After pregnancy, women will experience significant changes in their body systems due to large fluctuations in hormone levels, which may cause a series of uncomfortable symptoms. Elevated blood HCG and progesterone levels may lead to fatigue, drowsiness, nausea, vomiting and other symptoms, so you should rest more and avoid heavy physical activities. Choose light and easily digestible food, eat less and more often, avoid overeating, which will increase the burden on the stomach and intestines, and use drugs to promote digestion, such as lactobacillus tablets, if necessary. In addition, you should not be absolutely bed-ridden. Proper activities can promote gastrointestinal peristalsis and relieve early pregnancy reaction. Due to the enlargement and softening of the uterus and pelvic congestion, symptoms such as slight pain in the lower abdomen, soreness and swelling in the lower back and frequent urination may also occur. After 8 weeks of pregnancy, the symptoms will be gradually relieved. If the pregnant woman’s physical condition allows, she can perform appropriate pregnancy health exercises, which can effectively relieve the above symptoms. After 12 weeks of pregnancy, the hormone level will gradually return to the normal level and all kinds of uncomfortable symptoms will disappear. Before 12 weeks of pregnancy, you should treat early pregnancy reaction correctly, keep your mood relaxed, strengthen nutrition and pay attention to rest.
