There’s a great deal of confusion surrounding the issue of whether your urine pH should be acidic or alkaline, when you have a UTI.
Most people think that it should be more acidic, largely because they hear that cranberry juice is good for a UTI and that’s very, very acidic.
Also, if they put lemon juice in their water and feel better, they think the lemon juice acidified their urine. More on that, in a bit.
If you’ve used cranberry juice, and it seemed to get better, and then it got worse, this is why…(the link is a very worthwhile read)
..cranberry produces hippuric acid in the urine…Putting hippuric acid into the urine initially kills off the bacteria that have thinner acid-susceptible cell-walls, leaving only thicker-skinned acid-resistant individuals to multiply and pass on their resistant genes.
Therefore, you feel better initially, and then the toughest bacteria take over, and you actually get worse, because the surviving bacteria are now more resistant to anything you take, including antibiotics. Fortunately, this isn’t irreversible, so if you’ve experienced this, don’t freak out.
