Body System Changes in the Elderly
Hair, Skin, and Nails
Hair Changes:
Hair starts to gray due to decreased melanin production.
Women experience hair thinning as hormone levels change, impacting hair follicle health.
Males may experience baldness (androgenetic alopecia) and receding hairlines due to genetic factors and hormonal influences.
Hair thinning can be associated with thyroid issues (hypothyroidism or hyperthyroidism) and general aging, affecting hair growth cycles.
Graying of hair is a noticeable sign of aging, influenced by genetics and environmental factors.
Psychological Impact:
Individuals may have negative self-perception due to these changes, leading to decreased self-esteem and body image issues.
Encouragement and positive reframing are important to promote self-acceptance and mental well-being.
Skin Changes:
Wrinkles start to appear due to decreased collagen and elastin production.
Loss of elasticity results in sagging skin.
Skin becomes thinner and more prone to bruising or breaks due to reduced subcutaneous fat and weakened blood vessels.
Dryness is a common issue due to decreased oil gland activity.
Skin Care:
Moisturizing is essential to hydrate and protect the skin.
Restricting water intake can worsen dry skin; adequate hydration is necessary.
Lotions help maintain skin integrity and prevent damage.
Muscle Changes:
Muscles become weaker and lose strength (atrophy) due to decreased muscle fiber size and reduced physical activity.
Reduced ability to perform daily activities affects independence and quality of life.
Example: Farmers can't walk to the mailbox without fatigue due to muscle weakness and reduced endurance.
Nail Changes:
Fingernails and toenails thicken, especially toenails, due to slowed nail growth and increased keratin production.
Toenails can become thick, yellow, and overgrown, leading to discomfort and difficulty in trimming.
Podiatrist visits are common for nail trimming (e.g., every three months) to prevent complications and maintain foot health.
Nails become brittle and prone to splitting or cracking.
Fungal infections may occur under the nails, causing discoloration and thickening.
Nursing Assistant Role:
Nursing assistants can file fingernails to maintain hygiene and prevent injuries.
Cannot cut toenails due to risk of injury and infection, requiring specialized care.
Application to Real Life:
Relating changes to older individuals you know can improve understanding and attitude towards aging, promoting empathy and respect.
Muscle, Bone, and Joint Changes
Muscle Tone, Strength, Flexibility, and Dexterity:
Decreased muscle tone, strength, flexibility, and dexterity affect mobility and coordination.
Difficulty standing up, needing support due to weakened leg muscles and joint stiffness.
Slower walking pace due to reduced muscle power and balance.
Navigating stairs differently, often using handrails for support.
Difficulty opening jars due to decreased hand strength and dexterity.
Arthritis in hands causes pain and stiffness, affecting grip strength.
Thinner, drier skin reduces grip, making it harder to hold objects.
Decreased dexterity affects simple tasks like holding a pen; thicker pens may be needed for better grip.
Bone and Joint Changes:
Bones become more brittle due to decreased bone density (osteoporosis).
Degeneration and inflammation of joints (arthritis) cause pain, stiffness, and reduced range of motion.
Heart as a Muscle:
Heart becomes less efficient due to decreased contractility and increased stiffness.
Weaker heartbeats can cause heart failure, leading to fluid buildup and shortness of breath.
Fluid retention and decreased oxygen in the blood result from impaired heart function.
Fatigue with activities due to reduced cardiac output and oxygen delivery.
Urinary System:
More frequent urination due to decreased bladder capacity and reduced kidney function.
Fluid restriction to reduce trips to the bathroom, especially with medications like Lasix (water pill), which can worsen dehydration.
Urinary incontinence due to muscle weakness when standing or coughing, leading to involuntary urine leakage.
Appetite and Digestion:
Decreased appetite, small food intake result from reduced metabolic rate and decreased taste sensitivity.
Encourage regular meals and snacks (e.g., Ensure, Carnation Instant Breakfast) for calorie needs to maintain energy and nutrition.
Slower digestion leads to constipation due to decreased intestinal motility and reduced fiber intake.
This generation expects daily bowel movements and may request suppositories if they don't occur, reflecting established habits and expectations.
Healthcare providers typically intervene after three days without a bowel movement (e.g., MiraLAX, suppository) to prevent discomfort and complications.
Hormone Levels:
Decreased hormone levels (e.g., estrogen) impact various bodily functions.
Loss of estrogen can lead to loss of vitamin D and osteoporosis, especially in older females, increasing fracture risk.
Immune System:
Weakened immune system increases vulnerability to infections due to decreased immune cell function.
Importance of flu shots and COVID vaccines to prevent severe illness and complications.
Healthcare workers must practice good hygiene to reduce the spread of infections.
Lifestyle Changes:
Physical changes affect ability to drive, travel, and engage in activities, impacting independence and social interaction.
Impact on emotional and mental health, leading to feelings of isolation, depression, and anxiety.
Nervous System Changes
Loss of Senses:
Decreased taste and smell can reduce appetite and enjoyment of food.
Individuals lived through depression and avoid waste, leading to holding on to leftovers longer than they should, potentially causing foodborne illnesses.
Interventions:
Fresh pitchers of water to promote good taste and oral hygiene, enhancing hydration and overall health.
Decreased Sensation/Touch:
Decreased circulation can lead to neuropathy in fingers/feet, causing numbness and tingling.
Reduced ability to feel injuries or temperature changes increases risk of burns and wounds.
Keep environment free of debris to prevent injuries and maintain safety.
Vision Changes:
Presbyopia: Need to hold information farther away, need reading glasses due to decreased lens elasticity.
Difficulty with small writing affects ability to read and perform tasks requiring close vision.
Potential development of cataracts, macular degeneration or diabetic retinopathy can significantly impair vision.
Correction with lenses or surgery when possible to improve visual acuity and quality of life.
Hearing Changes:
Hearing loss due to exposure to loud machinery, especially in men, can lead to social isolation and communication difficulties.
Recognizing Hearing Loss:
Asking "What?" frequently indicates difficulty in hearing conversations.
Loud TV volume is a common sign of hearing impairment.
Smiling without answering questions may indicate misunderstanding due to hearing loss.
Interventions:
Annual screenings for vision and hearing, but hearing aids are expensive (not always covered by insurance), limiting access to assistive devices.
Memory Changes:
Poor short-term memory, good long-term memory is a common pattern in aging.
Remembering childhood memories (like riding a bicycle) reflects preserved long-term memory function.
Reality Orientation:
Daily reading of the newspaper, current date, and news helps maintain awareness of current events.
Visible clock, open windows, news programs provide sensory cues to orient individuals to time and place.
Repeat information as needed to reinforce memory and understanding.
Assessment:
Assess mentation by asking date, name, date of birth, and current president to evaluate cognitive function.
Activities to promote short-term memory can help improve cognitive skills.
Digestive System Changes
Oral Health Issues:
Poor dention, poor oral care, tooth loss cause chewing problems, affecting nutrient intake and digestion.
Poor fitting dentures can cause discomfort and difficulty in eating.
Chewing problems can lead to swallowing issues and choking hazards, posing significant health risks.
Interventions:
Speech pathologist, speech therapist, registered dietitian consult to address swallowing difficulties and nutritional needs.
Dental care to prevent malnutrition and choking, ensuring adequate oral health and safety.
Swallowing and Digestion:
Problem swallowing (dysphagia) can result from weakened muscles and neurological issues.
Slowed digestion leads to constipation and discomfort.
Food intolerances, changes in taste preferences affect dietary choices and nutrient intake.
Constipation due to poor mobility, diet and medications requires management to prevent complications.
Stool softeners may be used to ease bowel movements.
Address concerns with residents to avoid self-medication, promoting safe and appropriate healthcare practices.
Heart and Lungs Changes
Blood Vessels and Heart:
Blood vessels narrow and become fragile, leading to decreased strength and output of the heart, reducing overall cardiovascular function.
Swelling of ankles due to decreased circulation and fluid retention.
Peripheral vascular disease, poor circulation, edema, discoloration of feet/toenails indicate compromised blood flow to the extremities.
Lungs:
Decreased lung capacity, increasing risk of respiratory infections due
