I have been consuming probiotics (greek yogurt) per doctor's orders since my 2011 resection. Zero inflammation since.
I have a book on Crohns written by a doctor that states that there is a suspicion that the public water treatment starting about 100 years ago has removed the "friendly" bacteria from our digestive system and does show correlation to the rise of Crohns cases. I do not have public water where I live and I drink spring water whenever possible. Bottled water is not always spring water, if you read the label its source could from a municipal water plant not a spring.
