The symptoms of umbilical hernia in adults are often easy to spot but just as easy to dismiss, since many people assume a small bulge near the belly button is nothing to worry about. An umbilical hernia occurs when a portion of tissue — usually fat or a loop of intestine — pushes through a weak spot in the abdominal wall near the navel (umbilicus). While umbilical hernias are common in infants, they also affect a significant number of adults. Recognizing the symptoms of umbilical hernia in adults matters because, unlike in children, adult umbilical hernias do not resolve on their own and can lead to serious complications if left untreated. This article is general health information, not medical advice, and is not a substitute for evaluation by your own clinician.
Whether you have noticed a new bulge near your belly button, are experiencing unexplained abdominal discomfort, or are trying to decide whether your hernia needs surgical repair, this guide walks you through the symptoms, risk factors, diagnosis, and treatment options for adult umbilical hernias — starting with the warning signs you should never ignore.
Call 911 or go to the nearest emergency department now if a belly-button (umbilical) hernia becomes a surgical emergency. Warning signs of a trapped (incarcerated) or strangulated hernia include: a bulge that is suddenly firm, very tender, and cannot be pushed back in; skin over the bulge that turns red, purple, or dark; severe or rapidly worsening abdominal pain; nausea and vomiting; fever; a fast heartbeat; and no bowel movement or inability to pass gas. A strangulated hernia cuts off the blood supply to trapped tissue and can become life-threatening within hours — do not wait to see if it improves.
Most adult umbilical hernias show up as a soft bulge near the belly button that may ache with activity and flatten when you lie down. They do not close on their own in adults and tend to grow, so most are eventually repaired — elective repair is safer than emergency surgery. Seek emergency care for a firm, painful, non-reducible bulge with redness or discoloration, nausea or vomiting, fever, or no bowel movements, which can signal incarceration or strangulation. This is general educational information, not medical advice; have any new or changing bulge evaluated by a clinician.
What Is an Umbilical Hernia?
An umbilical hernia develops at or near the umbilicus (belly button), where the umbilical cord was attached before birth. This area is a natural weak point in the abdominal wall, and various factors can cause the tissue to give way, allowing abdominal contents to protrude through the opening.
According to the National Library of Medicine, umbilical hernias account for roughly 6 to 14 percent of all abdominal wall hernias in adults. They are more common in women than in men, particularly in women who have had multiple pregnancies. Unlike infant umbilical hernias, which usually close on their own by about age three to four, adult umbilical hernias tend to enlarge over time and generally require surgical repair.
The hernia itself consists of a sac formed by the peritoneum (the lining of the abdominal cavity) that pushes through the fascial defect, potentially containing omentum (fatty tissue), bowel, or both. The size can range from less than one centimeter to quite large, and the contents can be reducible (able to be gently pushed back in) or incarcerated (stuck).

Common Symptoms of Umbilical Hernia in Adults
The symptoms of an umbilical hernia in adults can range from barely noticeable to significantly uncomfortable, depending on the size of the hernia and whether complications have developed.
Visible bulge near the navel: The most obvious and often the first symptom is a noticeable bulge or swelling at or near the belly button. It may be more prominent when standing, straining, coughing, or lifting, and may flatten or disappear when lying down. According to the Mayo Clinic, the bulge is typically soft and may be tender to the touch.
Pain or discomfort at the hernia site: Many adults experience a dull ache, pressure, or soreness at the site. The discomfort is often worse with activities that raise abdominal pressure, such as lifting, bending, coughing, or prolonged standing. Some people describe it as a dragging or pulling sensation.
Increased symptoms with activity: Physical activity, particularly movements that engage the core, tends to worsen symptoms. You may notice the bulge becomes larger and more uncomfortable during exercise, heavy lifting, or straining during bowel movements. The discomfort usually improves with rest and when lying flat.
Symptoms That May Worsen Over Time
Adult umbilical hernias are progressive, meaning they tend to enlarge gradually. As the hernia grows, symptoms often become more noticeable and bothersome.
Increasing size of the bulge: Over months to years, the fascial defect can stretch, allowing more tissue to herniate. What started as a small, barely noticeable bulge can grow to become prominent and cosmetically concerning.
Difficulty reducing the hernia: Initially, most hernias can be gently pushed back into the abdomen (reduced). Over time, adhesions can form between the hernia contents and the sac, making the hernia harder to reduce or completely irreducible. An irreducible but otherwise painless, soft hernia is not an emergency in itself, but it does indicate the hernia is progressing and that surgical consultation is advisable. Any newly stuck bulge that becomes painful, firm, or discolored is a different situation — treat that as an emergency (see the warning box above).
Skin changes over the hernia: The skin covering a large or long-standing hernia may become thin, discolored, or develop a rash from friction with clothing. In very large hernias, the skin can become damaged or ulcerated, creating additional complications.
Nausea and digestive discomfort: If the hernia contains bowel, you may have intermittent nausea, bloating, or changes in bowel habits. These symptoms may come and go depending on the position of the herniated bowel and can worsen after eating. Persistent nausea and vomiting with a painful, stuck bulge, however, points toward incarceration and needs urgent care.
Emergency Symptoms: Incarceration and Strangulation
The most serious complications of an umbilical hernia are incarceration and strangulation. Both require urgent medical attention, and strangulation is a true surgical emergency. These are the reasons doctors take even a “small” hernia seriously.
Incarcerated hernia: An incarcerated hernia occurs when the hernia contents become trapped in the sac and cannot be pushed back into the abdomen. Symptoms include a firm, tender bulge that does not change size with position, increasing pain at the site, nausea and vomiting, and abdominal distension. While not always immediately life-threatening, an incarcerated hernia requires urgent surgical evaluation because it can progress to strangulation.
Strangulated hernia: A strangulated hernia is a medical emergency. It happens when the blood supply to the trapped hernia contents is cut off, causing tissue death (necrosis). According to the Cleveland Clinic, signs of a strangulated hernia include severe, sudden pain at the site; the bulge turning red, purple, or dark; fever; a rapid heart rate; nausea and vomiting (sometimes with green/bilious or foul, fecal-smelling vomit); and an inability to pass gas or have a bowel movement. A strangulated hernia requires emergency surgery to prevent bowel death and potentially life-threatening infection. If you have these symptoms, call 911 or go to the emergency department immediately — do not try to force the bulge back in and do not wait to see if it resolves.
Risk Factors for Developing an Umbilical Hernia
Understanding the risk factors can help you stay more vigilant about monitoring for symptoms if you fall into a higher-risk category.
Obesity: Excess weight, particularly abdominal obesity, increases pressure on the abdominal wall and is one of the strongest risk factors for developing an umbilical hernia. Research indexed on PubMed also links obesity to a higher risk of hernia recurrence after surgical repair.
Pregnancy: Multiple pregnancies stretch and weaken the abdominal wall, particularly at the umbilicus, and the increased abdominal pressure during pregnancy can cause or worsen an umbilical hernia. Some women first notice the hernia during pregnancy, though elective repair is typically deferred until after delivery.
Ascites (abdominal fluid): Conditions that cause fluid to accumulate in the abdomen, such as liver cirrhosis, raise abdominal pressure and are strongly associated with umbilical hernia development. Hernias in patients with ascites carry a higher risk of complications and present unique surgical challenges, so these cases are managed carefully with a specialist.
Other risk factors include chronic coughing (from conditions like COPD or chronic bronchitis), heavy lifting or strenuous physical labor, straining during bowel movements due to constipation, and previous abdominal surgery near the umbilicus.
Diagnosis and When Surgery Is Recommended
Diagnosis of an umbilical hernia is usually straightforward and is often made through physical examination alone. Your healthcare provider will examine the bulge, assess whether it is reducible, and check for signs of incarceration. Imaging such as ultrasound or CT may be ordered to measure the fascial defect, determine the hernia contents, and plan surgery.
Surgery is generally recommended for adult umbilical hernias because they do not resolve on their own and tend to enlarge over time. The Society of American Gastrointestinal and Endoscopic Surgeons supports surgical repair for symptomatic hernias, enlarging hernias, and hernias with a defect larger than about one to two centimeters.
That said, the decision is individualized. For a very small, painless, and easily reducible hernia in a person who is a poor surgical candidate, a surgeon may reasonably recommend “watchful waiting” with clear instructions on the emergency warning signs. Because emergency repair of a strangulated hernia carries higher risks than planned surgery, most surgeons favor elective repair once a hernia is symptomatic or growing. When elective repair is considered, timing can often be chosen around your schedule and health — but any hernia that becomes acutely painful or stuck changes the conversation from elective to emergency.
Surgical options include open repair, which uses a small incision near the umbilicus and closure of the defect with or without mesh reinforcement, and laparoscopic (and increasingly robotic) minimally invasive repair using small incisions and a camera. Mesh reinforcement is commonly recommended for defects larger than about one to two centimeters and has been shown to significantly reduce recurrence. The choice of approach depends on the hernia size, your overall health, and surgeon expertise.
When to See a Doctor
See a healthcare provider if you notice a new or growing bulge near your belly button, if the bulge is becoming more painful or harder to push back in, if you are having nausea, vomiting, or changes in bowel function along with the hernia, or if you want to discuss surgical repair options. Even an asymptomatic umbilical hernia in an adult is worth a medical evaluation to establish its baseline size and set up a monitoring or treatment plan.
Seek emergency medical care immediately — call 911 or go to the ER — if the hernia becomes suddenly painful and hard, if the overlying skin changes color (red, purple, or dark), if you develop fever, nausea, or vomiting along with hernia pain, or if you cannot push the hernia back in and it is accompanied by increasing pain. These findings suggest incarceration or strangulation, which require urgent surgical intervention.
Frequently Asked Questions
Can an umbilical hernia go away on its own in adults?
No. Adult umbilical hernias do not resolve spontaneously. Unlike in infants, whose abdominal wall muscles continue to develop and can close the defect, adults lack this capacity for spontaneous closure. Without surgical repair, most adult umbilical hernias gradually enlarge over time, and the risk of complications increases as the hernia grows.
How long is recovery from umbilical hernia surgery?
Recovery depends on the surgical approach and the individual. After open repair, many people return to light activities within one to two weeks and resume full activity in about four to six weeks. Laparoscopic or robotic repair may allow a slightly faster return to activity. Your surgeon will give you specific restrictions on lifting and exertion, and most patients notice significant pain improvement within a few days.
Can I exercise with an umbilical hernia?
Light to moderate exercise is generally safe with a small, reducible umbilical hernia, but you should avoid heavy lifting, straining, and exercises that sharply increase abdominal pressure (such as heavy squats, deadlifts, or intense core work). Walking, swimming, and light cycling are usually well tolerated. Discuss your specific routine with your healthcare provider, since recommendations vary by hernia size and symptoms.
What happens if I do not get surgery for my umbilical hernia?
Without surgery, an umbilical hernia will likely grow larger over time and may become more symptomatic. The main risk of leaving it untreated is progression to incarceration and strangulation, which are surgical emergencies. Elective repair is safer and has better outcomes than emergency repair. While watchful waiting may suit very small, asymptomatic hernias in some patients, most surgeons recommend repair for adult umbilical hernias — a decision to make together with your surgeon.
Will the hernia come back after surgery?
Recurrence rates vary with the repair technique and individual factors. Primary suture repair (without mesh) has higher recurrence, particularly for larger defects. Mesh repair significantly reduces recurrence, often to below about 5 percent. Factors that raise recurrence risk include obesity, wound infection, chronic coughing, heavy lifting too soon after surgery, and poor wound healing. Maintaining a healthy weight and following post-operative instructions carefully helps minimize recurrence risk.
Key Takeaways
The symptoms of umbilical hernia in adults typically include a visible bulge near the navel, discomfort or pain that worsens with activity, and progressive enlargement over time. Unlike infant umbilical hernias, adult hernias do not close on their own and generally require surgical repair. The most serious complications — incarceration and strangulation — are medical emergencies that require immediate care, so learn the warning signs (a firm, painful, non-reducible bulge with redness or discoloration, nausea or vomiting, fever, or no bowel movements) and act on them without delay. If you have a bulge near your belly button, schedule a medical evaluation to determine the right course of action. Elective repair is safer and more predictable than emergency surgery, so addressing the issue proactively is strongly recommended. For more health information, explore our medical conditions guide.
