A high urine protein generally means there is some kind of kidney disease going on. With your combination of diabetes and high blood pressure, I believe you should see a kidney specialist immediately, if you are not already. The "foaminess" of the urine is due to the protein. The top 2 diseases that cause kidney damage and/or kidney failure are #1 Diabetes and #2 High Blood Pressure. Well, you gotta double whammy there. Please, seek treatment now to preserve your kidney function.
My cousin has been diabetic since the age of 18 months, she is now 37. She has severe diabetic kidney nephropathy (about to lose what little kidney function she has) and severe diabetic nerve degeneration in her feet. She cannot feel her feet at all. She nearly bleed to death last month while shaving her legs. She nicked the artery in her foot and didn't even notice she was spurting blood everywhere for a good 6-7 seconds until she saw blood splatter on the shower wall.
She has also been in so many diabetic comas, I've lost count. Her specialists can never get her insulin levels right. The lowest I've seen in her has been 20 (which usually means certain death) and the highest has been 1200. During that episode, she "died" 3 times. They shocked her heart 3 times and worked on her for over 40 minutes. Well, they were going to call it quits when her hubby begged them to just shock her one more time. Well, it worked!! She came back with no brain damage. By that time, they had been working on her for almost an hour.
I wish you all the best! I've been through the ringer with my own kidney issues, although not diabetic related. I'm also 37, the same age as my cousin. Both of our Mothers were pregnant at the same time with us and lived together. We often wondered if there was something in the water. I'm such a "rare" case with kidney stones, and she is the "rare" case with her diabetes. Bye for now.
