How many kind of hernias are?

There are several types of hernias, with the most common being inguinal, femoral, umbilical, and hiatal hernias. Inguinal hernias occur in the groin area, while femoral hernias appear just below it. Umbilical hernias occur around the belly button, and hiatal hernias involve the stomach pushing through the diaphragm. Other types include incisional hernias, which can occur at the site of a previous surgical incision.
