This is referred to as insulin resistance. Sedentary lifestyle is another risk factor. By not exercising, a person tends to lose muscle tissue and gain fat tissue. As above, this leads to insulin resistance. A high-carbohydrate diet is a risk factor, too.
Carbohydrates are molecules that are short to long chains of sugar molecules.
The body digests and converts these to glucose very quickly. Carbohydrates are the mainstay of many diets and are found in bread, pasta, rice, potatoes and simple sugars such as table sugar. Type II diabetes is treated in several ways. As you may have guessed from the list of risk factors, lifestyle modification is important. Losing weight, exercising and modifying the diet are all important elements to help control diabetes.
