Which of the following are signs of hyperglycemia?

Increased urination and weight loss are indeed signs of hyperglycemia, which is a condition characterized by elevated blood glucose levels. When the body cannot effectively utilize glucose due to insufficient insulin or insulin resistance, it leads to an accumulation of glucose in the bloodstream. As a result, the kidneys begin to excrete excess glucose through urine, causing increased urination, also known as polyuria.

Additionally, the loss of glucose through urine means the body is losing calories, which can lead to weight loss, despite normal or increased appetite. This unintended weight loss occurs because the body is breaking down fat and muscle for energy instead of using glucose adequately.

In contrast, decreased urination and thirst are often associated with dehydration, which can occur in other conditions. Fatigue and anxiety may be general symptoms in various medical situations, while blurred vision is a symptom of fluctuating glucose levels, but fever is associated with infection rather than hyperglycemia specifically. Understanding the link between glucose metabolism and these physical symptoms is crucial for recognizing and addressing hyperglycemia.
