Bones, Joints and Muscles - With age, bones tend to shrink in size and density and muscles generally lose strength, endurance and flexibility.
Digestive Health - Aging causes modest decline in the function of the esophagus, stomach, colon, pancreas and liver. Older adults are more likely to have digestive tract disorders.
Bladder and Urinary Health - The bladder may become less elastic as you age, resulting in the need to urinate more often.
Memory - Your brain undergoes changes as you age that may have minor effects on your memory or thinking skills.
Eyes and Ears - With age, you might have difficulty focusing on objects that are close up. Your hearing also might diminish.
Teeth - Older adults are more at risk for dry mouth. This can occur because of age, medicine use, or certain health conditions.
Skin - With age, your skin thins and becomes less elastic and more fragile, and fatty tissue just below the skin decreases.
Weight - How your body burns calories (metabolism) slows down as you age.
