What is one sign of hyperglycemia?

Drowsiness and fatigue are indeed classic signs of hyperglycemia, which is a condition characterized by elevated blood glucose levels. When blood sugar levels rise significantly, the body struggles to utilize glucose effectively for energy, leading to a state of fatigue. Additionally, hyperglycemia can cause dehydration due to increased urination, which further contributes to feelings of tiredness and lethargy.

In contrast, other symptoms of hyperglycemia may include excessive thirst, frequent urination, and blurred vision. The other options, while they can indicate other medical conditions, are not typically associated with hyperglycemia. Excessive sweating, shakiness, and confusion are more commonly linked to hypoglycemia, or low blood sugar, while a low heart rate can be associated with various other conditions but does not directly indicate high blood sugar levels. Understanding these signs helps in providing effective care for individuals with diabetes and those on insulin therapy.
