What are the signs of dehydration?

The signs of dehydration are effectively highlighted in the chosen option, which includes dry mouth, dark urine, and decreased skin elasticity.

Dry mouth is a common symptom of dehydration, as the body lacks sufficient fluids to maintain adequate saliva production. This can lead to discomfort and difficulties with swallowing.

Dark urine is another clear indicator, as the body conserves water when dehydrated, leading to more concentrated urine that appears darker in color. Normal hydration typically results in pale yellow urine, so a significant change in color can signal dehydration.

Decreased skin elasticity is a physical indicator that can be tested by gently pinching the skin. When hydrated, the skin quickly returns to its normal position, but if the skin remains tented or takes longer to return, it suggests a lack of fluid in the body.

Understanding these signs is crucial for recognizing dehydration early, especially in vulnerable populations, such as the elderly or those with illnesses. Other options list symptoms that may arise from various conditions but do not specifically align with the classic signs of dehydration.
