Understanding Blood Sugar Test Results

Today we are going to explore what certain test results really mean about your health and what you can do if you have levels of high sensitivity C-reactive protein (hsCRP), hemoglobin A1C (HbaA1c), fasting blood sugar, fasting insulin, post-meal glucose, and homeostatic model assessment for insulin resistance (HOMA-IR).
It is just important that you are able to make sense of your lab results and know why the optimal, not just the standard range matters. As I have mentioned before, an illness may already be present even when the lab tests have standard results. 

But before digging into the above mentioned metabolic markers, let’s understand the basics of diabesity first: diabetes and obesity together. There are two types of diabetes: Type 1 and Type 2. Both of them make the sugar levels high, but they do so in different ways.
After a meal, our blood glucose elevates and triggers the pancreas to produce insulin. Insulin is the only way for the glucose to enter the cells, so without insulin, glucose in the blood remains high, which is not good because it can cause health problems.
In type 1 diabetes, your body’s own immune system attacks the cells in the pancreas that produce insulin. So the pancreas stops producing insulin and blood sugar level increases, which is very dangerous and even deadly if not addressed.
In type 2 diabetes, your pancreas still produces insulin but your body doesn’t respond to it as it should. Less glucose enters the cells and your blood sugar level remains high. This is called insulin resistance. In response, your pancreas works even harder to produce more insulin, putting a strain on the organ, and eventually leading to greater malfunction.
Now let’s understand where metabolic markers in blood tests play a role in diabesity.

High Sensitivity C-reactive protein (hsCRP)

The liver creates hsCRP and when there is inflammation, this protein becomes elevated in your blood. We know that inflammation is an indicator of metabolic dysfunction. The higher the result, the more inflammation there is in your body. People with chronic inflammation, including those with obesity, diabetes, Alzheimer’s disease, leaky gut, cardiac-related inflammation and cancer have high hsCRP.
A result of more than 2 mg/dl means you have a higher risk for cardiac disease while lower than that means you’re less at risk. However, for optimal results, 0.5 mg/dl or lower is best.

Hemoglobin A1C (HbaA1c)

This is a way to assess blood glucose averages over the preceding three months, since glucose molecules attach to the hemoglobin of red blood cells which tend to live for about three months. This process is known as glycation.
Your HbaA1c can tell you if your blood glucose levels have been high over a period of time. So even when you have a normal fasting blood sugar level, your HbaA1c can be high and this will give you the idea of what is really going on in your body. This used to be done only to monitor diabetics, but it can diagnose prediabetes and diabetes. The standard value considered to be normal is less than 5.7%. More than that is considered prediabetes (5.7%-6.4%) and diabetes (>6.5%)

Fasting Blood Sugar

This measures the blood glucose levels without being affected by a recent meal. You have to typically fast for about 8-12 hours before the test.
Blood sugar matters. When it is chronically high, it can damage your blood vessels and nerves and affects your vital organs.
Below 100 mg/dl is considered normal but optimal is below 90 mg/dl (some experts even say below 85 is ideal). Higher than 100 mg/dl is indicative of prediabetes (100-125 mg/dl) or diabetes (126 mg/dl).

Fasting Insulin

This measures insulin levels without being affected by a recent meal. The pancreas is designed to produce insulin in response to the high blood glucose levels. It works just to maintain the normal blood glucose levels, so getting fasting insulin will give you a sense of how hard your pancreas is working to keep your blood glucose down.
The normal range is below 25 mIU/L. This means you have strong insulin resistance. Shoot for the optimal levels, which is lower than 8 mIU/L.

Post-Meal Glucose

This test measures your blood sugar levels two hours after a meal. Not every metabolic dysfunction can be diagnosed through a fasting glucose test, so it’s valuable to check postprandial (after meal) glucose as well. A spike in blood glucose after eating can cause atherosclerosis and damage the walls of your blood vessels. So if the glucose spikes become chronic, you are at a high risk of developing cardiovascular disease.
The standard range is less than 140 mg/dl, but the optimal level is below 120 mg/dl.

Homeostatic Model Assessment for Insulin Resistance (HOMA-IR)

This indirectly measures how your body’s insulin is working in dealing with glucose using the following equation:
(Score) = (Fasting insulin) x (Fasting glucose) / 405
When you have the results for fasting insulin and fasting glucose, then you’ll be able to identify your HOMA-IR. A healthy range is between 0.5 and 1.4, but aim for less than 0.5 for optimal results. Lower results mean you are insulin sensitive (which is what you want!). You only require a little insulin to lower your blood glucose levels. Higher results, on the other hand, mean you are insulin resistant and your body doesn’t respond well to the effect of insulin so your cells don’t take the glucose from your blood.
I hope this will help you better understand your metabolic health markers and your overall health status as well.

Your diet and lifestyle hugely influence metabolic markers! Eating a clean diet rich in high quality protein and plants, healthy fats, drinking plenty of water, getting 7+ hours of sleep each night, moving your body daily, and managing your stress throughout the day are the foundations to good health.
