# The Wellness Rundown

> Evidence-based perimenopause and midlife health content for women in their late 30s through 50s.

The Wellness Rundown covers the biology behind common perimenopause symptoms — sleep disruption, fatigue, gut changes, brain fog, anxiety, weight gain — and the evidence-backed interventions that help. Written by Lauren Walsh. No filler, no fear-mongering. Just clear explanations of what's changing and what the research says works.

## Core Topics

- **Fatigue & energy**: The mitochondrial and hormonal story behind perimenopause exhaustion
- **Gut health**: How the microbiome shifts in your 40s and what to do about it
- **Brain fog**: The biology of cognitive changes in perimenopause
