Nonketotic hyperosmolar syndrome, also known as hyperglycaemic, hyperosmolar non-ketotic (HHNK) syndrome,, or hyperglycemic hyperosmolar syndrome (HHS) is an uncommon complication of untreated diabetes mellitus.
Animals with this syndrome need:
- IV rehydration, more so than with diabetic ketoacidosis.
- Replacement therapy for potassium and phosphate losses.
- A slow reduction in their blood glucose levels.
Unfortunately, the prognosis for recovery from the syndrome is poor.
