the diet Health implications of too much sugar! Type 1 Diabetes Type 1 diabetes is a long-term disease occurring in the pancreas in which very little or no insulin is produced; the hormones that are needed to convert sugar in our bodies to energy. Type 1 is usually developed in the early childhood stages. Type 2 Diabetes Type 2 is known as the adulthood non insulin depending type of diabetes. Type 2 is preventable, but the condition is not. When diagnosed with type 2 diabetes, the body is resisting insulin. Type 2 diabetes can also lead to other health problems like heart disease, kidney disease, stroke, blindness, becoming overweight, and death! According to research, Type 2 Diabetes is only developed if, and only if, Pre-Diabetic symptoms are ignored.
