Since my surgery my Alk. Phos. levels have increased quite a bit (2-3x normal). The doc says it can be a result of surgery or biliary obstruction disease. These aren't the only things a high level indicates but for my age and health apparently the most common. Others have pointed out other possible causes.
I have gall stones and I suspect I have a small stone blocking a portion of the common bile duct. It is hard to tell if it is or not because the ultrasound I just had done didn't find a stone (ultrasound resolution may have an effect though). I was supposed to go in to get another blood test today but got too swamped with work. I'm hoping my levels go down pretty soon, or it means more money to the doctors etc. as it would probably mean liver issues in my case.
I had no idea high levels indicated mets - something else to watch now. I learn something new here every day.
