PKD and vitamin D deficiency

[OnTheMend216]

Is it possible for my PKD to be a factor in my severe vitamin D deficiency even if my kidneys seem to be working fine? I just left a message with my PCP asking if maybe it'd be a good idea to check my kidney function, as I haven't in a few years. Also, my BP was higher than normal when I went to the doctor the Fri before last. Since the kidneys generally help to stabilize BP and to convert D3 & D2 into usable vit D for the body, does it make sense to have them checked? Also, is it normal to have updated ultrasounds on the kidneys and liver? I haven't had one since I was 30 (turning 40 next month).

Thank you, Dr. Sharma!
I'm also hypothyroid, which has been more or less under control since I was diagnosed with it at age 5. I only found out about the PKD when I had an ultrasound at 30, since my dad had it (he died last July after being on dialysis for 17 years; he had a massive stroke, and his body just couldn't tolerate dialysis any more). I have an appt. with a nephrologist on Feb 19th and some lab tests to take before that. I'll be sure to write again if (or rather when) I have more questions. Thanks again!

Hello and hope you are doing well.
The common causes of vitamin D deficiency are chronic kidney disease, hypoparathyroidism, severe liver disease etc.In PKD there may be osteomalacia and vitamin D deficiency. A common complication of polycystic kidney disease is high blood pressure. Kidney failure is another complication. It may be best to get an evaluation done. A clinical examination and work up like ultrasound kidney, ureter bladder, and kidney function tests, vitamin D levels and calcium may be done. Treatment will depend on the cause. Do write to me again with more queries.
Best luck and regards!
