I hate to see a question go unanswered. I have not had this particular operation yet. I am scheduled for a sigmoid colectomy on April 1st. (Yep, I'm having surgery on April Fool's Day!) But I have had other major surgeries and it does not seem unreasonable to me that you are still feeling tired 2 weeks post-op. Your body has had a major trauma and is busy repairing the damage that was done to it. That takes energy and our bodies do tend to force us to rest after something like that to conserve energy for the healing process. Of course, if you are really concerned you should ask your Dr about it, but I'd say it's normal. What about those of you who HAVE had this surgery? What was yuor experience?
