PTH is ParaThyroid Hormone

PTH is ParaThyroid Hormone.  This is not Thyroid.  The Parathyroid glands live next to the thyroid gland.  They are like 4 spots on the butterfly-shaped thyroid gland’s wings.  But their function is totally different

High PTH warns us that not enough Calcium is being absorbed from diet and/or supplements.  When not enough calcium is being absorbed, the blood calcium level drops. If the blood calcium drops too low, you will die.  The Parathyroid glands prevent that.  The Parathyroid glands’ job is to steal calcium from your bones.

A patient was very disappointed recently, that his Bone Mineral Density (BMD) had NOT IMPROVED, despite anabolic medication for his Osteoporosis.  The reason for failure became obvious as soon as we reviewed his diet and supplements.

His total Calcium intake is 500 mg daily in diet, with NO supplements.  He prefers to avoid supplements as “unnatural”.   This is OK.  Natural Calcium in Foods is actually better than supplements.  But you have to consume it.  And you need to take it properly spaced throughout the day.

It’s even harder to suddenly be a Big Brother instead of an Only Child.  RJ now has to do both.  He turned 3 years the day after his new sister turned 2 months.

Grammy and Papa Jay spent a long weekend visiting RJ and baby sister Gwen.  The result was Blue Zones all around.

Fracture Risk is much more than Bone Mineral Density (BMD) or t-score.  Many medical conditions cause osteoporosis and fractures.  Blood tests can detect those medical problems.  This is the post on CMP.

Albumin is the major protein in the blood.  A large portion of the calcium in the blood is bound to albumin.  What is important is “free calcium”, so a mildly low calcium combined with a low albumin is less of a problem for heart and nerves. However, a low albumin generally means poor nutrition, especially too little protein intake, and protein is the major component of bone, so too little protein is a problem.
