To check for insulin resistance you need to hang up with an endocrinologist. Insulin resistance is the inability of insulin to effectively promote the uptake of glucose by peripheral tissues or to inhibit hepatic glucose output. Common diseases include type 2 diabetes mellitus, hypertension, hyperuricemia, acromegaly, and so on, so you need to hang up with the endocrinology department when checking. Tests related to insulin resistance are fasting plasma insulin concentration, normoglycemic insulin clamp technique, insulin suppression test, glucose tolerance test with simultaneous measurement of insulin release curve, and miniaturization method. Patients with insulin resistance need to be evaluated in detail to make a clear diagnosis. Since there are various means of evaluation and each means has corresponding characteristics, it is recommended that patients choose the most appropriate evaluation method under the guidance of the doctor after consultation.
