What is a common symptom of dehydration?

Dark yellow urine is a common symptom of dehydration, as it indicates a concentration of waste in the urine due to a lack of sufficient fluids in the body. When the body is dehydrated, it tries to conserve water, leading to less diluted urine that appears darker in color. This coloration acts as a visual cue for individuals to recognize that they may need to increase their fluid intake.

In contrast, increased energy levels are generally not associated with dehydration; rather, dehydration often leads to fatigue. Frequent urination usually occurs when fluid intake is high or when certain medical conditions exist, while regular appetite is often not affected by dehydration; in fact, it can diminish due to feelings of nausea or low energy associated with a lack of adequate hydration.
