The majority of causes of blood in your urine are not dangerous, but red or white blood cells in your urine might indicate a medical problem that requires treatment, such as kidney illness, urinary tract infection, or liver disease. White blood cells (WBCs) in your urine may also be seen after exercise or sexual activity and usually goes away on its own within 24 hours.
Kidney disease is one cause of blood in the urine. The kidneys filter out waste from the body through urine, so if they aren't working properly, you will start to build up this waste material in your blood and other parts of the body. This waste material can then end up being passed in your urine.
Blood in the urine can also be caused by problems with the lining of the bladder or urinary tract. These problems include injury, inflammation, and cancer. In addition, women often experience blood in the urine after having a baby because the birth process can damage the bladder muscle layers causing leaks into the urine stream. As we age, our ability to empty our bladders decreases which can lead to repeated episodes of blood in the urine.
Finally, blood in the urine can be a sign of an infection. A small amount of blood in the urine does not necessarily mean that you have an infection. However, if the blood is mixed with white cells, it is likely to be due to an infection.
Blood in your urine can indicate a problem with your kidneys or another component of your urinary tract. The medical term for blood in your pee is hematuria. Hematuria is classified into two types: Gross hematuria occurs when there is visible blood in the urine. Microscopic hematuria refers to the presence of red blood cells on the microscope slide but not enough to see from outside the body. Having microscopic amounts of blood in your urine can be a sign of many health problems, including kidney disease, malignancies, and infections.
Gross hematuria can be caused by many different conditions, most often involving the kidneys. These include diseases such as glomerulonephritis (an inflammatory disease that affects the structure of the kidney filtration system) and vasculitis (when blood vessels become inflamed). Other possible causes include trauma to the bladder or upper part of the urethra, radiation therapy to the pelvic area, and certain metabolic disorders such as porphyria (when blood cells are destroyed before they can disintegrate).
Some factors such as fever, infection, or physical activity may cause blood to appear in your urine. So too might medications such as acetylsalicylic acid (aspirin), NSAIDs (non-steroidal anti-inflammatory drugs), or alcohol. These substances can also cause bleeding into the urine stream. Sexual activity can also lead to blood in the urine.
/span > Microscopic hematuria is detectable as red blood cells under the microscope but not by the naked eye.
Gross hematuria can be caused by many different diseases and conditions, including kidney problems (such as cancer), bladder problems (such as cancer), stomach problems (such as ulcers), respiratory problems (such as tuberculosis), and liver problems (such as cirrhosis). Gross hematuria can also be a sign of serious non-kidney-related illnesses such as leukemia or lymphoma. Microscopic hematuria is common among young people but can be associated with many different diseases. It is important to determine the cause of microscopic hematuria because its treatment depends on the cause. For example, if you have microscopic hematuria due to bladder cancer, then you will need to receive further treatment for that condition.
