Can you explain how parathyroid hormone injections make bones stronger when too much parathyroid hormone made by the body weakens bones?

Can you explain how parathyroid hormone injections make bones stronger when too much parathyroid hormone made by the body weakens bones?

Good question!: Parathyroid hormone (pth_ causes two main effects - a decrease in phosphorous in the blood, and an increase in calcium. If a body makes too much PTH (constant, high levels) it will leach the calcium from the bones to keep the blood levels up. Injections, however, are intermittent, lower concentrations that can stimulate bone strengthening by absorbing the calcium in the bood. ...Read more

Hormone (Definition)

A hormone (from greek ὁρμή, "impetus") is a chemical released by a cell or a gland in one part of the body that sends out messages that affect cells in other parts of the organism. Only a little amount of hormone is required to alter cell metabolism. In essence, it is a chemical messenger that transports a signal from ...Read more

Can you tell me how the parathyroid hormone increase release of calcium from the bone?

Parathyroid: Parathyroid hormone and calcium are linked.
If parathyroid hormone increases so will calcium in most circumstances.

If your doctor has discussed calcium and parathyroid hormone but you have not understood it, or it has never been discussed with you, I strongly recommend you go online and read the many articles (easy to understand) that discuss links between calcium and parathyroid hormone. ...Read more

Parathyroid hormone at 170pg/ml, vit d at 8ng/ml, calcium serum 10.2 yesterday and 9.1 today, bone mineral density t-score -1.5. What does this mean?

Parathyroid hormone at 170pg/ml, vit d at 8ng/ml, calcium serum 10.2 yesterday and 9.1 today, bone mineral density t-score -1.5. What does this mean?

Bones, Vit D: This is complex, and a precise answer cannot be given on line. Several thoughts: the PTH is high. But this may not reflect anything wrong with the parathyroid glands. Low vit d will result in a reflex increase in pth, and usually the serum ca stays normal, but there is increased bone resorption. Why is the vit d so low? ...Read more

If the body has enough calcium in it will it still release the parathyroid hormone?

If the body has enough calcium in it will it still release the parathyroid hormone?

Yes: Pth levels may be lower when serum calcium is very adequate, but without PTH the body cannot maintain the homeostasis. Pth is needed to make active vitamin d which helps the gut absorb calcium and phosphorus. Pth also regulates the balance between calcium and phos among other important things. ...Read more

What are the symptoms of excessive secretion of parathyroid hormone?

What are the symptoms of excessive secretion of parathyroid hormone?

Many symptoms: Parathyroid hormone is responsible for regulating calcium level in blood. The most common cause of hyperparathyroidism is a growth on your parathyroid gland causing overproduction of this hormone. If high, it will raise calcium level in your blood causing osteoporosis, kidney stones, kidney problems, bone pain, constipation, abdominal pain, psychological problems... ...Read more

What vitamins in a persons body can affect breathing. Muscles if calcium and magnesium are good but have elevated parathyroid hormone?

What vitamins in a persons body can affect breathing. Muscles if calcium and magnesium are good but have elevated parathyroid hormone?

Whoa: Your breathing muscles need no special vitamins beyond what you'll get with a halfway reasonable diet. What concerns me is your having an elevated parathyroid hormone. Either you have a parathyroid adenoma / hyperplasia which is really serious, or you are vitamin d deficient. You need to address this. You'll feel much better. Again, please forgive my frankness & do right by yourself. ...Read more

Can you tell me how could the parathyroid hormone decrease the loss of calcium from the kidneys?

Can you tell me how could the parathyroid hormone decrease the loss of calcium from the kidneys?

Calcium reabsorption: Hi. We filter a lot of our blood calcium into the urine, but the body can't afford to lose that (along with many other filtered goodies), so the kidneys have evolved means to regulate reabsorption out of the urinary filtrate back into the bloodstream. PTH binding to the PTH receptor (cAMP mechanism) activates calcium transporters in the distal tubule so the calcium is recovered. ...Read more

How does a lack of parathyroid hormone cause hypocalcemia?

How does a lack of parathyroid hormone cause hypocalcemia?

Calcium from bones: Most of the calcium in your body is in your bones. Parathyroid hormone releases ca from your bones to maintain a constant blood level. With most hormone deficiencies, we give back the missing hormone (eg. Diabetes, insulin). But PTH is not available as a treatment. So hypopara is treated with vit d, ca, and other meds. It is hard to regulate, and you need a doc experienced with this. ...Read more

High levels of calcium in my blood and my parathyroid hormone is off. Is this cancer.?

Not necessarily: Primary hyperparathyroidism and malignancy are the most common causes of increase serum calcium, accounting for more than 90 percent of cases. There are ways to differentiate one to the other (check intact pth, PTH related peptide etc). You should see your doctor and have further blood work-up and discussion in management of the problem. ...Read more

How will parathyroid hormone affect vitamin d absorption?

How will parathyroid hormone affect vitamin d absorption?

Vit D helps the: Intestines absorb calcium. However, the vitamin d must first be activated or by parathyroid hormone (pth). Once activated, vitamin d acts to greatly increase the amount of calcium that the intestines can absorb from food, sometimes by as much as two to four times. The body can either make its own vitamin d using a process that requires sunlight or obtain vitamin d directly from the diet. ...Read more

Do you control parathyroid hormone secretion using casr antagonist?

Her how it works: The g protein-coupled, seven-pass transmembrane molecule present in the parathyroid gland and kidney controls calcium homeostasis by releasing parathyroid hormone (pth). Manipulating calcium-sensing receptor (casr) using small-molecule allosteric modulators can affect PTH secretion. ...Read more

How are calcium blood levels affected by increased amounts of parathyroid hormone?

How are calcium blood levels affected by increased amounts of parathyroid hormone?

Hyperparathyroidism: The parathyroids make a hormone, PTH, which mobilizes calcium from your bones and keeps blood calcium normal. Overactive parathyroids make too much PTH, raising blood Ca, and leeching Ca out of your bones (Osteoporosis) and too much gets into kidney (kidney stones). Kidney disease can cause this, but often it is from an abnormal parathyroid gland that must be removed surgically. ...Read more

What hormones cause calcitonin and parathyroid hormone to be released? I know blood ca level has to do with it, but what hormones cause their release?

No hormones: Parathyroid hormone is released as a response to your calcium level (low calcium causes increased PTH). It is not regulated by any particular hormones. Calcitonin is a hormone that has no obvious function in humans (as opposed to fish). It is made in the thyroid gland, but people who have had their thyroid removed do not need calcitonin to remain normal. ...Read more
