    When there are problems with our physical health, there will be many symptoms. Therefore, when there are abnormalities in the body, it is best to go to the hospital for examination, so that timely treatment can be carried out without delaying the condition; for example, when men urinate, foaming urine may be a normal phenomenon, but it may also be caused by some diseases, but when such a phenomenon occurs, men must pay attention to it.

    1. Prostatitis

    Prostatitis refers to acute and chronic inflammation caused by specific and non-specific infections of the prostate, resulting in systemic or local symptoms. The presence of excessive foam in the urine does not rule out that prostatitis is the cause. If a man suffers from prostatitis, his urine may carry prostatic fluid, which will cause oil droplets on the surface of the urine, resulting in increased pee foam.

    In addition to excessive foamy urine, prostatitis also has the following common symptoms: urgent urination, painful urination, burning of the urethra, inexhaustible urination, sometimes difficulty in urination, and thinning or interruption of the urine stream.

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

    When suffering from urethritis, the urinary tract is infected by gas-producing bacteria, such as Escherichia coli and Aerobacillus aerogenes, which can produce gas. When these gas-producing bacteria cause a urinary system infection, they can ferment glucose and other substances in the urine, resulting in foamy urine.

    Urethritis also has the following common symptoms: frequent urination, urgency, painful urination, discomfort during urination, etc. Patients with inflammation in the acute phase often have obvious signs of urinary tract irritation, but in patients with chronic urinary tract infection, the symptoms of urinary tract irritation are usually mild, such as mild frequency of urination, urgency, or discomfort during urination.

    3. Bladder diseases, such as cystitis

    When male friends suffer from cystitis, foaming occurs due to changes in urine composition.

    4. Not having sex for too long

    Couples have been separated for a long time and stopped having sex for a long time; for those who are frequently sexually excited, due to the increase in mucus secreted by the bulbourethral glands, the surface tension of urine increases, and foam will appear in the urine.

    5. Urinating too quickly will also increase foaming

    When urinating urgently, the urinary pressure increases and the urinary velocity increases, which increases the surface tension of the urine and increases the number of bubbles.

    6. There are semen components in the urethra

    In men, the presence of semen components in the urethra can cause foamy urine. Such as retrograde ejaculation (common in patients with diabetes and autonomic nervous system dysfunction); frequent excitement that increases the mucus secreted by the bulbourethral gland, and after nocturnal emissions.

    7. Urine concentration

    In situations such as drinking too little water, excessive sweating, diarrhea, etc., the human body's urine concentration due to insufficient water causes higher concentrations of protein and other components in the urine, which can easily lead to increased foam in the urine.

    8. Suffering from diabetes

    When male friends suffer from diabetes, the content of urine sugar or ketone bodies in the urine increases, the pH of the urine changes, and the surface tension of the urine increases; when there is liver and kidney disease, the content of bilirubin or protein in the urine increases, the surface tension of the urine increases, and more bubbles can be produced during urination; when there are gas-producing bacteria in the urinary tract, bubbles can be produced in the urine.
