A hernia occurs when an internal part of the body pushes through the muscle or surrounding tissue wall, usually because it’s been weakened in some way. In many cases, it causes no or very few symptoms, although you may notice a swelling or lump in your tummy (abdomen) or groin. The lump can often be pushed back in or disappears when you lie down, and may appear again if you cough or strain. You may be referred to N2S for one of the following types of hernia: Inguinal hernias Inguinal hernias occur when fatty tissue or a part of your bowel pokes through into the top of your inner thigh. This is the most common type of hernia, although it mainly affects men. Femoral hernias Femoral hernias, similar to inguinal hernias, also happen when fatty tissue or part of your bowel pokes through into the top of your inner thigh. They’re much less common than inguinal hernias and tend to affect more women than men. Umbilical hernias Umbilical hernias occur when fatty tissue or part of your bowel pokes through your tummy near your belly button. This type of hernia can occur in babies if the opening in the tummy that the umbilical cord passes through does not seal properly after birth, however adults can also be affected. Each type of hernia is often associated with aging and repeated strain on the tummy. Surgery will get rid of the hernia and prevent any serious complications, although there is a chance of it returning after the operation. All operations at N2S are performed under local anaesthetic. We do not perform spigelian, ventral, incisional hiatus, laparoscopic or recurrent hernia repairs.
