Thank you for your post, my name is Ellen and I am one of the Myeloma Information Specialists here at Myeloma UK.
I am sorry that no one, as yet, has replied, this may be because hyperparathyroidism is rare and no one on the forum has experience of it.
Both myeloma and hyperparathyroidism can cause raised levels of calcium in the blood, but this perhaps is where the similarity end.
The parathyroid glands produce a hormone that helps control the body’s calcium levels. In myeloma patients, calcium levels can be raised because of the effect myeloma can have on the bone.
Briefly, myeloma can thin and weaken the bone and in doing releases calcium from the damaged areas into the blood, hence levels are increased.
Myeloma is diagnosed using a whole range of tests and investigations – not just the calcium levels – and anyone suspected of having myeloma should be referred to a haematologist.
I hope this has helped and perhaps one of the forum users will come along with similar experiences.
However if you do have any questions that I can help with pease do not hesitate to get in touch either by email to askthenurse@myeloma.org.uk or by calling the freephone Myeloma Infoline on 0800 980 3332; I or one of my colleagues would be very happy to talk things through with you.
With best wishes
Ellen
