Insulin is a hormone produced by the pancreas which helps glucose, or blood sugar, make its way into cells throughout the body’s muscle, fat, and liver to be used for energy. Glucose is found in various amounts in different types of food. Blood sugar levels spike after you eat, prompting the pancreas to release insulin. Thereafter, insulin regulates blood sugar levels.
When the cells in your body no longer respond to insulin as they should, it impedes their ability to take glucose from the blood. As a result, glucose builds up in the blood. The pancreas goes into overdrive, producing even more insulin in response. This phenomenon is known as insulin resistance.
Insulin sensitivity is one of the most important markers of overall wellness. Insulin resistance is the hallmark of type 2 diabetes and is ultimately associated with the cascade of events that can cause metabolic syndrome, a cluster of disorders that increase the risk for stroke and heart disease, as well as premature cardiovascular-related deaths. 
Here, we take a closer look at insulin resistance to help you determine your risk and actively prevent against this serious condition. Additionally, patients who have already been diagnosed with insulin resistance will find treatment options below.
