A hernia is a defect between the muscles of the abdominal wall, resulting in a bulge.
There are three common types of hernias:
1) Umbilical hernia: Located at the belly button where it appears as a round lump of fat pushing the belly button outward. This is one of the most common hernias.
2) Inguinal hernia: In this type of hernia the bulge appears in the groin, and it is more common in men than in women.
3) Femoral hernia: This type of hernia is more common in women than in men. The hernia normally appears below the groin as a fixed lump.
