What are the changes that occur in our body with the increase of age?

Human life is marked by three stages of changes marked as birth, growth, and death which happen over a period of 0 to 100 years. The human body experiences and undergoes many physical and physiological changes during this period. Some changes are apparent and some are inherent. Some changes cause discomfort to the person while others simply change your external appearance.

External changes

The human body is prone to change as per law of nature. Depending on how one nurtures, nourishes and keeps it active decides the agility and health of the person and how long he will live. The apparent changes that one can observe are:

  • Teeth will decay and fall.

  • Hair becomes thin, turns gray and falls.

  • Fat loss occurs.

  • Skin wrinkles.

  • Due to the changes in posture or vertebral changes, decreased space in joints and increased curvature of hips and knees people get haunch back.

  • The weakening of the body occurs and more prone to diseases.

  • Stamina decreases and agility decreases.

Internal changes

The human body undergoes changes internally too with added age. Some of the common changes would be:

  • Decreased functioning of internal organs like kidneys and liver.

  • Body muscle mass decreases.

  • Bone density and viscera reduces and bones become more porous.

  • Hormonal changes occur.

  • Cartilage between joints like knees and hips reduces and lubrication decreases causing stiffness of joints and slowed movements.

  • Skull thickens with age.

  • Ageing causes important changes in tissue structure and body composition.

  • Tissue loss occurs over age and this reduces the amount of water in the body.

  • Skin flattens due to loss of subcutaneous fat cells and blood flow to the skin reduces and nerve ending are lost making skin less sensitive with age.

  • Muscular fiber decreases and slows down the person.

  • The nervous system slows down with age affecting speech, hearing, and sight. Its impact is shown on how one can read write or communicate and react.

  • Gallbladder problems and gastrointestinal problems start as the atrophic changes occur in the stomach.

  • Problems occur with pancreas and diabetes may occur.

  • The heart muscle reduces in size, plaque accumulates in the arteries and reduces their elasticity, resulting in lesser blood flow.

  • Blood Pressure problems may arise.

Many of the above-discussed problems can be avoided with regular exercise and body fitness regimen, with consumption of a well-balanced diet, maintenance of nutritional balance and hormonal balance within the body. One can surely avoid many of the internal organs damage.

Regular health checkups and medication can surely provide a timely cure and postpone or avoid serious damage. Maintenance and care are most important for the effective functioning of the human body and we can delay the effects of ageing by doing so.
