Which of the following are symptoms of dehydration?

The symptoms of dehydration include nausea, dizziness, and concentrated urine. Dehydration occurs when the body loses more fluids than it takes in, leading to a lack of sufficient water necessary for normal body functions.

Nausea can arise as the body struggles to maintain its equilibrium without adequate hydration. Dizziness often occurs due to a drop in blood pressure caused by decreased fluid volume in the system. Concentrated urine is a key sign of dehydration, as the kidneys conserve water, resulting in darker and more concentrated urinary output. Recognizing these symptoms is critical in providing timely intervention to prevent the adverse effects of dehydration, particularly in vulnerable populations such as the elderly or those with pre-existing health conditions.
