- Why might the healing of wounds present problems in individuals with a very fatty abdominal
wall?

Q
- What is a hernia? What are the common sites for hernia due to the weakness of the abdominal
wall?
A
- Hernia is a protrusion of the abdominal contents (e.g. a loop of intestine or a piece of
omentum) through a gap or weakness in the abdominal wall. The common site for hernia in
males is the inguinal region resulting in the inguinal hernia, and in females the femoral region
resulting in femoral hernia. Others are the umbilical hernia, the hiatal hernia etc.
