Water Intake for Older Adults
Explore thirst, access to drinks, medicines, and health conditions that can affect hydration in older adults.
Daily routines may change with age

Make fluids easier to reach
Keeping a cup nearby, serving drinks with meals, and choosing tolerated options such as water, milk, or broth can help with access. These practical ideas are not a substitute for advice about swallowing difficulty, heart or kidney disease, medication effects, or a prescribed fluid limit.
Watch for changes, not just a number
