Why does a man's urine foam?

Normal fresh urine is a transparent, brown liquid, and the color varies depending on the amount of urine. For most people, foamy urine is a very normal phenomenon. This is because the urine contains some organic and inorganic substances, which make the urine very strong and produce some foam. Therefore, foamy urine does not necessarily indicate health problems. But what is the reason for foamy urine in men? Let's learn about it together.

1. Prostatitis

Prostatitis refers to acute inflammation caused by specific and non-specific infection of the male prostate, which in turn causes systemic or local symptoms. The phenomenon of excessive foam in urine is not necessarily caused by prostatitis. If a man suffers from prostatitis, there may be semen in the urine, and there will be oil droplets on the surface of the urine, which will cause increased foam in the urine.

In addition to foamy urine, prostatitis also has the following common symptoms: urinary urgency and pain, burning sensation during urination, dribbling urination, sometimes difficulty urinating, thin or interrupted urine flow

2. Urinary tract infections, such as urethritis, can also cause foamy urine

When you suffer from urethritis, the urethra is infected with gas-producing bacteria, such as Escherichia coli and Aerobacterium, which can produce gas. When this gas-producing bacteria causes an infection in the urogenital system, it can ferment substances such as glucose in the urine to cause foamy urine.

Urethritis also has the following common symptoms: frequent urination, urgency, inability to hold urine, painful urination, discomfort during urination, etc. Patients with acute symptomatic inflammation usually have significant urinary tract irritation signs, but in patients with chronic urinary tract infection, urethral irritation symptoms are generally mild, such as mild frequent urination, urgency, inability to hold urine, or discomfort during urination.

3. Bladder diseases, such as cystitis

When men suffer from cystitis, foamy urine is caused by changes in the composition of their urine.

4. Sexual intercourse for too long

Couples who are separated for a long time and have not had sexual intercourse for too long; habitually agitated people will have foam in their urine due to increased mucus metabolism in the bulbourethral glands and increased interfacial tension in the urine.

5. Urination too quickly will also increase the foam

When you can't hold your urine, the urination pressure increases, the urine flow rate becomes faster, and the interfacial tension in the urine increases, which can also increase the bubbles.

6. There is semen in the urethra

If there is semen in the urethra of men, foamy urine may occur, such as retrograde ejaculation (common in patients with diabetes and autonomic nervous system dysfunction); habitual excitement increases the secretion of the bulbourethral gland, and frequent ejaculation.
