Continuous Glucose Monitoring (CGM)
Medical technology originally developed for diabetes management
Continuous glucose monitors are small wearable sensors that track blood sugar levels throughout the day, showing how food, exercise, sleep, and stress affect your metabolism in real-time. While most research has focused on people with diabetes, some evidence suggests CGMs can help healthy individuals identify patterns and optimize meal timing and exercise. The declining estrogen of menopause often increases insulin resistance, making glucose monitoring particularly relevant for women in this transition, though direct studies in menopausal populations remain limited.

What we do not know
We don't know the optimal glucose ranges for healthy menopausal women, as most research targets are based on diabetic populations. There's insufficient data on whether short-term glucose spikes in healthy women predict long-term health outcomes or if avoiding them provides meaningful benefits. We also lack studies on whether CGM use leads to sustained behavioral changes or improved metabolic health specifically during the menopause transition. The psychological impact of constant glucose monitoring in healthy women hasn't been thoroughly studied.
How to access this approach
Prescription CGMs like Dexcom G7 or FreeStyle Libre require a doctor's order and may be covered by insurance if you have prediabetes or diabetes. Over-the-counter options include Lingo by Abbott or Stelo by Dexcom, available without prescription but typically cost $70-100 per month. Many functional medicine doctors will prescribe CGMs for metabolic optimization even without diabetes. Some direct-to-consumer companies like Levels or Nutrisense provide CGMs with coaching, though these are more expensive. Start by discussing with your primary care doctor or endocrinologist about your specific metabolic concerns during menopause.
Cost: $50-150 per sensor (typically worn for 14 days). No ongoing prescription required.
Important to know
Women with diabetes should use CGM only under medical supervision with appropriate targets. CGM data can generate significant anxiety in some women — ensure you have support to interpret the data before starting.
A word from Rose
"I include every approach on this site because real women have found it genuinely helpful — and I take that seriously as evidence even when the clinical trials are limited. The numbers tell you the odds. Your own experience tells you what works for your body. Give it a fair trial, track how you feel, and trust what you observe."
