Physical Changes

physical changes

determined by genetics, lifestyle, and disease

body shape

naturally changes due to lose lean tissue and some cells in muscles, liver, kidney, other organs are lost

tissue loss

reduces the amount of water in one's body = bones lose minerals = become less dense

osteopenia

bones becoming less dense

EARLY STAGE

osteoporosis

bones becoming less dense

LATER STAGE

fat tissue

tissue that builds up toward the center of the body, including around the internal organs

skin

thinner, less elastic, veins and bones seen, scratches/cuts/bumps = longer to heal

skin

exposure to sun lead to wrinkles, dryness, age spots, and cancer

skin

sags and wrinkles due to GRAVITY

smoking -> wrinkling

age spots

flat, brown spots cuased by years in the sun

HARMLESS

liver spots

age spots previously called ???

skin tags

small, usually flesh-colored growths of skin that have a raised surface

HARMLESS

hair loss

due to hair growth slowing down as one ages = HAIR FOLLICLES stop producing new hair

loss of pigment

in hair, begins in middle adulthood and continues into late adulthood

facial hair

this hair may grow coarser

nails

becomes hard, thick, and may develop lengthwise ridges

height loss

become shorter due to aging changes in the bones, muscles, and joints

weight loss

men gain until 55, then lose it

women gain until 65, then lose it

weight loss

occurs partly because fat replaces lean muscle tissues

muscle heavier > fat

sarcopenia

loss of muscle tissue as a natural part of aging

MOST NOTICEABLE IN MEN

sarcopenia

symptoms: loss of stamina, weakness = decrease phys activity = further shrinking muscles

happens faster around 75

sarcopenia

reduction in nerve cells responsible for sending signals to the muscles from the brain to begin moving

sarcopenia

decrease in the ability to turn protein into energy, and not receiving enough calories or protein to sustain adequate muscle mass

sarcopenia

factor in frailty
