Hernias: Complete Guide

A hernia occurs when an organ or tissue pushes through a weak point in surrounding muscle. Most are manageable, but strangulation is a surgical emergency.

Most common type
Inguinal (groin) hernia
More common in
Men (inguinal specifically)
Emergency sign
Strangulation — irreducible, painful, discoloured
Treatment
Usually surgical repair

Types of Hernia

TypeLocationNotes
InguinalGroinMost common — 75% of hernias, much more common in men
UmbilicalBelly buttonCommon in babies (often resolves); can occur in adults too
HiatalDiaphragm (stomach pushes into chest)Causes reflux symptoms; often doesn't need surgery
IncisionalAt site of previous surgeryWeakness at scar site
FemoralUpper inner thighMore common in women; higher strangulation risk

Symptoms

When It's a Surgical Emergency

SignMeaning
Irreducible (can't push back in)Incarcerated hernia — needs assessment
Severe pain, redness, firmnessPossible strangulation — blood supply cut off — surgical emergency
Vomiting, unable to pass stool/windPossible bowel obstruction from hernia
Strangulated Hernia — EmergencyA hernia that becomes suddenly painful, firm, red/discoloured, and can't be pushed back in may indicate strangulation (blood supply cut off) — this requires emergency surgery, as delay risks bowel death and life-threatening infection.
Not All Hernias Need Immediate SurgerySmall, asymptomatic hernias, particularly in older or higher-risk patients, may be monitored ('watchful waiting') rather than immediately operated on — discuss the right approach for your specific situation with a surgeon.
Can a hernia heal on its own without surgery?
No — hernias don't resolve spontaneously in adults (though umbilical hernias in babies often do close naturally). Surgery is the only definitive treatment, though timing depends on symptoms and risk.
What causes hernias?
A combination of weakness in the muscle wall (sometimes congenital) and increased pressure (heavy lifting, chronic cough, straining, obesity, pregnancy) contribute to hernia development.
