6. Proteinuria
There is a condition in which protein is released in the urine in high amounts which are usually released but in small amounts, this condition is called Proteinuria. It is a condition characterized by the presence of greater than normal amounts of protein. It is usually associated with some kind of disease or abnormality but may occasionally be seen in healthy individuals.
Plasma, the liquid portion of blood, carries or contains many different proteins. When these levels become high, the urine can appear bubbly. This can be a sign of an impending problem in the kidneys as it is not functioning as it should be — to properly filter the urine and make sure that it doesn’t release too much protein.
Other factors may help contribute to kidney filtration problems along with toxins, infection, or trauma to the kidneys. Healthy kidneys do not allow a great amount of protein to pass through their filter. But some filters are damaged that it let proteins leak from blood to urine.
