Women who are hot but not feverish may be the cause of perimenopausal syndrome, hyperthyroidism, autonomic disorders, diabetic peripheral neuropathy, etc., and need to be treated for the cause of the disease. 1. Perimenopausal syndrome: female patients in this period due to the physiological decline in ovarian function, estrogen synthesis and secretion is reduced, resulting in capillary contraction and diastolic dysfunction, so you will feel hot but not fever. You need to maintain an optimistic mindset, reasonable rest, moderate exercise, and follow the doctor’s instructions to take glutamine, estradiol, medroxyprogesterone acetate and other treatments. 2. Hyperthyroidism: hyperthyroidism leads to excessive synthesis of thyroid hormones, which act on the cells of the body, leading to hypermetabolism, increased heat production, and self-consciousness of the body hot. You need to take anti-thyroid drugs such as propylthiouracil and methimazole as prescribed, or through iodine 131 radiation therapy or surgery. 3. Autonomic disorder: the balance between sympathetic and vagus nerves is abnormal, and the sympathetic nerves are overexcited and cause this symptom. It can be treated with drugs such as glutamine, methylcobalamin and vitamin B1. 4. Diabetic peripheral neuropathy: long-term high blood sugar causes stress injury, leading to peripheral nerve dysfunction, so the symptoms will appear. You need to take metformin, rosiglitazone, biaglizine and other hypoglycemic drugs or subcutaneous injection of insulin to lower blood sugar, and use epinastat, methylcobalamin, lipoic acid and other drugs to nourish the nerves. The above are only some of the common causes. If the symptoms persist, you should seek medical advice for a definitive diagnosis. The use of drugs must follow the doctor’s instructions, not blindly use their own drugs, in order to avoid adverse consequences.
