Effects of Aging on the Immune System

Aging affects each system of the body in different ways.  Here are some main effects of aging on the immune system:

  • Thymus gland begins to shrink, so less T-cells available to attack foreign invaders.
  • Increased risk for getting sicker than younger people from simple illnesses like the common cold.
             

WATCH FOR AND REPORT:

  • Signs of infection.
  • Signs of cold and the flu.
  • Any joint swelling, pain, or redness.
