OMG! :O I thought I was the only person that drank a gallon or more of water a day!? Actually I've slowed down to about 3 quarts, but still! I don't think you're sweating too much, not with as much water as you're drinking.
It is important to drink lots of water when you are at risk for gout. However, I should think that 1 gallon a day is sufficient. Did you tell your doctor how much you drank? There are other ways to reduce your uric acid other than water. You can also limit your intake of purine rich foods like liver, alcohol, mushrooms, cauliflower, asparagus, beans or peas, etc. Another way is to increase your intake of foods that are natural anti-inflammatories or foods that reduce purine. There aren't many of these that I know of. Tofu/soybean, high omega-3 foods like salmon and some nuts/grains are about all I know of. Perhaps an omega-3 supplement would help.
HOWEVER, the diet you are on is most likely the cause of your increase in uric acid. It is designed to make you lose weight VERY fast. A diet rich in 'good' carbs found in fruits, grains, veggies is what maintains a healthy uric acid level. Your diet is opposite of that. Correct me if I'm wrong but I believe you're not allowed to have any carbs whatsoever on that diet. The other alternatives to lower uric acid is through medication which your doctor should prescribe if your situation worsens. Ask him about them because honestly 3 gallons of water a day is insane and I question whether your body or your bladder for that matter can handle it. Lol, but if you did I imagine it would stretch your bladder and eventually you could drink a gallon of h2o and go on a 16 hour trip w/o peeing! lol
Don't take any of my suggestions or believe anything I say without first consulting your physician and doing your own research. I'm not a physician nor do I work in the medical industry I just happen to know a little bit about this from my father and my old boss. Do a search on the web for Gout Diet or Hyperuricemia Diet and you may find some more answers. Also, KS-Julie may know more about this than I do and can probably provide some more insight.
