Insulin resistance cannot be self-tested and requires medical examination to confirm the diagnosis. Insulin resistance refers to a decrease in the body’s sensitivity to insulin, which is mostly related to the patient’s genetics, environment and other factors, and usually does not exist alone, but often co-exists with other metabolic diseases. Due to the decreased sensitivity of patients to insulin, the insulin in the body can’t work properly, insulin can’t promote the uptake of glucose by the tissue cells normally and can’t inhibit the output of glycogen from the liver to the outside, these processes can’t be detected through the patient’s own checkups, so insulin resistance can’t be diagnosed by the patient’s self-tests. Generally speaking, the most ideal and accurate method to confirm the diagnosis of insulin resistance is glucose clamp test, but due to the technical means and operation methods, it is difficult to operate in the clinic; commonly used measurement methods include fasting plasma insulin concentration, insulin release test, etc. The specific choice should be made by specialized physicians. The specific choice of method should be determined by a specialized physician, which can accurately assess whether the patient has insulin resistance, and is conducive to subsequent treatment.
