Type 1 Diabetes

Type 1 diabetes occurs when the body stops producing insulin in the pancreas. The pancreas lies at the back of the abdomen and has two main functions: to produce a juice that flows into the digestive system to help us digest food to produce the hormone called insulin. Insulin is the key hormone that controls the flow of glucose (sugar) in and out of the cells of the body. Type 1 diabetes is caused by a lack of insulin output because of auto-immune damage to the pancreas gland. Damage to the pancreas can occur for a many reasons, eg a viral infection. But the most common cause in type 1 diabetes is the body's own immune system. Insulin-producing cells in the pancreas of people with type 1 diabetes are destroyed by cells that normally defend us from invading organisms. This is called an 'auto-immune' process, referring to the fact the body appears to turn against itself. The reason why this happens in unknown. Term watch Type 1 diabetes used to be called 'insulin dependent diabetes'. This is because this type of diabetes always requires insulin treatment. As some people with type 2 diabetes now also require insulin, the term type 1 is preferred. There are other auto-immune diseases, Continue reading >>

    Welcome Mike to DD. Lack of insulin or insulin insufficiency can be tested by a C Peptide test. Insulin resistance can also be tested with a C Peptide. If you have a high level of insulin and high fasting numbers you probably are insulin resistant. A very low number may indicate lack of insulin. Once your beta cells are damaged they usually don't regenerate and you will probably need injected insulin.

    From what I've read, a lot of doctors don't make the distinction between IR and insulin insufficiency. To my doctor, high blood sugar is the issue...WHY it's high is irrelevant. He started going down his list of medications, starting with Metformin. If it didn't work, he'd shrug and try the next drug on the list. I had to beg him to do tests (except lipids...he was crazy for lipid tests, even though mine were good every time). I want answers, so I wasn't happy with that. Seems to me you'd want to know WHY it's high to determine the best treatment.
