Small abdominal distension in early pregnancy is normal, but if it lasts for a long time, it is best to go to the hospital for a related examination. Small abdominal distension in early pregnancy may have the following causes: a. The uterus becomes larger and presses on the intestines and stomach causing abdominal distension. After women are pregnant, the baby in the uterus will gradually grow and develop from small to large, with the development of the baby, the uterus is gradually propped up, the propped up uterus naturally presses the gut, and the gut is squeezed, so that the food and gas in the gut can not be discharged normally, so the feeling of abdominal distension. This situation does not require treatment, is a natural physiological response. Second, the reduction in activity caused by constipation. In the early stage of pregnancy, women’s activity will suddenly decrease due to the fear of miscarriage. At the same time, after pregnancy, pregnant women may eat some high-protein and high-fat food, and the intake of vegetables and fruits may be very insufficient, resulting in less dietary fiber in the intestine and slower intestinal peristalsis, which will lead to constipation and cause the feeling of abdominal distension. Third, pre-miscarriage. Women’s bloating is a physiological phenomenon unique to pregnancy, sometimes it may be the result of uterine contractions, but sometimes it is also a precursor to miscarriage. Therefore, once the bloating occurs, should not be taken lightly, it is best to go to the hospital to do the relevant examination.
