How reliable the results of a bowel examination depend primarily on the proper preparation of the bowel for this procedure.

Then after an hour or two you need to take a laxative with an oil base. It can be castor oil up to 50 ml. Dinner - a slab-free diet is needed: avoid raw vegetables and fruits, and cabbage in raw and boiled or stewed form. Instead, you need to drink kefir for dinner, you can eat sour cream, cottage cheese, semolina, chocolate and fruit juices or fresh juices. You can also have baking, but a little. Wholemeal bread is excluded.
