Menopause typically starts with a period called perimenopause, during which hormone levels fluctuate and menstrual cycles change. Most people begin perimenopause in their late 40s, with symptoms such as irregular periods, hot flashes, night sweats, mood changes, and sleep disturbances. Menopause itself is officially reached when a person has not had a menstrual period for 12 consecutive months. On average, menopause occurs around age 51 to 52, though this can vary. Menopause before age 45 is considered early, and before age 40 is termed premature menopause. The symptoms of perimenopause can start anywhere from the mid-30s to mid-40s and typically last for a few years leading up to menopause. In summary:
- Perimenopause usually begins in the late 40s.
- Menopause is confirmed after 12 months without a period.
- Average age for menopause is about 51-52 years.
- Early menopause is before 45, premature menopause before 40.
The timing and symptoms vary for each individual.
