Causes of blood in the urine

Blood in the urine is a common symptom in many common diseases, due to many different causes. Blood in the urine is not an emergency, but it can be a sign of a serious medical condition. Therefore, when having symptoms of blood in urine, it is necessary to immediately go to a medical facility to find out the cause and take timely intervention measures.

1. Blood in the urine

Blood in the urine is an obvious symptom of a specific medical condition. Normally the urine is light yellow in color and there are no large molecules in the blood. Due to certain abnormalities, possibly from the kidneys or urinary tract, blood cells pass through the glomerulus into the urine.
There are two types of blood in the urine:
Gross hematuria: When blood in the urine is visible to the naked eye. People may detect blood clots or notice red or brown urine. Microscopic hematuria: The presence of molecules in the blood, and only visible under the microscope through laboratory tests.

Blood in the urine Pain in the lower back and sides Nausea or vomiting Occasional fever and chills Cloudy or foul-smelling urine 2.3 Post-exercise hematuria
Post-exercise hematuria is a condition in which blood is present in the urine, occurring after exercise or activity exertion with great intensity.

2.4 Enlargement of the Prostate
The prostate is a small gland about 10-20 grams in size, and only found in men. The prostate gland is located close to the bladder muscle surrounding the urethra, where it connects to the bladder neck, whose main function is to produce fluid that helps the male reproductive process. In addition, the prostate keeps toxins, bacteria, and chemicals out of the urinary tract.
An enlarged prostate can put pressure on the urethra, making it more difficult to urinate. At this point, the bladder can compensate by contracting more to release urine. From there, it can lead to damage and bleeding. Prostate enlargement affects about 50% of adult men between the ages of 51-60 and about 90% of those over the age of 80.
Symptoms of prostate enlargement include:
Urinating many times a day, especially at night, causing insomnia, sudden urge to urinate, not being able to hold urine for more than a few minutes. Difficulty urinating, interrupting, having to push to urinate, weak urine stream, after urinating, there are still a few drops of urine leaking out to wet pants. After urinating, it still feels uncomfortable to urinate. The interval between two consecutive urinations is shortened. Urinary retention: Sudden inability to urinate despite pushing hard, causing discomfort in the lower abdomen, requiring immediate hospitalization. Blood in the urine

2.5 Catheterization
Some patients may experience difficulty urinating or abdominal pain due to surgery, trauma, or disease. Therefore, the patient has a urinary catheter placed in the bladder to help circulate urine out. Normally, the tube that carries urine will stay in the bladder for a few days or weeks.
All types of urinary catheters can allow bacteria to enter the urethra, if not sterile will lead to urinary tract infections related to urinary catheters.
2.6 Kidney damage
Platelets are small structures in the kidneys that filter and clean the blood. In people with glomerulonephritis, the damaged kidney is unable to remove waste from the body. If left untreated, glomerulonephritis can lead to kidney failure.
Acute glomerulonephritis comes on suddenly and can cause the following symptoms:
Swelling of the face in the morning Blood in the urine Decreased urine output Difficulty breathing Cough High blood pressure

Chronic glomerulonephritis progresses slowly. In some cases, there are often no typical symptoms in the early years of the disease. Signs and symptoms in later stages include:
Blood in the urine Protein in the urine Swelling of the face or ankles Frequent urination at night Foaming urine 2.7 Medicines
Some of the following medicines can cause blood in urine :
Anticoagulants: These drugs help prevent blood clots, but some can cause blood in the urine side effects such as warfarin and aspirin. Non-steroidal anti-inflammatory drugs, or NSAIDs: Long-term abuse can cause kidney failure and cause blood to appear in the urine. However, nonsteroidal anti-inflammatory drugs or NSAIDs are unlikely to directly cause blood in the urine. Cyclophosphamide and ifosfamide: These are chemotherapy drugs that can cause hemorrhagic cystitis, which manifests as the sudden appearance of blood in the urine, urinary tract irritation, and bladder pain. Senna: Long-term use of this laxative may lead to hematuria.
