Nephrotic syndrome is a disorder
where the kidneys have been damaged, causing them to leak protein from blood
into the urine. It is also termed as Nephrosis.
The causes of nephritic syndrome are progressive glomerulonephritis,
disease such as diabetes, collagen disease or drug reactions, from exposure to
heavy metals, or even from a reaction to toxin venom following a bee sting.
It is characterized by massive oedema and protinuria, hypoalbuminemia
(low levels of albumin in blood), hypercholesterolemia (high cholesterol levels
in blood) and abnormal bone metabolism. Pedal (foot) and periorbital (around
the orbit of the eye) oedema and ascitis (fluid in abdominal cavity) are
common. The continued loss of protein may cause tissue breakdown and lead to
malnutrition.
As the disease progresses,
calcium or phosphate levels in blood maybe altered due to altered Vitamin D
levels, resulting in oesteomalacia.
The major objectives of dietary management of this condition are to
control and correct protein deficiency and correct and prevent oedema and
maintain adequate nutrition to afford better resistance to infection.
The dietary guidelines for nephritic syndrome are as below.
