A hernia occurs when an abnormal protrusion of an organ occurs through the cavity wall containing it. This may be either through a weakness in the cavity wall or via natural opening.

The most common hernia is the inguinal hernia, which makes up 75% of all abdominal hernias) Inguinal hernias are a protrusion of the contents of the abdominal cavity through the inguinal canal. Mild pain or discomfort in the region overlying the hernia is a common symptom. It can sometimes be very painful as part of the blood supply to the herniating organ is partially occluded.

Inguinal hernias can be detected clinically or by ultrasound, however tenderness around the area and sharp pains when coughing or during bowel movements is also indicative of inguinal hernias being present.

Other hernias, such as femoral, umbilical, incisional and diaphragmatic are less common but can be painful none-the-less and should be treated.

Treating hernias involves repairing the damaged cavity wall using keyhole surgery or an open incision. Both techniques employ usage of synthetic netting called ‘mesh’ to strengthen the repair and reduce chance of recurrent hernia formation.
There are several lifestyle factors that can cause a hernia to develop. These include:

Peritoneal Dialysis
Collagen Vascular Disease
Hernias can also be genetic.
