If you have a family history of type 2 diabetes, have noticed changes in your health, or simply want to understand your risk, knowing what to look for is a good first step. Testing can help identify prediabetes and related concerns, even though there is no single routine blood test that directly diagnoses insulin resistance.
During Diabetes Awareness Month, Diverse Health Services is helping patients connect practical questions about blood sugar with appropriate testing, nutrition, and everyday habits. Here's what insulin resistance means, what signs deserve attention, and how to start a useful conversation with your healthcare team.
What is insulin resistance?
Insulin is a hormone made by the pancreas. After you eat, insulin helps glucose move from your bloodstream into cells that use it for energy. In insulin resistance, cells in the muscles, liver, and fat tissue do not respond to insulin as effectively as they should.
At first, the pancreas may produce extra insulin to keep blood glucose in a normal range. Over time, it may no longer keep up, and glucose can begin to rise. This is one reason insulin resistance may be present before someone has an abnormal A1C result.
Insulin resistance, prediabetes, and type 2 diabetes are related but different. Prediabetes means blood glucose is above the normal range but below the diabetes range. Type 2 diabetes develops when the body cannot maintain blood glucose within a healthy range. Not everyone with insulin resistance will develop diabetes.
What are the early signs of insulin resistance?
The most important fact is that insulin resistance often has no symptoms. Feeling tired, having cravings, or gaining weight does not automatically mean you are insulin resistant. However, the following findings can be reasons to review your overall risk.
Dark, velvety patches of skin
Acanthosis nigricans is a skin change that may appear as darker, thicker, or velvety skin, especially around the neck, armpits, or groin. It can be associated with insulin resistance, but it also has other possible causes. A new or changing patch should be evaluated rather than treated as a diagnosis.
Changes in waist size, blood pressure, or cholesterol
Carrying excess weight around the waist, having high blood pressure, or having elevated triglycerides and low HDL cholesterol can be associated with greater metabolic risk. Your provider may consider these findings together with your age, activity level, medications, and health history.
A history that raises your risk
A close family member with type 2 diabetes, a history of gestational diabetes, or polycystic ovary syndrome (PCOS) can make a blood sugar discussion especially worthwhile. Risk also rises with age and physical inactivity. None of these factors proves that you have insulin resistance.
Symptoms that may signal elevated blood sugar
Frequent urination, unusual thirst, blurry vision, and unexplained weight loss are possible symptoms of diabetes rather than reliable early signs of insulin resistance. Contact your medical provider if these symptoms develop, particularly if they are persistent or worsening.
How can you check for insulin resistance or prediabetes?
Healthcare professionals usually assess risk and test for prediabetes or diabetes rather than ordering a direct insulin-resistance test. There is no single routine test that can confirm insulin resistance for everyone. A clinician may recommend one or more of the following:
- Hemoglobin A1C: Shows average blood glucose over approximately the past three months. An A1C of 5.7% to 6.4% is in the prediabetes range; 6.5% or above is in the diabetes range, generally requiring confirmation.
- Fasting plasma glucose: Measures glucose after a period without food. A value of 100 to 125 mg/dL falls in the prediabetes range; 126 mg/dL or above is in the diabetes range, generally requiring confirmation.
- Oral glucose tolerance test: Checks how the body handles a measured glucose drink over time. This may be appropriate when other tests do not provide a clear answer.
A lipid panel, blood pressure reading, and other measurements may also help assess metabolic and cardiovascular risk. Your provider determines which tests are appropriate, how to interpret them, and whether repeat or additional testing is needed.
Where the DHS VIP Panel fits
The Diverse Health Services VIP Panel includes Hemoglobin A1C, a comprehensive metabolic panel (CMP), lipid panel, CBC with Differentials, iron, several thyroid markers, vitamin D, and other measurements. It offers a broader view of metabolic and general health markers that may help guide a conversation about blood sugar, nutrition, and wellness.
The VIP Panel is not a standalone test for insulin resistance, and its full set of markers may not be necessary for every patient. Through Functional Medicine and Lab Testing, the DHS team can discuss the questions you want to answer and the testing options that may fit your situation.
What can you do if you are concerned about insulin resistance?
You do not need a complicated routine to take useful steps. Begin with changes that you can maintain and review them with your medical team, especially if you have diabetes or take medication that affects blood glucose.
- Build regular meals around vegetables, fiber-rich carbohydrates, and satisfying protein sources rather than relying on sugary drinks or frequent highly processed snacks.
- Make movement a regular part of the day. Walking after meals, resistance exercise, and other activities can all contribute to metabolic health when appropriate for your abilities.
- Protect adequate sleep and look for realistic ways to manage stress, since daily routines can affect glucose regulation.
- If you are above your recommended weight, ask your clinician whether gradual weight reduction would be helpful. Even modest changes have been shown to reduce the risk of type 2 diabetes in people with prediabetes.
These steps may improve insulin sensitivity and reduce risk, but they do not replace evaluation or prescribed treatment. If testing shows prediabetes, ask about a structured diabetes prevention program and when follow-up testing should occur.
Can a continuous glucose monitor help you understand your patterns?
A continuous glucose monitor (CGM) records glucose trends throughout the day. For some people, this can make it easier to see how meals, activity, and sleep relate to their readings. However, a CGM does not by itself diagnose insulin resistance, prediabetes, or diabetes.
Stelo by Dexcom is an over-the-counter CGM designed for adults age 18 and older who are not using insulin. It may be useful for eligible adults who want to better understand glucose patterns. It is not intended for people with problematic low blood sugar, and medical decisions should not be made from its readings without professional guidance.
November nutritional support options at DHS
Nutritional supplements may be considered as part of an individualized wellness plan, but they are not substitutes for established diabetes care, a balanced eating pattern, or movement. DHS's November selections have different nutritional purposes.
Gluco-Sugar-Balance for whole-food nutritional support
Gluco-Sugar-Balance combines chromium GTF, vanadium, and whole-food ingredients in a formula marketed for healthy glucose metabolism and nutritional blood sugar support. It may be an option to discuss when reviewing your overall diet and intake of nutrients involved in metabolism.
Berberine HCL for metabolic support
Berberine HCL contains concentrated berberine, a compound found in several plants. Some studies suggest berberine may affect glucose and lipid measures, but the evidence has limitations; it can interact with medicines and is not appropriate during pregnancy or breastfeeding.
Cataplex B for carbohydrate and energy metabolism
Cataplex B is a B-vitamin nutritional supplement that DHS highlights for metabolic, cardiovascular, and nervous system support. B vitamins participate in the body's normal energy-producing processes, including carbohydrate metabolism, but a B-vitamin supplement is not a treatment for insulin resistance.
The right approach may be a food or lifestyle adjustment, a targeted supplement, or no supplement at all. Review any product with your healthcare professional, particularly if you take glucose-lowering medicine or have a chronic condition.
Common questions about insulin resistance
Can you have insulin resistance with a normal A1C?
Yes. Blood glucose can remain within the normal range while the body is compensating by producing more insulin. A normal A1C is reassuring for average glucose but does not directly measure insulin sensitivity.
Does feeling sleepy or craving sweets mean I have insulin resistance?
Not necessarily. Sleepiness and cravings have many possible causes, including sleep habits, meal timing, stress, and other health conditions. If they are persistent or accompanied by other concerns, bring them up with your provider rather than trying to diagnose yourself from symptoms.
Is insulin resistance the same thing as prediabetes?
No. Insulin resistance describes how cells respond to insulin. Prediabetes is defined by blood glucose results that are above normal but below the diabetes range. The two often occur together, but they are not interchangeable terms.
Start with a conversation about your health
If you are concerned about insulin resistance or your risk of type 2 diabetes, begin with your medical history and appropriate blood sugar testing. Bring any previous results, medication and supplement lists, and questions about changes you have noticed.
