An untreated inguinal hernia may stay small for a while, but it usually does not heal on its own and can gradually grow or cause more discomfort. In some cases, tissue or part of the intestine becomes trapped, blocking the bowel or cutting off its blood supply. This is an emergency. Adults with little or no discomfort may sometimes choose monitored watchful waiting after discussing the risks with a clinician.
An inguinal hernia develops when tissue, such as fat or part of the intestine, pushes through a weak area in the lower abdominal wall near the groin. Leaving it untreated does not automatically lead to a serious complication, but the opening generally will not close on its own. The possible consequences depend on the hernia's symptoms, how it changes over time, and whether the tissue becomes trapped.
How can an inguinal hernia change over time?
An inguinal hernia may remain relatively small for some time, or the bulge may gradually become more noticeable. It can appear or become more prominent when standing, coughing, straining, or lifting something heavy. As it grows, the hernia may place more pressure on nearby tissues and make everyday activities less comfortable. According to the Mayo Clinic, most inguinal hernias enlarge over time if they are not repaired, and larger hernias in men can extend into the scrotum, causing pain and swelling.
Changes that may occur as a hernia progresses include:
- A groin bulge that becomes larger or more noticeable.
- A feeling of pressure, heaviness, burning, or aching in the groin.
- Discomfort that increases with coughing, prolonged standing, straining, or lifting.
- In men, swelling or discomfort that extends into the scrotum.
- Increasing difficulty carrying out usual activities because of discomfort.
These changes do not follow the same pattern in everyone. Some people have few symptoms, while others experience increasing discomfort. A hernia that becomes painful, enlarges, or interferes with daily activities should be reviewed by a healthcare professional to discuss whether repair is appropriate.
What complications can develop if a hernia is not repaired?
1. The hernia may become trapped
One possible complication is an incarcerated hernia, which means the tissue protruding through the abdominal wall becomes stuck and cannot move back into the abdomen. If the hernia contains part of the intestine, the trapped section may block the normal passage of intestinal contents. This can cause abdominal pain, swelling, nausea, vomiting, and difficulty passing stool or gas. The National Institute of Diabetes and Digestive and Kidney Diseases explains that a trapped hernia can progress to a more dangerous complication if its blood supply becomes restricted.
2. Blood flow to the trapped tissue may be cut off
A strangulated hernia occurs when the blood supply to trapped tissue is cut off. Without enough blood, the affected tissue may begin to die. If part of the intestine is involved, this can lead to serious bowel damage and other life-threatening complications. A strangulated hernia requires emergency surgery. The Cleveland Clinic identifies strangulation as a medical emergency because loss of blood flow can cause tissue death and potentially fatal complications.
Not every untreated hernia becomes trapped or strangulated. However, these complications can develop unexpectedly, and it is not possible to predict the course of every hernia from its size or the amount of discomfort it causes.
When should an inguinal hernia be treated as an emergency?
Seek emergency medical care if a suspected or known hernia is accompanied by warning signs such as:
- Sudden, severe, or rapidly worsening pain in the groin or abdomen.
- A bulge that becomes firm, very tender, or no longer moves back inside as it previously did.
- Red, purple, or unusually dark skin over the bulge.
- Nausea or vomiting, particularly with abdominal pain.
- Abdominal swelling or an inability to pass stool or gas.
- Fever along with a painful or changing hernia.
These symptoms may indicate that the hernia is trapped, that the intestine is blocked, or that blood flow has been affected. They are not suitable for home monitoring. Go to an emergency department immediately rather than waiting for a routine appointment. Do not try to force a painful or stuck bulge back into place.
Can an inguinal hernia be left alone if it does not hurt?
Sometimes, yes. For an adult man with an inguinal hernia that causes few or no symptoms, a clinician may recommend watchful waiting rather than immediate surgery. The Mayo Clinic explains that observation may be appropriate when a hernia is small and is not causing problems. However, painful or enlarging hernias usually need surgical repair.
Watchful waiting does not mean ignoring the hernia indefinitely. It involves an agreed plan with a healthcare professional, follow-up as advised, and attention to changes in pain, size, or function. The American College of Surgeons recognizes watchful waiting as an option for adults with an asymptomatic inguinal hernia. The decision should consider the person's symptoms, overall health, medical history, and preferences, along with the potential benefits and risks of surgery.
During follow-up, the healthcare professional can reassess the hernia and discuss whether repair is becoming more appropriate. New or worsening discomfort, an enlarging bulge, or difficulty with routine activities may change the management plan. If emergency warning signs appear, do not wait for the next scheduled review.
Does the advice differ for babies and children?
Yes. The watchful-waiting approach used for some adult men should not automatically be applied to children. Inguinal hernias in children are generally referred for surgical assessment and repair because trapped tissue can cause complications. The American Academy of Pediatrics describes inguinal hernias as a common pediatric surgical condition and explains that the risk of incarceration influences the timing of repair. The timing may need individual planning in premature infants or children with other medical concerns.
If a baby or child has a suspected groin hernia, arrange prompt medical assessment rather than waiting to see whether it disappears. A painful or stuck bulge, vomiting, skin color changes, or other signs of a possible complication require emergency evaluation.
What should you do if you are delaying hernia surgery?
If a healthcare professional has recommended observation, follow the agreed review schedule and ask what changes should prompt an earlier appointment. Discuss any increase in discomfort, changes in the bulge, or new problems with daily activities. It may also help to ask how your other health conditions affect the timing and risks of repair.
Do not assume that the absence of pain means the hernia has healed. A hernia may remain painless while the opening in the abdominal wall persists. Surgery is the usual way to repair that weakness, while observation can be reasonable for selected adults after an individualized discussion. The appropriate choice depends on the person's circumstances and the healthcare professional's assessment.
