Umbilical Hernia Symptoms in Adults: Signs, Causes and Treatment

Medically reviewed by Dr. Alejandro López, FACS — Board-Certified General & Laparoscopic Surgeon

An umbilical hernia in adults shows up as a soft bulge at or near the belly button that often appears or grows when you strain, cough, stand, or lift something heavy. Unlike in babies, an umbilical hernia in an adult does not close on its own — surgical repair is the only definitive treatment.

If your belly button has started to pop out, feels tender, or you can feel a lump around your navel, you may have an umbilical hernia. This guide explains the symptoms to look for, what causes them in adults, the warning signs that mean you should seek care right away, and how the condition is treated.

What Is an Umbilical Hernia?

An umbilical hernia happens when tissue — usually fat, and sometimes a loop of intestine — pushes through a weak spot in the abdominal wall near the navel (belly button). The result is a visible or palpable bulge in the umbilical region.

In infants these hernias are common and frequently close by age 3–4. In adults, however, the abdominal wall opening will not heal by itself. Over time the gap tends to widen and the hernia slowly gets larger, which is why doctors evaluate adult umbilical hernias for repair rather than watchful waiting alone.

Common Umbilical Hernia Symptoms in Adults

The signs can be subtle at first and become more noticeable over months. The most common umbilical hernia symptoms include:

• A soft bulge or lump at or near the belly button that may enlarge when you stand up, cough, or bear down.
• Discomfort, pressure, or a mild aching around the navel, especially with exertion or after long periods on your feet.
• A bulge that flattens or disappears when you lie down and reappears when you stand (a “reducible” hernia).
• A feeling of heaviness or fullness in the lower abdomen.
• Skin over the bulge that looks stretched, or a belly button that has visibly “popped out.”

Many small umbilical hernias cause few symptoms at first. But because they don’t resolve on their own, keeping an eye on any change in size or new pain is important.

What Causes an Umbilical Hernia in Adults?

Adult umbilical hernias develop when repeated or sustained pressure inside the abdomen pushes against a naturally weaker area of the abdominal wall. Common contributing factors include:

• Being overweight or a significant change in weight
• Pregnancy (especially multiple pregnancies)
• Heavy lifting or straining, including at work or the gym with poor technique
• A chronic cough or long-term constipation
• Fluid build-up in the abdomen (ascites)
• Previous abdominal surgery near the navel

Fat-Containing vs. Small Umbilical Hernias

Not all umbilical hernias are the same. A fat-containing umbilical hernia holds only fatty tissue (omentum) and is often the earliest, smallest form — it may feel like a firm little knot. A small umbilical hernia can still be repaired with a quick, minimally invasive procedure, and repairing it while it’s small is usually simpler than waiting until it enlarges or a loop of bowel becomes involved.

Do Umbilical Hernias Go Away on Their Own?

In adults, no. There is no exercise, belt, or medication that closes the defect in the abdominal wall. Symptoms may come and go, but the underlying opening remains and typically enlarges. The only way to permanently fix an adult umbilical hernia is surgical repair.

How Is an Umbilical Hernia Diagnosed?

Most umbilical hernias are diagnosed with a simple physical exam — your surgeon feels the bulge and may ask you to cough or stand. When needed, an abdominal ultrasound or CT scan confirms the diagnosis, measures the defect, and shows whether fat or bowel is involved. This helps plan the right repair for you.

Treatment: Umbilical Hernia Repair Surgery

Umbilical hernia repair closes the abdominal-wall defect and reinforces it, usually with a lightweight surgical mesh. It can be performed two ways:

1. Laparoscopic repair — a few tiny incisions, less post-operative pain, and a faster return to normal activity.
2. Open repair — a small incision near the navel, often an option for smaller hernias and typically done on an outpatient (same-day) basis.

Most patients go home the same day and return to light activity within one to two weeks. Learn more about the procedure on our umbilical hernia surgery page.
