The swelling of the feet in the seventh month of pregnancy is a common physiological phenomenon. It is recommended that pregnant women should take proper rest and elevate both lower limbs during rest to increase venous return and reduce edema. At the same time, pregnant women should also pay attention to salt limitation, with the salt in food not exceeding 6 g per day, and pay attention to increasing the intake of high-quality protein foods, such as lean meat, eggs and milk, which can reduce the edema caused by hypoproteinemia, taking appropriate calcium supplements, and eating foods rich in potassium ions, such as bananas and oranges, which can reduce the retention of sodium and water in the body. Pregnant women are advised to pay attention to blood pressure measurement during pregnancy checkups and to treat gestational hypertension if the swelling of the feet is caused by elevated blood pressure.
