Dark-colored urine can reflect problems with a wide range of body systems. Urine that is a bit deeper yellow than usual often simply signifies mild dehydration, but notably dark yellow and other colors could be early signs of something more serious, such as kidney infections. Dark urine can also be a side effect of medication or improper catheterization. Urine that looks bloody is particularly worrisome and should prompt a visit to a doctor.
Hematuria, the presence of blood in the urine, has many origins and should be investigated promptly. It could be a urinary tract infection (UTIs) or another infection. Less commonly, it can signify cancer, benign prostate hyperplasia (BPH), and physical trauma to the kidneys. If there is no known reason for blood in the urine (such as menstruation), seeing a doctor is advisable. Offer the medical practitioner as much information as possible about any injuries, how long the urine has been this color, and any other symptoms.
