Women are troubled by long hair around their mouths, forearms and calves. In medicine, the hair density of any part increases, lengthens, thickens and turns black when it exceeds the normal limit, which is called hirsutism. Physiological hirsutism and non-physiological hirsutism. Physiological hirsutism can be seen in pregnant women and generally disappears within 6 months after delivery. Non-physiological hirsutism is mostly endocrine dysfunction disease, and a few are one of the clinical manifestations of genetic syndrome. Non-physiological hirsutism is most common in bilateral polycystic ovary syndrome, and may also be caused by pituitary tumors or adrenal cortical tumors. Therefore, these patients may be accompanied by endocrine disorders and menstrual disorders. Long-term use of corticosteroids or androgens can also lead to hirsutism in women. In addition, the exact cause of hirsutism is still unknown, which may be related to the increased sensitivity of local hair follicles to androgen. Treatment of hirsutism Patients with hirsutism should first find out the cause of hirsutism and treat it according to the cause. Hair growth that is not hirsutism, or familial body hirsutism, does not need to be treated. For patients with polycystic ovary, ovulation induction and other treatment methods can be used; People with menstrual disorders regulate menstruation; Endocrine disorders, according to the results of endocrine determination combined with clinical targeted treatment; Patients with ovarian, adrenal or pituitary tumors should have their tumors removed. No matter what the cause of hirsutism is, it is not appropriate for some patients to blindly use various depilation creams or even "electrolytic depilation". Chemical hair removal sometimes damages the skin, while mechanical hair removal does not damage hair follicles, but hair still grows back.
