What Causes Pain Around the Belly During the Second Trimester of Pregnancy?
First, it belongs to physiological reasons, which are closely related to the gradual development of the fetus and the enlargement of the uterus during the second trimester of pregnancy. At this time, the uterine ligaments will be excessively stretched, causing pain. Of course, some reasons are pathological, such as signs of miscarriage, cysts or inflammation of the ovaries or uterus, etc.
1. Physiological abdominal pain: When pregnant women reach the fourth or fifth month, their bellies will suddenly become larger and the uterus will enlarge. At the same time, the round ligament of the uterus will be stretched, causing many expectant mothers to feel some abdominal pain. This pain is usually located on one or both sides of the lower abdominal uterus, manifesting as radiating pain, dull pain, or dull pain. When walking long distances or changing positions, the pain will become more obvious. In addition, excessive exertion during sexual intercourse during the second trimester can also cause abdominal pain for pregnant women.
2. Pathological abdominal pain:
1) Threatened miscarriage: refers to a small amount of vaginal bleeding, followed by paroxysmal lower abdominal pain or back pain before 28 weeks of pregnancy.
2) Ovarian cyst torsion: During the early, late, or early second trimester of pregnancy, as the uterus and its affiliated organs enter the abdominal cavity, it is more prone to cyst torsion. This causes pregnant women to experience intermittent pain in one side of the lower abdomen.
3) Severe uterine torsion: If pregnant women have uterine fibroids, congenital deformities, or ovarian tumors during pregnancy, it can cause uterine torsion exceeding 90 degrees, which may lead to acute abdominal pain.
4) Hiatal hernia and reflux esophagitis.
