There are foams in the urine, which means that the kidneys are not good? There may also be several reasons

Netizens asked:

"I am 55 years old. I recently got up to go to the toilet and found foam in my urine. I had a kidney function check a few years ago and it was normal. There was nothing wrong with my urine routine. But my blood sugar is a little high. What is the difference between the two? Contact? What should I do?"

formation of foamy urine

Urine is generally colorless or light yellow. If foam occurs, it is related to the surface tension of the urine liquid. The higher the surface tension of the liquid, the easier it is to form foam. The increase in the surface tension of urine is mostly related to the changes in the composition of the urine, usually due to the increase in protein, mucus, and organic matter. Of course, it may also be related to the impact force when urinating.

Causes of Foamy Urine

There are two kinds of foam in urine, which are physiological and pathological.

Physiological foamy urine

Strong urine tension, excessive urination, high urination position, frequent sexual excitement, nocturnal emission, insufficient drinking water, diarrhea and other reasons lead to insufficient water in the body, and then the phenomenon of concentrated urine, which will cause foam Urine. If the foam disappears after standing for a while, it usually means that it is physiological foamy urine, so there is no need to worry.

pathological foamy urine

① Kidney disease. When there is a problem with the kidneys, it will lead to excessive protein precipitation, and a layer of fine foam will float on the surface of the urine, which will not disappear for a long time, forming proteinuria.

② Diabetes. The patient's urine contains a lot of glucose, which is easily decomposed and utilized by bacteria. Bacteria will grow and multiply in the urine, so there will be bubbles in the urine.

③ Cystitis. Bacteria multiply in the patient's bladder, decompose the organic matter in the urine, and produce gas, which is excreted with the urine, then foamy urine will appear.

④ Colon disease. If there is inflammation in the colon, a tiny fistula will form between the bladder and the rectum, and the gas in the intestinal cavity will enter the bladder through the fistula and form foam when it is discharged with urine.

Therefore, when there is foamy urine for a long time, and frequent backache, eyelid edema, frequent urination, and urgency, it is best to go to the urology department or nephrology department for examination. Generally, urine routine, urine culture, renal function and other tests can basically find out the cause of foamy urine.
