Researching PTH and Calcium based on Kirmy's comments in a different thread on diet and a note about degenerative changes found in my fairly young spine and came across the following chart and explanatory language which I think is very helpful. It is from: http://www.parathyroid.com/hyperparathyroidism-diagnosis.htm
My last PTH was 98 and Calcium was 9.2, putting me on this chart right in the purple Gastric Bypass Surgery section...
High Parathyroid Hormone Levels in Patients with Intestinal Absorption Problems, Such as:
Gastric Bypass Surgery, and Celiac Sprue, and Crohn's Disease.
There is a growing group of patients who have dramatic life-long problems absorbing calcium in their diet. These patients are now illustrated on our graph in the purple area. These patients have a problem with their intestines that prevent them from absorbing calcium well. Since they don't (can't) absorb calcium from their diet, their NORMAL parathyroid glands will do what they are supposed to do... maintain a proper calcium level in the blood. There is only one thing these normal parathyroid glands can do... all four glands enlarge and produce lots of PTH which removes calcium from the bones--its the only place to get the calcium. The blood calcium is therefore maintained appropriately in the normal range (usually low normal between 8.2 and 9.2, but can be as low as 7.0) at the expense of taking calcium out of the bones. Thus these patients have very significant osteoporosis, high PTH levels, low normal calcium and high alkaline-phosphatase (shows increased bone destruction). These patients do NOT need their parathyroid glands removed. They have developed a total-body calcium deficit due to a longstanding inability to absorb calcium through their intestines.
The most common people in this purple group are 1) those who have had gastric bypass surgery for weight loss, 2) those with Celiac Sprue, 3) those with Crohn's disease, and 4) those who have had a significant part of their intestines surgically removed. Patients who have had gastric bypass surgery will eat food which then is routed around most of their stomach and the first part of their intestines (thus the term 'bypass'). Virtually 100% of these patients will have malabsorption of calcium. Thus, all patients who undergo gastric bypass for weight loss must be taking calcium and vitamin D every day or they will develop a total body calcium deficit which leads to overproduction of PTH by normal parathyroid glands leading to severe osteoporosis and the problems described here. Do NOT remove these NORMAL functioning parathyroid glands even though they are making lots of PTH... they are doing so appropriately. The treatment for these patients is to fix their calcium deficit by giving them daily calcium and Vit D pills...
