Which symptom is most likely caused by hyperglycemia?

1. Fever and orthostatic hypotension

2. Increased urination

3. Diarrhea

4. Chest pain

The correct answer is: Fever and orthostatic hypotension

The symptom most commonly associated with hyperglycemia is increased urination, also known as polyuria. When blood glucose levels rise significantly, the kidneys filter out excess glucose into the urine. This process draws more water into the urine, leading to increased urination. In the context of hyperglycemia, other symptoms may also present, such as increased thirst, fatigue, blurred vision, and headaches. While fever and orthostatic hypotension may indicate other conditions, they are not directly caused by high blood sugar levels. Likewise, diarrhea and chest pain may arise from various medical issues that are not specifically related to hyperglycemia. Thus, increased urination is the hallmark symptom directly linked to elevated glucose levels in the bloodstream.
