Uterine prolapse is a medical condition in which the tissues that support the uterus—namely the pelvic muscles and ligaments—become weak, causing the uterus to descend from its normal position in the pelvis. The uterus may slip downward inside the vagina and, in severe cases, protrude partially or completely outside the vaginal opening.
Uterine prolapse is a distressing condition for many women, particularly those who have had vaginal deliveries, suffer from weakened pelvic floor muscles, or experience stretching and weakening of the pelvic ligaments to the point where they can no longer adequately support the uterus. Mild uterine prolapse usually does not require treatment, but cases that cause discomfort or interfere with daily life may need medical intervention.
According to Dr. Jasser Abdel Ghaffar, Professor of Obstetrics and Gynecology, uterine prolapse does not directly affect fertility or the ability to conceive. However, it may complicate pregnancy and childbirth due to increased pressure on the cervix and potential effects on fetal nourishment, which makes close medical supervision and special delivery recommendations essential.
Causes of Uterine Prolapse
Weak Muscles and Supporting Tissues
Repeated pregnancies—especially closely spaced ones—can weaken the pelvic floor muscles and tissues that support the uterus, increasing the risk of prolapse, particularly after difficult vaginal deliveries. In some cases, cervical ligaments may be naturally weak, leading to prolapse even before marriage or childbirth.
Advancing maternal age also plays a role, as estrogen levels decline with age, reducing the strength and vitality of pelvic muscles and ligaments. Additionally, pelvic floor and perineal muscle tears during childbirth—especially if not properly repaired—can contribute to uterine prolapse.
Difficult or Improper Labor
Pushing before full cervical dilation, or attempting assisted delivery (using forceps or vacuum extraction) before the cervix is fully dilated, can weaken cervical ligaments and pelvic support structures.
Increased Weight and Obesity
A large fetal size places added pressure on pelvic muscles. During delivery, tearing of surrounding membranes may occur, reducing their ability to support the uterus. Obesity, chronic constipation, chronic coughing, genetic predisposition, and repeated vaginal births are also contributing factors.
Hormonal Changes
Pregnancy hormones cause increased flexibility and softness in the pelvic structures, which can lead to tissue stretching. Pregnancy may occur alongside partial uterine prolapse, but such cases require careful and specialized medical follow-up.
Chronic Pressure on the Abdomen
Factors that increase intra-abdominal pressure and push the uterus downward include:
Chronic coughing
Chronic constipation
Lifting heavy objects
Abdominal tumors
Symptoms of Uterine Prolapse
Common symptoms include:
A feeling of heaviness or pressure in the pelvis
Lower back pain
Protrusion of tissue from the vaginal area or the sensation of sitting on a small ball
Difficulty urinating or having bowel movements
Vaginal bleeding or increased vaginal discharge
Constipation and urinary problems such as incontinence or incomplete bladder emptying
Recurrent bladder infections
Weakness of vaginal tissues
Discomfort while walking
A sensation of tissue rubbing against clothing
Stages of Uterine Prolapse
Uterine prolapse is classified into stages based on severity:
Partial prolapse: The uterus descends inside the vagina without protruding.
Complete prolapse: Part of the uterus protrudes outside the vaginal opening.
Severity Grades:
Grade 1: The cervix descends into the vaginal canal.
Grade 2: The cervix reaches the vaginal opening.
Grade 3: The cervix protrudes outside the vagina.
Grade 4: The entire uterus is outside the vagina due to severe weakness of all supporting muscles.
Managing Uterine Prolapse During Pregnancy
Regular medical follow-up is essential, especially during the first trimester.
As pregnancy progresses, the pelvis may provide additional support to the uterus in some cases.
Kegel exercises help strengthen pelvic floor muscles.
Avoid activities that increase pressure, such as heavy lifting, straining during bowel movements, chronic coughing, and constipation.
Treatment Options
Non-surgical: Pelvic floor exercises, vaginal pessaries, and lifestyle modifications.
Surgical: Tightening supportive tissues or hysterectomy in severe cases (usually postponed until after delivery unless absolutely necessary).
Prevention Tips to Reduce the Risk of Uterine Prolapse
While some risk factors—such as multiple vaginal deliveries or childbirth at an older age—cannot be avoided, the following measures may help reduce the risk:
Maintain a healthy weight and exercise regularly.
Perform Kegel exercises consistently.
Avoid exposure to smoking environments to reduce chronic coughing.
Use proper techniques when lifting heavy objects.
Prevent constipation and avoid straining during bowel movements.
Complications of Uterine Prolapse During Pregnancy
Uterine prolapse during pregnancy can be dangerous for both the mother and the baby. Possible complications include cervical infections, vaginal bleeding, preterm labor, and even miscarriage. In some cases, treatment may require surgical intervention, which can pose additional risks to the pregnant woman.
