The Agitated Hypoglycemic Who Refuses Care
A 28-year-old man is brought by police after being found confused and combative on a sidewalk. He is diaphoretic, tremulous, and oriented only to person. Fingerstick glucose is 38 mg/dL. He pulls out an IV and refuses treatment, saying 'I'm fine, leave me alone.' He is pacing, knocking over equipment, and has struck a security guard. There is no obvious trauma. He smells of alcohol. He is 70 kg. The ED is busy; security is present. Family arrives and says he has type 1 diabetes and has been drinking heavily.
1. What is your legal and ethical framework for treating this patient, and how do you proceed?
Read the worked answer
The patient lacks decision-making capacity due to hypoglycemia and altered mentation. Treatment of a life-threatening, rapidly reversible condition is justified under emergency doctrine/implied consent. Proceed with treatment in the least restrictive manner: attempt oral glucose if safe, otherwise parenteral dextrose (e.g., D50 25 g IV or glucagon 1 mg IM if no IV access). Use verbal de-escalation and sufficient staff for safety. Restraint, if needed, must be proportionate, monitored, and documented, and is a bridge to treatment, not punishment. Document capacity assessment and the emergency rationale. The judgment call is acting decisively on a reversible cause while minimizing coercion and risk to staff.
2. After 25 g of dextrose, his glucose is 110 and he is calm and oriented. He wants to leave. How do you handle disposition, and what is your concern?

Reassess capacity now that glucose is normalized; if he is oriented and understands risks, he may have capacity and can refuse further care, but you must address the cause and recurrence risk. Concerns: hypoglycemia recurrence from long-acting insulin, alcohol-induced suppression of gluconeogenesis, and possible missed infection or trauma. Provide a meal, observe for recurrence with repeat glucose, and offer education and follow-up. If he leaves, document capacity, risks discussed, and safety-net instructions. The judgment call is balancing autonomy after reversal against the high risk of recurrent hypoglycemia, especially with alcohol on board.
3. Two hours later he becomes agitated again and his glucose is 45. What does this suggest, and what is your next step?
Read the worked answer
Recurrent hypoglycemia suggests a sustained insulin effect (long-acting insulin), inadequate carbohydrate intake, or an ongoing process such as alcohol-related gluconeogenesis suppression or sepsis/adrenal insufficiency. Next steps: re-treat with dextrose, start a continuous dextrose infusion, give thiamine before or with glucose in a chronic alcohol user, and observe with serial glucose checks. Investigate for infection and check electrolytes. Consider octreotide for sulfonylurea overdose if history suggests it. The judgment call is not to treat and street but to recognize a pattern requiring admission and a monitored infusion.
