5. Bad smell in urine
Many bacteria digest some of our bodily fluids or substances and the product of their metabolism are chemicals with bad odor. These chemicals are the cause of the smell of sweat, breath, feet, and privates.
When there are bacteria inside our bladder, their own “pee” ends up on our own, and our urine starts smelling bad.
Again, urine does have its characteristic odor, which isn’t the most pleasant of all, but in case of bladder infections the urine smells differently and it is easy to identify that something strange is going on.
