Seeing blood in your urine can be frightening, especially when you are unsure whether it is something minor or a sign of a more serious urinary problem. If you notice pink, red, or brown urine, you may naturally wonder, what causes blood in urine? The cause can range from a urinary tract infection or kidney stone to kidney disease, injury, or other conditions that need medical evaluation.
Blood in the urine, or hematuria, may occur with burning urination, frequent urination, abdominal pain, back or side pain, fever, or nausea. Even painless visible blood should not be ignored, as some causes require prompt treatment. If bleeding is heavy, you cannot urinate, or you have severe pain, blood clots, fever, or worsening symptoms, seek urgent care at our Laredo emergency room.
What Does Blood In Urine Mean?
Blood in the urine, medically called hematuria, means red blood cells are present in the urinary system and may come from the kidneys, bladder, ureters, or urethra. It can occur with a urinary tract infection, kidney stones, inflammation, injury, kidney disease, or less commonly, urinary tract cancer.
A PubMed-reviewed study found that 20% to 25% of people with visible blood in the urine evaluated in hematuria clinics were diagnosed with a urological malignancy, highlighting why visible blood should be medically evaluated rather than ignored.
What Causes Blood In A Man’s Urine?
Blood in a man’s urine, known medically as hematuria, can come from different parts of the urinary system and may occur with or without pain or other noticeable symptoms. While some causes are temporary or treatable, unexplained or recurring blood in the urine should be evaluated by a healthcare professional.
Urinary Tract Infections
A urinary tract infection can irritate the lining of the urinary system and cause blood to appear in the urine. In men, infections can affect the bladder, urethra, or prostate and may cause burning during urination, frequent urination, urgency, or lower abdominal discomfort. Bladder infections may also cause cloudy or strong-smelling urine.
Kidney Stones
Kidney stones can cause blood in the urine as they move through and irritate the urinary tract. They commonly cause sharp pain in the back, side, lower abdomen, or groin, which may come in waves. Nausea, vomiting, painful urination, and frequent urination can also occur. Severe pain, fever, repeated vomiting, or difficulty passing urine requires prompt medical evaluation.
Enlarged Prostate
An enlarged prostate, known as benign prostatic hyperplasia (BPH), becomes more common with age and can interfere with normal urine flow. It may cause difficulty starting urination, a weak or interrupted stream, frequent urination, or a feeling that the bladder has not emptied completely. In some cases, an enlarged prostate can contribute to blood in the urine. Severe blockage can result in urinary retention, which requires urgent medical attention.
Prostatitis
Prostatitis is inflammation of the prostate that may be caused by a bacterial infection or other factors. It can cause blood in the urine along with burning during urination, pelvic pain, difficulty urinating, or pain during ejaculation. Acute bacterial prostatitis may also cause fever and chills and can require prompt treatment.
Kidney Disease
Certain kidney diseases can damage the small filtering structures inside the kidneys, allowing red blood cells to leak into the urine. This may cause microscopic blood that is only detected through testing, although some kidney conditions can make urine visibly pink, red, or brown. Other signs can include protein in the urine, swelling, high blood pressure, or changes in kidney function.
Bladder Or Kidney Cancer
Blood in the urine can sometimes be an early sign of cancer affecting the bladder or kidneys. Importantly, urinary bleeding may occur without pain, so the absence of discomfort does not rule out a serious condition. Visible or recurring blood should be evaluated when there is no clear explanation, particularly in people with risk factors such as older age or a history of tobacco exposure.
What Causes Blood In Urine For Women?
Seeing blood in your urine can be unsettling, especially when you are unsure whether it is coming from the urinary tract or another source. Blood in urine for women, medically called hematuria, can occur with or without pain and may sometimes be noticed as pink, red, or brown urine. While some causes are common and treatable, unexplained or recurring blood should be medically evaluated to identify the underlying problem and rule out conditions requiring prompt care.
Urinary Tract Infections
Urinary tract infections are a common cause of blood in the urine and can irritate the bladder or urethra. Women may also experience burning when urinating, frequent urination, urgency, lower abdominal discomfort, or cloudy and strong-smelling urine. Bladder infections can sometimes spread to the kidneys, causing a kidney infection with fever, chills, nausea, or pain in the back or side. Prompt treatment can help prevent complications.
Kidney Stones
Kidney stones can cause bleeding when a stone moves through the urinary tract and irritates its lining. Women may experience sharp pain in the back, side, lower abdomen, or groin, sometimes accompanied by nausea or vomiting. Painful urination and an increased need to urinate can also occur. Severe pain, fever, persistent vomiting, or difficulty passing urine requires prompt medical attention.
Kidney Infections
A kidney infection can develop when bacteria travel from the bladder to one or both kidneys. In addition to blood in the urine, symptoms may include fever, chills, back or side pain, nausea, vomiting, and painful or frequent urination. Kidney infections require timely treatment because an untreated infection can spread into the bloodstream.
Menstrual Or Vaginal Bleeding
Blood noticed when urinating does not always originate from the urinary tract. Menstrual blood or vaginal bleeding can mix with urine and make it appear as though there is blood in the urine. This can make it difficult to determine the source based on appearance alone. If blood continues to appear outside of menstruation or you are unsure where the bleeding is coming from, medical evaluation can help identify the cause.
Kidney Disease
Some kidney diseases can damage the structures responsible for filtering blood, allowing red blood cells to enter the urine. The blood may be microscopic and detected only during a urine test, although some conditions can cause visibly pink, red, or brown urine. Other possible signs include protein in the urine, swelling, high blood pressure, or changes in kidney function.
Bladder Or Kidney Cancer
Blood in the urine can sometimes be associated with cancer affecting the bladder or kidneys. Importantly, urinary bleeding may occur without pain or other obvious symptoms, so painless blood should not automatically be considered minor. The risk generally increases with age and certain risk factors, including tobacco exposure.
When To Go To The ER For Blood In Urine
Blood in the urine does not always mean you need emergency care, but certain situations require immediate evaluation because they may indicate severe infection, urinary blockage, significant bleeding, or an injury to the urinary tract.
- Inability to pass urine despite having a strong urge to urinate.
- Heavy or persistent urinary bleeding that does not stop.
- Large blood clots interfere with urine flow.
- Severe or rapidly worsening pain in the back, side, abdomen, or pelvis.
- High fever with chills and significant urinary symptoms.
- Fainting, severe weakness, confusion, or signs of shock.
- Blood in the urine following a serious accident, fall, or other major trauma.
- Severe vomiting with an inability to keep fluids down.
If seeing blood in your urine is worrying you, it is understandable to want medical care quickly. If you are searching for an ER near me, seek the nearest emergency department when your symptoms are severe or worsening.
Treatment For Blood In Urine
Seeing blood in your urine can be worrying, especially when the cause is unclear. Treatment depends on what is causing the bleeding, so a healthcare professional may use urine tests, blood tests, imaging, or other evaluations to find the source. Some causes are easily treated, while others require specialist care.
- Antibiotics: Bacterial urinary tract or kidney infections may require prescription antibiotics to clear the infection and stop related bleeding.
- Kidney Stone Treatment: Small stones may pass with fluids and pain management, while larger or blocked stones may require a procedure to remove or break them apart.
- Enlarged Prostate Treatment: Medications can improve urine flow and reduce prostate-related symptoms. Severe blockage may require a procedure.
- Prostatitis Treatment: Bacterial prostatitis is usually treated with antibiotics. Severe infections may require hospital treatment and intravenous medication.
- Kidney Disease Treatment: Treatment depends on the specific kidney condition and may include medications, blood pressure control, dietary changes, or specialist care.
- Cancer Treatment: If cancer is responsible, treatment may include surgery, medication, radiation, immunotherapy, or other treatments based on the cancer type and stage.
