A person who has blood in the urine, or hematuria, should contact his doctor right away to determine the cause, as the kidneys or other parts of the urinary tract are allowing blood to leak into the urine, states Mayo Clinic. While some medications and foods cause urine to turn a red color, blood in the urine looks different and can indicate a serious medical problem that requires treatment.
Potential causes of blood in the urine include a urinary tract infection, a kidney infection, a bladder stone, kidney stones or kidney disease, according to Mayo Clinic. In men, it can signal an enlarged prostate. Some types of cancer, certain inherited disorders, strenuous exercise and kidney injury can also cause blood in the urine.
Many symptoms may occur along with hematuria, including urine that is pink, red, brown or tea colored, explains WebMD. A person who has a bladder infection may also experience pain or burning when urinating, fever, and belly pain. A person who has a kidney infection may have additional symptoms such as fever, chills and pain in the lower back. Kidney stones typically cause severe pain in the pelvis or abdomen, and a person who has a kidney disease may experience symptoms such as high blood pressure, swelling of the body, weakness and puffiness around the eye area.
