Perimenopause Symptoms: Understanding the Signs and Changes
Introduction
Perimenopause is a natural stage in a woman’s life, yet many women enter it without fully understanding what is happening to their bodies. Periods may suddenly become unpredictable, sleep can become difficult, moods may change, and symptoms such as hot flashes, brain fog, fatigue, and joint discomfort can begin appearing seemingly without explanation.
Perimenopause refers to the transitional period leading up to menopause. It commonly begins during a woman’s 40s, although some women notice changes earlier. Menopause itself typically occurs between ages 45 and 55, with the average age in the United States around 52.
The symptoms can also last much longer than many expect. Research from the Study of Women’s Health Across the Nation (SWAN) found that frequent vasomotor symptoms such as hot flashes and night sweats lasted for a median of approximately 7.4 years.
Understanding perimenopause symptoms can help women recognize these changes earlier, seek appropriate medical advice, and find strategies that make the transition easier to manage.
