Aging Symptoms

The body inevitably experiences deterioration over time. This affects all body processes in general. However, some people experience greater symptoms of a body process's deterioration than others, in single or multiple body processes. As always, both genetics and environmental conditions play a role. Let's take a look at common consequences of aging on different body processes and their potential causes.

Arteries and heart - greater strain on heart, higher blood pressure

• heart becomes less efficient
• blood vessels become less elastic
• fatty deposits accumulate on the interiors of blood vessels

Body fat - more body fat accumulation

• metabolic rate slows
• increasing inactive lifestyle
• gradual decline in muscle mass

Bones - easier to break or fracture bones

• body produces less and less bone
• tendency to lose more bone than we can replace
• decrease in bone density (osteopenia, osteoporosis)

Bladder - urinary incontinence

• hormonal changes
• enlarged prostate gland
• deterioration in bladder capacity (obesity and constipation)

Brain - memory difficulties, difficulties in coordinating our muscles for sports or other physical activities (e.g. balance), and reflexes slow down

• brain cells (neurons) die

Digestive System - frequent constipation, body becomes less effective at breaking down, and therefore, absorbing nutrients from food

• decreased production of enzymes
• surface area of the intestines decreases which controls absoprtion

Hearing - hearing loss

• nerves for hearing may become damaged
• tiny hairs that line the interior of our ears may become damaged

Kidneys - less efficiency removing toxins from the blood

Lungs - lung capacity decreases

• less physically active
• smokers may have significant difficulties and greater strain on the lungs

Muscles - muscle mass may decline

• decreasing hormones (e.g. testosterone)
• decreased physical activity

Sight - vision decreases, greater difficulty dealing with glare, low-light situations (e.g. driving at night), and increased difficulty in seeing moving objects

• thinning of the retina
• lower production of tears from the tear glands (that lubricate the eye)
• stiffening of the irises

Skin, nails, and hair - wrinkles or more frequent bruising

• skin becomes less elastic
• skin becomes more fragile
• skin sweats less
• hair becomes grey and less full
• nails grow less

Teeth - weaken and darken

• inattentive dental care
• decreased production of saliva
