How serious is a Hernia?

This link will shed some light in the subject. http://www.babycenter.com/0_hernias_1176787.bc?articleId=1176787&page=3#articlesection1

a hernia is the outpouching of the intestinal contents throughout a potential defect in the abdominal wall. if it reduces on lying down, then well and good. if irreducible, then it may be a cause of worry. small children of your daughter's age do suffer from this problem. it gets corrected as they grow up. but if there is recurrent pain and symptoms of fever or generalised body ache, do consult a surgeon for the hernia may have got strangulated. it may further lead to infection. so it is better to have a surgery done with meshplasty done to avoid recurrence. all the very best to the small child. may the lord be with her.

I am happy that you can see things with goggle.

That depends on how old the child is and where the hernia is located. My son gave himself a herna when he was only a few months old, but it wasn't causing him any pain and closed on its own, so it didn't require any surgery. A hernia is just where an organ protrudes through a tear in a membrane. My son's was a little piece of an intestine, which made his little belly button an outie. His pediatrician said that they were pretty common in babies his age, so not to worry about it, and she was right. He got his from throwing fits. He had screamed for 4 hours straight at 3 or 4 months old, then lost his voice for two weeks and got that hernia. So they can be serious without treatment, but since she's getting it operated on, I wouldn't worry too much. Just keep her from straining too much right now. Blessed Be

My daughter has the same issue now and tomorrow is her operation.
