2. Urinary and elimination

2.1. Normal changes of aging

2.1.1. Urinary Ineffective filtration of drugs and wastes from blood due to 50% loss of nephrons Decreased resorption of glucose Increased urinary frequency Weaker bladder muscles Decreased bladder capacity Prostate enlargement Incomplete emptying of bladder/ urinary retention

2.1.2. Elimination/digestion Presbyesophagus Decrease in bile synthesis Reduced hepatic blood flow Incomplete emptying of the bowel Reduction of pepsin Decreased elasticity of the stomach Decrease in saliva production Decreased absorption Decreased appetite

2.2. Pathological changes of aging

2.2.1. Digestion/elimination Periodontal disease Infection of the gums, can lead to systemic infection in older adults

2.2.2. Urinary Bladder cancer Causes: chronic bladder irritation

3. Endocrine

3.1. Normal changes of aging

3.1.1. Atrophied thyroid gland Lower basal metabolic rate

3.1.2. Reduced adrenal gland function Reduced estrogen, progesterone, androgen, glucocorticoids

3.1.3. Reduced insulin release

3.1.4. Reduced tissue sensitivity to insulin Reduced ability to metabolize glucose

3.1.5. Pituitary gland atrophy

3.2. Pathological changes of aging

3.2.1. Diabetes mellitus The inability of the cells to uptake glucose out of the blood stream related too poor insulin function Hypoglycemia Hyperglycemia Can result in high bp, delayed wound healing, decreased blood flow/ oxygenation to tissues, neuropathy, loss of limbs

3.2.2. Hypothyroidism Decreased T3 and T4 Fatigue, weakness, lethargy, depression, disinterest in activities, anorexia, weight gain, impaired hearing, constipation, cold intolerance, myalgia, dry skin, coarse hair, periorbital and peripheral edema

4. Reproductive

4.1. Male

4.1.1. Normal changes of aging Andropause Decline in testosterone Decreased capacity to retain fluids Ejaculation fluid contains less live sperm Enlargement of prostate gland Atrophy of testes and reduction of testicular mass More time required to get an erection

4.2. Female

4.2.1. Normal changes of aging Menopause Estrogen levels fall, menses cease Vulva atrophies Flattening of labia Loss of subcutaneous fat and hair Cervix, uterus, and Fallopian tubes atrophy Vaginal epithelium thins Less lubrication, more alkaline ph

4.3. Pathological changes of aging

4.3.1. Prostate cancer Back pain, anemia weakness, weight loss Confirmed with biopsy

4.3.2. Ovarian cancer S&S: GI discomfort, bleeding, ascites, presence of a mass Cancer treatment

5. Immune system

5.1. Pathological changes of aging

5.1.1. Urinary tract infection Bacteria in the urinary tract Caused by urinary retention, incomplete voiding, wiping back to front, low fluid intake, excessive fluid loss, hormone changes.

5.2. Normal changes of aging

5.2.1. Increased susceptibility to infection
