A person with type 1 diabetes plans a 90-minute afternoon bike ride. Their pre-exercise glucose is 140 mg/dL. What is the MOST appropriate carbohydrate strategy?
Answer: Consume 15–30 g carbohydrates before and 15 g every 30–45 minutes during exercise
For prolonged aerobic exercise, consuming 15–30 g carbohydrates before and 15 g every 30–45 minutes helps prevent exercise-induced hypoglycemia.
Which phenomenon explains why blood glucose may remain elevated for several hours after high-intensity anaerobic exercise in people with diabetes?
Answer: Catecholamine-mediated glycogenolysis and gluconeogenesis
High-intensity anaerobic exercise triggers catecholamine release, which stimulates hepatic glycogenolysis and gluconeogenesis, causing post-exercise hyperglycemia.
A patient with type 2 diabetes on metformin and a GLP-1 receptor agonist begins a walking program. Which statement about hypoglycemia risk is MOST accurate?
Answer: Metformin and GLP-1 agonists rarely cause hypoglycemia, so exercise poses minimal added risk
Metformin and GLP-1 receptor agonists have low intrinsic hypoglycemia risk, so exercise does not substantially increase hypoglycemia risk in patients on these agents alone.
What is the recommended minimum duration of interruption to prolonged sitting for individuals with type 2 diabetes to improve postprandial glucose levels?
Answer: 3 minutes of light activity every 30 minutes
Breaking prolonged sitting with 3 minutes of light-intensity activity every 30 minutes significantly reduces postprandial glucose in people with type 2 diabetes.
A patient with proliferative diabetic retinopathy asks about safe exercise options. Which activity should be AVOIDED?
Answer: Heavy weightlifting with Valsalva maneuver
Heavy resistance exercise with the Valsalva maneuver causes acute increases in intraocular pressure, risking vitreous hemorrhage in proliferative retinopathy.
Which continuous glucose monitoring (CGM) trend arrow MOST warrants stopping exercise and treating hypoglycemia proactively?
Answer: Glucose 100 mg/dL with a double down arrow
A CGM reading of 100 mg/dL with a double down arrow indicates rapidly falling glucose, posing imminent hypoglycemia risk during exercise.
For a person with type 1 diabetes using an insulin pump, what adjustment is recommended when starting a 60-minute moderate-intensity aerobic session?
Answer: Suspend or reduce basal rate by 50–80% 60–90 minutes before exercise
Reducing or suspending the basal rate 60–90 minutes before aerobic exercise allows time for circulating insulin levels to decrease, reducing hypoglycemia risk.
