What is a common sign of hyperglycemia?

In hyperglycemia, which refers to high blood sugar levels, increased thirst is a prominent and common sign. The condition arises because when blood sugar levels are elevated, the body attempts to excrete the excess glucose through the urine. This process can lead to dehydration, prompting the person to feel excessively thirsty as their body signals the need to replenish lost fluids.

While increased hunger, frequent urination, and blurred vision are also symptoms associated with hyperglycemia, increased thirst stands out as a direct result of the dehydration caused by glucose being expelled from the body. When the kidneys filter out the excess sugar, they draw water with it, leading to increased urination and feelings of thirst. Recognizing these signs is crucial for managing diabetes effectively and preventing complications.
