There is a decrease in the water content in cells, amount of fluid circulation, amount of bone, and function of internal organs at an older age. These factors tend to cause frailty. The amount of water in the body in older people is also greatly affected by the degree of individual mental and physical disorders, such as chronic illness, visceral function, decreased swallowing function, loss of appetite, dementia, and depression.
