Geriatric Care Notes

Nutrition in Aging

  • As we age, we typically need fewer calories.
  • Bone density decreases with age, increasing the risk of fractures.
  • A minimum of 1000 mg of calcium is needed daily (more for those with osteoporosis).
  • After age 30, height can decrease by 1 cm per decade.
  • 60% of the diet should be carbohydrates, 12-13% protein, and 30% fat.
  • Older adults often consume insufficient protein due to its cost, opting for cheaper, less nutritious foods.
  • Fiber is crucial for gut health.
  • Recommended daily fiber intake: 25-50%.
  • Calcium absorption requires Vitamin D.
  • It's better to take calcium in divided doses (e.g., 500 mg twice a day) with 1-2 hours between doses.
  • Recommended daily servings:
    • Grains: 6 servings (restaurant portions can equal 5 servings).
    • Vegetables: 3-5 servings.
    • Fruits: 4 servings.
    • Dairy: 2-3 servings minimum.
    • Poultry/Meat: 8-9 servings.
    • Fish/Seafood: 2-3 servings, but limit due to mercury content.
    • Nuts, seeds, and beans can be used as protein sources, aiming for 5 servings weekly.
    • Fats and oils: approximately 3 servings.
  • These recommendations are based on a 2000-calorie diet.
  • Educate older adults on calcium-rich food sources and consider a nutritionist consult especially if they need specific guidance.

Osteoporosis

  • Bone mass decreases with age due to increased absorption and decreased bone formation, leading to a higher risk of fractures.
  • Type 1 Osteoporosis: Most common in postmenopausal women due to estrogen loss. Estrogen is crucial for bone strength.
  • Type 2 Osteoporosis: Occurs in both men and women due to aging.
  • Risk Factors:
    • Family history.
    • Inactivity/immobility.
    • Low calcium intake (below 80 mg/day).
    • Excessive alcohol and caffeine consumption (compete with calcium absorption).
    • Celiac disease and other bowel issues (affect nutrient absorption).
    • Low birth weight or body weight.
    • Hyperparathyroidism (impacts calcium absorption).
    • Early menopause (due to estrogen loss).
  • Prevention:
    • Avoid tobacco.
    • Regular exercise (even walking).
    • Limit caffeine and alcohol.
    • Hormone replacement therapy (HRT) for menopausal women to help with bone health.
    • Ensure adequate Vitamin D and calcium intake.
    • Maintain a safe environment to prevent falls.

Importance of Exercise

  • Lack of exercise leads to physical decline.
  • High-intensity progressive resistance training can improve muscle strength and size in older adults.
  • Physical therapy can help individuals regain strength and mobility after illness or surgery.
  • Exercise helps well-being and reduces the risk of depression.
  • Consult a physician before starting a new exercise program.

Physiological Changes Affecting Nutrition

  • Decreased average blood circulation.
  • Increased threshold for thirst sensation (for sugar and salt).
  • Decreased number of taste buds.
  • Decreased peristalsis, gastric secretions, and saliva production.
  • Decreased stomach capacity and stomach emptying.
  • Diminished sense of smell or taste.
  • Increased indigestion.
  • Decreased hunger and appetite.
  • Increased need for protein intake with illness or surgery as they're more prone to joints replacement. Increase protein intake before surgery to improve recovery.

Hygiene in Aging

  • Good hygiene and grooming are essential for self-esteem.
  • Adapt hygiene practices to changes in the aging body.
  • Factors Affecting Hygiene:
    • Increased skin dryness.
    • Decreased skin elasticity.
    • Increased sensitivity to temperature.
    • Decreased sense of smell.
    • Decreased physical movement.
    • Nail changes.
    • Tooth wear and tear.
    • Decreased saliva production.

Immunity in Aging

  • The thymus gland shrinks after adolescence, impacting T-cell maturation.
  • T-cell numbers don't decrease with age, but their function declines.
  • This reduces the immune system's ability to fight off infections, increasing the risk of infection and reducing the effectiveness of immunizations.
  • It can also lead to autoimmune issues.

Infections in the Elderly

  • Infections in older adults can be difficult to diagnose because they may not exhibit typical symptoms like fever.
  • The body's response to infection is often muted.
  • Septicemia (systemic infection) is a significant risk.
  • Subtle signs to watch for:
    • Subnormal temperatures.
    • Increased pulse rate.
    • Unexplained dehydration.
    • Loss of appetite.
    • Confusion or cognitive changes.
  • Respiratory Infections:
    • May not cough as effectively.
    • Increased respiratory rate.
    • Loss of appetite.
  • Urinary Infections (UTIs):
    • Pain is an important indicator.
    • Incontinence or worsening of existing incontinence.
    • Changes in urine color and smell.
  • Skin Infections:
    • Redness, pain, and tenderness in affected areas.

Chronic Illnesses in Aging

  • Aging is a normal process; illness is a pathological one.
  • Chronic illnesses are more prevalent in older adults, affecting all aspects of their lives.
  • 95% of healthcare dollars for older Americans are spent treating chronic illnesses.
  • Financial challenges:
    • Meeting healthcare expenses.
    • Rising medication costs.
  • Polypharmacy (multiple medications) is common, potentially leading to drug interactions and side effects that require additional medications.

Sleep Disturbances in Aging

  • Sleep patterns change with age, but the need for sleep does not decrease.
  • Central nervous system controls sleep-wake cycle.
  • Two main types of sleep: REM and non-REM (with 3 stages of non-REM).
  • Sleep disturbances:
    • Tend to sleep less than 8 hours per night, with increased awakenings and insomnia. Breaking up sleep with small bladders or aches and pains.
    • Decreased stage 3 and REM sleep.
    • Early awakenings and daytime fatigue.
  • Strategies for better sleep:
    • Maintain a consistent routine.
    • Create a comfortable sleep environment (temperature, noise, lighting).
    • Address pain and discomfort.
    • Avoid large meals, caffeine, and alcohol before bed.
    • Daytime naps are okay.
    • Exercise early in the day
  • Avoid sleep medications (tranquilizers, sedatives) as a first resort.

Adapting to Aging

  • Address adjustments associated with aging.
  • Factors affecting adjustment to retirement:
    • Limited income.
    • Preference for younger workers.
    • Health issues.
  • Geriatric Syndromes: Common health conditions in older adults, even without chronic illnesses
  • Adaptive Measures:
    • Home modifications (grab bars, clear pathways).
    • Lifestyle adjustments.
Nighttime Falls
  • Add night lights or keep a bathroom or hall light on all night.
  • Put on glasses even on a quick trip to the bathroom.
  • Sit a moment before rising and get up slowly to improve balance.
  • Use a walker, cane, or other assistive device even at home for improved safety.
Reduce Muscle Strength Effects
  • Remove clutter and provide a clear path to a favorite chair, a chair that is high enough to get up from easily.
  • Electrical cords are a well known hazard that can easily be secured with tape near the edge of a rug.
  • Use higher seating.
  • Clear pathways.
  • Secure electrical cords.
Medications Considerations
  • A medication organizer can help avoid double dosage.
  • This is important since older adults process medications through their system more slowly than younger people.
  • Because many older adults take more than one prescription plus over the counter drugs, the risk of drug interaction is increased.
  • A medication reviewed by a pharmacist or physician will reduce this risk.
Unsafe Climbing Considerations
  • Keep dishes, canned goods, and cooking utensils at eye level reduce the need for unsafe climbing.
  • Wear comfortable but secure footwear to improve balance.
  • Reduce the need to climb, and use safe footwear.
Bath Time Considerations
  • Use a tub mat and dry off inside the tub or shower. A bath stool can make this easier
  • Use a detachable grab bar for security and a large bath mat with non skid backing.
  • Reduce slippery surfaces and install and use grab bars.
Step Considerations
  • Increase the contrast between different levels.
  • Keep walkways clear of debris to reduce the risk of falling.
Fall Prevention
  • Pay attention to and discuss any side effects of medications such as dizziness or confusion with your doctor.
  • Have vision checked and wear corrective lenses if prescribed.
  • Improve balance through daily walks, stretching exercises, and exercises while sitting.
  • Wear supportive low heeled shoes and use walkers and canes as prescribed by your doctor to reduce risk.
  • Reduce clutter and debris, improve lighting both inside and outside, and mark level changes with contrasting tape.
