Hematuria is the medical term for blood in your urine. Several different conditions and diseases can cause hematuria. These include infections, kidney disease, cancer, and rare blood disorders. The blood may be visible or in such small quantities that it can’t be seen with the naked eye. Any blood in the urine can be the sign of a serious health problem, even if it happens only once.
You should make a doctor’s appointment as soon as possible. Ignoring hematuria can lead to the worsening of very serious conditions like cancer and kidney disease. Your doctor can analyze your urine and order imaging tests to determine the cause of the hematuria. They can then treat that cause.
What Causes Hematuria? There are many possible causes for hematuria. In some cases, the blood may be from a different source. Blood can appear to be in the urine when it’s really coming from the vagina in women, the ejaculate in men, or from a bowel movement in either men or women. If the blood is truly in your urine, there are several potential causes.
Infection. Infection is one of the most common causes of hematuria. The infection could be somewhere in your urinary tract, your bladder, or in your kidneys.
Stones. Another common reason for blood in the urine is the presence of stones in the bladder or kidney. These are crystals that form from the minerals in your urine.
Enlarged Prostate. In men who are middle-aged and older, a fairly common cause of hematuria is an enlarged prostate. This gland is just beneath the bladder and near the urethra.
Kidney Disease. A less common reason for seeing blood in the urine is kidney disease. A diseased or inflamed kidney can cause hematuria.
Cancer. Cancer of the bladder, kidney, or prostate can cause blood in the urine. This is a symptom that often occurs in advanced cancer cases. There may not be earlier signs of a problem.
Medications. Certain medications can cause hematuria. These include:, penicillin, aspirin, blood thinners like heparin and warfarin, cyclophosphamide, which is a drug used to treat certain types of cancer.
