<s>[INST] My hubby (who is quite medically fit, 5'11", and weighs 11 and a half stone) is due for groin hernia op 3 weeks before going on hols in the Gran Canaria.  will he be able to swim IN THE SEA AND IN THE POOL?  He actually feel it's not worth going away if he can't, but we do need to be certain he'll be okay to do so.  Thanks! [/INST] Hi thnak you for querry.in case of inguinal hernia it depends either it is direct or inderect and if indirect complete or incomplete.The only compication occur if he do exercise,strenous work or swimming the hernia may strangulate its most common in indierect and complete hernia.if hernia goes back easily when he lies down than no need to worry for swimming.hope the answer will help you for making decision. </s>
