In addition to these general outward symptoms of diabetes, there are very spicific events that are happening inside the body. The effects on the body in the case of Type 1 Diabetes and Type 2 Diabetes differ somewhat. In the case of Type 1 Diabetes, the body simply makes no insulin, or at least not enough to be effective in any way. This is what makes people with Type 1 Diabetes insulin dependent. In the case of Type 2 Diabetes, however, the body may make a sufficient amount of insulin, but the body is resistant to the insulin it produces.
