Changes You Can Expect through the Aging Process

Our bodies change inevitably as we age, changing in many ways that affect the function of both individual cells and organ systems.

These changes happen slowly yet progressively over time. However, the rate of this progression can vary from person to person. Research in aging is beginning to find out these changes and the factors that control them.

Aging of cells

As we grow old, our cells change in function. For instance, the rate at which cells multiply tends to slow down as we age. Certain cells important for our immune system also decrease with age.

In addition, these cellular changes are responses to environmental stresses or exposures like ultraviolet light, heat, lack of oxygen, poor nutrition, and toxins among others.

Physical changes

Our bodies normally change in appearance as we age. We begin to lose height once we reach our late forties for up to two inches by age 80. This is due to changes in posture and vertebrae growth, compression of the discs between the vertebrae, decreased joint space, increased curvature of the hips and knees, flattening of the arches, etc.

We also experience increased body weight until mid-fifties, which then decreasing until the late sixties and seventies, as well as an increase in body fat percentage due to decrease in muscle mass.

Changes in the regulation of body systems

The way our body regulates certain systems changes with age. Your body would have less control on its blood pressure, could not regulate its temperature normally, has decreased amount of body fluids, among others.

These are caused by natural and external causes such as cigarette smoking, low nutritional intake, stress, etc.
