What Is Insulin Resistance? Insulin is a hormone made by the pancreas. It helps cells absorb glucose (sugar) from the blood to use as energy. Your body digests foods that contain carbohydrates and releases them as glucose into your blood. Insulin, which is released when you eat, helps the body maintain a healthy level of circulating glucose by allowing glucose from the blood to go into the cells. This lowers blood sugar, and the cells use the glucose for energy. Some people may begin to have problems using insulin correctly. This is referred to as insulin resistance. With insulin resistance, your pancreas produces insulin, but your cells are not using it as well as they should. When insulin is not working the way it should, your cells do…show more content…

Having Type 2 diabetes can also lead to nerve problems that result in tingling sensations in the hands and feet. You may also feel more tired than usual if you have diabetes that is not well controlled. Evidence in Blood Tests Without obvious symptoms, insulin resistance (and, thus, prediabetes and diabetes) is usually detected through a blood draw. One way to diagnose prediabetes or diabetes is with an A1C test. This test provides a number that gives you an idea of how your blood sugar has been averaging over the last two to three months. You don’t need to be fasting for this test. An A1c under 5.6 percent is considered normal. An A1C between 5.7 and 6.4 percent is diagnostic for prediabetes. An A1C equal to or above 6.5 percent is diagnostic for diabetes. Your doctor may choose to confirm this test on another day. In addition to the A1C test, other blood tests can check your blood glucose levels. A fasting blood glucose test — taken after not eating or drinking for at least eight hours — will provide your fasting blood sugar level. A high level may require a second test to confirm this reading a few days later. If two tests show elevated levels of blood glucose in the bloodstream, you may
