I know something that can help you. My bro had kidney stone symptoms and he found a product that actually dissolves them. He used it and it worked.I highly recommend it, it is called "Stone Free" you can go to this website to read about it. http://www.planetaryherbals.com/products/GP1550/ made by -planetary herbals-
People have had the stones dissolve completely while using "Stone Free"
you can find it at several stores online by searching for it in a search engine.
As far as losing weight I think noni juice, they even sell this at walmart now, and organic yogurt for the probiotics would help you. walking even 15 minutes a day. If its is cold where you live even a walk around the shopping mall early in the morning before all the stores open this is a greatt way to get exercise.
