Based on what I have read, forced menopause usually occurs after a medical treatment such as chemotherapy or other cancer treatments. Women who have experienced this, did not undergo the typical transition process or the perimenopause, which leads to abrupt physical and emotional changes, as a result of the shut down of production of estrogen and progesterone (the two essential hormones that support the menstrual cycle and fertility). When this occurs, women become more prone to low bone density, osteoporosis and fracture, and have a higher risk of acquiring heart disease. Compared to women who undergo menopause naturally, the effects are more intense with forced menopause. This includes: hot flashes, night sweats, mood swings, depression, vaginal dryness, and low libido.
