Dark-colored urine can reflect a variety of conditions affecting various parts of the body, or it can indicate a problem in the urinary system itself. Ordinary deep yellow urine might just be a sign of dehydration, but dark yellow and quite a few other colors can indicate serious conditions a doctor should investigate. Possible issues range from kidney and bladder infection to cancer, and even kidney failure. Dark urine can also be a side effect of some medications, bacterial infections, and improper catheterization. Dark, blood-colored urine, in particular, can be a sign of many problems and should receive prompt attention, diagnosis, and treatment.
Hematuria, the presence of blood in the urine, has many origins and should be investigated promptly. It could be as simple as a poorly placed Foley catheter, or the result of urinary tract infections (UTIs), other infections, cancer, benign prostate hyperplasia (BPH), and physical trauma to the kidneys. When seeing a medical practitioner, try to give as much information as possible about any injuries, how long the urine has been this color, whether the problem has been recurring, and whether you have been having difficulty urinating.
