Diabeties Diets - For Life Improvement Basically, there are two types of diabetes, 1 and 2. Type 1 is much less common than Type 2, and occurs before the age of 40.
Type 1 is associated with a lack of insulin, and without enough insulin you cannot maintain a normal blood glucose level. This in turn causes hyperglycemia, or an overabundance of sugar in the blood. This is a dangerous condition.
