==Overview==
==Overview==
[Disease name] must be differentiated from other diseases that cause [clinical feature 1], [clinical feature 2], and [clinical feature 3], such as [differential dx1], [differential dx2], and [differential dx3].
The hyperosmolar hyperglycemic state must be differentiated from other conditions presenting with [[hyperglycemia]], [[hyperosmolarity]] or [[Altered mental status|an altered state of consciousness]]. The differentials include [[diabetes mellitus]], [[diabetic ketoacidosis]], [[impaired glucose tolerance]], and conditions causing [[altered sensorium]] such as [[CNS infections]] or [[stroke]]. All these conditions may be differentiated on the basis of history findings, clinical features, and laboratory abnormalities.

* Hyperosmolar hyperglycemic state should also be differentiated from conditions that can cause [[Focal neurologic signs|focal neurological signs]] or an [[Altered mental state|altered state of consciousness]] such as [[CNS infections]] and [[stroke]] by doing a simple [[Glucose test|finger stick glucose testing]].

Overview

The hyperosmolar hyperglycemic state must be differentiated from other conditions presenting with hyperglycemia, hyperosmolarity or an altered state of consciousness. The differentials include diabetes mellitus, diabetic ketoacidosis, impaired glucose tolerance, and conditions causing altered sensorium such as CNS infections or stroke. All these conditions may be differentiated on the basis of history findings, clinical features, and laboratory abnormalities.

Hyperglycemia:

Differentiating hyperosmolar hyperglycemic state from diabetic ketoacidosis (DKA) based on laboratory findings.

Parameters Diabetic ketoacidosis (DKA) Hyperosmolar hyperglycemic state (HHS)
Plasma glucose
  • > 250 mg/dl
  • > 600 mg/dl
Serum osmolality
  • Variable
  • > 320 mOsm/kg
Plasma and urine ketones
  • Positive
  • None or trace
Serum bicarbonate
  • < 18 mEq/L
  • > 15 mEq/ L
Arterial ph
  • < 7.30
  • > 7.30
Anion gap
  • > 12
  • < 12
