A 50 year old female presents with involuntary loss of urine on coughing or sneezing since 3 years, more frequently. which of the following type of incontinence is the patient suffering from
**Core Concept**
The patient is experiencing stress urinary incontinence (SUI), a type of incontinence characterized by involuntary loss of urine due to increased abdominal pressure from activities such as coughing, sneezing, or lifting heavy objects. This condition occurs when the urethral sphincter or pelvic floor muscles are weakened, leading to inadequate support and control of the bladder.
**Why the Correct Answer is Right**
Stress urinary incontinence is caused by the sudden increase in intra-abdominal pressure, which exceeds the urethral closure pressure, resulting in urine leakage. This can be due to various factors such as weakened pelvic floor muscles, urethral sphincter damage, or hormonal changes. The patient's symptoms of involuntary loss of urine on coughing or sneezing are classic indicators of SUI.
**Why Each Wrong Option is Incorrect**
* **Option A:** Urge incontinence is characterized by a sudden, intense urge to urinate followed by involuntary loss of urine, which is not the case in this patient.
* **Option B:** Overflow incontinence occurs when the bladder is not fully emptied, leading to a constant dribbling of urine, which is not described in the patient's symptoms.
* **Option C:** Functional incontinence is caused by a physical or mental disability that prevents the patient from reaching the toilet in time, which is not applicable in this scenario.
**Clinical Pearl / High-Yield Fact**
Stress urinary incontinence is more common in women who have had multiple vaginal deliveries, hysterectomy, or pelvic surgery, highlighting the importance of maintaining pelvic floor muscle strength and bladder control throughout life.
**Correct Answer:** C.
