The pulling pain at the bottom of the abdomen at 36 weeks of pregnancy may be related to the pulling of uterine ligaments, increased estrogen levels, fetal head settlement, etc. The specific situation requires the patient to go to the hospital to find out the cause and then carry out symptomatic treatment. Common causes and treatments: 1, uterine ligaments are pulled: with the development of the fetus in the late stages of pregnancy, the uterus will gradually increase in size, resulting in an increase in intra-abdominal pressure, which will cause the round uterine ligaments to be pulled, thus causing pain. If the fetus in the uterus activities, or due to the uterus pressure bladder, can cause the bottom of the abdomen pulling pain, usually normal physiological phenomenon. Pregnant women need to pay attention to rest, avoid prolonged standing or sedentary, avoid strenuous activities; 2, estrogen levels rise: the body will secrete higher levels of estrogen during pregnancy, under the influence of hormones, can make the ligaments of the symphysis pubis relax, which leads to separation of the symphysis pubis, causing pain. At this time, pregnant women can wear a pelvic girdle under the guidance of a professional doctor to reduce the symptoms of separation of the pubic symphysis, in order to alleviate the pain; 3, fetal head settling: when the fetal head gradually settles into the pelvis, squeezing the local tissues, can also cause pulling-like pain in the abdomen. Generally there is no need for treatment, but if the pregnant woman feels obvious pain and accompanied by a small amount of vaginal bleeding, she should go to the hospital in time to improve the examination and wait for delivery. Precautions: At 36 weeks of pregnancy, pregnant women should pay attention to controlling their own weight and closely monitor their blood pressure to prevent the development of pre-eclampsia, or lead to rapid weight gain and over-size of the fetus. It is also necessary to go to the hospital for fetal heartbeat monitoring to determine whether intrauterine hypoxia is occurring in the fetus and to monitor contractions, and may also increase the amount of activity under the guidance of a medical professional in order to facilitate the smooth progress of vaginal delivery.
