Pregnancy with a stuffy and uncomfortable stomach may be caused by the change of hormone level in the pregnant woman’s body in the early stage of pregnancy, or it may be caused by the increasing number of weeks of pregnancy and the increasing size of the fetus, which causes pressure on other organs around, or it may be caused by gastrointestinal dysfunction, which requires different treatment methods according to different causes: 1. Change of hormone level: In the early stage of pregnancy, the surge of hormone level will lead to contraction of the uterus, causing the pregnant woman to experience small abdominal stuffiness and stiffness, and in serious cases, abdominal pain and vaginal bleeding may occur. If the pregnant woman only has abdominal discomfort, but no abdominal pain and vaginal bleeding, there is no need to worry, as this is a normal physiological reaction of pregnant women in early pregnancy. On the contrary, if there is abdominal pain and vaginal bleeding, you should be alert to the possibility of pre-miscarriage, you need to go to the obstetrics department of the hospital as soon as possible, and carry out fetal preservation treatment; 2, fetal enlargement and compression: if it is in the middle and late pregnancy, there is a stuffy and uncomfortable stomach, it may be caused by the fetus enlargement and compression of the stomach and intestines of pregnant women. In this case, pregnant women should pay attention to rest and sleep in a left-sided position to relieve the discomfort; 3, gastrointestinal disorders: if pregnant women do not eat properly during pregnancy, such as eating spicy and stimulating or too greasy food, it may lead to gastrointestinal disorders, and then bloating, constipation, indigestion and other symptoms, resulting in pregnant women with a stuffy stomach. In this case, pregnant women can take probiotics or drugs that promote gastrointestinal digestion under the guidance of a doctor to regulate intestinal flora, improve gastrointestinal function, promote gastrointestinal exhaust and relieve constipation symptoms. In addition, pregnant women should pay attention to eating less and more meals, regulate their own eating habits, and try to eat less spicy, greasy, cold and stimulating food.
