It is not normal for a woman to have swollen feet in the sixth month of pregnancy. The sixth month of pregnancy is the middle of pregnancy, during which the fetus grows and develops less, which does not cause pressure on the pelvic blood circulation and slow down the blood circulation in the lower limbs. When there is swelling of the feet, we should also pay attention to exclude whether there is hypertension in pregnancy or pregnancy combined with chronic kidney disease, we need to go to the hospital for routine urine and kidney function tests, if there is protein in the urine or high blood pressure, we need to give timely rest, low salt diet, antihypertensive drugs and other symptomatic treatment. Normally, in late pregnancy, that is, after the 8th month of pregnancy, due to the excessive enlargement of the uterus and the slowing down of pelvic blood circulation, swelling of the feet will occur, which is lighter in the morning and heavier in the afternoon and evening.
