What is an umbilical truss?

Hernia Belt. Hernias are holes in the abdominal wall thru which the body creates a balloon-like sac; internal organs can get stuck in these, leading to serious problems. A truss may be worn to try and cover the hole from the outside to temporize matters. This is relatively ineffective due to the difficulty of keeping it in place. If one is healthy and the hernia is large, surgery is a better option.
