S4-I don't know what all happened during your friends colonoscopy, but when anything is found during one of those (and often they do find polyps that are likely to become cancerous eventually) a person is advised to not do anything strenuous at ALL the day of it, and to keep things very easy for a few days afterward-particularly if anything at all was removed. Since so many of us are having them now (my husband has had a few)it is good to be on the cautious side. This is a surgical procedure, and people these days seem to think 'outpatient procedures' are simple and not any kind of issue. PLEASE don't take these procedures lightly. Women who had babies used to be kept in the hospital for a week or more. Now they send one home 24 hours after a c-section. That doesn't mean a person should assume they are good to go. Take it easy-cleaning halls and stadiums a couple days after such a medical procedure is NOT a good thing to do.
I am not a medical person-just a person who has had enough 'procedures' that it should count for something!
