the fetus. However, if the bloating is more obvious and accompanied by constipation, pain and other discomforts, it may affect the fetus, leading to contractions, miscarriage, premature labor and so on. It is necessary to go to the hospital in time for relevant treatment and avoid taking medicines privately and blindly in order to prevent any effect on the fetus. In addition, pregnant women during bloating need to adjust the diet structure, avoid eating some easy to produce gas food, such as soy products, sweet potatoes, radish, etc., you can drink some yogurt to promote gastrointestinal peristalsis, help food digestion and gas discharge, to alleviate bloating. Generally speaking, the problem is not big.
