The difference between foamy urine and proteinuria, teach you a few tricks to distinguish the difference

Many people don’t know much about foamy urine and proteinuria. You should know that foamy urine is not proteinuria. If the bubbles persist for a long time, you should be alert to proteinuria. The most common cause of proteinuria is nephritis, which should be checked in time.

1. Generally speaking, if the foam is large or of varying sizes and lasts for a short time, it is because some organic substances (glucose) and inorganic substances (mineral salts) in the urine make the urine tension stronger, which is normal foam. This foamy urine does not necessarily mean that there is something wrong with your body, so there is no need to worry. However, if the bubbles are large and disappear quickly, you should be alert to whether it is diabetes.

2. If there is a layer of fine foam floating on the surface of the urine and it does not dissipate for a long time, it is likely proteinuria. The best way to identify it yourself is to take a test tube filled with 20 ml of urine and shake it back and forth with your hand. If small bubbles that do not dissipate for a long time appear on the surface of the urine, it is suspected proteinuria. Urine testing should be the basis for diagnosis. You should go to the hospital in time for further examination and diagnosis. The earliest change of nephritis is the appearance of protein in the urine. During this stage, there are often no other symptoms or signs except occult blood in the urine. If the patient has foamy urine accompanied by frequent urination, urgency, pain when urinating, or edema, high blood pressure, or symptoms such as polydipsia, polyuria, polyphagia, and dry mouth, he must go to the hospital for examination and diagnosis and take effective treatment measures.

3. We know that normal fresh urine is a transparent, amber liquid , and the color can be dark or light depending on the amount of urine. But why does foam appear in urine?

Under normal circumstances, the surface tension of urine is very low and fewer bubbles are formed. Urine contains some organic and inorganic substances, which make the urine tension stronger and cause some foam to appear. Therefore, the appearance of foamy urine does not necessarily mean that there is an illness. But because

For various reasons, when the composition of urine changes, the surface tension of urine increases and the number of bubbles increases.

Normal urine does not have too much foam. When the urine contains a large amount of protein, the surface tension of the urine increases. At this time, a layer of fine foam will easily form on the surface of the urine, and these small bubbles are not easy to disappear. Therefore, when a large amount of foam forms on the surface of urine, a urine test must be performed to detect pathological conditions such as proteinuria in a timely manner. When the protein content in 24-hour urine exceeds the normal range, it is called proteinuria. Proteinuria may occur in the following situations:

Proteinuria is not always pathological. It can be divided into functional proteinuria and pathological proteinuria. Functional proteinuria, also known as physiological protein, refers to temporary proteinuria that occurs in healthy people. It is more common in young people and occurs during strenuous exercise,

Under the influence of factors such as heat, high temperature, cold, and mental stress, renal blood vessels may spasm or become congested, causing the permeability of the glomerular filtration membrane to increase, causing a large amount of protein to "leak through the net." Normal pregnancy urine protein may be slightly increased, which is related to body position and renal flow.

It is related to increased volume and increased glomerular filtration rate. Functional proteinuria will disappear on its own after the cause is eliminated. Therefore, it is also called reversible proteinuria or transient proteinuria.
