Which type of diabetes is characterized by the absence of insulin production?

The absence of insulin production is a hallmark of Type 1 diabetes. This condition arises when the immune system mistakenly attacks and destroys the insulin-producing beta cells of the pancreas. Individuals with Type 1 diabetes experience a significant deficiency of insulin from the onset of the disease, necessitating insulin therapy for blood sugar regulation.

Type 2 diabetes, on the other hand, is primarily characterized by insulin resistance, where the body is unable to effectively use the insulin that is produced. Although individuals with Type 2 diabetes may eventually require insulin therapy, especially as the disease progresses, they typically still produce some insulin during the early stages. Pre-diabetes refers to a condition where blood glucose levels are higher than normal but not high enough to be classified as diabetes.

Thus, the clear distinction lies in the complete lack of insulin production in Type 1 diabetes compared to the other forms of diabetes.
