thank you so much-  I am scheduled to have a colonoscopy tomorrow and felt ill yesterday and today with headache, sore throat, and just generally feel ill-  I have been fasting all day today (except for liquids) and remember the nurse telling me to go ahead with the colonoscopy if I am ill.What is your opinion?Again, thank you.Nancy
Hi, Thanks for writing in. A colonoscopy is an office procedure to visualize the large bowel for any problem areas. This is done under anesthesia and your doctor will prescribe a course of antibiotics to avoid infection. Since you have a headache and sore throat therefore you might have got the flu. A flu happens due to infection with the virus causing common cold. This might stay for 3 to 5 days and make you feel weak. This is not a serious concern, but you should continue taking fluids and healthy food after the colonoscopy is done. Please be sure to inform the doctor about your feeling unwell and this will help the doctor to quickly assess your clinical situation with the least discomfort and pain. If your symptoms worsen then the colonoscopy might be rescheduled after a week when you feel better. Please do not worry.
