Which symptom is NOT typically associated with high blood sugar levels?

High blood sugar levels, or hyperglycemia, are commonly associated with a range of symptoms such as frequent urination, excessive thirst, and extreme fatigue. These symptoms occur because the body attempts to eliminate excess sugar through urination, which leads to dehydration and increased thirst. Additionally, when cells do not receive adequate glucose for energy due to insulin resistance or insufficient insulin, fatigue can result.

In contrast, increased night vision does not correlate with high blood sugar levels. This symptom is more aligned with low light conditions or specific eye health issues and is not a recognized symptom of hyperglycemia. Therefore, the option related to increased night vision is not typically associated with high blood sugar levels, making it the correct choice in this context.
