Kidney stones are formed in the kidneys, originally starting as tiny specks of solid substance. As more material clings to the first speck, it gradually builds into a solid object. The substances are made out of phosphates, urates, etc. They are salts of phosphoric acid and uric acid generally combined with calcium and/or magnesium. They are formed in the kidneys because the environment is too acidic.
These salts are acidic salts. Although calcium and magnesium are in the salts, they are there to soften the poisonous effects of uric acid and phosphoric acid.
Some people mistakenly believe that kidney stones are formed because there is too much calcium. That is not true.
The best proof is that the calcium compound will dissolve in acidic urine while kidney stones will not. If you add calcium into the bladder and lower the acidity of the urine, kidney stones will dissolve.
Drinking plenty of alkaline water will prevent the kidney stones from forming to begin with, and even after the formation, it can dissolve them. Because urine is acidic and so are most of the other waste products, any extra calcium your body doesn’t need will be dissolved and discarded in the urine. In the process, it will help dissolve kidney stones, if any. There is no need to worry about too much calcium consumption.
Kidney Disease As the body produces more acidic wastes, the kidneys get more taxed because they have to remove those acids from the blood. Nephritis, uremic poisoning, bladder diseases, etc. are all acid- related conditions which can be improved by the consumption of alkaline water. It also helps control osmotic pressure in the kidneys
