What are common symptoms of hyperglycemia?

Polyuria and polydipsia are hallmark symptoms of hyperglycemia, which is a condition characterized by elevated levels of glucose in the blood, often seen in individuals with diabetes. When blood sugar levels are high, the kidneys attempt to excrete the excess glucose through urine, leading to increased urination (polyuria). This loss of fluid can result in increased thirst (polydipsia) as the body seeks to replenish lost fluids. Together, these symptoms indicate the body’s way of trying to manage high glucose levels and prevent potential complications related to hyperglycemia.

In contrast, shaking and sweating are more typically associated with hypoglycemia, or low blood sugar. Headache and fatigue can occur in both conditions, but they are not specific indicators. Blurred vision can occur in hyperglycemia, but chills are not a typical symptom associated with this condition.
