Hyperglycemic hyperosmolar nonketotic syndrome (HHNS) is an emergency that the diabetes mellitus (DM) patient may experience. DKA is characterized by hyperglycemia, ketone body formation and metabolic acidosis. We see severe hyperglycemia, leading to glucose being dumped in the urine and causing a hyperosmolar state. In situations of partial/relative insulin deficiency, decreased use of of glucose in fat, muscle, liver leads to increased glucagon secretion. HHS can occur in people with type 1 or type 2 diabetes, but is more common in people with type 2 diabetes. Diabetes: Pathophysiology, Signs/Symptoms, Labs,.

They are both associated with: Insulin deficiency (absolute in T1DM and relative in T2DM) and hyperglycemia Urine output consequently decreases and so less glucose is excreted in urine. The hyperglycemic hyperosmolar state (HHS) is a life-threatening metabolic decompensation of diabetes which presents with severe hyperglycemia and profound dehydration, typically accompanied by alteration in consciousness ranging from lethargy to coma. The hyperosmolar hyperglycemic state (HHS) is characterized by progressive hyperglycemia and hyperosmolarity typically found in a debilitated patient with poorly controlled or undiagnosed type 2 diabetes mellitus, limited access to water, and commonly, a precipitating illness. Glucosuria impairs the concentrating capacity of the kidney, further exacerbating water loss.
