For the past few months, I noticed my taste changed, and not for the better, not that it's great anyway, but doable. I blamed everything from treatment, sinus infection, tooth abrasions, to medications, and just didn't enjoy some foods as I did before.

I have chronic kidney disease anyway from chemo, CKD, probably compounded by other issues, but my baseline creatinine level, which measures kidney function, was 2.2, still high, but acceptable to my nephrologist. It recently raised to 7.5, which is acute renal failure, ARF, causing low hemoglobin too all from a kidney stone, also suggested to be caused by chemo. I was wondering why I was just not feeling well for a while, and think this is one answer.

Anyway, my level is now 3.85, doctors are happy it lowered, said I have nine lives lol, but this prodded me to looked more into CKD, as I should, to help understand, save my kidney. This disease involves a list of other conditions it causes, and one is a metallic, and altered sense of taste and loss of appetite.

So besides taste issues caused by chemo and radiation treatment, who figured, bedsides doctors, that chronic kidney disease would cause a metalic and loss of taste, appetite, and when thinking about it, my taste improved when my creatinine level went down. Meaning my kidney improved. Just something else to consider in the future if I start losing taste again.
