A periumbilical hernia is a bulge that forms when tissue or part of the intestine pushes through a weak spot in the abdominal wall near the belly button. The term “periumbilical” means “around the navel,” and in clinical practice it’s used almost interchangeably with umbilical hernia, since the weakness occurs at or just beside the umbilical ring where your umbilical cord once attached. About 90% of these hernias in adults are acquired over time rather than present from birth, and they’re three times more common in women than in men.
What It Looks and Feels Like
The hallmark sign is a soft swelling or bulge near your navel. It may be most noticeable when you cough, strain, or bear down, and it often flattens or disappears when you lie on your back. In many cases the hernia is painless, especially early on. As it grows, you may notice a dull ache or discomfort in the area, particularly after standing for long periods, lifting something heavy, or exercising.
In infants, a periumbilical hernia can make the belly button stick out noticeably during crying. Most childhood cases are harmless and close on their own. In adults, the hernia tends to persist or gradually enlarge, and abdominal discomfort becomes more common over time.
Why It Develops
The umbilical ring is a natural weak point in your abdominal wall. Anything that stretches the surrounding muscles or repeatedly raises pressure inside the abdomen can widen that gap enough for tissue to push through. The most common risk factors are obesity, multiple pregnancies, fluid buildup in the abdomen (ascites), chronic constipation, and repetitive heavy lifting. Connective tissue disorders and metabolic syndrome also increase risk.
Excess body fat and stretched abdominal muscles can separate muscle fibers and weaken the connective tissue layer that holds everything together. That’s a key reason prevalence peaks between ages 31 and 40 in women (often linked to pregnancy and childbirth) and between 61 and 70 in men, when accumulated wear on the abdominal wall catches up.
How It’s Diagnosed
Most periumbilical hernias are diagnosed with a simple physical exam. Your doctor will ask you to stand, cough, or bear down while they feel the area around your navel for a bulge. In straightforward cases, no imaging is needed. When the hernia is small, hard to feel (especially in people with a higher body weight), or when the doctor needs to rule out other causes of a lump, an ultrasound or CT scan can confirm the diagnosis and measure the size of the defect in the abdominal wall.
Watchful Waiting vs. Surgery
Not every periumbilical hernia needs immediate surgery. In children, these hernias frequently close on their own. Complications from an untreated pediatric umbilical hernia are rare: only about 1 in 1,500 leads to tissue getting trapped inside. Current guidance recommends watchful waiting until age 4 and referring to a surgeon only if the hernia hasn’t closed by then.
In adults, the calculus is different. The abdominal wall won’t repair itself, so the hernia typically stays the same size or grows. If yours is small, painless, and easily pushed back in, your doctor may monitor it with periodic check-ups. Surgery is generally recommended when the hernia causes persistent pain, keeps getting larger, or shows signs of complications.
Complications to Watch For
The two serious complications are incarceration and strangulation. An incarcerated hernia means the tissue or intestine that has pushed through becomes stuck and can’t be pushed back in. Blood still flows to the trapped tissue at this stage, but the situation can worsen.
Strangulation happens when pressure from the surrounding muscle eventually cuts off blood supply to the trapped tissue. This is a medical emergency. Intestinal tissue can begin to die in as little as four hours once blood flow is reduced, potentially leading to gangrene or widespread infection. Warning signs include sudden severe pain at the hernia site, nausea and vomiting, and skin over the bulge turning red or dark. If you notice these symptoms, call emergency services immediately.
Surgical Repair Options
Two main approaches exist for fixing a periumbilical hernia: open repair and laparoscopic (keyhole) repair. In open surgery, the surgeon makes a single incision near the navel, pushes the protruding tissue back into place, and closes the gap. In laparoscopic repair, several small incisions allow a camera and instruments to do the same work with less disruption to surrounding tissue.
The bigger decision is whether the gap gets closed with stitches alone or reinforced with surgical mesh. For small defects under about 1.5 to 2 centimeters, stitches alone can work well. But as the defect gets larger, suture-only repair carries a much higher chance of the hernia coming back. One large study of over 1,300 patients found a 21% recurrence rate with suture repair compared to 10% with mesh at roughly four and a half years of follow-up. A randomized trial of 300 patients showed an even starker contrast: 11.4% recurrence with stitches versus 3.6% with mesh. For defects larger than 1.5 centimeters closed with stitches alone, the recurrence rate climbed to 7.3%, and the risk of coming back was roughly seven times higher than when mesh was used.
Overall, recurrence rates for periumbilical hernia repair range from about 3% to 27%, depending on the technique and the size of the original defect. Your surgeon will recommend the approach based on the size of the gap, your overall health, and whether you’ve had a hernia repair before.
Recovery After Surgery
Recovery depends on which approach your surgeon used. After laparoscopic repair, most people can return to normal daily activities within a few days and are back at work within one to two weeks. Open repair takes a bit longer, with normal activities resuming by about the sixth or seventh day and a typical return to work within four to six weeks.
Regardless of the approach, you should avoid lifting anything over 10 pounds and skip vigorous exercise until your follow-up appointment, which is usually a few weeks out. Full clearance for heavy lifting and intense workouts generally comes at four to six weeks. Some people feel well enough to return to a desk job within just a few days of either procedure.
Reducing Your Risk of Recurrence
Losing weight before surgery makes a meaningful difference. Bringing your BMI below 30 before the procedure lowers the risk of surgical site infections and other complications. If you smoke, quitting at least four weeks before surgery also reduces complication rates. After repair, managing the factors that caused the hernia in the first place, such as maintaining a healthy weight, treating chronic constipation, and using proper lifting technique, helps keep it from coming back.
