Management of Fatigue in Perimenopausal Women
Initial Diagnostic Approach
- The American College of Obstetricians and Gynecologists recommends ruling out medical causes of fatigue, such as thyroid disease and diabetes, before attributing symptoms to menopause, by obtaining TSH, free T4, and fasting glucose or HbA1c levels 1
- FSH levels are not reliable markers of menopausal status in perimenopausal women with irregular cycles, as they can fluctuate 1
Understanding Her Hormonal Status
- A woman is considered perimenopausal if she continues to have menstrual cycles, albeit irregularly, which means she has not yet reached menopause 2
- Elevated FSH with relatively preserved estradiol is consistent with perimenopause, where FSH rises as ovarian reserve declines but ovulation still occurs intermittently 1, 2
Treatment Algorithm for Fatigue
- The North American Menopause Society recommends initiating hormone replacement therapy (HRT) with transdermal estradiol 50 μg patches twice weekly, plus micronized progesterone 200 mg nightly, for perimenopausal women with moderate-to-severe vasomotor symptoms 2
- HRT can be initiated during perimenopause and does not need to be delayed until postmenopause, as the benefit-risk profile is most favorable for women under 60 and within 10 years of expected menopause 2
Absolute Contraindications to Screen For
- The American Heart Association recommends screening for absolute contraindications to HRT, including history of breast cancer, hormone-sensitive malignancies, active or history of venous thromboembolism or stroke, and coronary heart disease 2, 3
Expected Benefits of HRT
- HRT reduces hot flashes and night sweats by approximately 75%, and provides the most effective relief of menopausal symptoms compared to all other treatments 2
- HRT prevents accelerated bone loss and provides a 27% reduction in nonvertebral fractures 2
