My friend who is a diabetes type 2 was having problem with kidneys. His doctor advised him to take 500 mg baking soda tablet one in the morning and another in the evening. His kidney is working correctly. But if he stop taking baking soda tablets, his kidney is not functioning properly. Baking soda will keep the body alkaline. You may try this technique.
A daily dose of bicarbonate soda could stop kidney disease and dialysis. I was told that I was at stage 3 in my kidney disease and eventually I would have to go on dialysis. The University Hospital in London had done some trial tests whereby taking a daily dose of bicarbonate soda could prevent the development of the disease. So, I had nothing to lose and took a teaspoon of bicarbonate soda with a glass of water twice a day. My tests came back and there has been no progression of the disease - hopefully it is in check, but the results look good.
On a second note, I have taken coca-cola with asparagus and on the last two occasions my kidney stones have disappeared. So, when it comes to my kidneys - the future is looking a little brignter. Cheers, Ian
