Diabetes Type 1 Diabetes 5

Question 1

Which condition must be distinguished from Type 1 diabetes in a lean adult presenting with hyperglycemia and poor response to oral agents?

Accepted Answer

LADA (Latent Autoimmune Diabetes in Adults)

Answer

LADA is an autoimmune diabetes in adults that progresses slowly and is often misclassified as Type 2; positive GAD antibodies confirm the diagnosis.

Question 2

What is the primary reason patients with Type 1 diabetes must never stop taking insulin, even when not eating?

Accepted Answer

Basal insulin is needed to suppress ketogenesis even without food intake

Answer

Without basal insulin, uncontrolled lipolysis and hepatic ketogenesis occur even in the fasted state, leading to DKA regardless of carbohydrate intake.

Question 3

Which technology continuously monitors interstitial glucose and alerts for predicted hypoglycemia in Type 1 diabetes?

Accepted Answer

Continuous glucose monitor (CGM)

Answer

Continuous glucose monitors (CGMs) measure interstitial glucose every 1–5 minutes and can alert users to impending hypoglycemia or hyperglycemia in real time.

Question 4

What is the 'honeymoon phase' in newly diagnosed Type 1 diabetes?

Accepted Answer

Temporary remission with reduced insulin needs due to residual beta-cell function

Answer

The honeymoon phase is a period of temporary partial remission after diagnosis when remaining beta cells produce enough insulin to reduce exogenous insulin requirements significantly.

Question 5

In a Type 1 diabetic patient, hyperkalemia can develop during DKA primarily because of which mechanism?

Accepted Answer

Insulin deficiency causing potassium to shift out of cells into the bloodstream

Answer

Insulin normally drives potassium into cells; its absence in DKA causes transcellular potassium shift out of cells, raising serum potassium despite total body potassium depletion.
