Insulin Resistance Test

Insulin resistance (IR) is a condition characterised by resistance to the effects of insulin at a cellular level. It is usually measured by the HOMA-IR score. We offer detailed testing to uncover if blood sugar regulation is functioning optimally.

What is Insulin Resistance?

Insulin resistance (IR) is a condition characterised by resistance to the effects of insulin at a cellular level. Muscle, liver and adipose tissue require increasingly greater amounts of insulin to transfer sugars from the bloodstream. When the body's cells ignore the extra insulin made by the pancreas, this results in high glucose AND high insulin levels in the bloodstream. Untreated insulin resistance may lead to Type 2 Diabetes and require medical intervention and ongoing treatment.

How To Test For Insulin Resistance

Insulin Resistance is calculated from both the fasting insulin and fasting glucose results to create the HOMA-IR score (homoeostasis model assessment of insulin resistance). The HOMA-IR score can be used to identify subtle insulin resistance, even before it is evident in more traditional screening measures like Haemoglobin A1c (HbA1c) and fasting blood glucose.

The symptoms for insulin resistance include characteristics such as:

weight gain,
fatigue,
cravings,
irritability,
depression,
poor concentration and memory.

In addition, Insulin Resistance is a key component of the Metabolic Syndrome along with abdominal obesity, elevated LDL cholesterol and triglyceride levels, low HDL cholesterol and high blood pressure.

A strong family history of diabetes is a major risk factor for high levels of insulin resistance, along with high GI carbohydrates intake including excessive alcohol consumption; lack of regular exercise; stress and nutritional deficiencies such as chromium, vanadium and magnesium.

How Can We Diagnose and Treat Insulin Resistance?

Our practitioners have seen hundreds of patients presenting with symptoms of Insulin Resistance. Very often they have had the standard Fasting Glucose or HbA1c test which has come back within the normal range. This is not enough information for us to truly understand if blood sugar regulation is functioning optimally. There are additional tests that are available to us, the most common one we request includes Fasting Glucose and Fasting Insulin which is used to calculate the HOMA-IR score. These tests give us a much better idea as to how well blood sugar regulation is functioning at a cellular level.

FAQs About Insulin Resistance Testing

What is insulin resistance?

Insulin resistance is a condition where the body’s cells become less responsive to insulin, the hormone that helps move glucose from the bloodstream into the cells for energy. When this happens, the body may produce more insulin to help keep blood sugar levels stable. Over time, insulin resistance can affect metabolic health and may increase the risk of developing prediabetes and type 2 diabetes.

What causes insulin resistance?

Insulin resistance can develop for a range of reasons and is often influenced by a combination of factors. Common contributors include poor diet, low physical activity, excess body fat, chronic stress, poor sleep, hormonal imbalances and genetic predisposition. In many cases, it develops gradually and may go unnoticed in the early stages.

What is the HOMA-IR test?

HOMA-IR stands for Homeostatic Model Assessment of Insulin Resistance. It is a calculated marker based on fasting glucose and fasting insulin levels, used to estimate how the body is responding to insulin. It can be a useful tool for identifying signs of insulin resistance and assessing early metabolic imbalance.

What is the difference between HOMA-IR and HbA1c?

HOMA-IR and HbA1c measure different aspects of blood sugar health. HOMA-IR is used to estimate insulin resistance based on fasting insulin and fasting glucose levels. HbA1c measures average blood glucose levels over the previous two to three months. In simple terms, HOMA-IR helps assess how well the body is responding to insulin, while HbA1c provides a longer-term picture of blood sugar control.

What are the early warning signs of insulin resistance?

Early warning signs of insulin resistance can include increased hunger, sugar cravings, fatigue after meals, brain fog, difficulty losing weight and weight gain around the abdomen. Some people may also notice energy fluctuations or skin changes such as darker patches around the neck or underarms. However, insulin resistance can also be present without obvious symptoms, which is why testing may be helpful when risk factors are present.

Can insulin resistance be reversed?

In many cases, insulin resistance can be improved with the right support and lifestyle changes. A personalised approach may include dietary changes, regular exercise, better sleep, stress management and support for any underlying hormonal or metabolic imbalances. Early identification can be helpful in guiding appropriate steps before blood sugar issues become more advanced.
