Menopause is clinically diagnosed after 12 months of amenorrhea (lack of mentruation) without other causes, such as surgical removal of the ovaries, chemotherapy or radiotherapy, or primary ovarian insufficiency. It usually occurs after 45 years of age and is considered abnormal if it occurs prior to 40 years of age. Blood and urine tests can be conducted to detect changes in hormone levels.[1]
