Which symptom indicates dehydration?

Which symptom indicates dehydration?

• A. Dark urine with dry mouth.
• B. Clear urine.
• C. Excessive thirst.
• D. Edema.

Answer: (A)

When the body is dehydrated, it conserves water, so the kidneys produce more concentrated urine and you feel dry. Dark urine means the urine is concentrated from reduced fluid intake, while a dry mouth reflects less saliva due to lower overall fluids. This combination is a strong signal that there isn’t enough body water. In contrast, clear urine shows good hydration, excessive thirst can occur but isn’t as definitive on its own, and edema involves excess fluid in tissues rather than a lack of fluids.
