What Causes Type 2 Diabetes?
We already know that reasons of occurence of diabetes type 1 and diabetes type 2 are different. People with type 1 diabetes are unable to produce insulin and have to inject it every day. But people with type 2 diabetes are producing insulin inside their bodies just fine. The problem is the body does not respond to insulin action. The body can resist to insulin or there is just not enough of it because there is too much body for produced insulin. Pancreas programmed to produce only so much of insulin. If you are 180 pounds of weight it could be enough but if you are 300… do the math. Either problem leads to the same outcome: insulin can’t deliver glucose to the cells that need it, and there is too much glucose in the blood without absorption. Such a waste.
My dear friend, please look to the right and pay attention to my advertisement. I hope you will find useful information on diabetes there or related products and services. Thank you very much!
Let’s go deeper inside the body. Almost all cells in the human body have special proteins called receptors that bind to hormone insulin. They work somewhat akin to a lock and. key. In order for glucose to enter the cell to start produce energy, insulin (the key) musk fit into the insulin receptor (the lock). Sadly, in some people with type 2 diabetes this does not work. The key just does not fit the lock or there just not enough locks to fit in. Those receptors proteins could undergone mutation and don’t accept insulin or insulin by itself could be mutated.
But chiefly the problem is the body pancreas do not produce enough insulin to process all glucose in the bloodstream or by some reason release it very slowly. Without enough insulin to meet the body’s needs, glucose levels rise and diabetes develops. Some scientists believe that the system that controls glucose levels in the blood and tells the pancreas to make more insulin does- not function properly. Other scientists think that the pancreas, after many years of working overtime in obese people, overproducing insulin to combat insulin resistance, simply begin to “burn out”, there are only so much resources.
