Bubbles in Urine And Kidney Disease

Various illness condition can cause bubbles in urine and kidney disease is one of them. In kidney disease, bubbles in urine is the clinical manifestation of proteinuria which occurs when kidneys fail to stop protein from being leaked. For proteinuria caused by kidney disease, the bubbles in urine are small and exist for a long time. Also, most of them time, the more bubbles there are in urine, the more serious the kidney disease is.

What are the harms for bubbles in urine caused by kidney disease?

Bubbles in urine indicate massive protein in urine, which is a abnormal illness condition. Protein is essential for our life and our body need them to build up muscles, against harmful substances and keep skin, hair and nails healthy and so on. When massive protein are lost from urine, we are at high risk to suffer from malnutrition, poor immunity, anemia, growth retardation, swelling, hypoproteinemia and hyperlipidaemia and so on.

In our daily life, foods like beans, milk, fish, egg white and lean meat all are high in protein. Although protein plays an important role for a normal life, we must be cautious about the protein intake as excessive protein will increase kidney burden and worsen kidney condition. Therefore, for kidney disease patients, calculating protein intake very day is very necessary.

How to deal with bubbles in urine resulted from kidney disease?

Normally, protein are stopped from being leaked by glomerular filtration membrane, an important part of kidney. This membrane works by displaying mechanical barrier and charge barrier. Mechanical barrier only allows protein with a certain size to pass through and charge barrier only allows protein with negative charge to pass through. Under the effects of these two barriers, only a small amount of protein can pass through the filtration membrane. When these filtrated protein pass by renal tubule, most of them will be reabsorbed by renal tubule. So in normal case, no protein can be detected in urine. However, once glomerular filtration membrane or renal tubule is damaged, much more protein will leak out. And generally speaking, proteinuria caused by damaged glomerular filtration membrane is usually more seriously than that caused by damaged renal tubule. To solve proteinuria problem, the best and permanent method is to repair kidney damages. As long as the damages are repaired, protein stops leaking and also bubbles in urine reduces.
