Discovering a bulge near your belly button during pregnancy or being told you have an umbilical hernia raises an immediate and understandable concern: Is this dangerous for my baby? Can it be treated now? What are my options?
These are exactly the right questions to ask. Umbilical hernia during pregnancy is more common than most women realise, and while it does require careful monitoring and management, the majority of cases can be safely navigated with the right medical guidance.
Dr. Deepak Subramanian, a hernia specialist in Chennai, regularly consults with pregnant women and women planning pregnancy who are concerned about an umbilical hernia. This guide explains what causes this condition during pregnancy, why surgery is almost always deferred, what safe management looks like, and what your treatment options are after delivery.
What Is an Umbilical Hernia and Why Does Pregnancy Trigger It?
An umbilical hernia occurs when a small section of the abdominal lining, fatty tissue, or in some cases a loop of intestine, pushes through a weakness in the abdominal wall near the navel (belly button). The result is a soft, visible bulge that may become more prominent when you cough, strain, or stand for long periods.
The navel area is a natural anatomical weak point; it is where the umbilical cord was attached during fetal development, and while this opening closes after birth, the tissue in this region remains structurally thinner than the surrounding abdominal muscle.
Pregnancy exerts several simultaneous forces that make umbilical hernia significantly more likely to develop or worsen:
Increased intra-abdominal pressure (pressure building inside the abdomen) is the primary driver. As the uterus expands to accommodate the growing baby, it pushes against all surrounding structures, including the abdominal wall, directly stressing the navel area.
Hormonal changes, particularly the rise in relaxin and progesterone, loosen connective tissue and ligaments throughout the body to prepare for childbirth. This softening of tissue, while necessary for delivery, also reduces the structural integrity of the abdominal wall.
Diastasis recti (the separation of the two central abdominal muscle bands that run vertically down the midline) is a common pregnancy-related change that further weakens the abdomen’s midline, widening the gap through which a hernia can develop.
Multiple pregnancies, carrying twins or multiples, and a history of previous abdominal surgery all elevate the risk further.

Is an Umbilical Hernia During Pregnancy Dangerous?
For most pregnant women, an umbilical hernia presents as a manageable condition rather than an immediate threat. However, the level of risk depends on the size of the hernia defect, the contents of the hernia sac (what has pushed through), and whether any complications develop.
The most serious, though relatively uncommon, complication is incarceration (when the herniated tissue becomes trapped and cannot be pushed back into the abdomen) or strangulation (when blood supply to the trapped tissue is cut off, creating a surgical emergency). According to the Royal College of Surgeons of England, strangulation requires urgent surgical intervention regardless of pregnancy status.
Warning signs that require immediate medical attention during pregnancy include:
- A hernia bulge that suddenly becomes hard, tender, or cannot be pushed back in
- Severe or worsening pain at the navel site
- Nausea and vomiting alongside localised hernia pain
- Skin discolouration (redness or darkening) around the bulge
- Fever accompanying hernia-related symptoms
Outside of these complications, most umbilical hernias during pregnancy are reducible (can be gently pushed back) and are monitored rather than surgically treated until after delivery.
Why Is Surgery Almost Always Deferred During Pregnancy?
This is one of the most common questions patients ask, and the reasoning is sound from both a maternal and fetal safety standpoint.
General anesthesia carries inherent risks during pregnancy. Certain anesthetic agents can affect fetal heart rate, oxygen delivery to the placenta, and uterine muscle tone. While emergency surgery under anesthesia is performed when necessary, elective or semi-elective procedures are avoided whenever possible, particularly in the first and third trimesters.
Surgical access becomes increasingly difficult as the uterus enlarges. Operating near the umbilicus (navel) during the second or third trimester is technically more complex, with a higher risk of accidental injury to surrounding structures.
The uterus itself may partially address the hernia. As the uterus expands, it can naturally support the hernia from below, preventing worsening during the pregnancy itself even though the hernia will typically become more apparent again after delivery.
Postpartum healing offers a better surgical window. After delivery, the abdominal anatomy returns closer to its pre-pregnancy state, making the repair technically more straightforward and the outcomes more predictable.
The American College of Obstetricians and Gynaecologists (ACOG) recommends that non-urgent abdominal surgery during pregnancy, when unavoidable, is safest in the second trimester, but emphasises that elective hernia repair should be postponed until after delivery whenever clinically feasible.
Managing Umbilical Hernia Safely During Pregnancy
While surgery waits, proactive management keeps you and your baby safe and minimises discomfort throughout the pregnancy.
Hernia support belts and maternity bands provide external compression that gently supports the abdominal wall and reduces the outward pressure on the hernia site. A hernia specialist or physiotherapist should guide you on the appropriate type and fit; incorrect compression can cause discomfort or be counterproductive.

Avoid activities that significantly raise intra-abdominal pressure. Heavy lifting, intense core exercises, and straining during bowel movements all increase the pressure on the hernia. Managing constipation proactively through adequate hydration, dietary fibre, and pregnancy-safe stool softeners if needed is a practical but often overlooked priority.
Maintain appropriate weight gain. While healthy weight gain during pregnancy is both normal and necessary, excessive weight gain accelerates abdominal pressure on the hernia site. Your obstetrician can guide you on appropriate gain targets based on your pre-pregnancy BMI (Body Mass Index, a measurement of weight relative to height).
Regular monitoring by your hernia specialist alongside your obstetric team ensures that any change in hernia size, reducibility, or symptoms is caught early. A hernia that was uncomplicated at 16 weeks may behave differently at 32 weeks, when abdominal pressure peaks.
Positioning during rest. Sleeping on your side with a supportive pregnancy pillow reduces direct pressure on the abdominal midline compared to lying flat on your back, which is also not recommended in later pregnancy for circulatory reasons.
What About Women Planning Pregnancy Who Already Have a Hernia?
If you are planning a pregnancy and have a known umbilical hernia, even a small, asymptomatic one, it is worth consulting a hernia specialist before conception. This gives you two important advantages:
First, if the hernia is small and repair is straightforward, elective repair before pregnancy eliminates the risk of it enlarging or complicating during gestation. Recovery from umbilical hernia repair is typically measured in weeks, not months, meaning surgery well before a planned conception is entirely feasible.
Second, if the hernia is very small and you and your surgeon agree that watchful waiting is appropriate, you enter the pregnancy with a documented baseline, so any change during pregnancy is immediately measurable and contextualised.
Waiting until a hernia becomes symptomatic during pregnancy, when surgical options are limited, is a position worth avoiding if planning ahead is possible.

Umbilical Hernia Repair After Delivery: Your Postpartum Options
Most women who have managed an umbilical hernia through pregnancy will be candidates for surgical repair after delivery. The recommended waiting period is typically 3 to 6 months postpartum (after childbirth), long enough for the abdominal wall to regain meaningful strength and for breastfeeding to be well established before any anesthesia is considered.
Laparoscopic mesh repair (keyhole surgery using a camera and small incisions, with a synthetic mesh to reinforce the abdominal wall) is the preferred approach for most umbilical hernias. It offers faster recovery, less postoperative pain, and a significantly lower recurrence rate compared with open non-mesh repair.
Open repair may be recommended for larger defects, cases in which previous abdominal surgeries have created scar tissue (adhesions), or cases in which the hernia is complex. Your surgeon will determine the most appropriate technique based on defect size, tissue quality, and your overall health at the time of repair.
Women who developed significant diastasis recti during pregnancy, and whose hernia is partly related to midline muscle separation, may benefit from a combined repair addressing both conditions simultaneously. This should be discussed with a hernia specialist who has experience managing post-pregnancy abdominal wall reconstruction.

Recurrence Risk After Postpartum Repair: What to Consider
Women who plan further pregnancies after umbilical hernia repair should discuss timing carefully with their surgeon. A subsequent pregnancy places the same mechanical stresses on the repaired abdominal wall, potentially straining the mesh or repair site. As a general principle, completing your family before undergoing elective hernia repair produces the most durable long-term outcome.
If a further pregnancy follows a repair, this does not mean complications are inevitable, but it does mean closer monitoring during subsequent pregnancies is warranted.
Specialist Care Makes a Difference
Navigating an umbilical hernia during pregnancy requires coordination between your obstetric team and a hernia specialist not a generic surgical consult. Dr. Deepak Subramanian at Chennai Hernia Care provides specialist evaluation that accounts for both your pregnancy and your hernia, giving you a clear, personalised management plan from diagnosis through to postpartum repair.

Frequently Asked Questions (FAQs)
In the vast majority of cases, an uncomplicated umbilical hernia does not directly harm the developing baby. The risk is primarily to the mother, specifically if the hernia becomes incarcerated or strangulated, which requires urgent surgical management. Regular monitoring by your obstetric and surgical team keeps this risk well-managed.
Elective hernia repair is almost always postponed until after delivery due to the risks of anaesthesia during pregnancy and the technical challenges of operating near an expanding uterus. Emergency surgery is performed when complications like strangulation occur, regardless of gestational age.
Small umbilical hernias occasionally reduce in size postpartum as abdominal pressure decreases. However, they do not resolve completely without surgical repair. Most hernias that were present during pregnancy will require repair after delivery to prevent worsening over time.
Gentle, low-impact exercise approved by your obstetrician is generally safe. However, exercises that significantly increase intra-abdominal pressure, such as heavy lifting, sit-ups, or intense core work, should be avoided. A physiotherapist experienced in antenatal (pregnancy) care can guide appropriate modifications.
Most surgeons recommend waiting 3 to 6 months after delivery to allow adequate abdominal wall recovery. If you are breastfeeding, your surgeon and anesthetist will take this into account when determining the timing and choice of anesthetic agents.
An umbilical hernia occurs directly through the navel opening, while a paraumbilical hernia (para meaning “beside”) develops just adjacent to it. Both are managed similarly during pregnancy, though their precise anatomy influences the surgical repair technique used postpartum.
