Are Too Much Calcium in the Blood and Parathyroidism Related?


------------------------------------------------------------------------------

QUESTION:  After a recent blood tests, I was told that I have too much calcium
in my blood.  I'm confused because I thought calcium is good for you.  I've
also been told I have parathyroidism.  Are the two conditions related?  Please
clarify.

------------------------------------------------------------------------------

ANSWER:  You're right.  Calcium is good for you, but, like anything else, too
much of it isn't healthy.  More importantly, excessive calcium in the blood is
a signal that something is wrong and should be investigated and possibly
treated.
     You say you have parathyroidism, but I think you mean
"hyperparathyroidism."  Hyperparathyroidism, or HPT, is caused by the
hyperactivity of the parathyroid glands, and too much calcium in the blood
is characteristic of the person who has hyperparathyroidism.  Other
conditions can cause too much calcium in the blood, but it is very common
to see hyperparathyroidism and hypercalcemia, or high levels of calcium in
the blood, together.
     HPT is being diagnosed with greater frequency now than ever.  It appears
that it is no more common now than it has been in years past, it is just
diagnosed more frequently.  Often it is unexpectedly identified in patients
when a routine blood test reveals higher than normal amounts of calcium in the
blood.  The patient may or may not have symptoms.  It is twice as common in
women as men, and is seen most often in women aged 40 to 60.
     More than half the people with HPT diagnosed in routine screening tests
have "primary HPT," which means the cause is not known and the only problem
that can be found is simply the higher than normal levels of calcium in the
blood.  In other individuals the cause may be a tumor of the parathyroid
gland, which cause the gland to malfunction and secrete more hormone than it
should.  Other forms of cancer can mimic HPT, but this is fairly uncommon.
Those persons whose primary HPT is discovered during routine labwork usually
require little or no treatment.  If the problem is caused by a tumor on the
parathyroid gland, surgical treatment will probably have to be considered.
     People with HPT vary widely in their symptoms.  Those with primary HPT
often have vague symptoms that are not severe enough to motivate the
individual to seek medical attention.  Symptoms most frequently reported are
fatigue, irritability and mild gastrointestinal distress such as nausea and
constipation.
     The decision on when or how to treat depends upon the age and the
general physical health of the patient, and the severity of the symptoms.
Surgery on the parathyroid gland is an option for some, but it should not be
undertaken lightly.  Surgery to correct hyperthyroidism is delicate and not
always successful.
     Liberal intake of fluids and salt are often prescribed for the person
with mild primary HPT, because this helps the body excrete excess calcium in
the urine.  Sometimes, limiting intake of calcium and Vitamin D is
recommended.  Do not treat yourself by adding salt to your diet or limiting
your calcium and Vitamin D unless you have been thoroughly evaluated by your
doctor.  Calcium and Vitamin D are essential to health, and limiting your
intake of them should be done with your doctor's supervision and advise.
