What is Hyperoxaluria?

Primary hyperoxaluria (PH) is a group of rare disorders of glyoxylate metabolism, that cause the overproduction of endogenous oxalate. In high concentrations, oxalate tends to form calcium oxalate crystals in the renal tubules, leading to the formation of kidney stones, nephrocalcinosis or both. Three biochemically defined types of PH exist of which type 1 (PH1) is by far the most prevalent, based on clinical studies, and has the worst prognosis.

Secondary Hyperoxaluria: is due to excess exogenous oxalate due to intestinal diseases or diet. It is the most common form of hyperoxaluria .
