DR. C’S JOURNAL: BENEFITS OF PARATHYROID HORMONE

Hormones, Vitamins, and minerals all have extensive interactions in the give-and-take of the bodies’ ballet of homeostasis. No where is this more clear-cut than the interplay of parathyroid hormone, vitamin D, and calcium.

Although it has many other actions in the body, calcium is best known as the prime component of our bones. It is essential for making them healthy and strong. The bones act as a storehouse or vault for the bodies calcium. The parathyroid hormone is the key that unlocks the vault to release the calcium so it can perform its many other roles in the body. An elevation of the calcium in the blood stream shuts down the parathyroid Glands.

Parathyroid hormone also acts to instruct the body to absorb more vitamin D, just as the vitamin D causes the intestinal tract to absorb more calcium. The parathyroid glands are in the upper poles of the thyroid which as we mentioned before sits astride the windpipe.
Sometimes the parathyroid gland develops an adenoma which causes too much secretion of parathyroid hormone.

This results in an excess of calcium in the body and a variety of symptoms, such as joint pain muscle weakness, fatigue, nausea and vomiting. One of the technicians in my medical practice developed hyperparathyroidism. It was detected by a metabolic panel, which showed an elevation of serum calcium.

This discovery, early in my practice, made me a big fan of metabolic panels when patients have general symptoms. Her condition, a parathyroid adenoma, was cured by surgery. Conversely, surgery for an overactive thyroid can sometimes accidentally remove the parathyroid glands if the surgeon isn’t careful. The parathyroid glands are tiny, but they perform a huge function.

BLOOD TESTS: THE BENEFITS THAT “COMPREHENSIVE METABOLIC PANELS” REVEAL

One of my nurses who was usually in good health developed chronic complaints. She felt tired all the time and had a variety of aches and pains. She has been going through menopause for a long time but this set of problems seem different. Then she broke her arm after sustaining a minor fall. An investigation was in order. I should order some tests, but which ones?

Anemia would explain the fatigue so a CBC was a no brainer. With the surprise fracture, I wanted to cast the net wider, so I ordered a comprehensive metabolic panel.

This is an automated test that was a good value for the amount of information provided, I thought.

Nobody was more surprised than I when the test provided results that were the key to her very rare diagnosis. Her serum CALCIUM was very high, and her alkaline phosphatase was also elevated.

Further evaluation showed her diagnosis to be PRIMARY HYPERPARATHYROIDISM.

Removal of her abnormal parathyroid gland was curative. I have been a big fan of the Comprehensive Metabolic  Panel ever since.

The Panel of 14 tests includes:

  • Glucose – an essential test to check in Diabetes, Seizures and Coma.
  • Sodium, Potassium, Chloride, and CO2 and the associated Anion Gap – can be abnormal in a variety of accidents, and other conditions.
  • BUN and Creatinine – cleared by the kidneys, and become elevated in Renal, or Kidney conditions.
  • Calcium and alkaline phosphatase – reflect bone metabolism, and are sensitive to Vitamin D and parathyroid hormone, as in my nurses case.
  • Albumin and Globulin – important blood proteins. Globulins contain the   important immunoglobulins. A variety of conditions will influence their values.
  • AST (SGOT) and ALT – elevated in liver disease

Type in “Comprehensive Metabolic Panel” in google, and choose from the variety of “hits” to get more information about this “ Sherlock Holmes’ Magnifying Glass” for Physicians.

Medicine would be hard pressed to do without it!
