The causes of mid-pregnancy edema include physiological causes, exertion, gestational hypertension, and gestational proteinuria.
1. Physiological reasons: with the increase of pregnancy weeks, the enlarged uterus will compress the pelvic floor tissues and the inferior vena cava, so that venous return is impeded and caused by the ankle and calf mild edema, after appropriate rest can be calf, is a normal physiological phenomenon.
2. Exertion: After pregnancy, when pregnant women walk for a long time or stand for a long time, it will cause mild edema of the lower limbs, which is not accompanied by elevated blood pressure and can be relieved after proper rest.
3. Hypertension in pregnancy: the diagnosis can be made clearly by measuring the elevated blood pressure during the delivery test, which can also cause edema, which can be extended to the face in severe cases, and cannot be relieved or subside after resting, and can be diagnosed clearly by combining the medical history, clinical manifestations and the delivery test.
4. Proteinuria in pregnancy: edema of tissues in pregnancy due to recurrent proteinuria, not accompanied by elevated blood pressure, which cannot be relieved by rest, and can be diagnosed by combining with clinical manifestations, urine routine and liver and kidney function tests.
When edema in mid-pregnancy can go to the hospital to identify the cause and timely treatment.
