Diabetes Exercise and Activity 3

Question 1

A person with diabetes uses a continuous glucose monitor (CGM). What CGM trend arrow should make them cautious about starting intense exercise?

Accepted Answer

Arrow pointing steeply downward

Answer

A steeply falling CGM arrow indicates rapidly dropping glucose, suggesting that starting intense exercise could accelerate the drop and cause hypoglycemia.

Question 2

Which exercise modification is recommended for people with diabetic peripheral neuropathy affecting the feet?

Accepted Answer

Emphasize non-weight-bearing activities like swimming or cycling

Answer

Non-weight-bearing exercise like swimming or cycling reduces risk of foot injury and ulcers in people with peripheral neuropathy who may not feel pain signals from the feet.

Question 3

A Type 2 diabetic patient on metformin alone starts a new walking program. How does this primarily help their diabetes management?

Accepted Answer

Exercise improves insulin sensitivity in muscle cells

Answer

Physical activity increases GLUT4 transporter activity in skeletal muscle, enhancing insulin sensitivity so muscles take up glucose more efficiently from the bloodstream.

Question 4

What is the primary concern with exercising outdoors in hot weather for people with diabetes?

Accepted Answer

Dehydration can worsen hyperglycemia and impair temperature regulation

Answer

Dehydration concentrates blood glucose and impairs the body's cooling mechanisms; people with diabetes are especially vulnerable to heat-related illness during exercise.

Question 5

Someone with proliferative diabetic retinopathy wants to exercise. Which activity should they AVOID?

Accepted Answer

Heavy weightlifting and Valsalva maneuver activities

Answer

Activities involving straining or the Valsalva maneuver sharply increase intraocular pressure and can cause vitreous hemorrhage in people with proliferative retinopathy.
