I have recently had my gallbladder removed key hole. Three and a half weeks ago. No pain and wounds are healed. I have four incisions. One under my sternum, two under my ribs on the right hand side and the largest incision at the belly button 1.5 cm max. My surgeon was happy for me to do anything post operative. I mentioned diving and he gave me no restriction. Any advice appreciated. I have read some articles mentioning 4 or 6 weeks abstention from diving, but they don't state why. Would the main concern be lifting a heavy load in relation to risk of developing an incisional hernia? Thank you.
