What is Insulin Resistance?

What is insulin resistance? Dr. Sonal Chaudry, and endocrinologist, explains what it is and how to avoid developing it.

What is insulin resistance?

Insulin resistance is characterized by the ability to produce insulin, however your cells or your body are unable to effectively use the insulin that's being produced. As a result, in order to maintain normal blood sugar, your body has to produce more insulin. 

As long as your pancreas is able to secrete enough insulin to overcome the peripheral tissue insulin resistance, your blood sugars remain normal. But once the pancreas is no longer able to secrete enough insulin to overcome resistance, that's when prediabetes or Type 2 diabetes and elevated blood sugar develop. 

The major causes of insulin resistance are excess weight and physical inactivity. Excess weight or obesity, especially excess fat around the waist, is a primary cause of insulin resistance. Physical inactivity is also a major contributor because after exercising the muscles become more sensitive to insulin, reversing insulin resistance and lowering blood glucose levels. 

It is incredibly important to eat healthy and stay active in order to avoid developing insulin resistance
