Hernia

Understanding hernias, the symptoms, causes and how they are treated.

OVERVIEW

What is a hernia?

A hernia happens when an internal part of the body, usually part of the bowel or a piece of fatty tissue pushes through a weakness in the surrounding muscle or connective tissue wall. This weakness may be present from birth, may develop gradually with age, or may follow previous surgery, heavy lifting or persistent straining. The result is often a soft, visible lump that becomes more noticeable when standing, coughing or exerting effort, and which may ease or disappear when lying down. Hernias are extremely common, affecting people of all ages and both sexes, though certain types, such as inguinal hernias, are considerably more frequent in men. While most hernias are not immediately dangerous, they do not resolve without treatment and typically enlarge gradually over time, which is why an assessment is recommended as soon as a lump or discomfort is noticed, even if symptoms are currently mild.

TREATMENT OPTIONS

How a hernia can be treated

01

Watchful monitoring

Small, painless hernias may simply be monitored, with advice on symptoms to watch for.

02

Keyhole repair

Laparoscopic repair through small incisions, often allowing a quicker return to activity.

03

Open repair

A single incision to reinforce the area with a soft mesh for a durable, lasting repair.

When should you seek advice?

If a hernia becomes painful, grows larger or cannot be pushed back, seek advice promptly Mr Woodward offers assessment within 48 hours.

Common questions about hernias

Are hernias dangerous?

Most hernias are not dangerous, but they should be assessed as they can enlarge over time and occasionally lead to complications.

A hernia will not heal by itself, though small, symptom-free hernias may sometimes be safely monitored rather than operated on straight away.

Many patients return to desk-based work within a week or two, while physical jobs may need three to four weeks, depending on the repair performed.
