I've been having generalized symptoms such as insomnia, generalized pruritus, headaches, high BP despite being on meds (Amodipine); sleep is hard so may be a factor, on the other hand I do cardio daily and monitor my diet, salt intake.Kidney damage at the level where you have itchy skin, rashes, and fatigue usually happens near stage 4 CKD, or End stage renal failure
No antioxidant is fixing that or countering any effects of it. You have to realize the things you are calling toxins like potassium, and albumin serve functions in the body. It's only when they are critically elevated, and aren't excreted that they compromise other functions in the body (ex. hyperkalemia and cardiovascular issues).
The reason dialysis becomes the only viable solution after a certain point is because things like sudden cardiac death become a far greater risk in people.
You can try high dosing astragalus, but really work with a nephrologist and PCP on this issue as well if you have compromised kidney function.
BP has been hovering at about 150-160/95-100 for months now, even on the amlodipine, and previously on the ramipril.
GFR is 71, am 30, I've asked my GP to see a nephrologist, I'm to run urine proteine tests too.
All those symptoms could appear to be kidney-related, but am not sure if the occurence of those can be correlated with GFR levels or not (aka, levels of uremic toxins in blood may not be directly correlated to GFR).
