Men with foam in their urine usually have both physiological and pathological factors. Physiological ones are usually seen in concentrated urine, residual prostate fluid in urine after sex and semen, etc. Pathological factors are seen in diabetes, prostatitis, impaired kidney function, urinary tract infections, etc. I. Physiological causes: 1. Urine concentration: If it is the case that occasionally there is foam in the urine, it can be considered the result of urine concentration. Usually, the concentration of urine rises when urine is concentrated, thus making the surface tension of urine greater, which can easily cause the phenomenon of foam in urine; 2, sexual life: when men have sex, the prostate gland and seminal vesicles secrete prostatic fluid, semen has some residue, increasing the surface tension of urine, thus there may be foam during urination, which can usually be relieved by itself. Second, the pathological causes: 1, diabetes: diabetes will make the urine in the urine urine sugar is elevated, the surface tension of the urine becomes larger, easy to have foam produced. You can usually do a fasting blood sugar measurement to clarify whether you have diabetes. If the fasting blood sugar meets the diagnostic criteria for diabetes, it is recommended to control the diet and moderately increase exercise, or you can take oral hypoglycemic drugs or inject insulin for treatment. The urine sugar will be controlled down and the phenomenon of foam in the urine will be significantly improved; 2. Prostatitis: when the male prostate is inflamed, the highly swollen prostate will release more prostate fluid into the urethra, and the prostate fluid itself has a high protein content, so it is easy to produce foam when urinating; 3. Impaired kidney function: due to nephritis, nephrotic syndrome or chronic hypertension, diabetes The damage caused to the kidney function, resulting in a decrease in the role of semi-permeable membrane filtration within the glomerulus, and thus in the glomerular filtration, more protein will seep out of the blood into the urine, forming protein urine, the surface tension of the urine will become larger, easy to form foam. It is recommended to treat the cause at this time, often to achieve a better treatment effect; 4, urinary tract infection: clinically common like urethritis, cystitis, when urinary tract infection occurs, the epithelium of the urethral mucosa is in a highly edematous, congested state, easy to fall off, coupled with the presence of bacteria in the urine, as well as the body’s metabolic waste mixed together, it is easy to produce more foam, usually can be applied Antibiotics are usually applied for treatment.
