A Hernia is a weakness or split in the muscle wall of the abdomen which allows the abdominal contents (usually some part of the intestine) to bulge out. The bulge is particularly due to tension in the abdominal wall muscles that occurs when coughing, sneezing, straining or simply standing.
Types of Hernia:
- Umbilical hernia: These common hernias are often noted at birth as a protrusion at the belly button (the umbilicus). This is caused when an opening in the abdominal wall, does not close completely (which normally closes after birth) leading to hernia.
- Incisional hernia: Abdominal surgery causes a flaw in the abdominal wall that must heal on its own. This flaw can create an area of weakness where a hernia may develop.
- Obturator hernia: This extremely rare abdominal hernia happens mostly in women. This hernia protrudes from the pelvic cavity through an opening in your pelvic bone.
Any condition that increases the pressure of the abdominal cavity may contribute to the worsening of a hernia, such as obesity, heavy lifting, coughing, fluid in the abdominal cavity.
For hernia often a simple surgery is done.
