A hernia is where Innards protrude through a weakness in the outer covering. This could be anywhere, such as fat bulging through the muscle of the lower eyelid causing eyebags or most commonly bowel protruding through the abdominal wall
There are several different types of abdominal wall hernia, with the most common being Inguinal hernia, when part of the bowel squeezes through the lower abdomen into the groin. This is mainly associated in men with a weakness of the testicular canal and can be initiated by the repetitive strain of coughing raising pressure in the abdomen. Although most of these types of hernias are thought to be a result of ageing, they can occur at any age, even babies.
The muscles in the abdomen become weaker, making the chances of an Inguinal hernia more likely. The extra strain of carrying or lifting heavy weights increase pressure within the abdomen or a just a persistent cough is enough to create an inguinal hernia.
A hernia repair or removal surgery is recommended if you have troublesome discomfort or the contents of the hernia becomes stuck pain and will not reduce back into the abdomen. These are early symptoms of bowel obstruction and may lead on to nausea, vomiting and severe pain. Eventually, the blood supply to the bowel is cut off and an emergency surgery is required.
At this point, we should mention the separation of the rectus muscles during pregnancy termed Diastasis or divarication of the recti muscles. It often remains after pregnancy and causes the unsightly bulge as the stomach muscles are tensed. Fortunately, the complication of strangulation does not occur. We treat this on its own or part of an abdominal reduction (abdominoplasty).
Other types of hernia include:
+ Hiatus Hernia – when the part of the stomach pushes into the chest through the diaphragm causing indigestion + Spigelian hernia – part of the bowel pushes between the edge of the abdominal muscles, + Femoral hernia – part of the bowel pushes through below the groin, mostly in women. These strangulate easily and need urgent surgery. + Incisional hernia – tissue pushes through a weak surgical wound in the abdominal wall. + Epigastric hernia – part of the bowel or fatty tissue pushes through the centre of abdomen, below the breastbone. + Umbilical hernia – a common hernia of the tummy button in children or after the pressures of pregnancy.
It’s important to receive a medical diagnosis from a doctor if hernia is suspected.
