Nephrotic syndrome is a conditionthat causes the kidneys to leak large amounts of protein into the urine.This canlead toa range of problems, including swelling of body tissues and a greater chance of catching infections.

Although nephrotic syndrome can affect people of any age, it'susually first diagnosed in children aged between two and five years old. It affects more boys than girls.

Around1 in every 50,000 children are diagnosed with the condition each year. It tends to be more common in families with a history of Indoor allergy or those ofan Asian background, although it's unclear why.

The symptoms of nephrotic syndrome can usually be controlledwith steroidmedication. Most children with nephrotic syndrome respond well to steroids and aren't at risk of kidney failure.

However, a small number of children have congenital (inherited) nephrotic syndrome and usually do less well. They may eventually have kidney failure and need a kidney transplant.
