Why am I so tired in perimenopause?
Understand fatigue causes during perimenopause and how to track energy levels for pattern clarity.
Fatigue during perimenopause has multiple interconnected causes. Tracking helps identify which factors contribute most to your energy patterns.
Common causes of perimenopause fatigue
Fatigue can result from:
- Night sweats disrupting sleep quality
- Hormonal fluctuations affecting energy metabolism
- Mood changes (anxiety, low mood) draining mental energy
- Iron levels changing with heavier periods
How to track energy levels
Log daily with:
- Morning, afternoon, and evening energy ratings (0-10)
- Sleep quality and duration from the previous night
- Night sweat count if applicable
- Context tags: caffeine, exercise, stress level
Patterns to identify
Review your timeline weekly for:
- Days when sleep quality predicts next-day energy
- Time-of-day energy dips
- Correlation with hot flash or night sweat frequency
- Impact of exercise on same-day and next-day energy
What to bring to your physician
Prepare answers for:
- "What's your average sleep quality score on high-energy vs low-energy days?"
- "When do energy dips most commonly occur?"
- "How often do night sweats disrupt your sleep?"
