There are more sweat glands in the armpits, and this physiological structure determines that the underarm sweating may be particularly serious, which generally belongs to physiological reasons. If it does not affect your life, you do not need to take special treatment. You can use antiperspirant products such as antiperspirant and talcum powder in your armpits, wear comfortable and breathable clothes, clean your armpit hair regularly, and keep your armpit skin clean and fresh, and your symptoms can be significantly relieved. If under normal circumstances, the temperature and humidity are suitable, but the patient’s underarm sweating is abnormally increased, it may be caused by hyperhidrosis and other diseases, it is recommended to go to the hospital for diagnosis in time and follow medical advice for medication or surgery. If it is clear that hyperhidrosis causes particularly serious underarm sweating, topical alum solution and tannic acid solution can be used topically under the guidance of a doctor to astringently stop sweating and deodorize. You can also use anticholinergic drugs such as atropine and belladonna to stop acetylcholine from activating the sweat glands and reducing sweating. For hyperhidrosis due to emotional overload, sedative drugs such as phenobarbital and chlorpromazine can be used for treatment. In addition, local injections of botulinum toxin can also reduce sweat gland activity, thus relieving the symptoms of particularly severe sweating. If the above treatments are not effective, sweat gland excision may be performed at the advice of a physician to relieve sweating symptoms. It should be noted that hypoglycemia, neuroanxiety, diabetes mellitus, and hyperthyroidism can also cause hyperhidrosis, which can manifest as particularly severe underarm sweating and needs to be differentiated from primary hyperhidrosis. For hyperhidrosis induced by the above diseases, it is necessary to actively treat the primary disease, regularly review and physical examination, and promptly channel psychological problems to maintain a good state of mind so as to alleviate the symptoms of hyperhidrosis.
