Brilliant paddyp and H12. Had my bypass four weeks ago today, and feel great. Witch - I had no pain post op, and was up in the chair the next day. The two weeks post op of 150ml per hour was a killer due to the heatwave, and knocked me for six. But not at all hungry. Now moving on to solids - feeling a tad cautious due to experiencing the predicted dreaded blockage last week caused by a tiny amount of scrambled egg made by someone other than me. It was not a good experience.
Going back to your original question, I moved to unlimited (within reason) fluids on Week 3.
I have lost over a stone post op, and two before on the liver shrinking. Was 118kg, 107kg on op day, and 99kg today. Am therefore no longer morbidly obese! Long may we continue to feel this great. x
