If you suffer from nephrotic syndrome, your kidneys let theprotein leak out in your urine. When this happens, thewater in your blood escapes from blood vessels andcapillaries into the tissues of your body, which causesswelling (oedema). Your kidneys may become inflamed.Any swelling will be made worse if your kidneys try to holdmore salt than they should to make up for losing theprotein.
What is Nephrotic Syndrome?
N e p h r o t i c S y n d r o m e
Nephrotic syndrome is a rare disease that affectsthe kidneys. Most people have two kidneys, oneon either side of the body just beneath theribcage. Healthy kidneys filter the blood. Theyallow small particles of waste products and waterto go through, which are passed as urine. Thekidneys hold on to larger particles such asprotein. Holding protein inside your body, insteadof letting it pass through, is important for goodhealth. The most common protein is calledalbumin and it should stay in your bloodstream.Albumin holds water in the bloodstream as itcirculates around your body.

If you use them in the way your doctor has toldyou to, they can be very effective. Manufactured steroids areoften prescribed to children when they are first diagnosed withnephrotic syndrome. This reduces inflammation in the kidneysand helps children to keep more protein (albumin) in theirbodies. After between l and 2 weeks of steroid treatment, theirurine tests should show less or no protein. This is a sign thatthe treatment is working. People taking steroids should carrytheir medication alert card at all times. You should not stophaving steroid treatment without first talking to your doctor.
