Periumbilical hernia, the adult bulge that rarely fixes itself.

Not the same as a baby’s umbilical hernia - in adults this weakness tends to grow rather than close, and mesh repair is usually the answer.

Key facts

Periumbilical hernia at a glance.

The essentials, in plain English - what it is, why adults differ from children, and how it’s treated in the UK today.

  • What it is

    A weakness at or near the umbilicus in adults, through which abdominal contents (fat or bowel) protrude as a bulge.

  • Not a child’s hernia

    Unlike the paediatric umbilical hernia, this adult version rarely closes on its own and usually needs surgery.

  • Common triggers

    Obesity, pregnancy, chronic straining, ascites and previous abdominal surgery all raise the risk.

  • Reducible vs stuck

    A reducible hernia goes back in with gentle pressure or lying flat - one that won’t is an emergency.

  • Main treatment

    Mesh repair is generally preferred over suture repair in adults, given its lower recurrence rate.

  • When to worry

    A hernia that becomes painful, tender, firm and non-reducible needs same-day emergency assessment.

Why this guide matters

Adults are not a bigger version of children.

It is tempting to assume a hernia near the belly button will behave like the one many babies grow out of. In adults it usually will not - and that changes the whole plan.

  • It rarely closes by itself

    Once the abdominal wall has matured, a periumbilical defect tends to persist and slowly enlarge rather than heal on its own.

  • Surgery is usually the destination

    For symptomatic or enlarging hernias, mesh repair is the standard route - watchful waiting suits only small, quiet ones.

  • Complications carry real urgency

    Incarceration and strangulation are surgical emergencies - recognising the signs early protects against a much bigger operation later.

How the diagnosis is made

From first bulge to a clear plan.

The steps a UK GP or surgeon will normally follow, in order - so you know what to expect and why.

  1. 01

    Assessing

    Clinical examination

    Most periumbilical hernias are diagnosed by look and feel alone - standing, lying and straining reveal the bulge and its size.

  2. 02

    Assessing

    Reducibility check

    The clinician assesses whether the contents slip back in easily, with difficulty, or not at all.

  3. 03

    Assessing

    Risk-factor history

    Weight, smoking, pregnancies, chronic cough, constipation and any ascites are reviewed - they shape both risk and surgical planning.

  4. 04

    Confirming

    Ultrasound or CT if uncertain

    Imaging is reserved for diagnostic doubt, a very large or complex hernia, or when planning repair in an obese patient.

  5. 05

    Confirming

    Surgical risk discussion

    Obesity and smoking both raise recurrence and wound-complication rates - discussed openly before listing for surgery.

  6. 06

    Preparing

    Shared decision on timing

    For small, symptom-free hernias, watchful waiting is a reasonable and safe choice, revisited if things change.

  7. 07

    Preparing

    Emergency pathway if incarcerated

    A painful, non-reducible, tender hernia bypasses routine referral and goes straight to emergency surgical assessment.

Typical timeline: a first assessment to a settled plan within a few weeks.

Symptoms

What a periumbilical hernia actually looks like.

A soft, often reducible bulge near the belly button - and the features that mean it’s time to escalate.

  • Visible or palpable bulge

    A soft swelling at or near the belly button, often more obvious when standing, coughing or straining.

  • More prominent on straining

    Lifting, coughing or a bowel movement can push the bulge out further and make it easier to see.

  • Reducible on lying flat

    In many people the bulge flattens or can be gently pushed back in when lying down and relaxed.

  • Dragging or aching discomfort

    A dull ache or dragging sensation around the umbilicus, worse by the end of the day or after activity.

  • Skin changes over the bulge

    Thinning, shiny or discoloured skin can develop over a long-standing or enlarging hernia.

  • Gradual enlargement over time

    Adult periumbilical hernias tend to grow slowly rather than resolve, unlike hernias in infants.

  • Association with ascites

    Fluid in the abdomen raises pressure on the wall and can rapidly enlarge or unmask a hernia.

  • Red flag - firm, tender, stuck

    A hernia that is suddenly painful, tender, firm and won’t reduce needs emergency assessment for incarceration.

Treatment

How periumbilical hernia is treated in the UK.

Watchful waiting for small, quiet hernias - mesh repair for symptomatic or enlarging ones, and emergency surgery when complications arise.

  • Watchful waiting

    Reasonable for small, symptom-free hernias - reviewed periodically with clear advice on what would prompt earlier surgery.

  • Mesh repair (open)

    The standard adult approach - a synthetic mesh reinforces the defect and lowers recurrence compared with suture-only repair.

  • Laparoscopic mesh repair

    A keyhole alternative for suitable patients, often with a faster return to normal activity.

  • Suture repair

    Occasionally used for very small defects, though recurrence rates are higher than with mesh.

  • Weight loss before surgery

    Reducing body weight improves healing, lowers recurrence and reduces anaesthetic and wound risk.

  • Smoking cessation

    Stopping smoking before elective repair meaningfully improves wound healing and surgical outcomes.

  • Managing ascites or cough

    Treating the underlying driver - liver disease, chronic cough or constipation - reduces the chance of recurrence after repair.

  • Emergency surgery

    Required urgently for incarceration or strangulation, to release trapped tissue and restore blood supply.

Red flags

When a periumbilical hernia needs urgent attention.

Most periumbilical hernias are manageable and can be planned around. These are the situations that aren’t - and where emergency care is needed.

  • Incarceration

    A hernia that is firm, tender and cannot be pushed back in is trapped and needs same-day surgical assessment.

  • Strangulation

    Severe pain, redness, fever or vomiting alongside a stuck hernia suggests the blood supply is compromised - a surgical emergency.

  • Bowel obstruction

    Colicky abdominal pain, distension, vomiting and no bowel motions can signal obstructed bowel within the hernia.

  • Rapid enlargement

    A hernia growing quickly over days or weeks, rather than months, warrants prompt review.

  • Skin breakdown or discolouration

    Thinning skin that becomes red, purple or breaks down over the hernia needs urgent attention.

  • New hernia with ascites

    A periumbilical hernia appearing alongside worsening ascites should prompt review of both the hernia and the liver condition.

  • Persistent vomiting

    Vomiting with a tender abdominal bulge is not something to sit on - seek same-day care.

  • High fever with abdominal pain

    Fever plus a painful hernia raises concern for strangulated or infected bowel and needs emergency review.

Living with it

A manageable condition, with a clear ladder.

Four things that make the biggest difference day to day - knowing your baseline, tackling contributing factors, preparing well for surgery, and acting fast if it changes.

A quiet reminder

A quiet hernia can turn noisy quickly.

Most periumbilical hernias behave predictably for years - but a sudden change in pain or reducibility is always worth same-day attention.

  1. 01 Monitor

    Know your baseline

    Get familiar with the size and feel of the bulge so you notice quickly if it changes, enlarges or becomes tender.

  2. 02 Reduce

    Address contributing factors

    Managing weight, treating chronic cough or constipation, and controlling ascites all lower the chance of the hernia worsening.

  3. 03 Prepare

    Optimise before surgery

    Losing weight and stopping smoking ahead of a planned repair genuinely improves healing and lowers recurrence.

  4. 04 Act fast

    Treat a stuck hernia as urgent

    Pain, tenderness and a bulge that won’t go back in is not something to wait out - seek same-day emergency care.

Frequently asked

Everything we get asked about periumbilical hernia.

Quick answers on causes, watchful waiting, mesh repair and emergency warning signs.

  • What is a periumbilical hernia?

    It is a hernia occurring at or near the umbilicus in adults, where fat or bowel pushes through a weakness in the abdominal wall. It is distinct from the umbilical hernias seen in babies, and behaves quite differently.

  • Will it heal on its own?

    Rarely. Unlike umbilical hernias in infants, which often close as the abdominal wall matures, adult periumbilical hernias generally do not resolve spontaneously and tend to enlarge slowly over time.

  • Do I need surgery straight away?

    Not necessarily. Small, symptom-free hernias can reasonably be watched and reviewed periodically. Surgery is generally recommended once a hernia becomes symptomatic, enlarging, or shows any sign of complication.

  • Why is mesh repair usually preferred?

    Mesh repair reinforces the abdominal wall defect and is associated with a lower recurrence rate than suture-only repair in adults, which is why it is the standard approach for most periumbilical hernias.

  • What increases my risk of this hernia?

    Obesity, pregnancy - especially multiple pregnancies - chronic straining from cough or constipation, ascites, and previous abdominal surgery are all recognised risk factors.

  • How do I know if it’s an emergency?

    If the bulge becomes painful, tender, firm to touch and cannot be pushed back in, this suggests incarceration or strangulation. This needs same-day emergency surgical assessment, not a routine appointment.
