The feet of women in the early stages of pregnancy will not be swollen because the uterus is small in the early stages of pregnancy and will not cause pressure on the blood vessels in the pelvis. If there is mild edema in the feet, consider whether it is caused by recent overexertion and poor local blood circulation due to prolonged standing or squatting. It is recommended to relieve foot fatigue by applying local heat or soaking the feet to promote local blood circulation. However, women are prone to have symptoms of mild edema in the feet due to increased venous pressure in the lower extremities after reaching the second trimester, which is due to the increase of pregnancy, the uterus will cause certain pressure on the pelvic vessels and the decrease of albumin in the body, and there is a possibility of edema in both lower extremities, which can be relieved after rest. It is also important to closely monitor the blood pressure during pregnancy because pregnant women with gestational hypertension are also prone to lower limb edema.
