Welcome to Take On PH1, a site dedicated to educating the primary hyperoxaluria type 1 (PH1) community.
PH1 can present at any time and at any age. When it does, we have resources for you.
Kidney stones are common in people with primary hyperoxaluria type 1 (PH1)
The most common symptom of PH1 is kidney stones that form due to oxalate overproduction in the liver.
The impact of PH1 goes beyond stones
This overproduction of oxalate can damage your kidneys, affecting their ability to filter waste from your blood.
PH1 tends to get worse over time
Because oxalate is constantly overproduced, it may continuously be doing damage, even when you don’t realize it.
