The most telling sign of an umbilical hernia is a soft bulge on or near your belly button, where a small loop of intestine or fatty tissue pushes through a weak spot in your abdominal wall. The bulge may be visible all the time, or it may only appear when you cough, strain, or lift something heavy. If you can see or feel a swelling right at your navel that wasn’t there before, there’s a good chance you’re dealing with an umbilical hernia.
What the Bulge Looks and Feels Like
An umbilical hernia typically shows up as a rounded swelling centered on or just beside the belly button. When you press on it gently, it usually feels soft rather than firm, and in many cases you can push it back in. That’s called a “reducible” hernia, meaning the tissue slides back through the opening when the pressure is off. Some people notice the bulge shrinks or disappears entirely when they lie flat on their back, then reappears when they stand up or tighten their core.
Not every hernia is obvious at rest. You might only notice yours during moments that increase pressure inside your abdomen: bearing down during a bowel movement, coughing, sneezing, or picking up something heavy. If you suspect a hernia but can’t see anything while relaxed, try standing in front of a mirror and gently contracting your abdominal muscles or coughing. This is essentially what a doctor would ask you to do during an exam. If a small mound pops out near your navel, that’s a strong indicator.
Pain and Other Symptoms
Many umbilical hernias cause no pain at all, especially small ones. You might feel a dull ache or pressure around your belly button, particularly after standing for a long time, exercising, or lifting. The discomfort tends to get worse with activity and ease up when you lie down.
Certain activities put extra strain on your abdominal wall and can make symptoms flare. Chronic coughing, prolonged constipation, heavy weightlifting, and straining during childbirth all increase pressure in the abdomen. If you notice your belly button area bulges or aches more during these moments, that pattern itself is a useful clue. Some people also feel a pulling or tugging sensation around the navel when bending or twisting.
How It Differs From Diastasis Recti
If you’ve been pregnant or gained significant weight, you may wonder whether the bulging you see is a hernia or diastasis recti, a separation of the abdominal muscles that runs vertically down the midline. The key difference is shape, location, and pain. Diastasis recti typically creates an oval-shaped ridge between the breastbone and belly button, visible when you do a crunch-like motion. It causes weakness but usually not pain.
An umbilical hernia, by contrast, is a distinct, localized bulge right at the navel. Hernias are more likely to cause pain at the site of the bulge. If you feel a focused, soft lump at your belly button that you can push back in, that points toward a hernia rather than muscle separation. Both conditions can exist at the same time, so one doesn’t rule out the other.
Umbilical Hernias in Babies
Umbilical hernias are common in newborns, especially premature babies. In infants, the classic sign is a belly button that puffs out when the baby cries, coughs, or strains, then flattens when the baby relaxes or lies on their back. The swelling is soft and painless, and parents often notice it during a particularly intense crying episode.
Most infant umbilical hernias close on their own by age 4 or 5 as the abdominal muscles strengthen. Surgery is more likely to be recommended if the hernia is larger than about 2 centimeters (roughly three-quarters of an inch) or hasn’t closed by school age. A hernia that doesn’t bother your baby and can be gently pushed back in is generally not an emergency, but one that becomes hard, discolored, or causes your baby obvious distress needs immediate medical attention.
Who Is Most at Risk
In adults, umbilical hernias develop when the abdominal wall weakens around the navel. Several factors raise your risk. Carrying excess weight puts constant pressure on that weak point. So does fluid buildup in the abdomen (common with liver disease), a chronic cough, repeated heavy lifting, or straining from prolonged constipation or an enlarged prostate. Pregnancy is another major contributor, especially multiple pregnancies, because the abdominal wall stretches repeatedly. Ultrasound studies have found umbilical hernias in roughly 25% of the adult population, so they are far more common than most people realize.
How Doctors Confirm It
The diagnosis is primarily based on a physical exam. Your doctor will look at your belly button, ask you to stand, and have you cough or tighten your abs to make the bulge more visible. In most cases, that’s enough for a definitive answer.
Imaging comes into play when the exam is inconclusive. An ultrasound is the first-line option because it’s quick, painless, and inexpensive. It can confirm whether tissue is poking through the abdominal wall. However, ultrasound is less reliable in people with larger hernias or significant obesity, and accuracy depends on the skill of the technician. If more detail is needed, a CT scan provides a clearer picture of the hernia’s size, borders, and contents, and can reveal whether anything else is going on inside the abdomen.
Warning Signs That Need Urgent Care
Most umbilical hernias are harmless and progress slowly, but a small percentage become trapped or strangulated. This means the tissue poking through the opening gets stuck and its blood supply gets cut off. It’s a surgical emergency.
Watch for these red flags: the bulge suddenly becomes painful or very tender, it turns red, purple, or dark, you can no longer push it back in, or you develop nausea and vomiting alongside the pain. A hard, tender lump at your belly button that won’t flatten when you lie down is not something to wait on. These signs suggest the hernia contents are trapped, and the tissue can begin to die without prompt treatment.
What Happens After You Spot It
If you’ve identified a soft, painless bulge at your navel that comes and goes with pressure, you likely have an umbilical hernia. Small hernias that cause no symptoms often don’t require immediate treatment, though they do tend to grow over time rather than resolve on their own in adults. Surgery is the only definitive fix, and it’s one of the most common and straightforward hernia repairs performed. Recovery typically takes a few weeks, with restrictions on heavy lifting during that time.
For now, the most useful thing you can do is pay attention to the bulge’s size, whether it’s changing, and whether it causes pain. Avoid straining with heavy loads when possible, and address underlying issues like chronic constipation or a persistent cough that keep pushing against the weak spot. Knowing what you’re looking at is the first step, and the physical signs of an umbilical hernia are distinct enough that most people can identify one at home with reasonable confidence.
