Study Notes
Urinary Incontinence
- Urinary incontinence is involuntary urine leakage, often due to anatomical, neurological, or functional problems.
- Types include stress, urge, overflow, mixed, and functional incontinence.
Stress Incontinence
- Causes: pelvic floor muscle weakness (often from childbirth, aging, or surgery), increased intra-abdominal pressure (e.g., coughing, sneezing, heavy lifting).
Urge Incontinence
- Causes: detrusor overactivity (bladder spasms), local irritation (e.g., bladder infections), or neurological disorders (e.g., Parkinson's disease, stroke).
- Detrusor overactivity: Involuntary bladder contractions causing a sudden urge to urinate.
Overflow Incontinence
- Causes: bladder outlet obstruction (e.g., enlarged prostate, tumors), detrusor underactivity (impaired bladder emptying, due to nerve damage or medications).
Mixed Incontinence
- Combining stress and urge incontinence.
- Common in older adults.
Functional Incontinence
- Inability to reach the toilet due to physical or cognitive limitations (e.g., dementia, immobility).
Pathophysiology
- Stress: Increased intra-abdominal pressure overwhelms the urethral sphincter.
- Urge: Overactive detrusor muscle contractions.
- Overflow: Chronic bladder overfilling due to obstruction or reduced bladder emptying.
- Functional: Inability to access a toilet in time.
Risk Factors (Modifiable)
- Obesity (increases intra-abdominal pressure).
- Smoking (causes chronic coughing).
- High-impact physical activities (increase abdominal pressure).
- Diet (excessive caffeine or alcohol).
- Medications (diuretics, sedatives).
- Urinary Tract Infections (UTIs).
Risk Factors (Non-Modifiable)
- Age (older age reduces bladder function).
- Gender (women more prone to stress incontinence).
- Childbirth (weakens pelvic floor muscles).
- Neurological disorders (e.g., stroke, MS, Parkinson's).
- Spinal cord injury.
- Prostate enlargement (in men).
