A risk factor is something that increases your likelihood of getting a disease or condition.

Menopause is a natural process, which usually occurs around the age of 50. However, when the normal menstrual cycle is interrupted prior to age 40 this is thought to be abnormal and is referred to as premature menopause.

Risk factors for premature menopause include:

• Family history of premature menopause
• Surgical removal of the ovaries
• Radiation
• Chemotherapy
• Medications that reduce estrogen levels
• Smoking
• Autoimmune diseases
• Medical treatments (pelvic surgery, surgical removal of ovaries, chemotherapy, or pelvic radiation therapy)
