Hypoglycemia

ABCs

  • Confirm random blood glucose < 4 mmol/L
  • Assess level of consciousness and hydration status

HPI

  • Autonomic symptoms: sweating, palpitations, nausea, vomiting
  • Neuroglycopenic signs: confusion, neurological deficits, altered mental status
  • Review:
    • Diabetes history, insulin regimen, and adherence
    • Nutritional intake and recent fasting or NPO status

MANAGEMENT

  • If unconscious or confused:
    • Call for assistance
    • If IV access available → Give 50 mL of 50% dextrose IV
    • If no IV access → Give Glucagon 1 mg IM/SC and establish IV access
    • Recheck glucose in 10–15 minutes → If < 3.5 mmol/L, repeat treatment
  • If conscious, alert, oriented:
    • Give orange juice, glucose tablets, or a spoon of honey
    • Recheck in 10–15 minutes → If still < 3.5 mmol/L, repeat oral intake or give IV dextrose

POST MANAGEMENT

  • Look for underlying cause
    • Acute illness?
    • New meds (e.g., insulin, sulfonylureas)
    • Hold short-acting insulin or any contributing hypoglycemic agent
  • Monitor capillary glucose q30min for 2 hours

ESCALATION

  • If glucose remains < 3.5 mmol/L or if recurrent episodes
    Call for assistance
    → Consider starting a dextrose infusion
    → Evaluate for ICU transfer if unstable or altered LOC
