Stop focusing on just your GFR when you have kidney disease.
There’s another important marker you shouldn’t overlook: PTH.
Here’s something I see quite often with my clients.
When we begin coaching, I ask them to include PTH in their initial lab work.
Some have been living with kidney disease for YEARS and have never had this marker checked.
And when they finally get it tested, some are surprised to see that their numbers are out of range.
So, what exactly is PTH?
PTH stands for parathyroid hormone. It’s a hormone that helps regulate the calcium and phosphorus levels in your blood.
Here’s where your kidneys come in:
Your kidneys help regulate phosphorus and activate vitamin D, which helps your body absorb calcium.
When kidney function declines, these processes can become disrupted.
As phosphorus balance and vitamin D activation change, your body may produce more PTH to compensate.
Over time, persistently elevated PTH can contribute to bone loss and weakened bones.
This is one reason why managing CKD involves more than just watching your creatinine and GFR.
Your kidneys affect so much more than filtering waste.
