Pregnancy stomach pains like menstruation are considered for two reasons, one is physiological and the other is pathological. If the pain is light and less frequent it may be a physiological phenomenon, but if the pain is heavy and frequent, then the cause of this situation should be clarified and treated for the cause. Common causes and treatment methods: I. Physiological factors: If in the early stage of pregnancy, only occasional pain in the stomach like menstruation and the pain will be relieved quickly without obvious vaginal bleeding, it can be considered as a normal physiological phenomenon caused by the congestion of the uterus and pelvic cavity after pregnancy, which can generally be relieved by itself. Pathological factors: 1. Pre-eclampsia: miscarriage due to fetal dysplasia or other factors, causing abdominal pain, accompanied by a small amount of vaginal bleeding, the need to perform blood HCG, ultrasound examination, progesterone or dydrogesterone under the guidance of the doctor to perform fetal preservation treatment, if necessary, to terminate the pregnancy; 2. The location is similar to that of menstruation. It is generally recommended to carry out surgical treatment in time to avoid serious consequences such as hemorrhage and uterine cavity infection caused by the rupture of the gestational sac; 3. Digestive system diseases: such as gastroenteritis and intestinal obstruction can cause abdominal pain, which should be promptly seen and treated appropriately. It is recommended to follow the doctor’s prescription for intravenous medication, replenish vitamins and electrolytes, or apply drugs such as montelukast and bifidobacterium to regulate intestinal flora to improve the discomfort, and not to use drugs blindly on your own to avoid affecting the health of the fetus; 4. Gynecological diseases: such as pelvic inflammatory disease and adnexitis can lead to abdominal pain, and a detailed examination should be conducted at the hospital in time to clarify the diagnosis. If the symptoms are not too serious, you can strengthen the local hygiene and often flush the pubic area with warm water. If the symptoms are more serious adnexitis, you can apply cephalosporin antibiotic drugs. Note: During pregnancy, pregnant women should pay attention to bed rest, not too much stress, and keep a relaxed mood. Strengthen dietary nutrition, eat more vegetables and fruits rich in vitamins and proteins, and take folic acid tablets as prescribed by your doctor.
