Blood sugar, the body's primary fuel source, needs to be kept in check for good health. Unhealthy habits can elevate your blood sugar, leading to prediabetes and type 2 diabetes. If left undetected, it may cause nerve damage, heart disease, and kidney failure. Let's learn about the two most common blood tests used to detect abnormal glucose levels and ways to regulate them properly.

Consider adding the right supplements for you. Go well beyond annual bloodwork with combined insights from your blood, DNA, [Redirect-302] physiomarker, and lifestyle data to optimize your health. What is fasting blood glucose? Fasting blood glucose (FBG) is a test that measures the amount of sugar-glucose-circulating in your bloodstream after you haven't eaten or had anything but water for 8-12 hours. This ensures an accurate baseline reading of your body's ability to regulate blood sugar. Blood sugar levels fluctuate throughout the day, especially after meals. 45-60% of calories come from carbohydrates, Glyco Care supplement which the body breaks down into glucose for fuel. The pancreas releases insulin as the sugar enters the bloodstream. An FBG test shows how efficiently your body manages the breakdown of glucose for fuel. Doctors use it to screen for prediabetes and diabetes, conditions that develop when blood sugar regulation becomes impaired. Healthy glucose levels are associated with better weight control, increased energy, and improved mood and cognition.

High FBG after 8-12 hours without eating indicates an issue with glucose regulation and should be discussed with a physician. What is Hemoglobin A1c? As glucose builds up in the blood, it binds to hemoglobin, a protein found in red blood cells. Because it remains attached throughout its life-90-120 days-HbA1c provides insight into long-term exposure. When FBG levels are high, physicians typically order a hemoglobin A1c-or HbA1c-test to gain insight into someone’s overall health. Unlike FBG ones, which only look at short-term well-being, the HbA1c value reflects the average blood glucose concentration over the past 3-4 months. The higher the glucose level in the bloodstream, the more glucose will attach to hemoglobin; thus, the higher the HbA1c. Note: As a rule of thumb, every 1% change in HbA1c results in an approximate 30 mg/dL change in glucose. What causes HbA1c to increase? Insulin is essential for adequately regulated glucose levels, but several factors interfere with the effect of insulin, either by weakening its signal or making cells less responsive to it.

The accumulation of fat, especially visceral fat-the kind that surrounds our internal organs-directly interferes with insulin signaling. This results in raised blood glucose and HbA1c levels and poses a risk for type 2 diabetes. Note: Maintaining a healthy weight is imperative to well-controlled glucose. Even a 5-10% loss of body mass can significantly improve your levels. Several studies consistently show a link between the consumption of meat and the incidence of type 2 diabetes. A 2015 meta-analysis examined its intake of over 50,000 people. They found that eating processed and unprocessed meat elevated fasting glucose levels. One explanation for this outcome may be due to the high saturated fat content in red meat. High intake increases the risk of developing type 2 diabetes. It could also be due to the high iron content, which interferes with insulin signaling. The majority of Americans do not reach the recommended intake of dietary fiber.
