Not all hernias stick out. Some have a bigger opening for the intestine to stick through. From my memory, the one's with the larger opening are better, because you can push them back. The one's that have a tiny opening can get stuck or strangulated easier making them more dangerous and more of an emergency situation. Don't be your own doctor Jump, okay? You only have this one body, take care of it.
In an inguinal hernia, the intestine or the bladder protrudes through the abdominal wall or into the inguinal canal in the groin. About 80% of all hernias are inguinal, and most occur in men because of a natural weakness in this area.
In an incisional hernia, the intestine pushes through the abdominal wall at the site of previous abdominal surgery. This type is most common in elderly or overweight people who are inactive after abdominal surgery.
A femoral hernia occurs when the intestine enters the canal carrying the femoral artery into the upper thigh. Femoral hernias are most common in women, especially those who are pregnant or obese.
In an umbilical hernia, part of the small intestine passes through the abdominal wall near the navel. Common in newborns, it also commonly afflicts obese women or those who have had many children.
