Short answer: Insulin sensitivity declines through the menopause transition, driven by visceral fat accumulation and lean-mass loss rather than by ageing alone. Ask for HbA1c, fasting glucose, fasting insulin, a lipid panel, and ALT. Resistance training is the most efficient single intervention because skeletal muscle is the main site of glucose disposal; incretin therapy and metformin are the pharmacological options.
What to test
- HbA1c and fasting glucose
- Fasting insulin (for HOMA-IR)
- Lipid panel including triglycerides and HDL
- ALT, for hepatic steatosis
- Blood pressure and waist circumference
Why muscle is the lever
Skeletal muscle disposes of the majority of post-meal glucose. Losing muscle through midlife shrinks that sink, and building it back enlarges it. Resistance training improves insulin sensitivity within weeks, independent of weight change.

Frequently asked questions
Does hormone therapy improve insulin sensitivity?
Randomized data show a small favourable effect on glucose metabolism and a reduced incidence of new-onset diabetes, but hormone therapy is not prescribed for glycaemic control.
Is prediabetes reversible?
Frequently. The Diabetes Prevention Program showed a 58% reduction in progression to diabetes with intensive lifestyle change.
