HOMA-IR Test – A Test That Can Predict Diabetes

Introduction

The very mention of diabetes can strike fear in the heart of the bravest. It is known to adversely affect several organs in the body, like the eyes, kidneys, nerves, heart and many more. If not diagnosed and treated on time, it can lead to several complications. 

You may have read plenty of blogs on how you can manage diabetes or about the measures you can adopt to prevent the onset of this disorder. But are you aware that there is a test that can predict your chances of developing diabetes? It’s called the HOMA-IR (Homeostatic Model Assessment of Insulin Resistance) test. This test may help you prevent diabetes.

Besides HOMA-IR, several other diagnostic tests are used to diagnose diabetes. Contact your doctor to determine which test is best for you and how to prepare for it. Remember, the earlier the diagnosis, the easier and more effective the treatment will be.

What is Diabetes All About?

To understand how HOMA IR may help you, you have to understand a thing or two about diabetes.

Diabetes is classically understood as two major types– Type 1 (your body produces less insulin) and Type 2 (associated with insulin resistance and less insulin production)². 

Glucose, also known as blood sugar, provides energy to the cells in our body. It acts as fuel, driving our cells, tissues, muscles and organs to perform their respective tasks. Our pancreas produces a hormone called insulin. Insulin sends signals to your cells to pick up glucose from your bloodstream. But sometimes, your cells are unable to process the signals that insulin sends and fail to absorb sugar from the blood. This is a case of insulin resistance. And when this happens, the sugar level in your blood begins to soar. So, we can say that insulin resistance is the precursor to diabetes.  

Abdominal fat increases insulin resistance. Cardio exercises combined with strength training not only decrease insulin resistance(via weight loss) but also increase insulin receptor density in muscles.

Dr. Nikhil Yadav, MBBS MD,CCEBDM

What is HOMA-IR?

Insulin resistance not only paves the way for type 2 diabetes but also other diseases like hypertension, dyslipidemia, cardiovascular disease and cancer.  

Strangely enough, people with normal blood sugar levels may be insulin resistant. And this is exactly where HOMA IR can help. This test measures how resistant your cells are to insulin. Higher Insulin resistance, even if the sugar content in your blood is within acceptable levels, suggests that your blood sugar may spike in the future. This is how the HOMA-IR goes a step further than a normal blood sugar test, which can only monitor your sugar level and cannot detect any issues until high blood sugar develops¹.    

HOMA IR, on the other hand, might ring the warning bells as the resistance to insulin increases in the pre-diabetes stage, so that you can take the necessary steps to prevent a full-blown attack of diabetes.

Acute illness and stress are the two clinically often neglected conditions where the fasting plasma glucose test is more sensitive than HbA1C, which is also known as glycated haemoglobin test, for detecting blood sugar levels. One should always do the Fasting plasma glucose along with HbA1C to get a correct diagnosis.

HOMA-IR Scale

Your results from the HOMA-IR test are displayed against a scale or range that determines the level of your insulin resistance. Low HOMA-IR implies you are sensitive to insulin, and higher levels indicate insulin resistance and a higher chance of you developing diabetes mellitus.  

Ways to Decrease Your HOMA-IR Scale

To properly address the rising insulin resistance in your body, it’s necessary to make changes to your lifestyle and habits. There are two ways in which this could be achieved:

• Dietary changes- Reducing calories and processed carbohydrates and increasing fibre intake.
• Lifestyle changes- Plenty of exercise appropriate for the age and co-existing medical conditions, and activity while avoiding prolonged periods of inactivity².

Initial diagnosis of diabetes should always be made by fasting blood sugar and postprandial blood sugar. For monitoring, you can use HbA1c.

Dr. M.G. Kartheeka, MBBS, MD(Pediatrics)

What Should You Do If You Are Insulin Resistant?

You should consult a doctor who can advise you on appropriate lifestyle modifications or prescribe the right medication. You will also need to follow a special diet of fresh vegetables, fruits, whole grains, fish, eggs, and soy products. Seek a dietician’s help to draw up a diet chart and don’t forget to exercise regularly. Workout is known to decrease insulin resistance. Get at least 7 hours of sleep.    

HOMA-IR is a groundbreaking new method of diagnosing diabetes before it develops. With appropriate care, you can avert diabetes.

Conclusion

It is crucial to understand that diabetes doesn’t develop overnight; it builds silently over time. The HOMA-IR test offers a way to evaluate your risk before the diabetes symptoms even appear. By identifying insulin resistance early, you can take preventive measures such as making lifestyle changes, seeking medical guidance, and developing better habits³. If you or a loved one is at risk, talk to a healthcare professional about whether this test is suitable for you. Take control of your health today, because beating diabetes beforehand is always better than managing it later.
