The causes of hirsutism can vary and may include:

• 1. Polycystic Ovary Syndrome (PCOS): PCOS is a common hormonal disorder that can cause hirsutism. In PCOS, the ovaries produce higher levels of androgens, leading to the development of symptoms such as irregular periods, ovarian cysts, and hirsutism.
• 2. Idiopathic Hirsutism: In some cases, the cause of hirsutism cannot be identified, and it is referred to as idiopathic hirsutism. This means that there is no underlying hormonal disorder or specific medical condition causing the excess hair growth.
• 3. Medications: Certain medications, such as anabolic steroids, some hormone therapies, and certain medications used to treat conditions like endometriosis, can cause hirsutism as a side effect.
• 4. Adrenal Gland Disorders: Rarely, hirsutism can be caused by adrenal gland disorders, such as congenital adrenal hyperplasia or adrenal tumors, which can lead to increased androgen production.
• 5. Cushing's Syndrome: This condition occurs when there is an excessive production of cortisol, a hormone produced by the adrenal glands. Cushing's syndrome can cause hirsutism along with other symptoms such as weight gain, high blood pressure, and a rounded face.
