Type 2 diabetes is the illness where the hormone insulin produced by your pancreas does not do its job of delivering blood glucose to your organs and muscles and it builds up in the blood stream. That is usually called insulin resistance.
High levels of sugar in the blood causes a gradual impairment in many organs and tissues of the body. Persistent high blood sugar levels result in severe problems called diabetic complications.
When we talk about the type of diabetes we mean the mechanism or the action within the body that causes the symptoms of diabetes. Different “diabetes type” means different “mechanism”.
Since insulin resistance is the main problem Type 2 diabetes is not treated with insulin injections like Type 1. The disease is controlled by diet and drug in tablet form. Some drugs work to reduce insulin resistance while others make the pancreas produce more.
When the blood sugar level rises above a certain level it damages blood vessels throughout your body. The damaged blood vessels is the main cause of the large number of possible diabetic complications. If you can control your diabetes you can prevent the complications.
Exercise is extremely beneficial providing it is at a suitable level for the patient. A sendentary lifestyle is the worst thing for a Type 2 sufferer. A person who has been sedentary can benefit greatly from moderate regular exercise.
So Type 2 Diabetes means the insulin does not work or is prevented from doing its job.
So the next obvious question is What is Type 1 Diabetes?
Confusion with terminology stems from the history of diabetes. Nowadays it is better to use the “Types” of diabetes rather than the older terms which no longer adequately describe the way things are today.
