Hirsuitism
Hirsutism is defined as excessive and increased hair growth in women in locations where the growth refers to a male pattern of body hair and it is therefore primarily of cosmetic and psychological concern. Hirsutism is a symptom rather than a disease and may be a sign of a more serious medical indication, especially if it develops well after puberty.
The cause of hirsutism can be either an increased level of androgens (male hormones) or an over sensitivity of hair follicles to androgens. Male hormones such as testosterone stimulate hair growth, increase size and intensify the growth and pigmentation of hair. Other symptoms associated with a high level of male hormones include acne and deepening of the voice and increased muscle mass.
Growing evidence implicates high circulating levels of insulin in women to the development of hirsutism. This theory is consistent with the observation that obese (and thus presumably insulin resistant hyperinsulinemic) women are at high risk of becoming hirsute. Further, treatments that lower insulin levels will lead to a reduction in hirsutism.
It is speculated that insulin, at high enough concentration, stimulates the ovarian theca cells to produce androgens.
The following may be some of the conditions that may increase a woman's normally low level of male hormones:
- Polycystic ovary syndrome
- Cushing's disease
- Tumors in the ovaries or adrenal gland (cancer)
- Certain medications
- Congenital adrenal hyperplasia
- Insulin resistance
- Hormone imbalance
- Genetics
- Pregnancy
- Aging
Hirsutism only affects women, since the rising of androgens causes a male pattern of body hair, particularly in locations where women normally do not develop terminal hair within their puberty (chest, abdomen, back and face). The medical term for excessive hair growth that affect both men and women is hypertrichosis.
Many women with unwanted hair seek methods of hair removal to control the appearance of hirsutism. But the actual causes should be evaluated by physicians, who can conduct blood tests, pinpoint the specific origin of the abnormal hair growth, and advise on the best course of treatment.
If you have a reason to think you are suffering with the above condition please contact myself your GP or follow the links to the Institute of Trichologists to find your nearest Qualified Trichologist*.
