What is the reason for a man to suddenly urinate blood?

Many male friends will find that they suddenly urinate blood when urinating. This situation needs to be paid attention to immediately, because it may mean that the patient has prostate hyperplasia, urinary tract infection, urinary tract stones or some systemic diseases. These diseases need to be treated in time. Here are some reasons why men suddenly urinate blood!

1. Hematuria caused by prostatic hyperplasia

Prostatic hyperplasia is the most common disease in elderly men. Hematuria is a common symptom of prostatic hyperplasia. This is because the capillaries in the mucosa on the surface of the prostate become congested, dilated, and twisted after the prostate enlarges. When the bladder contracts or the enlarged prostate is pulled, these capillaries will rupture, causing hematuria.

2. Hematuria caused by urinary tract infection

Renal hematuria refers to hematuria originating from the glomeruli. Clinically, it manifests as simple hematuria or hematuria with proteinuria. It is more common in patients with urinary tract infections. If the treatment is not thorough, the disease recurs repeatedly or is mistreated, the condition cannot be effectively controlled and eventually leads to uremia.

3. Hematuria in men caused by urinary stones

Urinary stones are common diseases of the urinary system, which are usually accompanied by hematuria. The harm of urinary stones to the body ranges from mild to severe. Mild cases only cause some symptoms such as bloating and discomfort in the kidney area or abdomen. The movement of stones usually causes renal colic and hematuria. Severe cases are caused by large and multiple stones or stones that have been in the urinary tract for too long, which blocks the flow of urine, leading to urinary tract infection and ureterorenal hydrops, and kidney function damage.

4. Systemic diseases

In layman's terms, it is caused by some problems in our body. The most common is if there is a problem with our blood system, such as hemophilia or some liver diseases, which will lead to hematuria. Another possible situation is that we take some bad medicines for a long time, such as taking some drugs related to anti-cancer drugs frequently, which will cause problems in our body and may lead to hematuria.
