Insulin is the hormone that unlocks the cells of the body so that they the sugar from the food facilitate from the blood to there to be used up as the energy. Insulin resistance occurs when body supplies not enough insulin for the body glucose to get converted resulting in the high blood sugar that remains unconverted in the body. There are various medications to cure this case, some related to help the insulin to convert the sugar properly, others working on producing more insulin for the body for the same cause. Insulin resistance is when cells in your muscles, fat, and liver don’t respond well to insulin and can’t use glucose from your blood for energy. To make up for it, your pancreas makes more insulin. Insulin resistance and insulin sensitivity are two sides of the same coin. If you have insulin resistance, you have low insulin sensitivity. Conversely, if you are sensitive to insulin, you have low insulin resistance. While insulin resistance is harmful to your health, insulin sensitivity is beneficial.
