Cold and sweaty feet in men may be caused by hypoglycemia, anemia, cardiac weakness, hyperhidrosis, and psychological factors. 1. Hypoglycemia: If a male patient is excessively hungry, it may lead to lower blood sugar levels in the blood. When the blood sugar level is lower than normal, symptoms such as cold hands and feet, sweating, fatigue or pallor may occur. 2. Anemia: Anemia patients may cause ischemia and lack of oxygen in organs and tissues, which may reduce the amount of blood circulating in the extremities. The symptoms of cold hands and feet and sweating are more obvious in patients with severe anemia. 3. Weakened heart function: when male patients have weaker heart function, the blood supply function of the patient’s heart will gradually weaken, causing abnormal peripheral circulation in the limbs and cold and sweaty hands and feet. 4. Hyperhidrosis: cold and sweaty feet in men may also be caused by hyperhidrosis, which is abnormal sweating in patients, caused by excessive secretion of sweat by small sweat glands. And generalized hyperhidrosis may be an abnormal physiological response. 5. Psychological factors: If the spirit of excessive tension, excessive irritability, overwork and other psychological factors, are likely to lead to sympathetic nerve excitation, resulting in cold feet, increased sweating and other conditions. Men with cold feet sweating should go to the hospital in a timely manner, after a clear diagnosis to give targeted treatment and treatment.
