Meshes used for hernia repairs remain in the body indefinitely, according to the U.S. Food and Drug Administration. The mesh is either considered a permanent implant, or simply used as reinforcement until new tissue growth occurs to strengthen the repair.
Surgical, synthetic mesh is non-absorbable and will remain in the body permanently, states the U.S. Food and Drug Administration. Absorbable mesh, which is derived from animal tissues such as skin or intestine from a pig or cow, is not intended for long-term reinforcement. Absorbable mesh will eventually degrade, allowing new tissue growth to take over repair of the hernia site.
