<<Disclaimer: Verify this information before applying it to your situation.>> Thank you to each and everyone of you who responded. I was shocked at the number of responses I received within 24 hours of posting. It seems that there are many people who experience microscopic hematuria frequently. A number of people experience this after ingesting gluten unintentionally. One person stated that marathon runners frequently experience hematuria after a race (definitely not me - LOL!). I did receive a number of responses stating that hematuria is a symptom of bladder cancer, chronic kidney failure, and IgA Nephropathy. Other members responded saying they have been dealing with hematuria for years, have seen a Urologist/Nephrologist, have undergone multiple tests (including cystoscopy, IVP, CT scans, etc), but still have yet t o receive a definitive diagnosis. One person did state that a swollen kidney was discovered, and another had a fatty tumor on their kidney. The general consensus is that I need to see a Urologist or possibly a Nephrologist, and I completely agree - particularly given the fact that I am not dealing with microscopic hematuria. Thank you again to all of you for your help and support. Barbara * All posts for product information must include the applicable country *
