What is a common symptom of dehydration?

• A. Rapid heart rate
• B. Dark urine
• C. Constipation
• D. Excessive sweating

Answer: (B)

Dark urine is commonly recognized as a symptom of dehydration. When the body is not adequately hydrated, the kidneys conserve water leading to concentrated urine, which results in a darker color. Normal healthy urine is typically light yellow, and any noticeable shift towards a darker shade often indicates that the body might be experiencing a fluid deficit.

While rapid heart rate, constipation, and excessive sweating can also be associated with dehydration, they are not as direct or specific a signal as dark urine. Rapid heart rate could be influenced by many factors, including stress or exercise; constipation can be affected by various dietary factors and is not solely a result of dehydration; excessive sweating is usually a response to heat or exertion, which may actually lead to dehydration but does not serve as a definitive indicator of it. The clarity and color of urine provide a straightforward assessment of hydration status, making dark urine a key sign of dehydration.
