Overview

What is Insulin Resistance?

Insulin is a hormone made by your pancreas. Its main role is to regulate the amount of nutrients circulating in your bloodstream. Although insulin is mostly implicated in blood glucose management, it also affects fat and protein metabolism.

Insulin resistance is the condition in which cells stop responding to insulin correctly, which causes the pancreas to produce even more insulin to lower your blood glucose levels. This leads to high insulin levels in your blood, a condition called hyperinsulinemia.

Although this condition is more common among those with excess weight, people with low or normal weight are also susceptible. Other causes of insulin resistance include:
