Chronic diseases are long-term illnesses that require continuous management. Most of these diseases are age-related and are a result of changes that occur as people age. However, the relationship between normal aging and chronic disease is more complex than you might think. If you think about the relationship between normal aging and chronic disease, you will find that there are many factors that can increase your risk of chronic disease.
Normal aging causes a decrease in total body water
Decreased total body water is a common problem among older adults. The decrease in water volume is a result of a combination of physiological changes and chronic disease. A decrease in total body water can cause several problems, including decreased cognitive function. Chronic disease and aging may also affect the immune system, which can lead to an increased risk of infection and delayed recovery from illness. Aging also affects the hematologic system, reducing blood volume and reducing bone marrow mass. Consequently, aging may increase the incidence of blood disorders.
The decrease in total body water can cause impairment in cognitive function, impaired blood flow to the brain, and impaired metabolism. It may also be associated with systemic inflammation. In addition, the aging process is associated with subtle changes in muscle atrophy and renal function.
