What does foamy urine mean

Since it consists of over 90 percent water, healthy urine is usually pale yellow and odorless. Various factors, such as the amount you drink, can influence the color and texture of the urine. People who drink little usually have darker urine than someone who drinks a lot. But what about foam in the urine and what should you do if you discover it?

What does foam in the urine mean?

Depending on the strength of the urine stream, our urine can sometimes foam more and sometimes less. In most cases, however, foam is a sign of protein in the urine. Protein is harmless in small amounts and can also be found in the urine of healthy people. However, if the amount of protein in the urine is too high, it is called one Proteinuria. This can be caused by a variety of circumstances, including some illnesses.

Foam in the urine: diseases as a cause

If there is short-term protein in the urine, it is usually harmless. However, if the protein content is too high in the long term, this is an indication of damage to the kidneys. The kidneys are responsible for filtering our blood. If there are already too many proteins in the blood plasma due to illness (Prerenal proteinuria) or there is a dysfunction of the kidneys (Renal proteinuria) cannot work properly, you can no longer keep large proteins such as albumin out of the urine. The following diseases of the kidneys can lead to proteinuria:

  • Kidney damage
  • Inflammation of the kidneys
  • kidney damage caused by diabetes

In rare cases, proteinuria can also be triggered by other diseases. These include:

  • Heart failure
  • high blood pressure
  • malaria
  • tuberculosis
  • Autoimmune diseases of the liver or lungs

Other causes of excess protein in the urine

There is not always a serious illness behind the foam in the urine. Certain medications like Antibiotics or Drugs used to treat cancer used can be causes of proteins in the urine. Also one heavy physical exertion through work or sport, stress, fever, and extreme temperatures can be causes. In children and adolescents, protein can appear in the urine during growth phases.

The cause of foamy urine should always be clarified

It doesn't always have to be a serious medical condition, but as soon as you notice foam in your urine, you should see a doctor. A urine sample can be used to determine the amount of protein in the urine. In most cases, benign proteinuria does not require treatment. If a disease-related proteinuria caused by kidney problems is found, you will be referred to a so-called nephrologist, a kidney specialist.
