Insulin Fasting

Description

Insulin FastingInsulin helps the body's cells use blood sugar for energy. When cells do not respond well to insulin (called insulin resistance), the levels of blood sugar rise. The Insulin, Fasting test checks for abnormal blood sugar metabolism and insulin resistance. These problems are often seen in individuals with diabetes, obesity, metabolic syndrome (includes belly fat, high blood pressure, high blood sugar, and cholesterol levels), and polycystic ovary syndrome (PCOS).The Insulin, Fasting test is usually done with other glucose-related tests, such as fasting blood glucose or oral glucose tolerance tests. The doctor may advise this test following a low blood glucose test result and/or if you have low blood glucose (hypoglycemia) symptoms, such as:Profuse sweatingNervousness or anxietyIrritabilityConfusionDizzinessHungerFast heartbeat, etc.This test can also help detect insulinomas, which are insulin-producing pancreatic tumors.The Insulin, Fasting test is generally safe and well-tolerated. However, you may experience minimal discomfort or bruising at the blood draw site. You must fast for 8-12 hours (only drinking water is permitted). You should inform your doctor about all your medications, as some may impact the test results.
