Water is very essential as it stimulates peristalsis and thus aids in combating constipation. The kidneys also need fluid to dispose waste more effectively.
Some elderly individuals have a fading sense of thirst and go for longer periods without water. Others avoid drinking enough water for the fear of incontinence. This may lead to dehydration that in turn can give rise to confusion, headache, and instability.
Dehydration is a risk for the elderly who do not notice their thirst or avoid drinking water as it leads to the necessity of passing urine.
Total body water decreases with age. So, even slight fever or hot weather can precipitate rapid dehydration.
Dehydration makes them more susceptible to urinary tract infections, pneumonia, pressure ulcers, confusion and disorientation. An intake of 6-8 glasses of water is recommended. Water can be consumed as such or in form of buttermilk, soups, and juices.
Beverages containing alcohol or caffeine cannot replace this intake as they have a diuretic effect.
