It is known that colonoscopy saves lives, but the preparation can be so unpleasant. I am so happy that researchers are working towards making it more tolerable so that more people will undergo the procedure that can save their lives. I am happy that many different options are available: not all involving colon cleansing (e.g. X-rays), that there is a dietary advice to minimize the discomfort (which food to eat before the procedure), etc. So, the person’s quality of life, their well-being in the short term is taken seriously into account.
