Numbness in the hands and feet after pregnancy is considered to be caused by poor peripheral circulation due to sodium and water retention and obstruction of venous return. It is recommended that pregnant women should adjust their dietary structure and increase the intake of high-quality protein, which can reduce edema during pregnancy. It is also recommended that pregnant women should pay attention to salt limitation, and the amount of salt consumed should not exceed 6g per day. It is recommended that pregnant women should pay attention to potassium supplementation and eat more bananas and oranges, which can promote sodium discharge from the body and reduce the symptoms of edema, and pay attention to increasing the amount of exercise, moving the limbs or soaking the feet in hot water, which can also promote blood circulation, increase venous return and reduce edema and tingling of the hands and feet.
