Blood in urine (hematuria) is not a disease, but an important sign that may be caused by many different diseases. Blood in the urine is often described as a pink or red color, but it can also appear brown or black.
The most common causes of blood in urine are:
Urinary tract infection (UTI)
Trauma to the urinary tract or genitals
Infections of the prostate gland or bladder
Gonorrhea and other sexually transmitted infections (STIs)
Blood in urine is not a normal occurrence and may be a sign of an underlying health condition. It is important to see your doctor if you have blood in your urine so that he or she can determine the cause of the problem.
What Causes Blood in Urine?
Blood in urine results from bleeding in the kidneys or bladder. The most common causes of blood in urine include:
Urinary tract infection (UTI). This is one of the most common causes of blood in urine. UTIs are caused by bacteria entering the urethra and infecting the bladder, ureters, or kidneys. Symptoms include pain during urination, frequent urination, cloudy-colored urine, and lower back pain. Bacteria can be transmitted through sexual intercourse or contact with contaminated surfaces such as toilets or bathtubs.
Kidney stones. These stones form when salts and minerals combine into crystals that cannot pass through your kidneys’ tubes. They usually form in the kidneys but can also develop in the bladder or ureter. Painless passing of small kidney stones is possible; however, larger ones may cause intense pain and require medical attention if they block urine flow through your urinary tract channel and cause infection (pyelonephritis). Other symptoms include nausea
A common cause of blood in urine is a urinary tract infection, which you can treat with antibiotics. Depending on the severity of the symptoms, you may also need to take pain relievers or see your doctor if the pain doesn’t go away after a few days.
Blood in your urine can be dangerous and may indicate a serious medical condition. Call your doctor if you have any of these symptoms:
A bloody discharge for more than two days
Painful urination (dysuria) that lasts longer than 12 hours
Fever above 101 degrees Fahrenheit (38 degrees Celsius)
Cloudy urine or urine that looks like coffee grounds
Blood in the urine (hematuria) can be a sign of kidney, bladder or prostate problems. It can also be caused by injury, such as a cut inside the urethra (the tube that carries urine from the bladder).
Sometimes there’s no cause for concern — it may just be a sign of irritation or inflammation. But if you have blood in your urine and it lasts more than two days, you should see your doctor.
If you’re not sure whether you need to see a doctor, ask yourself these questions:
Is blood in my urine new? If so, go to your doctor immediately or go to an emergency room. You may need immediate treatment to prevent serious complications such as kidney failure or infection.
Does blood come from the tip of my penis when I urinate? If so, see your doctor immediately because this could be a sign of cancer.
Is there blood in my stool? See your doctor if you have bloody diarrhea; it could indicate that you have a serious bacterial infection in your digestive system that needs treatment right away.
Can emotional stress cause blood in urine?
Emotional stress can cause blood in urine. This is called stress urinary incontinence (SUI). SUI is a type of urinary incontinence. Urine is the liquid waste that your body makes. It leaves your body through the urethra, which is the tube that takes urine out of your body.
Emotional stress can make it harder to control when you urinate, so you might accidentally pass urine when you don’t want to or it might leak out on its own. Stress incontinence can affect men and women, although it’s more common in women after menopause.
Emotional stress can include:
Stressful events such as having a baby, moving house, or going through a divorce
Anxiety and depression
Pregnancy-related conditions such as gestational diabetes, preeclampsia (high blood pressure during pregnancy), or preterm birth
Is it possible to have blood in your urine due to emotional stress?
Yes, it is. The most common cause of blood in urine is due to a urinary tract infection (UTI). When you have a UTI, the bacteria infect your urinary tract and cause damage. This can lead to bleeding from the bladder or kidneys into the urine.
Blood in the urine can also be caused by kidney stones or an enlarged prostate gland. These conditions may also cause pain or burning during urination, as well as a feeling that you need to urinate frequently.
If you are having any of these symptoms, see your doctor for an evaluation.
There are many causes of blood in urine, including infection, kidney stones and cancer. Stress can cause blood in urine as well. The condition is called stress urinary incontinence, or SUI.
Stress urinary incontinence is defined by the involuntary loss of urine associated with physical exertion or activity that increases abdominal pressure. It may occur at any age and be associated with pregnancy, childbirth or obesity. Additionally, the condition may be caused by neurologic damage due to trauma to the spinal cord or brain stem.
Stress Urinary Incontinence: Causes & Symptoms
The main cause of stress urinary incontinence (SUI) is weak pelvic floor muscles which support the bladder and keep it from leaking when you sneeze or cough. Other causes include:
Age – As you get older, your pelvic floor muscles become weaker because they aren’t used as much as they used to be during childbirth and other activities requiring physical exertion such as running or lifting heavy objects
Stress is a common cause of blood in the urine. It can be hard to know whether your kidneys are damaged by stress or not, because you can’t see them.
It is important to get to the bottom of the cause of your blood in your urine. This way you can get treatment that can make you feel better and stop you from hurting yourself.
It’s also important to know if there are any other health problems that might be causing it.
If you’re worried about blood in urine, talk with your doctor right away. They can help figure out what’s going on and what you should do next.
What would cause blood in urine but no infection?
Blood in urine can be caused by many things, including infections, kidney stones and trauma to the urethra. However, it is not always easy to make a diagnosis based on symptoms alone.
If you are experiencing blood in your urine, it is important to see a doctor as soon as possible. The doctor will likely perform some tests to determine the cause of the bleeding. This can help them determine the best course of treatment for you.
Blood in Urine: Causes
There are several different causes of blood in urine. Some common causes include:
Urinary tract infection (UTI): UTIs are one of the most common reasons why people come into contact with a doctor because they suffer from blood in their urine. Most UTIs are caused by bacteria entering your urinary tract through your urethra or vagina. If left untreated, UTIs can cause serious complications such as kidney damage or sepsis (overwhelming infection).
Blood in urine can be caused by a number of different conditions. It’s important to have your doctor evaluate the cause so that the appropriate treatment can be provided. Blood in the urine can come from the urinary tract or kidneys, but it can also be caused by conditions outside of the urinary tract, such as infections or bleeding disorders.
The most common causes of blood in urine include:
Infections: Urinary tract infections (UTIs) are by far the most common cause of blood in urine, but there are many other types of infections that can lead to bleeding from the urethra (where urine exits from the bladder). Bacterial UTIs are usually caused by bacteria that enter through the urethra into the bladder. Other types of infections may spread up from below and cause bleeding into your bladder.
Infections like gonorrhea and chlamydia can also spread to your kidneys and cause hematuria (blood in urine). These infections can affect people of all ages, regardless of gender or sexual orientation. If you have these sexually transmitted diseases, it’s important to get tested and treated as soon as possible because they can lead to serious problems if left untreated.
The most common cause of blood in the urine is a urinary tract infection (UTI). This is not to say that other causes do not exist; however, UTIs are the most common cause of blood in the urine.
A UTI occurs when bacteria enter the urethra and travel to the bladder and kidneys. The bacteria cause an infection by releasing toxins into your system. These toxins irritate and inflame your urinary tract, causing pain, burning or discomfort when you urinate and sometimes fever and chills.
There are many reasons for blood in urine. The most common cause is urinary tract infection (UTI). Other causes include:
Injury to the urethra or bladder from sexual intercourse, a medical procedure, or an accident
Leakage of blood or blood clot from somewhere else in the body into the urine
Problems with the kidneys that can cause bleeding into the urine (hematuria)
Injury to the kidneys or urinary tract from an accident or fall
Medications such as nonsteroidal anti-inflammatory drugs (NSAIDs), which can irritate the lining of your urinary tract and increase bleeding
Is hematuria an emergency?
Hematuria is the presence of blood in the urine. It can occur because of trauma to the urinary tract, as a result of infection or kidney stones, or as a side effect of certain medications.
In most cases, hematuria will be noticed by the patient, who may pass blood clots or have a pink or red color to their urine. If you have any symptoms of hematuria, especially if they last longer than one day, it’s important to see your doctor.
Is Hematuria an Emergency?
Hematuria isn’t always an emergency, but it can be. Depending on your situation and what caused your hematuria, treatment may not be urgent. In some cases, however, symptoms such as severe pain or bleeding that cannot be stopped require immediate medical attention — especially if there’s blood in your urine after sex or when you sneeze or cough.
If you’re experiencing these types of symptoms and suspect you might have hematuria, call 911 immediately and tell them about your condition so they can help direct you to the nearest hospital with emergency services.
Hematuria is the presence of blood in the urine. It may be a sign of a serious condition, such as kidney stones or cancer.
The amount of blood, or volume, determines whether hematuria is an emergency.
Signs and symptoms of hematuria include blood in the urine and pain or burning when urinating. Other symptoms may depend on the cause.
Hematuria is often diagnosed with a urine test called a urinalysis. If there’s enough blood to see with your eyes, you don’t need any tests to diagnose it.
Hematuria is the presence of blood in the urine.
Hematuria can be a sign of various conditions, including urinary tract infections, kidney stones, prostate cancer, and bladder cancer. The severity of hematuria varies greatly and depends on the amount of blood found in the urine, the number of drops of blood per milliliter (dL) of urine, and whether or not the person has other symptoms.
In general, hematuria is not an emergency but should be evaluated by a doctor to determine its cause and appropriate treatment.
Hematuria is the presence of blood in the urine. It’s a common symptom, and most people who have it don’t need to see their doctor.
The amount of blood in your urine can vary from trace amounts to enough to cause noticeable discoloration and even clots. If you have hematuria, it’s important to see your doctor right away so he or she can determine the cause, which may be serious or benign.
Some causes of hematuria include:
Infection — Urinary tract infections (UTIs) are by far the most common cause of hematuria; they account for about 35% to 40% of all cases. Infections that affect the upper urinary tract (bladder and kidneys) may cause blood in the urine at any age, but people older than 65 years are more likely than younger people to develop UTIs as a result of changes in their immune systems or urinary tracts.
Kidney stones — Kidney stones are small mineral deposits that form in the kidneys or bladder. They usually aren’t painful unless they travel down into one of your kidneys and block its flow of urine. In rare cases, stones can get stuck in one spot and cause bleeding into your urine (hemorrhagic cyst
Is hematuria an infection?
Hematuria is an abnormal presence of blood in the urine. It can cause a red or pink color to the urine, which makes it easy to detect. Hematuria can be caused by various underlying conditions, such as infections or urinary tract stones. However, it is important to note that hematuria is not always due to an infection.
Infections are one of the most common causes of hematuria. They may include bacterial infections, viral infections and parasitic infections. Some examples of infectious diseases that may cause hematuria include:
Bacterial UTIs (Urinary Tract Infection)
Prostatitis (Inflamed Prostate)
Hematuria is often a sign of infection, but it can also be caused by other conditions.
What is hematuria?
Hematuria is the presence of blood in the urine. It can be due to either an abnormal amount of red blood cells or red blood cell fragments in the urine or to bleeding from within the kidney.
What causes hematuria?
The most common cause of hematuria is urinary tract infection (UTI), which accounts for about 80 percent of cases. Hematuria can also be caused by bladder cancer and diseases that affect the kidneys themselves, such as polycystic kidney disease or glomerulonephritis. Hematuria that results from kidney disease usually occurs along with pain and swelling in one or both sides of your back.
Hematuria is defined as the presence of blood in the urine. This can be caused by many things, including infections and injuries. There are a few different types of hematuria that are commonly seen in veterinary patients:
Microscopic hematuria is the presence of red blood cells in urine that cannot be seen by the naked eye. Microscopic hematuria is most commonly associated with urinary tract infections (UTIs).
Macroscopic hematuria is visible to the naked eye and can be caused by trauma, inflammation or cancerous growths in the urinary tract.
Hematuria means that there is blood in your urine. It’s a common sign of a urinary tract infection (UTI) and can be caused by infections anywhere in the urinary tract — from the urethra to the kidneys.
In most cases, hematuria isn’t serious and clears up on its own within a few days. But if you have blood in your urine, it’s important to see your doctor right away. Hematuria can be an early sign of kidney disease or bladder cancer, so it’s important to find out what caused it.
How do you treat hematuria at home?
Hematuria is the presence of blood in the urine. Hematuria can be caused by many different conditions, including infections and kidney disease. Treatment depends on the cause of the hematuria.
Hematuria is often associated with urinary tract infections (UTIs), but it is not always present when someone has a UTI. A urinary tract infection can cause bleeding because it irritates the lining of the bladder, urethra and kidneys, causing tiny tears that result in bleeding. The bleeding may be visible as red or pink streaks or flecks in the urine or as microscopic red blood cells on a urinalysis report.
In some cases, hematuria may be caused by an injury to your kidneys or bladder from an accident or sports injury. In rare cases, hematuria may be caused by cancerous growths within these organs.
Hematuria is a common condition that causes blood in the urine. It’s usually harmless, but it can be a sign of a serious problem.
If you have hematuria, it’s important to see your doctor right away. He or she will give you a complete medical history, perform a physical exam and take lab tests. In many cases, the cause is obvious. For example, trauma to the urethra or bladder may cause bleeding. Infections and problems such as polycystic kidney disease or cancer may also lead to hematuria.
The doctor will want to know when you first noticed the blood in your urine, how long it’s been there and how much there is. You’ll also need to tell him or her about any other symptoms you’ve been having — such as pain when urinating — so he or she can decide on the best treatment plan for you based on these factors.
Hematuria, or blood in the urine, is a common condition that can be caused by several different factors. The most common cause of hematuria is an infection or inflammation of the urinary tract. Other possible causes include kidney stones, trauma and certain diseases of the blood, such as sickle cell anemia.
If you have hematuria with no other symptoms, you probably don’t need to see your doctor. You may have a minor bladder infection or irritation from a recent sexual encounter. Most often, hematuria will go away on its own within a few days.
In some cases, however, hematuria can be a sign of something serious. If you have severe pain in your kidney area or if your urine turns red continuously for more than six weeks, call your doctor immediately to schedule an appointment.
Hematuria is defined as the presence of red blood cells in the urine. It can be caused by a variety of conditions and may be associated with abdominal pain and other symptoms.
Symptoms of hematuria include:
Bright red or pink urine (fresh blood)
Cloudy or dark urine (old blood)
Blood in the toilet after you pee (gross, but true)
Can dehydration cause hematuria?
Dehydration can cause hematuria, or blood in your urine. This can be a sign of an underlying medical condition, but it can also be caused by not drinking enough water or other liquids.
Dehydration occurs when you don’t have enough water or other fluids in your body. It may be caused by not drinking enough fluid or exercising strenuously in hot weather without replacing fluids lost through sweating.
You might have noticed that your urine becomes darker and more concentrated when you’re dehydrated. This is because the concentration of waste products in your body increases when you become dehydrated, and these waste products will show up as dark yellowish-brown urine instead of clear urine.
If you have any questions about whether or not dehydration is causing your hematuria, see your doctor for advice
Dehydration can cause hematuria, and it is a common cause of kidney stones. Hematuria is the presence of blood in the urine. The most common cause of hematuria is urinary tract infection (UTI), and other causes include trauma to the urethra, kidney stones, cancer and some medications.
Dehydration can cause hematuria because your kidneys don’t filter out all of the waste products in your body. When you are dehydrated, there is less fluid available to help with this process. As a result, your kidneys may not be able to filter out enough of these waste products to keep them from building up in your blood. This can lead to an increase in pressure within the blood vessels located in your kidneys and bladder. If the pressure becomes too high, blood vessels may rupture causing bleeding into your urine (hematuria). The amount of blood that enters your urine depends on how much fluid you drink after becoming dehydrated.
Dehydration is a condition in which your body doesn’t have enough water. It can be caused by not drinking enough fluids, sweating too much, or vomiting or diarrhea.
You can become dehydrated if you don’t drink enough fluids for several days or more. The body loses water when:
You don’t drink any liquids for long periods of time
You sweat heavily without replacing lost fluids
You vomit or have diarrhea, especially if the liquid is green, bloody, or contains bile (a liquid made in the liver that helps digest food)
Dehydration is a very common condition, especially in children and the elderly. It can be caused by many different things, such as lack of water intake, vomiting or diarrhea.
Dehydration is when there is not enough water in the body for the cells to function properly. Dehydration can lead to weakness, dizziness and headaches. In severe cases it can cause convulsions and even death.
Dehydration occurs when you lose more fluid from your body than you take in. You may lose fluids through sweating, urinating or diarrhea. This can happen if you have a fever or are vomiting or having diarrhea.
What does a urologist do when you have blood in your urine?
A urologist is a doctor who specializes in the urinary tract and genital organs. A urologist treats a variety of conditions, including bladder problems, kidney stones, prostate cancer, erectile dysfunction and infertility. A urologist may also perform surgery to remove the prostate or repair an obstruction in the urinary tract.
A urologist will first take a detailed medical history and perform a physical examination to determine if you have any problems with your kidneys, bladder or reproductive system. The doctor may request certain tests, such as blood tests or urinalysis, to rule out other causes for your symptoms. If the doctor suspects that you have an infection or other problem with your urinary system, he may order additional tests such as CT scans or ultrasounds.
If you have blood in your urine, your urologist will likely perform a cystoscopy to examine your bladder using a small tube with a camera on the end known as a cystoscope. During this procedure, he will insert the scope through your urethra into your bladder so that he can check for signs of disease including tumors or inflammation.
Blood in urine is a common symptom, but it can be very alarming. If you’re experiencing blood in your urine, don’t panic. It’s important to see a doctor right away so that the cause of the bleeding can be identified and treated.
Blood in the urine can be caused by a number of different conditions, ranging from benign to serious or even life-threatening. Some types of infections, cancers and kidney stones can cause blood in the urine — as well as some medications.
In some cases, the cause may not be clear-cut. This can make it more difficult for your doctor to diagnose how much blood is in your urine and what’s causing it.
The good news is that most causes are treatable. Most people who have blood in their urine don’t need surgery or other invasive procedures to treat their condition.
If you have blood in your urine, you may have a condition called hematuria. This is not as serious as it sounds, but it can be a cause for concern because it could indicate a serious underlying condition.
Blood in Your Urine: What You Should Know
Hematuria is the presence of red blood cells (RBCs) or hemoglobin in the urine.
It’s normal to have some RBCs in your urine because they pass through the urinary tract when you urinate. But if there are too many RBCs in your urine, it’s considered hematuria.
When to See a Doctor About Blood in Your Urine
You should see your doctor if you notice any of these signs or symptoms:
Most people have heard of UTI (urinary tract infection), but they don’t know what it is or how to prevent it.
UTIs are among the most common infections in women. The urinary tract includes the kidneys, ureters, bladder and urethra. When bacteria get into the urine, they can cause an infection that usually will go away on its own with treatment.
If you have blood in your urine, contact your doctor right away because it may be a sign of a serious problem such as kidney stones or cancer.
If you have symptoms of UTI, see your doctor and ask for a urinalysis (urine test). If you test positive for bacteria in your urine, he or she may prescribe antibiotics to treat your infection.
What vitamins can cause blood in urine?
Vitamins can cause blood in urine. If you have had blood in your urine and you are taking vitamins, it’s important to talk to your doctor.
Vitamin K is a fat-soluble vitamin that’s necessary for blood clotting. It may help prevent hardening of the arteries, but too much vitamin K can cause bleeding disorders. Vitamin K supplements are often recommended for people who are at risk of developing blood clots due to having surgery or taking anticoagulants (blood thinners) such as warfarin (Coumadin).
Vitamin K is also used to prevent and treat osteoporosis (loss of bone density) in postmenopausal women, but this use hasn’t been well studied in men.
If you take vitamin K supplements, be sure to tell your doctor if you have any bleeding problems or symptoms such as nosebleeds or easy bruising.
Iron deficiency anemia is one of the most common types of anemia (lack of red blood cells), especially in women who menstruate monthly because they lose iron through their menstrual flow each month. Iron shortages may also occur during pregnancy and childhood growth spurts when children need extra iron levels for healthy brain development
Vitamin K can cause blood in urine. So can iron supplements. Other vitamins, like niacin, can also cause blood in your urine.
Vitamin K is naturally produced by bacteria in your gut. It helps your blood clot quickly when you’re injured. You also get it from leafy green vegetables like kale and spinach, as well as from other foods that contain vitamin K1 or K2 — including eggs and dairy products. Vitamin K3 comes from food sources such as fish and meat, according to the National Institutes of Health (NIH).
If you take vitamin K supplements for an extended period of time, you may develop a condition called hemochromatosis. This causes too much iron to build up in your body and can lead to cirrhosis of the liver or heart failure. Hemochromatosis also increases your risk for cancer because it creates free radicals that damage DNA in cells throughout your body.
Although hemochromatosis is rare among people who take vitamin K supplements in normal doses, there have been cases reported in which people taking large amounts developed this condition, says Dr. William Abranowicz, director of clinical nutrition services at Cleveland Clinic’s Heart & Vascular Institute (CV
Vitamin B12 deficiency is the most common cause of blood in the urine. Other vitamins that can cause blood in urine include vitamin C, folic acid, vitamin K and pyridoxine.
Vitamin B12 deficiency
Vitamin B12 is essential for the formation of red blood cells, so a deficiency can cause anemia and fatigue. The most common cause of vitamin B12 deficiency is poor absorption from the bowel due to low stomach acid production or damage to the intestinal lining (pernicious anemia). However, it’s also possible for people with normal stomach acid levels and healthy intestines to develop a vitamin B12 deficiency if they don’t eat enough foods containing the nutrient. This can occur in vegetarians who don’t supplement their diets with vitamin B12 or those who follow rigid diets that exclude dairy products, eggs and meat — all good sources of this nutrient.
Vitamin C deficiency
Vitamin C helps protect against cell damage caused by free radicals, which are unstable molecules produced by normal living processes in the body. A deficiency causes scurvy, which includes symptoms such as swollen gums, bleeding under the skin and joint pain. Scurvy is rare today because it can be treated easily with supplements or fresh fruit and vegetables.
It’s not uncommon for people to have tiny amounts of blood in their urine. It may be caused by mild irritation, a urinary tract infection or kidney stones. But if you have more than just a few drops of blood, you should see your doctor.
You may have hematuria if you:
Have pain or burning when urinating
Have blood that’s visible in your urine
Have pain in your lower back, belly or groin area
Have a fever above 100 degrees Fahrenheit (37.8 degrees Celsius)
Age 50 or older
