H.C.
I had similar problems during all three of my pregnancies. High blood was to blame. High blood pressure will also cause kidney problems. What I did not know during my pregnancies is that I have lupus. Look to see if you have any rashes on your face chest or arms. Don't let them tell you it's the mask of pregnancy. It could be much more. It took over ten years to get a diagnosis of lupus. My best advice to you is to keep track of you ph levels in your urine. You can buy test strips at health food stores or order online. My guess is that it will show your body is acidic. To remain healthy you must change that to alkaline. This can be done by eating an alkaline diet. Here's a website that breaks done which foods are alkaline http://www.angelfire.com/az/sthurston/acid_alkaline_foods.... Also, it wouldn't hurt to drink a teaspoon of baking soda in a glass of water one a day. I believe this will make a difference. I wish I had known these things ten years ago! Remember an alkaline diet
consists of mostly fruits and vegetables. Good Luck!
