Excessive sweating in women may be caused by exercise, hyperthyroidism, menopausal syndrome and other reasons. 1. Exercise: Prolonged strenuous activities, mental tension and other factors lead to sympathetic nerve excitation, which governs the sweat glands to secrete sweat, and can also cause excessive sweating in women. If the patient does not have obvious symptoms such as fatigue and mental weakness, there is usually no need to deal with it. 2. Hyperthyroidism: due to the overproduction of thyroid hormones, which stimulates metabolism and sympathetic nerve excitation, resulting in increased metabolic rate, manifested in symptoms such as fear of heat and excessive sweating. 3. Menopausal syndrome: fluctuation or decrease of sex hormone during menopause will cause autonomic nervous system dysfunction, which is manifested by unstable vasodilatation and contraction function, resulting in hot flashes, sweating and other symptoms. It is often accompanied by emotional instability, changes in menstrual cycle, insomnia and other symptoms. In addition to the above, excessive sweating in women can also be caused by other reasons. It is recommended to consult a doctor in time, follow the doctor’s instructions for further examination, clarify the cause with the help of the doctor, and actively cooperate with the doctor to deal with or treat the problem.
