Ionized Calcium 4.65, PTH 133, Calcium 10.3, Vitamin D 7, Phosphorus 4.9, recurrent Kidney stones. Thyroid lobe, two parathyroids removed in 2004.

Uncertain: These test results don't add up to a straight forward answer. However, I would be concerned about the possibility of recurrent primary hyperparathyroidism. You should take Vit D to eliminate Vit D deficiency as a cause for high PTH levels. Once this is done, if you still have high PTH with high calcium levels, you have recurrent primary HPTH and will need surgery again.

Kidney (Definition)

The kidneys are paired organs that lie on either side of the vertebral column. Part of their critical functions include the excretion of urine and removal of nitrogenous wastes products from the blood. They regulate acid-base, electrolyte, fluid balance and blood pressure. Through hormonal signals, the kidneys control the ...Read more

Mom's calcium level 13, renal function 50%, pth a bit low. Magnesium/phosphorus normal. Vitamin D 1000MG bid. Bone pain, tired, confused -any Ideas?

Mom's calcium level 13, renal function 50%, pth a bit low. Magnesium/phosphorus normal. Vitamin D 1000MG bid. Bone pain, tired, confused -any Ideas?

Hypercalcemia: Calcium Lvels are VERY HIGH. Need HOSPITALIZATION to bring down Calcium levels specially if she is confused and symptomatic. IPTH can also be checked, Get CT scan of NECK and Chest as well. But bottom line is that HYPERcalcemia at this level must be investigated soon.

What might cause my liver and kidneys to not extract any vitamin d?

What might cause my liver and kidneys to not extract any vitamin d?

They do not extract: The liver and kidneys do not extract vitamin d, they activate it into forms that are usable by the body. Native vitamin d has no effect until it is activated. If your level is low it is because you are not getting enough or you are not absorbing it or you are not getting enough ultraviolet exposure from the sun.

Can you tell me how kidney activate vitamin d?

Can you tell me how kidney activate vitamin d?

An enzyme.: The Vitamin D that we get from our diet and what is made in our skin with the help of sunlight is initially inactive and must become activated in order to exert its effects in our bodies. Healthy kidneys contain an enzyme called 1-alpha-hydroxylase that converts inactive Vitamin D into active Vitamin D.

What are the dangers of having a vitamin d level of 160 if the patient feels normal, in fact better than normal and no kidney damage?

What are the dangers of having a vitamin d level of 160 if the patient feels normal, in fact better than normal and no kidney damage?

Several: ....Bone loss, abnormal blood calcium, deleterious effects to the liver, kidneys and possibly heart and blood vessels. Like having high blood pressure, how the person feels just doesn't matter. You can have very high blood pressure, be at high risk for heart attack or stroke, and feel perfectly fine until a bad event happens. Safe vitamin d levels are between 30 and 80.

Hypercalcemia: You need a specialist some commentsloss of a kidney due to hypercalcemia uncommon generally dystrophic calcification due to a bad kidney like poly cystic disease hypercalcemia can have kidney issues make sure u are not toxic vitamin d or over replaced calcium parathyroid function needs to be looked at certain diseases like sarcoidosis can cause incresed d underlying kidney disease makes these wors.

What does lack of vitamin d have to do with kidneys?

What does lack of vitamin d have to do with kidneys?

Conversion to active Vitamin D: Vitamin d whether obtained from diet or from sun exposure must be metabolized first by the liver and secondly by the kidneys from a relatively inactive prohormone to the active form of vitamin d that is primarily responsible for its metabolic effects. In particular, the kidneys take 25 hydroxy vitamin d to 125 hydroxy vitamin d.

If my Vitamin D level is 19, do I need to have the kidneys, thyroid, or calcium levels checked?

If my Vitamin D level is 19, do I need to have the kidneys, thyroid, or calcium levels checked?

Likely need Vit. D: At 65, you likely have basic labs performed, and hopefully on a routine basis. Typical labs will give a basic exam on electrolytes and waste products. A Complete Metabolic Panel and thyroid test will give a view of organ function. Vitamin D has a large therapeutic index and the likelihood of it being low increases with age. B12 also follows this pattern.

I already take 3700 iu of vitamin d, why does it keep showing up that I am deficient? My thyroid and kidneys are fine.

I already take 3700 iu of vitamin d, why does it keep showing up that I am deficient? My thyroid and kidneys are fine.

Not enough D: It sounds like you are taking enough vitamin d to maintain healthy levels, but not enough to raise deficient levels into the healthy range. You may need to take very high doses of vitamin d for 3 months or more to get your levels into a healthy range. Other possibilities might include poor absorption of fat and fat-soluble vitamins like vitamin d, or taking steroids. Work w/ your doc on this.

I get kidney stones but I am also very low on active vitamin d. Will taking active vitamin d cause an increase in calcium thus more stones?

I get kidney stones but I am also very low on active vitamin d. Will taking active vitamin d cause an increase in calcium thus more stones?

D3 and stones: Vitamin D3, when activated by the liver and kidney, does enhance calcium absorption across the intestine. So, your kidney's excretion of calcium may increase. It is essential to know why you form stones. The standard prevention is high intake of citrate and fluids - get citrate from ReaLemon extract, 5 tblspn / day - and drink 4 liters fluid per day, avoid salt, reduce meat. Add 1000 IU D3/day.

Does vitamin d supplement increase possible kidney stones?

Does vitamin d supplement increase possible kidney stones?

Vit D toxicity: If you take a lot of Vit D, and I mean A LOT for a prolonged period of time, you can get vit D toxicity, which can raise blood calcium and potentially cause kidney stones. A normal daily supplement is not a problem. The treatment regimens typically used to treat low Vit D are not a problem.

1200 mg calcium w/ 800 iu vitamin d per serving (serving= 2 softgels) what vitamin to combine w/ to avoid another kidney stone ps I need my protein 2?

Magnesium, Vitamin K: Magnesium has been proven to dramatically reduce recurrence of kidney stones- research shows that taking magnesium reduces incidence of kidney stones 90-92%- it probably works best combined with vit b6 try about 600 mg of magnesium as glycerinate, citrate or taurate and 50-75 mg of b6. I feel everyone taking d should also take vit k, at least 1 mg/day- vit k makes sure calcium goes to your bones.

Low vitamin D - 7 High parathyroid- 133 Recurrent kidney stones Low normal ionized calcium 4.65 Calcium 10.3 Are kidney stones due to low vitamin D?

Low vitamin D - 7 High parathyroid- 133 Recurrent kidney stones Low normal ionized calcium 4.65 Calcium 10.3 Are kidney stones due to low vitamin D?

No: Hi. Nope, stones NOT due to low vitamin D. You should do an accurate 24-hour urine for creatinine (for validation), calcium, oxalate, citrate, phosphate, and sodium; UA for urine pH. Your total calcium looks a tad high; confirm total calcium and albumin, and ionized calcium. You should see an experienced endocrinologist or nephrologist for a thorough evaluation. Good luck!

I had regular check up done, cbc, liver, kidney, lipid, urine all normal. Should I test for Vitamin D deficiency? I read online that men should test.

I had regular check up done, cbc, liver, kidney, lipid, urine all normal. Should I test for Vitamin D deficiency? I read online that men should test.

Don't think so: There is no clear guideline regarding Vitamin D in younger people, the only solid recommendation is for older people with history of fall.
