Umbilical Hernia in Adults: When Does It Need Repair?

By Dr. Richard Nguyen, DO, FACS, FACOS | Board-Certified Surgeon | San Jose & Los Gatos, CA

One of the most common questions I hear in my San Jose and Los Gatos offices is some version of this: "I have a bulge at my belly button, it doesn't really hurt, and my primary care doctor said we could watch it. Do I actually need surgery?" Umbilical hernias in adults are extremely common, and the honest answer is that not every one of them needs to be repaired right away. Deciding when to operate depends on your symptoms, the size and shape of the defect, and your individual health picture. This guide walks through how surgeons actually make that call, so you can have a more informed conversation about umbilical hernia repair in San Jose.

What an Umbilical Hernia Actually Is

The belly button is a natural weak point. It is where the umbilical cord passed through the abdominal wall before birth, and the fascia there closes over but never becomes as strong as the surrounding tissue. When that closure stretches or separates in adulthood, fat from inside the abdomen — and sometimes a loop of intestine — can push through the opening. That is what creates the visible bulge.

Adult umbilical hernias are not the same as the infant version. In babies, most close on their own during the first few years of life. In adults, they do not close spontaneously and they tend to enlarge slowly over time as abdominal pressure works against the defect. Common contributors include:

• Obesity and rapid weight gain
• Pregnancy, particularly multiple pregnancies
• Chronic cough, including from smoking or untreated sleep apnea
• Chronic constipation or straining
• Heavy lifting, whether occupational or in the gym
• Fluid buildup in the abdomen from liver disease
• Prior abdominal surgery near the umbilicus

When Watchful Waiting Is Reasonable

Not every hernia is an emergency, and I do not push surgery on patients who do not need it. Observation is often a sensible choice when all of the following are true:

• The hernia is small and produces little or no discomfort
• It reduces easily — meaning the bulge flattens when you lie down or press gently on it
• It is not interfering with work, exercise, or daily activity
• You do not have a medical condition that raises the stakes if a complication occurs

If we choose observation, it should be active observation, not neglect. That means knowing the warning signs, avoiding the strain patterns that enlarge the defect, and coming back for reassessment if anything changes. Hernias that are watched should still be watched by someone.

Signs It Is Time to Repair

The balance tips toward surgery when the hernia starts costing you something — comfort, function, or safety. Reasons I typically recommend proceeding with repair include:

1. Pain or aching that is becoming routine. Discomfort with lifting, coughing, standing for long stretches, or at the end of the workday is a sign the defect is under real mechanical stress.
2. The bulge is getting larger. Enlargement is generally one-directional. A larger defect at repair often means a more involved reconstruction than a smaller one would have required.
3. It no longer flattens out. A hernia that stays firm and protruding even when you lie down may contain tissue that is becoming stuck.
4. Skin changes over the hernia. Thinning, discoloration, or irritation of the overlying skin is a signal that the tissue is being stretched to its limit.
5. It limits what you do. Avoiding the gym, modifying how you lift your kids, or changing how you dress is a legitimate reason to fix a hernia.

Warning Signs That Need Urgent Attention

A small percentage of umbilical hernias become incarcerated, meaning tissue gets trapped, or strangulated, meaning the trapped tissue loses its blood supply. Strangulation is a surgical emergency. Go to an emergency department if you develop:

• Sudden, severe, or rapidly worsening pain at the hernia
• A bulge that becomes hard and cannot be pushed back in
• Redness or a dark, dusky color over the bulge
• Nausea, vomiting, or inability to pass gas or stool
• Fever alongside any of the above

Small defects are not automatically safer here. A narrow opening can actually trap tissue more effectively than a wide one, which is one reason "it's only small" is not on its own a reason to ignore a symptomatic hernia.

How Repair Is Done

Umbilical hernia repair is usually an outpatient procedure. The right technique depends on the size of the defect, whether there is associated abdominal wall weakness such as diastasis recti, your body habitus, and whether this is a first repair or a recurrence. Broadly, the options are:

• Open primary (tissue) repair. A small incision at or near the umbilicus, with the defect closed using sutures. Best suited to genuinely small defects in appropriate candidates. For patients who prefer to avoid implanted material, we discuss non-mesh hernia repair options and where they are and are not a good fit.
• Open repair with mesh. Reinforcement with mesh reduces recurrence risk for larger defects, where suture repair alone carries a meaningfully higher failure rate.
• Laparoscopic or robotic repair. For larger defects, recurrent hernias, or when there is a broader abdominal wall problem to address, a minimally invasive approach allows precise mesh placement through small incisions. Robotic hernia repair gives excellent visualization and fine control of the abdominal wall closure.

Most patients go home the same day and return to desk work within one to two weeks, with lifting restrictions for four to six weeks depending on the repair. If you want a fuller picture of what the weeks after surgery look like, our hernia surgery recovery timeline breaks it down week by week. Individual results vary.

Things Worth Optimizing Before Surgery

Repair durability is not only about technique. Patients who stop smoking, get blood sugar under control, treat a chronic cough, and address significant obesity before an elective repair tend to do better. When someone has a large hernia and a BMI well into the obese range, it is sometimes reasonable to sequence weight loss first — a conversation I have often in Los Gatos. Individual results vary, and the right sequence is specific to you.

Frequently Asked Questions

Can an umbilical hernia heal on its own in an adult?

No. Unlike infant umbilical hernias, adult umbilical hernias do not close spontaneously. Exercise, binders, and abdominal strengthening can help you manage symptoms and may reduce strain, but they do not repair the fascial defect. Surgery is the only definitive treatment.

Is it safe to wait if my hernia doesn't hurt?

Often, yes — a small, easily reducible, painless umbilical hernia can reasonably be observed. What matters is that you know the emergency warning signs and have it reassessed if it grows or becomes uncomfortable. Waiting is a plan, not a decision to stop paying attention.

Will I still have a belly button after surgery?

In most repairs, yes. The umbilicus is typically preserved and repositioned so the appearance stays natural. In cases with a very large defect or thinned, compromised overlying skin, the reconstruction may look somewhat different, and we discuss that with you beforehand.

Does insurance cover umbilical hernia repair?

Umbilical hernia repair is a medically necessary procedure and is generally covered by commercial insurance, Medicare, and Medi-Cal when there is a documented hernia. Deductibles, coinsurance, and prior authorization requirements vary by plan, so our team verifies benefits before scheduling. You can contact our San Jose or Los Gatos office to start that process.
