A hernia is defined as the protusion of abdominal contents through a defect in the abdominal wall.
It is generally as a result of a previous incision on the abdomen due to previous surgery and this is the commonest hernia seen.
A hernia can also arise around the umbilicus and in the groin, particularly in men due to ‘congenital’ weaknesses – weaknesses from birth.
Most hernia repairs are undertaken by the use of mesh as mesh is used to reinforce the repair. Mesh is generally regarded as safe but like any prosthethic material used in surgery such as new knees and hips, there is always a small risk with chronic pain and infection – for more advice on mesh please visit the British Hernia Society website https://mailchi.mp/23a275fbe343/j114lk1gnu
