Menopause and weight
Menopause and Insulin Resistance
Insulin resistance means your cells respond less effectively to insulin, which helps move glucose from the blood into cells. It often causes no obvious symptoms. Around menopause, changes in abdominal fat and activity may make a review of blood glucose and other risk factors useful.

How insulin resistance can affect blood glucose
The pancreas makes insulin. This hormone helps glucose enter muscle, fat, and other cells for use or storage. When cells respond poorly, the pancreas may need to produce more insulin to keep glucose in range. If it can no longer meet that demand, blood glucose can rise.
Prediabetes means blood glucose is above the usual range but below the threshold for type 2 diabetes. Insulin resistance and prediabetes are related terms with different meanings. A clinician usually checks for prediabetes using blood tests of glucose or A1C. Tests that directly measure insulin resistance are mainly used in research.
People with insulin resistance or prediabetes usually have no symptoms. A larger waist, tiredness, or cravings cannot establish the diagnosis. Testing is useful because blood glucose may be abnormal before you notice a change in how you feel.

Menopause is part of the context for a risk assessment
The menopause transition can shift fat distribution toward the abdomen. A larger waist and excess body fat are associated with insulin resistance and diabetes risk. Age and lower activity can also contribute during midlife.
Other important factors include family history of diabetes, previous gestational diabetes, polycystic ovary syndrome, sleep apnea, and certain medications. Bring this history to the appointment, even if a previous glucose result was normal.
NIDDK advises that clinicians may order prediabetes tests from age 35, or earlier when overweight or obesity accompanies other risk factors. The timing should be individualized. Ask when you were last tested and whether repeat screening is appropriate.
- A parent or sibling with diabetes.
- Diabetes during a previous pregnancy.
- A history of PCOS, sleep apnea, or high blood pressure.
- A larger waist, lower activity, or medication associated with glucose changes.
A1C and fasting glucose are the usual starting tests
A1C estimates average blood glucose over about three months. A fasting plasma glucose test measures glucose after fasting, using the instructions provided by the laboratory. An oral glucose tolerance test measures the response after a glucose drink and is used in some situations.
| Test | Prediabetes range |
|---|---|
| A1C | 5.7% to 6.4%. The result reflects average glucose over roughly three months. |
| Fasting plasma glucose | 100 to 125 mg/dL. Follow the laboratory's fasting instructions. |
| Two-hour oral glucose tolerance test | 140 to 199 mg/dL after the glucose drink. |
These ranges are used in US guidance. A clinician interprets the result with your health history and may repeat or use another test when needed. A1C can be less reliable with some blood conditions, including iron deficiency anemia, so mention heavy bleeding or a known anemia diagnosis.
Tests aimed specifically at measuring insulin resistance are mainly used in research. Ask what a proposed fasting insulin test would change in your care. For many people, glucose-related tests and the overall risk assessment are the more useful starting point.
Food and activity can lower the risk of developing diabetes
A structured prevention program can help you make changes that fit daily life. The Diabetes Prevention Program found that a lifestyle program including weight loss and more activity reduced diabetes risk in people already at high risk. NIDDK highlights a loss of 5% to 7% of starting weight as a useful goal for suitable patients.
Meals
Include vegetables, fruit, whole grains, and protein foods. Review portions and calorie-containing drinks when weight loss is appropriate. A dietitian can adapt the plan to preferences and glucose results, and help you choose meals that are nourishing and practical.
Movement
Adults are advised to aim for at least 150 minutes of moderate aerobic activity a week and muscle-strengthening activity on at least two days. Short walks and other sessions can be spread through the week. Start at a level you can tolerate and build gradually.
Sleep and weight management also belong in the discussion. If snoring or severe fatigue makes activity difficult, ask whether sleep apnea or another condition needs assessment. A plan is easier to sustain when those barriers receive treatment.
When medication may be considered
A clinician may consider metformin for selected people with prediabetes to help prevent or delay type 2 diabetes. In the Diabetes Prevention Program, its benefit was particularly notable in younger adults, people with obesity, and women with previous gestational diabetes. The decision should reflect your current risk and medical history.
Weight medication may be considered when its clinical criteria are met. Adults generally need a BMI of at least 30, or at least 27 with a weight-related condition. Eligibility, side effects, pregnancy plans, and other medicines require review. Prediabetes alone does not mean that every weight medicine is appropriate.
If blood pressure or cholesterol is also abnormal, those conditions may need treatment. Ask which results each medicine targets and how progress will be monitored. Bring all medications and supplements to each review.
Hormone therapy can be considered for menopause symptoms. A glucose assessment and diabetes prevention plan should still be discussed directly. Your clinician can coordinate symptom treatment with care for metabolic risk.
Agree on repeat testing and a manageable goal
NIDDK describes repeat diabetes testing at least every three years for people with risk factors whose tests are normal, and yearly for those with prediabetes. A clinician may recommend a different interval when results, symptoms, or treatment change.
At follow-up, review glucose results, blood pressure, activity, and any weight goal. Choose a small number of actions you can maintain, such as a regular walk and a change to a usual drink or meal. A prevention program or dietitian can provide ongoing support.
Ask how you will recognize improvement and which result would prompt a change in treatment. This keeps the plan connected to your actual risk and response over time.
New thirst, frequent urination, or unexplained weight loss needs checking
Diabetes can cause increased thirst, frequent urination, fatigue, blurred vision, or unexplained weight loss. Arrange an assessment if these symptoms are new, including when a previous screening result was normal.
