A new study, published in Digestive Diseases and Sciences, found that when people with constipation took a probiotic before colonoscopy, the scope was able to get a clearer look at the colon walls, so the test results were more meaningful. Participants who took the probiotic also had fewer gastrointestinal symptoms before and after the procedure.
The study included 104 people who had constipation and 107 people who did not. All had been referred for routine colonoscopy. Each group was divided into two subgroups, one to receive a probiotic supplement, and the other, a placebo. Probiotic capsules contained 1 billion CFU (colony-forming units) of Bacillus subtilis and 9 billion CFU of Streptococcus faecium. People in the probiotic subgroups took one capsule three times per day for two weeks before the colonoscopy.
Prep for the colonoscopy was the same for all groups: they were instructed to eat only soft foods on the day before the test, and no food for the final 18 hours before the test. A purging drink was taken the evening before and the morning of the test to clean out the bowel.
“We found that constipation definitely interfered with bowel cleansing because the constipation group had poorer bowel preparation status (bowel cleansing degree), as expected,” the study’s authors explained. “We also found that the disadvantage of constipation could be offset with probiotics pretreatment.”
Here are some tips to help with colonoscopy prep:
