Do you consume other beverages besides water and how much?
Do you exercise?
Do you take laxatives or stool softners.
How many times a week do you have a bowel movement?
For myself, I have ammonia smelling stools which leads me to believe that I have some sort of intestinal flora imbalance. My kidneys and liver from what I've been told are fine. I have IBS, reflux and I'm lactose intolerant. No matter what I eat or drink, my stools smell of ammonia and subsequently I smell of ammonia. As a matter of fact, I smell of ammonia daily, regardless of having a bowel movement or not.
