Mine was fecal sometimes it turn to urine smell other times garbage or barf smell, all comes from my breath due to bad digestion, urine smell is (like) the feces of the bad bacteria when it grows a lot in the body, Sugar feed bacteria and make it grow, hydrochloric acid hot peppers also raw pumpkin seeds help killing bacteria and parasites, probiotics put back the good bacteria in the digestive system which will fight and eat the bad bacteria and give good digestion and good immune system, sometimes I stop the probiotices then I take it back when I feel I need it again, also careful with the amount of cayenne pepper because it lower blood pressure.
You will not loose anything to try this and it is not expensive, I use Yakult and activia yogurt also Acidophilus from grocery store as probiotics, it may work for you too, God bless you.
