Hernia — Frequently Asked Questions

Answered by Prof. Dr. Zahid Mahmood — General, Laparoscopic & Laser Surgeon, Lahore.

Can a hernia go away on its own?

In adults, no. A hernia does not heal by itself and generally grows larger over time. The only permanent cure is surgical repair. (Small umbilical hernias in babies are an exception and often close on their own.)

Is a hernia dangerous?

Most hernias are not dangerous at first, but they can become so if the contents get trapped and the blood supply is cut off — a strangulated hernia, which is a life-threatening emergency. This risk is exactly why timely, planned repair is recommended.

Is hernia surgery painful?

Some discomfort is normal, but it is usually mild and well controlled with simple painkillers. Keyhole (laparoscopic) surgery in particular tends to cause less pain and a faster recovery.

How long does hernia surgery take?

A straightforward hernia repair usually takes under an hour, and most patients go home the same day or the next morning.

How soon can I return to work?

Many people with desk jobs return within about a week, especially after keyhole surgery. Those doing heavy physical work usually need four to six weeks before lifting heavy loads.

Which is better — open or laparoscopic (keyhole) repair?

Both are excellent. Laparoscopic surgery often means less pain and quicker recovery and is especially good for hernias on both sides or recurrent hernias. Open mesh repair is superb and can be done under local anaesthesia. The best choice depends on your specific hernia and health, decided together with your surgeon.

Is mesh safe?

For the great majority of patients, tension-free mesh repair is safe and is the main reason recurrence is now uncommon. As with any implant, a small number of patients can have problems, which are discussed honestly before surgery.

Will my hernia come back after surgery?

Recurrence is uncommon with modern mesh repair. Maintaining a healthy weight, avoiding straining, treating a chronic cough, and not smoking all help keep the repair strong.

Can I exercise after a hernia repair?

Yes. Light activity and walking are encouraged early on, and most people return to full exercise after about four to six weeks, on their surgeon’s advice.

Can both sides be repaired at the same time?

Yes. When groin hernias are present on both sides, they can often be repaired together, and keyhole surgery is particularly suited to this.

Can I drive after hernia surgery?

Not until you can perform an emergency stop comfortably and are off strong painkillers — often one to two weeks. Follow your surgeon’s advice.

Is a hernia linked to cancer?

No. A hernia is a mechanical problem of the muscle wall, not a cancer. Still, any new lump should be checked by a doctor to confirm what it is.

Can a belt or truss cure my hernia?

No. A truss only holds the bulge in temporarily; it does not repair the muscle. It is mainly used for patients who cannot have surgery.

Am I too old for hernia surgery?

Age alone is rarely a reason to avoid surgery. Repair can often be done safely under local or spinal anaesthesia, and treating the hernia prevents a dangerous emergency later.

When should I go to the hospital urgently?

Immediately if a hernia becomes suddenly painful, hard, and impossible to push back — especially with vomiting, a swollen abdomen, or an inability to pass wind or stool. These are signs of a strangulated or obstructed hernia.
