Loss of appetite associated with the aging process.
Aging typically leads to a gradual decline in glomerular filtration rate (GFR) due to changes in kidney structure and function. This decline is a normal part of aging and is often associated with a decrease in the number of functioning nephrons and reduced renal blood flow. This reduction in GFR can contribute to age-related kidney diseases and changes in medication dosages in older adults.
Some signs that the cardiovascular system is aging are increased stiffness of the aorta, reduction in the cardiac muscle fiber size, progressive loss of cardiac muscular strength, reduced cardiac output, a decline in maximum heart rate, and an increase in systolic blood pressure.
Lack of physical activity
Maturing and aging.
A declining population size can lead to labor shortages, reduced economic growth, increased healthcare costs for an aging population, and a strain on social welfare systems. It can also result in a smaller consumer base, which may impact businesses and overall productivity in a country.
