All are causes of prolapse of cervix EXCEPT: March 2013
**Core Concept**
Prolapse of the cervix is a condition where the cervix loses its normal anatomical position and protrudes into the vagina. This can be caused by a variety of factors that compromise the supporting structures of the cervix, including the uterosacral ligaments and the cardinal ligaments.
**Why the Correct Answer is Right**
The correct answer is likely to be related to the factors that contribute to the weakening of these supporting structures. For example, uterine prolapse can be caused by factors such as **chronic straining during bowel movements**, **obesity**, or **hysterectomy**. These factors can lead to the detachment or stretching of the uterosacral and cardinal ligaments, resulting in the prolapse of the cervix.
**Why Each Wrong Option is Incorrect**
**Option A:** **Chronic straining during bowel movements** is a known cause of uterine prolapse, including cervical prolapse. Therefore, this option is incorrect.
**Option B:** **Obesity** can contribute to the development of uterine prolapse by increasing the intra-abdominal pressure and stretching the uterosacral and cardinal ligaments. Thus, this option is also incorrect.
**Option C:** **Hysterectomy** can lead to the prolapse of the cervix if the supporting structures are not adequately restored during the procedure. This option is incorrect.
**Clinical Pearl / High-Yield Fact**
It's essential to note that **cervical prolapse can be asymptomatic in the early stages**, and symptoms may only become apparent when the prolapse becomes more significant, such as during physical examination or when the patient experiences discomfort or pain.
**Correct Answer:** C. Hysterectomy without restoration of the supporting structures is not a direct cause of prolapse of the cervix.
