The main thing to do to relieve swollen feet in pregnant women is to do the following: first, elevate the lower limbs when sitting. Secondly, proper exercise or walking will help to relieve swollen feet. The third one is to sleep on the left side as much as possible, which will promote the relief of swollen feet. Pregnant women are prone to edema due to water and sodium retention. In addition, an enlarged uterus can also compress the inferior vena cava, which can also lead to edema. The following measures can be taken to relieve edema: First, let the patient sit with the lower extremities elevated as much as possible, so that the edema will subside after the water from the lower extremities flows back to the trunk position. Secondly, let the patient take a walk as much as possible, which can also relieve the patient’s foot swelling. The third one is to limit the salt intake of the patient, which can also relieve the swelling of the foot. Fourth, the left lateral position can promote local circulation, which can also relieve foot swelling.
