This is Ben. Ben is almost 10 years old. He has
a condition called cushings which means that his body produces too many
steroids– this makes him more hungry and thirsty than normal. He was well
controlled on his treatment, but just before Christmas his owners noticed that
he was drinking a lot more than usual again (about 4 times his normal
amount). We checked his medications and found that his cushings was well
controlled, but on a routine blood sample we noticed that he had a raised blood
calcium level and a low blood phosphate level.
We had to take some further specialised blood tests which we
sent to an external laboratory. We diagnosed Ben with a rare condition
called primary hyperparathyroidism. This is a condition where the
parathyroid gland (which sits next to the thyroid gland in the neck) becomes
enlarged and produces too much parathyroid hormone resulting in Ben being
thirsty all the time.
He had an operation last week to remove his enlarged
parathyroid gland (see photo). We are happy to report that Ben has
recovered well at home and he is already back to drinking much less than before
his operation.
