A 28-year-old female patient is found to be responsive to verbal stimuli only. Recent type 1 diabetes with excessive urination and worsening over 24-36 hours. On the basis of this presentation, you should suspect that she:

• A. Is hypoglycemic.
• B. Is significantly hyperglycemic.
• C. Is infected with a new illness.
• D. Is dehydrated due to water loss.

Answer: (B)

When a person with type 1 diabetes shows polyuria and a gradual worsening of mental status over a day or two, the most likely situation is very high blood glucose with an osmotic diuresis driving dehydration. Glucose spilling into the urine pulls water with it, so excessive urination is a direct clue to hyperglycemia. As glucose climbs, brain function can deteriorate, leading to decreased responsiveness, which matches being alert only to verbal stimuli. This pattern fits a hyperglycemic crisis (and often a diabetic ketoacidosis picture) far better than hypoglycemia, which typically presents with sudden sweating, tremors, and agitation rather than a progressive dehydration over 24–36 hours. Infection could trigger or worsen hyperglycemia, but the core inference from the signs is that she is significantly hyperglycemic.
