how do i know if im insulin resistant

Insulin resistance cannot be diagnosed based on how one feels; it requires specific blood tests and medical evaluation. Signs that may suggest insulin resistance include a waistline over 40 inches in men or 35 inches in women, blood pressure of 130/80 or higher, fasting glucose levels over 100 mg/dL, high triglycerides, low "good" HDL cholesterol, skin tags, and patches of dark, velvety skin. The main tests to diagnose insulin resistance or related conditions like prediabetes include fasting plasma glucose, oral glucose tolerance test, hemoglobin A1c test, and lipid panel. If these tests show elevated blood sugar or lipid irregularities, insulin resistance may be present. Some symptoms like low energy, excessive sleepiness after eating, frequent hunger, cravings for sugar, irritability, and headaches may also be associated but are not definitive indicators without testing. Screening for insulin resistance is especially recommended for those with risk factors such as family history, obesity, age over 45, or certain ethnic backgrounds. Diagnosis and monitoring require consultation with a healthcare provider and appropriate blood tests.
