The symptoms of umbilical hernia in adults are often easy to identify but just as easy to dismiss, since many people assume that 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 is important because, unlike in children, adult umbilical hernias do not resolve on their own and can lead to serious complications if left untreated.
Whether you have noticed a new bulge near your belly button, are experiencing unexplained abdominal discomfort, or are trying to determine whether your hernia needs surgical repair, this guide will walk you through the symptoms, risk factors, diagnostic process, and treatment options for adult umbilical hernias.
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 approximately 6 to 14 percent of all abdominal wall hernias in adults. They are more common in women than men, particularly in women who have had multiple pregnancies. Unlike infant umbilical hernias, which usually close spontaneously by age three to four, adult umbilical hernias tend to enlarge over time and 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 of the hernia can range from less than one centimeter to quite large, and the contents can be reducible (able to be 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. This bulge may be more prominent when standing, straining, coughing, or lifting heavy objects 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 with umbilical hernias experience a dull ache, pressure, or soreness at the site of the hernia. The discomfort is often worse with activities that increase abdominal pressure, such as lifting, bending, coughing, or prolonged standing. Some people describe the pain as a dragging or pulling sensation.
Increased symptoms with activity: Physical activity, particularly movements that engage the core muscles, 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 may 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 quite 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 hernia is not an emergency in itself but does indicate that the hernia is progressing and surgical consultation is advisable.
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 experience 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.
Emergency Symptoms: Incarceration and Strangulation
The most serious complications of an umbilical hernia are incarceration and strangulation, both of which require emergency medical attention.
Incarcerated hernia: An incarcerated hernia occurs when the hernia contents become trapped in the hernia sac and cannot be pushed back into the abdomen. Symptoms include a firm, tender bulge that does not change size with position changes, increasing pain at the hernia site, nausea and vomiting, and abdominal distension. While not immediately life-threatening, an incarcerated hernia requires urgent surgical evaluation because of the risk of progressing to strangulation.
Strangulated hernia: A strangulated hernia is a true surgical emergency. It occurs when the blood supply to the incarcerated hernia contents is cut off, causing tissue death (necrosis). According to the Cleveland Clinic, symptoms of a strangulated hernia include severe, sudden pain at the hernia site, the bulge becoming red, purple, or dark in color, fever, rapid heart rate, nausea and vomiting (especially bilious or fecal vomiting), and inability to pass gas or have a bowel movement. A strangulated hernia requires emergency surgery to prevent bowel death and potentially life-threatening infection.
Risk Factors for Developing an Umbilical Hernia
Understanding the risk factors can help you be 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. According to research in PubMed, obesity also increases the risk of hernia recurrence after surgical repair.
Pregnancy: Multiple pregnancies stretch and weaken the abdominal wall, particularly at the umbilicus. The increased abdominal pressure during pregnancy can cause or worsen an umbilical hernia. Some women first notice the hernia during pregnancy, though repair is typically deferred until after delivery.
Ascites (abdominal fluid): Conditions that cause fluid accumulation in the abdomen, such as liver cirrhosis, increase 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.
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 evaluate for signs of incarceration. Imaging studies such as ultrasound or CT scan may be ordered to assess the size of the fascial defect, determine the hernia contents, and plan for 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 recommends surgical repair for symptomatic hernias, enlarging hernias, and hernias with a defect larger than one to two centimeters.
Surgical options include open repair, which involves a small incision near the umbilicus and closure of the defect with or without mesh reinforcement, and laparoscopic repair, a minimally invasive approach using small incisions and a camera. Mesh reinforcement is recommended for defects larger than one to two centimeters and has been shown to significantly reduce recurrence rates. The choice of approach depends on the hernia size, patient factors, and surgeon expertise.
When to See a Doctor
You should see a healthcare provider if you notice a new or growing bulge near your belly button, if the bulge is becoming more painful or difficult to push back in, if you are experiencing nausea, vomiting, or changes in bowel function along with the hernia, or if you want to discuss surgical repair options. Even asymptomatic umbilical hernias in adults warrant a medical evaluation to establish baseline size and develop a monitoring or treatment plan.
Seek emergency medical care immediately if the hernia becomes suddenly painful and hard, if the overlying skin changes color (becomes red, purple, or dark), if you develop fever, nausea, or vomiting along with hernia pain, or if you are unable to push the hernia back in and it is accompanied by increasing pain. These symptoms 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, where the 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 will gradually enlarge over time, and the risk of complications increases as the hernia grows.
How long is recovery from umbilical hernia surgery?
Recovery time depends on the surgical approach and the individual. After open repair, most people can return to light activities within one to two weeks and resume full activity in four to six weeks. Laparoscopic repair may allow a slightly faster return to activity. Your surgeon will provide specific restrictions on lifting and physical activity during recovery. Most patients experience significant pain improvement within a few days of surgery.
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 significantly increase abdominal pressure (such as heavy squats, deadlifts, or intense core exercises). Activities like walking, swimming, and light cycling are usually well-tolerated. Discuss your specific exercise routine with your healthcare provider, as recommendations vary based on 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 primary risk of not treating an umbilical hernia is the potential for incarceration and strangulation, which are surgical emergencies. Elective repair is safer and has better outcomes than emergency repair. While “watchful waiting” may be appropriate for very small, asymptomatic hernias in some patients, most surgeons recommend repair for adult umbilical hernias.
Will the hernia come back after surgery?
Recurrence rates vary depending on the repair technique and individual factors. Primary suture repair (without mesh) has higher recurrence rates, particularly for larger defects. Mesh repair significantly reduces recurrence, with rates typically below 5 percent. Factors that increase the risk of recurrence include obesity, infection, chronic coughing, heavy lifting too soon after surgery, and poor wound healing. Maintaining a healthy weight and following post-operative instructions carefully can help 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 surgery. If you have a bulge near your belly button, schedule a medical evaluation to determine the appropriate 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.
