What Is Perimenopause?
Perimenopause is the transition period leading up to menopause, when your body gradually produces less estrogen and progesterone. It typically starts between ages 35 and 45 — most women notice the first changes in their early 40s — and can last anywhere from 4 to 10 years before periods stop permanently.
During this time, fluctuating hormone levels can cause a wide range of perimenopause symptoms: irregular periods, hot flashes, night sweats, brain fog, anxiety, mood swings, insomnia, weight gain, and many others. Because symptoms overlap with stress, aging, and other conditions, many women go years without realizing perimenopause is the cause.
Tracking your symptoms consistently is one of the most effective ways to understand what is happening in your body. It helps you identify patterns, recognize triggers, and have more productive conversations with your healthcare provider about perimenopause treatment options and natural remedies.
