Inguinal and umbilical hernias: what to know

A hernia is when an internal body component, often a part of an organ, starts to extrude through a weakness or fault in the muscle or tissue wall. They are most common in the torso, particularly the abdomen and groin areas. Some hernias can be left alone, but some will need medical intervention for the comfort and health of the patient. Two of the most common types are inguinal hernias and umbilical hernias. In this article, a consultant upper gastrointestinal and general surgeon explains the differences between the two and how they are treated.
