Which of the following is a common symptom of diabetes?

Increased thirst is a hallmark symptom of diabetes, specifically due to the way the condition affects the body's ability to process glucose. When blood sugar levels rise (a condition known as hyperglycemia), the kidneys work harder to filter and absorb the excess glucose. As a result, excess glucose is excreted in the urine, which leads to increased urination. This process causes the body to lose a significant amount of water, resulting in dehydration. Consequently, individuals with diabetes may experience intense thirst as their bodies signal the need to replenish lost fluids.

This symptom is often accompanied by others, such as increased urination and fatigue, but increased thirst stands out due to its direct relationship with dehydration resulting from the body's attempts to manage high glucose levels. Understanding this relationship can help in recognizing the onset of diabetes and the importance of managing blood sugar levels effectively.
