Hyperinsulinemia is the medical term used for increased levels of insulin in the blood. This condition commonly occurs in people with metabolic syndrome like obesity, faulty lipid levels, and other associated factors. Insulin augments fat storage and enhances appetite that is why people with hyperinsulinemia are prone to weight gain and obesity.
Insulin is a hormone which plays an important role in carbohydrate and fat metabolism. People taking insulin noticed that they gained weight. Experts say that it is a common effect of insulin because glucose absorption is enhanced ― giving the cells more glucose than what is required. Since there is too much glucose in the cells, the unused amounts accumulate as body fat thus causing weight gain. In addition, the hormone stops fat breakdown and also promotes glucose uptake into fat tissues resulting to more weight gain.
