In which type of diabetes is Hyperglycemic Hyperosmolar Nonketotic (HHNC) coma typically found?

Hyperglycemic Hyperosmolar Nonketotic Coma (HHNC) is primarily associated with Type 2 diabetes. This condition arises due to a significant increase in blood glucose levels, which can lead to severe dehydration and altered mental status, yet does not typically involve the production of ketones.

In Type 2 diabetes, many patients have insulin resistance, which may lead to high blood sugar levels without ketone production. This contrasts with Type 1 diabetes, where there is an absolute deficiency of insulin, commonly leading to diabetic ketoacidosis (DKA) when blood sugar levels rise. Therefore, while both types of diabetes can experience severe complications, HHNC specifically emerges predominantly in those with Type 2 diabetes due to the mechanisms involved in their metabolic state.

Hence, identifying HHNC as a complication predominantly connected to Type 2 diabetes reflects an understanding of the underlying pathophysiology and differentiates it clearly from conditions like DKA, which is more typical of Type 1 diabetes.
