Final answer:
The term for excessive hair growth is 'hirsutism,' often caused by hormonal imbalances like in polycystic ovary syndrome or Cushing's syndrome.
Step-by-step explanation:
The term that refers to the condition of excessive hair growth is called hirsutism. Hirsutism is a condition often resulting from an imbalance of hormones, specifically androgens, or can be due to genetic and ethnic factors. Women with hirsutism will find that they have hair growing in areas where it is typically seen in males, such as the face, back, and chest. The hair is usually coarse and pigmented.
Conditions such as polycystic ovary syndrome (PCOS), Cushing's syndrome, and certain medications can lead to hirsutism. In PCOS, for instance, there's an overproduction of androgens which can cause symptoms like irregular menstrual cycles, acne, and excessive hair growth. Cushing's syndrome, which involves the overproduction of cortisol, can also cause hirsutism alongside a 'moon face' appearance, abnormal weight gain, and acne.
Treatment for hirsutism may involve addressing the underlying hormonal imbalance, through medications or lifestyle changes. For instance, in cases of PCOS, managing insulin levels and androgen production can help alleviate the symptoms.
