Hello Everyone - My name is Tracey Porreca and I am the Hypophosphatasia (HPP) Division consultant for the MAGIC Foundation. I was lead here by a google alert about discussions regarding low alkaline phosphatase levels. First, some of what has been posted here about alkaline phosphatase (ALP) is true, but some needs adjustment. The hallmark of HPP is a low alkaline phosphatase level. If you look up the disorder HPP, most of what you will find discusses the more severe forms of it, usually obvious at birth or shortly after. However, there are milder forms of this disorder and it is possible to go well into your adult years (my father was in his 60’s) before you are diagnosed. As was mentioned, there are not a lot of things that can cause an ALP to be low, but if you do have a low ALP, it is imperative you have this investigated, and by someone who is familiar with HPP. My suggestion to those of you who have experienced low ALP levels would be to look back at your past labwork and see if you can find other low ALP’s. If your ALP is consistently low, it is very reasonable to assume you have this disorder. Some of the symptoms you might experience with HPP are some of the things that might lead you to start a ketogenic diet in the first place. I highly encourage you to look at 2 websites, and if you have any questions, please feel free to contact me. First, check out our website and my story for more information on the disorder: https://www.magicfoundation.org/Growth-Disorders/Hypophosphatasia/ And second, check out this website which was actually developed for physicians, but has a lot of useful info: http://hypophosphatasia.com/hcp/ Please don’t overlook this. There is a treatment available and with proper diet and treatment you can do well. This is genetic so it is very possible if you have this, there are others in your family who are walking around with it, not knowing they have it either. The longer it is ignored, the more trouble it can cause. Please feel free to message me or email me from the MAGIC Foundation link above. Thanks
