The most common symptom of an upper abdominal hernia is a small, visible bulge between your breastbone and belly button that appears when you stand, cough, or strain. Depending on the type of hernia, you may also experience pain at the bulge site, heartburn, or no symptoms at all. Upper abdominal hernias fall into two main categories: epigastric hernias, which push through the abdominal wall, and hiatal hernias, where part of the stomach slides upward through the diaphragm.
Epigastric Hernia Symptoms
Epigastric hernias develop in the upper middle section of your abdomen, in the strip of tissue running from your breastbone down to your belly button. They’re typically small, often less than half an inch (about 1 centimeter), roughly the length of a staple. Larger ones can reach about 1.5 inches, or walnut-sized, but that’s less common.
The hallmark symptom is a bulge you can both see and feel. It tends to appear when you’re standing and may disappear when you sit or lie down. You’ll likely notice it most during moments of increased abdominal pressure: lifting something heavy, coughing, sneezing, laughing, straining during a bowel movement, or bending over. The bulge pops out because that pressure pushes fatty tissue or, less commonly, a small piece of intestine through a weak spot in the abdominal wall.
Pain is the other major symptom. Unlike some conditions that cause a similar-looking bulge, epigastric hernias often hurt at the site of the protrusion. The pain can range from a dull ache to a sharper, more noticeable discomfort, and it typically worsens with the same activities that make the bulge more visible. Some small epigastric hernias cause no symptoms at all and are discovered incidentally during an exam or imaging for something else.
Hiatal Hernia Symptoms
A hiatal hernia is different in both location and presentation. Instead of pushing through the front of your abdominal wall, part of the stomach slides upward through the hiatus, the opening in the diaphragm where your esophagus passes through. Because this happens inside the body, there’s no visible bulge on the outside.
Most small hiatal hernias cause no symptoms. Larger ones, however, produce a distinctive set of problems centered on acid reflux:
- Heartburn, often the most prominent symptom
- Regurgitation, where swallowed food or liquid flows back into the mouth
- Trouble swallowing
- Chest or abdominal pain
- Feeling full unusually quickly after eating
- Shortness of breath
Because the symptoms overlap heavily with gastroesophageal reflux disease (GERD), many people with a hiatal hernia assume they simply have chronic acid reflux. The two conditions are closely linked, and a hiatal hernia can make reflux significantly worse by displacing the valve that normally keeps stomach acid from backing up into the esophagus.
What Makes Symptoms Worse
Both types of upper abdominal hernia share a common trigger: anything that increases pressure inside your abdomen. For epigastric hernias, that means heavy lifting, straining during bowel movements, persistent coughing or sneezing, and physical exertion. Chronic constipation and conditions like allergies or a lingering cough can keep that pressure elevated over time, making symptoms more frequent.
For hiatal hernias, large meals, lying down after eating, and bending forward can all push stomach contents upward and intensify reflux symptoms. Excess body weight adds constant abdominal pressure that aggravates both types.
Epigastric Hernia vs. Diastasis Recti
A condition called diastasis recti can look a lot like an epigastric hernia. It’s a separation of the muscles running down the center of the abdomen, and it also creates a bulge in the upper belly that appears when you sit up, cough, or lift. It’s especially common after pregnancy.
The key difference is pain. Hernias often cause noticeable pain at the bulge site because tissue is being squeezed through a hole in the abdominal wall. Diastasis recti may feel uncomfortable and weak, but it generally isn’t painful in the same way. A hernia bulge can also be visible while you’re resting, whereas a diastasis recti bulge typically only appears when the abdominal muscles are actively engaged, like sitting up from a lying position. A physical exam can usually distinguish between the two, though ultrasound or CT imaging confirms the diagnosis when it’s unclear.
Warning Signs of a Strangulated Hernia
Most epigastric hernias stay small and manageable, but any hernia carries a risk of strangulation. This happens when the tissue pushing through the abdominal wall gets trapped and its blood supply is cut off. It’s a medical emergency.
The signs are distinct from everyday hernia discomfort: sudden, severe pain that doesn’t let up and keeps getting worse, nausea and vomiting, and visible skin color changes around the bulge. The skin may first look paler than normal, then turn reddish or darker. If the bulge that you could previously push back in suddenly becomes firm and won’t go back, that’s a red flag. These symptoms warrant a call to 911.
How Upper Abdominal Hernias Are Diagnosed
A doctor can often identify an epigastric hernia during a physical exam by asking you to stand, cough, or bear down while they feel the abdominal wall. For confirmation or when the diagnosis is uncertain, imaging fills in the gaps. CT scans are highly accurate for abdominal wall hernias, with one study showing 100% sensitivity and positive predictive value for certain hernia types. Ultrasound performs well too, with sensitivity above 90% in most studies, and it has the advantage of being done in real time while you strain or change position.
Hiatal hernias are typically found during an upper endoscopy or a barium swallow X-ray, often while investigating reflux symptoms.
Treatment and Recovery
Asymptomatic epigastric hernias don’t always need surgery right away. A watchful waiting approach, where you monitor for changes, is considered reasonable for hernias that aren’t causing pain or growing. Current European and American hernia guidelines recognize this as a legitimate strategy for small, symptom-free hernias.
When surgery is recommended, the repair is typically straightforward. Smaller defects are often closed with sutures, while larger ones may require a mesh patch. Laparoscopic (minimally invasive) repair is generally reserved for bigger defects or patients at higher risk of wound complications. Most people return to comfortable daily activity within one to three weeks. Lifting anything over 10 pounds is restricted for at least six weeks, and complex or repeat repairs can carry lifting limitations for up to six months. Expect to feel groggy for two to three days after surgery from anesthesia and pain medication.
Hiatal hernia treatment focuses first on managing reflux symptoms through dietary changes and acid-reducing medications. Surgery is typically reserved for large hiatal hernias or cases where symptoms don’t respond to other measures.
