Why is there foam in the urine?

First of all, there is foam in the urine. Many people’s first impression is that it is caused by the impact. However, if the foam does not disappear, it may not be simply due to the impact. There may be an internal problem in the body. When most people think of urine, they think of the kidneys. In fact, sometimes it is not necessarily a kidney problem. Let’s take a look at what are the causes of foamy urine?

1. Caused by urethral examination

When performing cystoscopy, retrograde pyelography, or catheterization due to kidney, bladder, prostate and other diseases, gas may enter the bladder and ureter Even the kidneys, and then blistering will occur when it is excreted in the urine. This type of bubble urine requires no treatment and is generally not harmful.

2. Urinary tract infection

The urinary tract is infected by gas-producing bacteria, such as Escherichia coli, Aerobacillus aerogenes, Proteus mirabilis, Pneumoniae, and Saccharomyces cerevisiae, etc., which can produce gas. When these aerobic bacteria cause a urinary tract infection, they can ferment glucose and other substances in the urine to produce gas.

3. Diabetes

If blood sugar is not well controlled, diabetic patients may also experience foamy urine. This may be due to gas-producing bacteria causing bias in the urine in the tissue. The fermentation of glucose produces carbon dioxide and hydrogen.

4. Concentrated urine

In situations such as drinking too little water, excessive sweating, diarrhea, etc., the human body causes concentrated urine due to insufficient water, and various components in the urine Changes, such as an increase in protein, mucus and organic matter, can increase the surface tension of urine, making it easy for foam to appear in urine.

5. Body fluid urine

Some men have semen components in their urethra, so when they go to the toilet, there may be a certain amount of foam in the urine. This is not something you should be overly concerned about. I am worried that this is foamy urine caused by semen. 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.

6. Urethral injury

Due to trauma, tumors, inflammation, childbirth, congenital malformations, surgery and other factors, the urethra is the same as the gas-containing organs or tissues such as the intestines or female private parts. , that is, the formation of leakage channels, can also cause foaming urine.

7. Under what circumstances will there be bubbles in urine?

1. Eating big fish and meat

"Bubbles in urine" is a common clinical problem. In fact, Having bubbles is not necessarily a bad thing. Sometimes, even if a careful examination confirms that there is "proteinuria", it is not necessarily an illness. It is probably because you ate a lot of high-protein fish and meat the night before, such as steaks and seafood. , barbecue, etc., if the limit of filtration by human kidneys is exceeded, the protein will escape into the urine.

2. Intense exercise

Having done a lot of or intense exercise the day before may also cause "proteinuria". Since human muscles are mainly composed of protein, proteinuria may occur when doing a lot of exercise. In addition, colds or acute inflammation of the body are also causes of increased protein in urine.

In other words, as long as the diet becomes lighter, or you rest for a few days after exercise, check again (a faster way is to directly observe the bubbles in the urine), if the bubbles no longer appear , it should be no problem.

So, having bubbles in your urine does not necessarily mean there is a kidney problem.
