Step 1: Definition of Menopause.
Menopause refers to the natural biological process marking the cessation of a woman's menstrual cycles for 12 consecutive months, indicating the end of her reproductive years. It typically occurs around age 50-52.
Step 2: Early Menopause.
Early menopause is defined as menopause occurring between ages 40 and 45. It is considered earlier than usual but still within a recognized age range for menopause. It may occur due to genetic factors, medical conditions, or lifestyle factors.
Step 3: Premature Menopause.
Premature menopause refers to the onset of menopause before the age of 40. This can result from various causes, including autoimmune diseases, chemotherapy, genetic conditions, or surgical removal of ovaries.
