Dehydration in the elderly often presents with subtle and atypical features due to age-related physiological changes and coexisting illnesses. Thirst perception is diminished, so older adults may not complain of thirst even in significant fluid deficit. Common early symptoms include dry mouth, dry tongue, cracked lips, and reduced skin turgor, although skin elasticity is less reliable in advanced age. Sunken eyes and decreased sweating may also be observed. General symptoms include weakness, fatigue, dizziness, and lethargy. Postural hypotension is common, leading to lightheadedness
