With the popularization of medical knowledge, everyone will master some health knowledge, such as kidney disease may be related to foam urine. As a result, once someone found that there was a bubble in the urine, it became very alarmed. In fact, foam urine is not necessarily a kidney disease.

How do bubbles form in urine? Normal urine has low surface tension and few bubbles, so no foam urine will occur. If you eat too much protein food, the urine will easily bubble. But the bubble will soon disappear.

In another case, due to various reasons, when the composition of urine changes, the surface tension of urine increases and the number of bubbles increases. Normal urine contains some organic substances (glucose) and inorganic substances (mineral salts), which can make the surface tension of urine become stronger, and some bubbles can be produced by impact force when urinating. But these bubbles will soon disappear. If it is proteinuria, the bubble will not disappear. Therefore, the emergence of foam urine is not necessarily ill.

Common causes of foaming in urine are:

1. Insufficient drinking water. When urine is concentrated or urgently urinated due to insufficient drinking water, the pressure of urination increases, the speed of urine increases, the surface tension of urine increases, and the bubbles in urine increase.

2. Cystitis or other urinary tract infections. In this case, the composition of urine is prone to change to produce bubbles.

3. Diabetes. With the increase of urine sugar or ketone body content, the acidity and alkalinity of urine changed, and the surface tension increased.

4. Gas-producing bacteria. When gas-producing bacteria exist in the urinary tract, bubbles can be produced in the urine.

5. Before and after sex. As the secretion of semen and prostatic fluid increases, there will also be more bubbles in urine.

6. Liver and kidney diseases. The Urine Bilirubin or protein content of patients with this kind of disease increased, the surface tension of urine increased, and more bubbles were produced during urination. The earliest change in nephritis is the presence of proteins in the urine. At this time, there are often no other symptoms or signs except occult blood in the urine. If the patient has a history of urination, frequent urination, urination, edema, high blood pressure, or polyuria, polyuria, polydipsia, thirst, and other symptoms, the patient must be admitted to the hospital for diagnosis and effective treatment.

In short, there are many reasons for the increase of bubbles in urine, so don't be too alarmed. The best way to distinguish oneself is to take a container into urine and shake it with hands. Generally speaking, if the foam is larger or different in size, the duration is shorter, the body may not be any problem, and there is no need for tension. If there is a small and persistent foam on the surface of the urine, it is suspected of proteinuria.

There is also a point to remind you that albuminuria is also physiological, without fear, such as functional albuminuria. This is mainly due to intense physical labor or exercise, long marches, fever, high temperature work or severe cold, mental tension, congestive heart failure, high protein diet, increased glomerular filtration membrane permeability, often occurs in healthy young people or adults.

In addition, the more bubbles, the more serious the proteinuria. The emergence of foam urine is only a clinical manifestation. Without professional examination, it can not be regarded as a disease symptom. That is to say, there is only the possibility of albuminuria, whether it is albuminuria, or need professional examination. It should be reminded that the occasional detection of urinary protein "+" does not mean that the kidney must be damaged. Urinary examination should be done many times and combined with renal function examination; if necessary, renal biopsy should be done to determine the degree of kidney injury.

There is no connection between foam urine and proteinuria. Some people with serious kidney diseases do not necessarily have many bubbles in their urine. Therefore, there is no scientific basis for judging whether there is kidney disease from single bubble.
