Glyvon HealthWhat insulin resistance means
Insulin resistance happens when muscle, liver and fat cells respond less effectively to insulin. The pancreas may compensate by releasing more insulin, so blood glucose can look normal for a while even when fasting insulin is already elevated.
An insulin resistance calculator should therefore be read as a screening and tracking aid, not as a diagnosis. HOMA-IR, fasting insulin, waist circumference, HbA1c, lipids and blood pressure all help describe metabolic health.
Common symptoms and risk signals
- Fatigue or sleepiness after meals, especially high-carbohydrate meals.
- Frequent cravings, hunger soon after eating or difficulty losing abdominal weight.
- Dark, velvety skin changes on the neck or underarms, sometimes called acanthosis nigricans.
- High triglycerides, low HDL, elevated blood pressure, fatty liver markers or polycystic ovary syndrome.
Symptoms are not specific. If you have symptoms or abnormal lab results, discuss them with a qualified clinician.
HOMA-IR formula and fasting insulin
HOMA-IR estimates insulin resistance from fasting glucose and fasting insulin collected from the same fasting blood draw. In mg/dL units, the common formula is:
HOMA-IR = fasting glucose x fasting insulin / 405
This insulin resistance page is intentionally broader than a formula tool. For exact calculation and score handling, use the dedicated HOMA-IR calculator.
Result ranges for screening
| Marker | Typical interpretation | What to do next |
|---|---|---|
| Fasting insulin below 10 uIU/mL | Often considered more insulin-sensitive, depending on lab and context. | Track alongside glucose, HbA1c and lifestyle patterns. |
| Fasting insulin 10-15 uIU/mL | May suggest early compensation or borderline insulin resistance. | Review nutrition, activity, sleep and repeat testing with a clinician. |
| Fasting insulin above 15 uIU/mL | Often treated as a stronger insulin resistance signal. | Ask about full metabolic evaluation and follow-up timing. |
| HOMA-IR above about 2.5 | Commonly used as an insulin resistance threshold in many references. | Use lab-specific guidance and clinician interpretation. |
When to speak to a clinician
Book a medical review if you have repeated abnormal fasting glucose, high fasting insulin, elevated HbA1c, symptoms of diabetes, pregnancy, polycystic ovary syndrome, fatty liver, cardiovascular risk factors or a strong family history of type 2 diabetes.
Seek urgent care for severe thirst, frequent urination, unexplained weight loss, vomiting, confusion or very high glucose readings.
Track metabolic health with Glyvon Health
Glyvon Health helps you keep fasting glucose, fasting insulin, HOMA-IR, HbA1c, meals, activity and CGM data in one calm record. The goal is not to replace your clinician; it is to make appointments clearer with trends, context and structured notes.
Frequently asked questions
Is this page the same as a HOMA-IR calculator?
+
No. This is a broader insulin resistance calculator guide. For the formula-specific tool, use the dedicated Glyvon Health HOMA-IR calculator.
Do I need fasting insulin?
+
Yes, fasting insulin is needed for HOMA-IR. It is most useful when collected with fasting glucose from the same blood draw.
Can insulin resistance be reversed?
+
Many people improve insulin sensitivity with weight management, resistance training, aerobic activity, sleep improvement and nutrition changes. Medical treatment depends on the person.
Is Glyvon Health a diagnostic tool?
+
No. Glyvon Health supports tracking, education and appointment preparation. Medical decisions should be made with a healthcare professional.
