What is a common symptom of hyperglycemia?

Excessive thirst is a common symptom of hyperglycemia, which refers to elevated levels of glucose in the bloodstream. When blood sugar levels rise, the body attempts to eliminate the excess glucose through urine. This leads to increased urination, which can cause dehydration and, consequently, a strong sensation of thirst. Individuals may find themselves drinking more fluids in an effort to compensate for the fluid loss, which can be quite pronounced.

The other choices present symptoms that either do not typically occur with hyperglycemia or do not align with its classic manifestations. For instance, severe fatigue may occur in some contexts but is more characteristic of different conditions, particularly when considering hypoglycemia or other metabolic issues. Increased appetite can also be associated with various states of blood sugar imbalance, but in hyperglycemia, the body’s inability to utilize glucose effectively often leads to a lack of energy, rather than an increase in appetite. Thus, excessive thirst stands out as a well-established and recognizable symptom of hyperglycemia.
