Perimenopause Guides

Perimenopause before 40 is uncommon and carries different health implications than perimenopause at the typical age. Here's what early onset means clinically and how it is managed.

Hot flashes and night sweats are vasomotor symptoms caused by the hypothalamus misreading core body temperature as estrogen declines. Here's the clinical explanation and evidence on treatment options.

Perimenopause typically lasts 4-8 years, though some women experience it for 10 or more. The final 1-2 years before the last period are usually the most intense.

Hormone replacement therapy is the most effective treatment for perimenopause symptoms. Here's what the evidence shows, who benefits, and what the current guidance says about risks.

Late perimenopause has distinct signs — cycles skipping months, intensifying vasomotor symptoms, and new genitourinary symptoms. Here's what distinguishes the final phase from earlier perimenopause.

Declining estrogen during perimenopause affects dopamine regulation — the same pathway disrupted in ADHD. This guide explains why perimenopause intensifies ADHD symptoms and what to do about it.

Anxiety during perimenopause has a neurobiological basis in estrogen's effects on GABA and serotonin systems. Here's how to distinguish perimenopause-related anxiety from generalized anxiety disorder and what the evidence shows for treatment.

Perimenopause before 40 is uncommon but real. Women in their mid-to-late 30s experiencing cycle changes and new symptoms are often dismissed. Here's what to watch for and when to seek evaluation.

The early 40s is a common age for perimenopause to begin. Cycle changes are often the first sign, followed by sleep disruption and new mood symptoms. Here's what to expect.

The mid-40s is when perimenopause symptoms often intensify. Hot flashes become more frequent, sleep becomes harder to maintain, and mood symptoms often peak in this phase.

By age 45, the majority of women are in some stage of perimenopause. Here's what the research shows about symptoms, cycle changes, and health priorities at this stage.

At 47, many women are entering late perimenopause — cycles skipping months, vasomotor symptoms often at their most intense. Here's what is happening and what to do.
