The causes of sweating and whitening of the soles of the feet include physiological factors, athlete’s foot, anemia, and venous thrombosis of the lower extremities. 1. Physiological factors: when the foot is immersed in water for a long time, the skin stratum corneum absorbs a lot of water, and the phenomenon of white sweating on the soles of the feet can occur at this time. 2. Tinea pedis: impregnated erosion type tinea pedis occurs in tinea pedis toe seams, manifested as whitish skin impregnation, the surface is soft and easy to peel off. 3. anemia: skin and mucous membrane pallor caused by intradermal capillary ischemia is the most common sign of anemia, so anemia may also cause the phenomenon of white sweating on the soles of the feet. 4. Lower extremity venous thrombosis: If the lower extremity veins have thrombosis, these thrombi will block the veins leading to insufficient blood flow in the feet, and the phenomenon of white sweating will also occur. There may be other reasons for the white sweating on the soles of the feet, so you should consult a doctor in time after eliminating the physiological factors, and have the relevant treatment after the doctor’s examination and diagnosis.
