What is the cause of occult blood in urine?

Occult blood in urine usually refers to trace amounts of red blood cells in the urine, which may be a warning sign of health problems. Occult blood does not always mean a serious health problem, but understanding its causes can help us pay better attention to our health.

There are many reasons for occult blood in urine, including urinary tract infection, stones, trauma, etc. Urinary tract infection may be caused by bacteria, which can cause inflammation of the urethra, bladder, and even kidneys, and symptoms such as frequent urination and painful urination. Stones are small lumps formed by mineral crystals in urine, which may scratch the urinary tract and cause bleeding. Trauma may be due to direct damage to the abdomen or urinary system due to exercise, accidents, etc.

Certain systemic diseases may also cause occult blood in urine. For example, glomerulonephritis is a disease that affects the filtering function of the kidneys, which often causes the leakage of red blood cells in the urine. Some blood system diseases, such as hemophilia and thrombocytopenia, may also cause similar symptoms. The use of certain medications may also cause occult blood in urine, such as anticoagulants.

Lifestyle and eating habits may also have an impact on the condition of urine. After strenuous exercise, the body may experience a brief occult blood in the urine, which is caused by the stress of exercise on the body. Certain foods, such as beets and blueberries, may also change the color of urine. Although this is not true occult blood, it can be misleading.

When faced with occult blood in urine, the most important thing is to stay calm and seek medical attention for professional examinations in a timely manner. Doctors usually recommend routine urine tests, B-ultrasound, etc. to determine the specific cause. Early detection and treatment can help prevent potential health problems from worsening. Maintaining good living habits, paying attention to a balanced diet and moderate exercise can also help prevent the occurrence of occult blood in urine.

By understanding the possible causes of occult blood in urine, we can better pay attention to our health and take necessary measures in time to ensure the good condition of our body. I hope this information is helpful to you. Maintaining a healthy lifestyle is always a good choice.
