📖What is Nephrotic Syndrome?
Nephrotic syndrome is a kidney disorder characterised by significant damage to the tiny filtering units within the kidneys, causing large amounts of protein to leak from the blood into the urine. This protein loss leads to low blood protein levels, which in turn causes fluid to shift out of blood vessels into surrounding tissues, resulting in the characteristic widespread swelling associated with the condition. The syndrome can occur at any age, with certain causes being more common in children and others more typical in adults, and can result from a primary kidney disorder or occur as a complication of a systemic disease such as diabetes or lupus. Along with swelling, the significant protein loss disrupts the body's normal balance of fats and increases susceptibility to infections and blood clots. Treatment addresses both the underlying cause where identifiable and the complications arising from significant protein loss, with many cases, particularly in children, responding well to medication.
