Women’s swollen feet in summer may be a physiological phenomenon, or it may be caused by hypoproteinemia, deep vein thrombosis of the lower extremities, nephrotic syndrome and other pathological causes. 1. Physiological reasons: standing for a long time or pregnancy can lead to swollen feet. 2. Pathologic causes: (1) Hypoproteinemia: due to the hot weather in summer, the human body usually eats less, causing impaired digestive function, which can lead to hypoproteinemia, resulting in malnutrition of the organism, which can also cause swollen feet.
