What Causes Elevated Creatinine Levels In Blood?

Question : My last physical revealed a high normal creatine level in my blood. I am reasonably healthy and well nourished, retired, happily married adult W/M, 6'2" tall, 127 lbs. (50" chest/38" waist) I exercise by working in my yard and in FL I often get dehydrated. I do the cooking and I have experienced gout in the past, but changed my diet and eat reasonably healthy; organic, omega 3 oils, and rBST - GMO - glutamate and hypo glycemic starch/veggie free. However, now and then I get off my diet and experience pain, redness and swelling (localized, not edema) in my ankles, knees and wrists. I eat less red meat, no longer drink sugared drinks, drink spicy V8 and eat fresh veggies, but probably not enough. I drink an alkaline, ionized high PH bottled water which I add two eye droppers of 35% food grade H2O2 to every liter. I keep my VD3 levels above 80% and take a multi-vitamin for men with probiotic, a fruit and vegetable blend and antioxidant support. I also supplement with Cucumin/Tumeric and EGCG (Teavigo). I have also have reduced my supplementation to moderate levels and also take a prostate support supplement. Lately, I have experienced pain in my lower back kidney area when I get up in the morning. I sleep well. I still take BP meds, NIFEdipine 60 mg ER XL and Lisinopril-HCTZ 20 - 12.5, but I have my BP down to nearly normal; occasionally below normal. I have a few beers with my wife before dinner. I don't get sick normally, but my next physical isn't scheduled until this fall. I have a new doctor, a flight surgeon (I am a student pilot/42 hours SEL/FW) now because mine, an internist specializing in nephrology was murdered by his wife. This doctor does not understand the benefits of nutrition; supplementation synergies that can be of benefit. I subscribe to the (Russell L.) Blaylock, M.D. Wellness Report, but have not seen anything in his library that is relevant to my situation. If you cannot tell, I was a career private investigator/research analyst/bodyguard the last 45 years and ran my own agency for the last thirty. Respectfully submitted, XXXX
