Hello,I'm new to this forum.My husband has had whipple operation for ampullary cancer,fortunately they caught it all and he has been informed he does not need chemo etc.The problem is that he is still in constant pain after 5 weeks of the operation ,he spent 4 week in hospital with delayed gastric emptying and lazy bowels.Now he is so tired with all the aching in his stomach and it feels bloated and tight.Does anyone else know how long this lasts for,also I understand he needs smaller meals but if he cant eat much due to discomfort,how will he put his weight back on,he lost 3 stone.
