Question

Mark has type 1 diabetes and has mild hyperglycemia. What effect does physical activity (exercise) have on his blood glucose level?

1) It may cause it to vary a little.
2) It may decrease it.
3) It may elevate it.
4) It may fluctuate greatly either way.

Answer 1

If Mark has type 1 diabetes and mild hyperglycemia, physical activity or exercise can help lower blood glucose levels. The correct option is 2) It may decrease it.

Step-by-step explanation:

Physical activity or exercise can benefit blood glucose levels for individuals with type 1 diabetes. When engaging in exercise, the muscles use glucose for energy, which helps to lower blood glucose levels.

However, Mark needs to monitor his blood glucose levels closely before, during, and after exercise to ensure they don't drop too low, which can lead to hypoglycemia. Hence, 2 is the correct option.
