Proteinuria is actually the term used to describe presenceof excess amount of protein in urine. There is always a small amount of thesubstance in urine and you shouldn’t be alarmed with it. But, in case when the labresults of your urine show high levels of protein it might indicate the problemwith your kidneys. Normally, kidneys are not able to filter proteins because theyare too big to pass thorough the glomeruli of the kidneys. So, if proteinsappear in urine, it may mean that glomeruli or the kidneys don’t function well.
Children suffering from proteinuria may not have any symptomsat all. Patients are commonly asymptomatic in early stages or if the protein inurine is just slightly higher than normal. However, many patients experiencefoamy or bubbly urine and if you notice it you should know this is one ofcommon signs of protein in urine. Edemas or water retention are also possible symptoms, causedby the loss or high amounts of protein. Children suffering from this problemmay experience swelling of different parts of the body, especially: the face,hands, abdomen or the feet.
Causes of Proteinuria in Children
Protein in urine affects both children and adults. Mild transientproteinuria can be caused if a child is exposed to some kind of stress, fever, coldor heat. Too much physical activity and exercise, as well as dehydration mayalso lead to temporarily increased amount of protein in urine.
Another medical condition which may lead to slightlyelevated level of protein in urine in children is “orthostatic proteinuria”. Thisis benign condition and children and teenagers suffering from it usually haveheightened level of protein in urine during the active part of the day. Doctorsdon’t know what causes this condition, but it is considered to be completelyharmless and it is not a sign of any kidney problem.
Infections of the urinary tract and different diseases ofthe glomeruli or kidneys are known to lead to high levels of protein inchildren’s urine. Diabetes may be responsible for persistently high amount ofprotein in urine and therefore cause damage to the kidneys. Nephrotic syndromeis also associated with heightened level of protein in urine.
How is Proteinuria in Children Treated?
The first thing the doctor will do is to properly diagnosethe problem and find out what have caused it. Orthostatic proteinuria doesn’t requireany treatment, but other conditions must be properly looked into. Sometimes,doctors may need dome specific tests or kidney biopsy to rule out certainconditions that might have caused protein in urine. Infections of the urinarytract are commonly cured with a course of antibiotic drugs, while the reductionof salt intake may improve present swelling.
