PerimenopausePerimenopause Periods: What Changes, What's Normal, and When to Get Checked

The transition averages about four years. Frequent hot flashes run a median of 7.4. What eases once it ends, what doesn't, and where the sources split.
About Perimenopause
Readers here learn to place themselves against a real staging framework rather than a symptom list, to read a lab result for what it can establish, and to arrive at a clinical conversation with better questions. Begin with the pillar guide below, then follow the links to your specific question.
Perimenopause is a defined clinical stage, not a vague label for feeling unwell in midlife. These guides start from the published staging criteria and work outward: the typical age range, how long the transition lasts, and how it differs from menopause itself — a distinction that everyday language blurs and that matters for what you do next.
