How long does it take for proteinuria foam to disappear?

Proteinuria is a common form of urine. On the surface, proteinuria means excessive foam, but excessive foam does not necessarily mean proteinuria. Proteinuria is divided into physiological proteinuria and pathological proteinuria. Physiological proteinuria is often caused by strenuous exercise or body fever, especially when getting up early in the morning. The concentration of foam in urine is the highest. If the foam does not disappear for more than three minutes, it may mean the occurrence of proteinuria. Of course, this is not absolute, and you still need to go to the hospital for examination in time.

These cases of foamy urine are not related to kidney disease :

1. Increased foam in urine due to rapid urination or high urination position. This type of urine foam is mostly caused by the mixture of air and urine, and the foam will disappear easily.

2. Increased urine foam caused by high urine concentration. Urine concentration increases the concentration of urine components and makes it easier to form foam.

3. Physiological proteinuria, increased urine foam caused by fever, strenuous exercise, etc.

4. The presence of semen in the urethra: If there is semen in the urethra of men, it can cause foamy urine; frequent sexual excitement increases the secretion of mucus by the bulbourethral glands, causing nocturnal emission, etc.

In the above four situations, the urine foam will disappear within 3 minutes at most. If it exceeds this time, it means that the kidneys have varying degrees of damage.

What kind of urine indicates more serious kidney damage?

1. Early kidney damage, foam appears in the urine

In the early stages, a small amount of urine foam appears, which takes a long time to disappear. At this time, the patient's condition is actually very mild, and the kidney damage is still in a reversible state. At this stage, also commonly known as the nephritis stage, active treatment can control the disease and achieve a cure. Oral Chinese medicine can be used to reduce urine protein.

2. Kidney damage worsens, with large amounts of foamy urine and white precipitates in the urine

When a large amount of foam and white sediment appear in the urine, kidney damage has reached a very serious level. This stage can be said to be the critical period for the treatment of kidney disease. If it is controlled, the kidneys can be saved. If it is not controlled, the kidneys will gradually become necrotic until they become completely fibrotic.

3. The kidneys are severely damaged, with obvious foam and flocculent sediment in the urine

At this time, a large amount of hormones is needed to quickly control proteinuria, but once the hormones are stopped, proteinuria will recur. The principle of treatment at this time is to preserve as much renal function as possible.
