I also am not a doctor and can only tell you of my experience. I have had colonoscopies many times. Each time I was told that a pollop or two was removed. The last time was a little over a year ago. I never experienced any discomfort before or after and never had problems with my colon except that I always got diarrhea if I ate cashews and have been like that all my life even when I was a child. I am now 66 but the last colonoscopy caused me to hemmorage and I was admitted back to the hospital for overnite observation. Well, everything started happening immediately after that. I didn't feel well even though I remained on a soft diet. Finally, my thyroid readings went bizurk and I am now having severe headaches and can barely turn my neck. I have dizziness and am extremely tired. I had to give up my job because of lack of memory as well. My hearing has been affected. Don't let doctors or anyone tell you that all your symptoms are connected to old age. I'm not going to settle for that and I eventually will find out what the problem is. So, take care and I hope all turns out better for you. My next colonoscopy will be when I say I need it.
