To understand insulin resistance, helps to understand a little about how insulin works and its function in the body. Insulin is an essential hormone created in the pancreas, which is involved in the metabolism of sugars in the body. Without it, we can not convert the food we eat into usable energy. When we eat something, much of digested food is converted into glucose, the body’s main energy source. The pancreas then responds to increasing blood sugar levels by secreting insulin in the blood stream. Most of the cells in your body contain receptors of insulin that help tie the insulin to the cell.

Once insulin is attached to the cell, activates other sites of the receptor, which allows glucose is incorporated into the cell and provide energy for life. Insulin also plays other vital body roles such as storing excess foods and magnesium, sodium retention and management of other hormones in the body including growth hormones, the testosterone and progesterone. Insulin is also responsible for stopping the liver of launching fat, a potential metabolic fuel, in the blood after a meal. Insulin resistance occurs when while the body produces insufficient amounts of insulin, the cells in the body become resistant to its effects. When this happens, the body requires more than the normal amount of insulin to have effect, and as a result, the pancreas produces more insulin. While the pancreas can continue with the high demands of insulin, blood sugar levels remain normal, however, increased levels of insulin may have other health effects negatives such as weight gain, high blood pressure, osteoporosis, disease, fatty liver and hormone-related conditions such as polycystic ovarian syndrome (PCOS). If the pancreas cannot continue with the demands of the insulin, can ocurrit type II diabetes. Diagnosis of diagnosis insulin resistance of the insulin resistance is not based only on the insulin levels, but includes a very careful medical history and a physical examination.
