Swollen feet and necks of pregnant women can be divided into physiological conditions and pathological conditions. The physiological type is mainly due to the fact that after pregnancy, with the enlargement of the uterus can compress the inferior vena cava of the pregnant woman, resulting in the obstruction of the venous and lymphatic return of the lower limbs, thus preventing a smooth return flow, making the feet and lower limbs edema, which can be relieved in the morning or after rest, and the swelling is more serious in the afternoon, evening or when standing or walking more, and even some pregnant women, when Some pregnant women may even have sunken edema when pressing on their calves. The most common and easiest way to rule out hypertension during pregnancy is to have a routine urine test to see if there is any positive urine protein, and to measure blood pressure to see if there is high blood pressure. If there is an increase in blood pressure and a positive urine protein, the swelling of the feet or even the whole body of the pregnant woman may also be caused.
