Sweating on one side of the head and no sweating on the other side may be caused by abnormal sweat gland function or neurological damage.
1. Sweat gland dysfunction: such as congenital sweat gland underdevelopment, scleroderma, tumor, burn, skin transplantation and radiation dermatitis, etc., which leads to local sweat gland damage, sweat gland function abnormality and cause the disappearance of sweating on one side, which can be identified according to the patient’s medical history and relevant physical examination.
2. Neurological damage: it refers to the dysfunction of the nerve pathway that activates the sweat glands, such as medullary damage, hypothalamic tumor, disease of the lower end of the brainstem, etc., so that the central nerve impulses reaching the sweat glands are lacking, which causes the absence of sweating on one side, which can be diagnosed by perfect craniocerebral CT or nuclear magnetic diagnosis.
If the patient often has no sweat on one side of the head, it is recommended to consult a doctor in time, complete the above examination, clarify the cause of the disease and treat the cause under the guidance of the doctor.
