Hernia

A hernia is when an internal part of the body, such as part of the bowel or fatty tissue, pushes through a weakness in the muscle or tissue wall around it. It often shows as a lump in the tummy or groin that may disappear when you lie down. Common types include inguinal, femoral, umbilical, incisional and hiatus hernias.

What it is

Some hernias cause no symptoms and only need monitoring. Others are repaired with surgery, often keyhole surgery.

A hernia can become stuck and cut off its blood supply (strangulated), which is an emergency.

Common signs

  • A lump or swelling in the tummy or groin
  • A lump that goes away when lying down
  • Aching or discomfort, especially when lifting or coughing

How it is usually diagnosed

  • Examination
  • Ultrasound or CT scan, sometimes

Records worth keeping

Keeping these together makes each appointment easier, especially when you see a new doctor:

  • Scan reports
  • Surgeon letters and operation notes
  • Discharge letters

Questions to ask your doctor

  • What type of hernia do I have?
  • Does it need surgery?
  • What should I avoid while I wait?

When to get help right away

Call 112 or go to the nearest emergency department if you have:

  • A hernia that becomes painful, hard or cannot be pushed back, with vomiting or not passing wind or poo: go to the emergency department or call 112
