Hello, Welcome to Health Care Magic. I went through your query and I understand your concern Seeing blood clots in the urine may be frightening, but it is a common problem. Often, when there are many red blood cells in the urine the urine colour turns red, pink, or brownish, and this may considered hematuria, a medical term for blood in the urine. Before discussing the possible causes of hematuria, it is worthwhile to note that the urine may sometimes turn brown for reasons other than bleeding in the urinary tract, like consuming food or drinks containing food colourings. Bleeding in the urinary tract can come from any part of this system, from the kidneys to the ureters, urinary bladder, and the urethra. Real hematuria may be caused by many factors, including urinary tract infection, kidney stones, injury to any part of the urinary tract and/or the genitals, cancer in any part of the urinary tract etc. I recommend you see a local doctor because it may be a sign of a disease or condition that needs immediate treatment. The presence of other symptoms like severe flank or back pain, fever, and other unusual changes must prompt you to seek emergency consultation because you may have a severe urinary tract infection or stone that can affect your genital health. Bloody urine with loss of appetite and unexplained weight loss may be associated with cancer in the urinary tract and needs serious treatment. Hope I answered to your question. I wish you health. Kind Regards, Dr. Ina Zaimi
