B Correct answer
Explanation

Air pollution, particularly particulate matter, can decrease insulin sensitivity, leading to impaired blood sugar control and an increased risk of diabetes.

Multiple choice

Which of the following is NOT a potential health risk associated with air pollution and diabetes?

  1. Increased risk of cardiovascular disease

  2. Increased risk of stroke

  3. Improved kidney function

  4. Increased risk of diabetic retinopathy
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Improved kidney function is not a potential health risk associated with air pollution and diabetes. Air pollution is generally associated with an increased risk of cardiovascular disease, stroke, and diabetic retinopathy in individuals with diabetes.

Multiple choice

True or False: Air pollution can exacerbate the symptoms of diabetes, such as fatigue and thirst.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Air pollution can exacerbate the symptoms of diabetes, such as fatigue and thirst, as it can lead to increased inflammation and oxidative stress in the body.

Multiple choice

True or False: Air pollution has been linked to an increased risk of type 1 diabetes.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Air pollution has not been consistently linked to an increased risk of type 1 diabetes. Type 1 diabetes is primarily caused by genetic and autoimmune factors, and the role of air pollution in its development is still unclear.

Multiple choice

True or False: Air pollution can affect the effectiveness of diabetes medications.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Air pollution can affect the effectiveness of diabetes medications, as it can alter the absorption, metabolism, and excretion of these medications, potentially leading to reduced efficacy or increased side effects.

Multiple choice
