This document summarizes menopause and perimenopause, including common symptoms, hormone replacement therapy options, lifestyle changes, and alternative treatments. It defines menopause as when a woman's ovaries stop producing eggs and menstruation stops. Perimenopause is the transition period before menopause, when periods become irregular. Common symptoms include hot flashes, night sweats, sleep problems, and mood changes. Hormone replacement therapy can help relieve symptoms but also has risks if used long term or in large amounts. Lifestyle changes like diet, exercise, and stress reduction are recommended to help reduce symptoms without hormones.
