What causes a groin hernia?

Hernias may be present at birth, or develop in later life as a result of any factor that weakens the tissues of the abdominal wall (e.g. inherited genetics, increasing age, smoking, increased pressure within the abdomen – long term cough, §sustained heavy lifting).

Usually the development of a hernia is a combination of these factors. There is no good evidence that occasional heavy lifting is a risk factor for developing a hernia.
