What is the cause of bubbles in urine? Beware of foamy urine

If there is foam when urinating, you should be alert to the possibility of foamy urine. Normally our urine is transparent. If there are some diseases in the body, it will cause foamy urine. Common ones include cystitis, liver and kidney diseases, and diabetes. You must check and confirm the diagnosis in time.

1. Causes of foamy urine

1. In case of liver and kidney diseases, the bilirubin or protein content in urine increases, the surface tension of urine increases, and more bubbles may be produced during urination;

2. Bladder diseases such as cystitis, bladder cancer, etc., or other urinary tract infections can easily change the composition of urine and produce bubbles;

3. In diabetes, the content of urine sugar or urine ketone bodies increases, the acidity and alkalinity of urine changes, and the surface tension of urine increases;

4. When there are gas-producing bacteria in the urinary tract, bubbles may be produced in the urine;

5. Couples who have been separated for a long time and have stopped having sex for too long; those who are frequently sexually excited will have more bubbles in the urine due to the increased mucus secretion of the bulbourethral glands and the increased surface tension of the urine. In addition, when urination is urgent, the urination pressure increases and the urination rate increases, which increases the surface tension of the urine and increases the number of bubbles.

In short, there are many reasons for bubbles in urine, but when there are a lot of bubbles in the urine, the bubbles are large and last for a long time, you should go to the hospital for examination as soon as possible.

2. Is foamy urine a sign of kidney disease?

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.

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.
