This is known as insulin-dependent diabetes mellitus (IDDM). This type ofdiabetes includes people who are dependant on injections of insulin on a daily basis inorder to satisfy the bodies insulin needs, they cannot survive without these injections.OVERVIEW OF DIABETES TYPE IWhat is diabetes type I?In order to understand the disease we firstly need to know about insulin. Insulin is ahormone. The role of insulin is to convert the food we eat into various useful substances,discarding everything that is wasteful.It is the job of insulin to see that the useful substances are put to best use for ourwell-being.
