When there is hidden pain in the right side of the abdomen in early pregnancy, we should consider whether it is physiological pain or pathological pain according to the symptoms, and need to clarify the cause and take appropriate treatment measures. Common causes and treatments: I. Physiological factors: After pregnancy, most of the hidden abdominal pains that appear in some women are physiological changes, mainly due to the squeezing of the organs in the pelvis after the enlargement of the uterus. In addition, the enlargement of the uterus causes the uterine ligaments to be stretched, which is a normal physiological phenomenon and generally does not require special treatment. Pathological factors: 1. Pre-eclampsia: In addition to abdominal pain, there will be a small amount of vaginal bleeding, which will require blood HCG and ultrasound examination, progesterone or dextran under the guidance of the doctor to carry out fetal preservation treatment and, if necessary, termination of pregnancy; 2. Ectopic pregnancy: If the embryo is laid in one of the ovaries or fallopian tubes, after the activity or rupture of ectopic pregnancy at a certain period, it will cause small abdominal pain on one side. It is generally recommended to carry out surgical treatment in time to avoid serious consequences such as hemorrhage and uterine cavity infection due to rupture of the gestational sac. 3. Digestive system diseases: such as acute appendicitis, enteritis and intestinal obstruction can cause abdominal pain, which should be seen in time for appropriate treatment. It is recommended that intravenous medication, vitamin and electrolyte supplementation, or the application of montelukast, bifidobacterium and other drugs to regulate intestinal flora to improve the discomfort, not to blindly use drugs on their own to avoid affecting the health of the fetus; 4, gynecological diseases: such as right adnexitis, twisting or rupture of the right ovarian cyst can cause 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 flush your pubic area with warm water frequently. If the symptoms are more serious adnexitis, medication can be carefully selected under the guidance of a doctor. Note: Pay attention to dietary hygiene, a light diet, reduce the intake of spicy and stimulating foods, ensure adequate rest and sleep, avoid giving excessive exertion, relax your mind and have regular maternity checks.
