Absolute insulin deficiency is most typical of which type of diabetes?

Absolute insulin deficiency is a hallmark of autoimmune destruction of pancreatic beta cells, which is what happens in type 1 diabetes. When the immune system targets these cells, insulin production drops to near zero, so the body has no circulating insulin to allow glucose into cells. In gestational diabetes, pregnancy-related hormones cause insulin resistance but insulin is still produced. In type 2 diabetes, there’s insulin resistance with a gradual, often partial reduction in insulin production rather than a complete absence. MODY involves genetic beta-cell dysfunction, but it doesn’t typically present as an abrupt, total lack of insulin. So the scenario described fits type 1 diabetes best.
