I don't know if you are already doing this, but 2 things that have massively improved my health are drinking shit tons of water every day and intermittent fasting. Especially if you have kidney issues.
I fill up a Mason jar with water (24 ounces) and drink at least 4 of them per day.... usually more. Intermittent fasting is basically eating only during an 8 hour period, and not eating for 16 hours - every day.
I eat only between 10am and 6pm. This causes your body to go into autophagy during the fasting period. It basically eats all the bad cells and garbage while going into mega healing mode.
These things plus exercise and cutting crap food out have changed my life. My blood was all messed up similar to what you are saying. Now I am down to 214 pounds from 260 and all my levels are normal. Took about 7 months and am still improving.
