Researchers have measured the nuchal folds of thousands of babies between 11 and 14 weeks of pregnancy. Because a babyâs nuchal fold will normally get a bit thicker with each day of gestation, theyâve been able to establish what an average thickness is for each day during those three weeks.
The Day of the Procedure. You should not eat any food on the day of the procedure, and you shouldn't eat or drink anything between two or three hours before your colonoscopy. Once the procedure is finished, your doctor will give you instructions about resuming your normal diet.
Re: Suggestions on what to eat before a colonoscopy. You can eat red meat. I wouldn't go OVERBOARD - mostly with the iron rich foods, they are talking about things like liver (yuck) and definately NO iron supplements. Red meat isn't the same as red dye - which is what they want you to avoid.
