Explanation

Menopause is a natural biological process that marks the end of a woman's menstrual cycle. It usually occurs between the ages of 45 and 55 but can occur earlier or later. During menopause, the ovaries stop releasing eggs and the production of hormones such as estrogen and progesterone declines. This can cause a variety of symptoms, such as hot flashes, night sweats, vaginal dryness, mood changes, and sleep disturbances. Menopause also increases the risk of certain health conditions such as osteoporosis and heart disease. While menopause is a normal part of aging, it is important to talk to a healthcare provider about any symptoms or concerns.
