Comprehensive Clinical Notes on Geriatric Physiology and Health Maintenance

Gastrointestinal Motility: As individuals age, there is a noted decrease in the motility of the intestines. While this can lead to constipation, it is the underlying decrease in intestinal movement that is the primary physiological change.
Hemorrhoids: The speaker clarifies that hemorrhoids are not a direct consequence of aging themselves. Rather, they are associated with chronic straining during bowel movements. While elderly individuals may experience constipation, hemorrhoids are not a universal condition associated with getting older.
Salivary Production: There is a decreased production of saliva in older adults, which contributes to various oral health issues.
Dental Health Complications:
- Increased prevalence of dental problems.
- Gum disease (gingivitis).
- Missing teeth and the potential need for dentures.

Incontinence and Leakage: Leakage is common among the elderly, which explains the commercial prevalence of pads and incontinent products. Practical management includes frequent bathroom trips throughout the day.
Prostate Hypertrophy:
- Men frequently experience hypertrophy (enlargement) of the prostate.
- The prostate is located right behind the ureter, directly influencing urination patterns.
- Symptoms include trouble starting the stream and urgency (the feeling that one almost cannot make it to the bathroom).
- Onset of prostate issues can begin as early as an individual's $40s$ , well before the age of $65$ .
Medical Treatment for Prostate Issues:
- Benign Prostatic Hyperplasia (BPH): Defined as an enlargement that is not cancerous. It is often treated with medication intended to shrink the gland.
- Malignancy: If the enlargement is found to be cancer, surgical removal is usually required.

Endocrine Changes: There is a decrease in the sensitivity of tissue cells to insulin as one ages.
Immune System Decline:
- Immunization Response: There is a decreased response to immunizations.
- T-cell Function: A noted decrease in T-cell function occurs.
- B-cells: There is a decreased production of antibodies by the B-cells.
- Autoimmune Response: There is an increase in antibodies that act against one's own body, leading to a higher autoimmune response.
Thermoregulation: A decrease in the core body temperature is observed in older populations.

Cognitive Maintenance: Contrary to popular belief, many older people maintain their cognitive function. While there may be a decrease in the speed of cognitive function, the actual ability to learn and process remains intact. Older adults can still learn new technologies, such as computers, though the process may take longer.
Impact of Overall Health: Cognitive and functional ability is heavily dependent on overall health and stress levels.
Delirium vs. Dementia:
- Dementia: Characterized as chronic and progressive. It often has no known cause. Examples include Alzheimer's disease and vascular dementia. It is permanent and worsens over time.
- Delirium: Characterized as acute and temporary. It is a sudden onset of strange behavior or confusion. It is often caused by an underlying medical issue, such as a severe Urinary Tract Infection (UTI). Once the cause is treated (e.g., treating the UTI), the patient typically returns to their baseline mental state.

Causes of Depression in the Elderly: Depression can be chronic, acute, or gradual. Older adults face significant stressors, including the loss of life partners, the loss of children, and social isolation due to living alone or chronic disease.
Suicide Warning Signs: Giving away belongings or cleaning out one's house can be signs that an elderly person is tired, depressed, or becoming suicidal.
Barriers to Mental Healthcare: The speaker notes that certain communities, particularly people of color, may face cultural barriers or stigmas regarding seeking help from psychologists or psychiatrists.

Physical Decline: Unless an individual identifies as a bodybuilder, aging typically results in a decrease in physical strength and endurance.
Mobility Impairments: Factors affecting mobility in the elderly include:
- Coronary Artery Disease (CAD) and Hypertension.
- Arthritis.
- Osteoporosis: Defined as a decrease in calcium within the bones.
- Gout.

Vaccinations (CDC Recommended):
- Pneumococcal (Pneumonia).
- Seasonal influenza (Flu).
- COVID- $19$ and associated boosters.
- Shingles.
- Tdap (Tetanus, Pertussis, and Diphtheria).
- Hepatitis A and B.
- Meningococcal.
Health Screenings:
- Gastrointestinal: Fecal occult blood test.
- Men's Health: Rectal exams and PSA (Prostate Specific Antigen) tests.
- Musculoskeletal: Scans for osteoporosis.
- Vision: Eye examinations for glaucoma or cataracts.
- Mental Health: Annual screenings for depression, including questions about self-worth and mood.
- Metabolic: Cholesterol and diabetes screenings.
- Hearing: After age $65$ , a hearing screening should be offered every $1$ to $3$ years.

Dysphagia: Swallowing problems can significantly affect nutrition.
Fluid Intake: Some elderly individuals deliberately drink less fluid to avoid the need to urinate frequently (due to incontinence concerns), which can lead to dehydration and further constipation.
Dietary Adherence: Prescribed diets (low sodium or low fat) often fail because patients find the food unpalatable without salt or fat, causing them to lose interest in eating entirely.

Question (Audience/Student): Do they have an increase of hemorrhoids too?
Response (Speaker): Not from getting old directly. If a person has hemorrhoids because they are straining all the time, that person has it because they're straining all the time, but not every elderly person strains. You don't think of hemorrhoids as an "old people thing."
Question (Audience/Student): What about diseases/disorders?
Response (Speaker): Mentioned dementia, chronic pain, and dental issues like gum disease, missing teeth, and gingivitis. The speaker also touched on the legal/ergonomic protections for modern nurses to prevent back and knee pain that older generations of nurses often suffer from.
