My mother (73, overweight, gave up smoking in 1978 but drinks more than ideal) started a cough about 4 months ago and lost appetite, lost weight, became nauseus, bit depressed adn forgetful. About 3 months ago a minor exertion resulted in a fracture in a spinal vertebra and about 1 months ago a minor knock resulted in broken wrist and she was diagnosed with osteoporosis and given calcium that made her very sick so she stopped. Recently also diagnosed with start of kidney stones. The cough, loss of appetite, nausea and weight loss has continued and worsened. She ended up in hospital over christmas almost in a coma and on a drip. they have now given her furosemide for congestive heart failure and this is some relief to the cough and appetite issue.
However I think she has undiagnosed hyperparathyroidism but can't persuade her or her doctors to investigate this because she had normal blood tests in november. However I am aware that 7-12 % of HPT cases show blood tests within normal but still she and her doctors seem to be discounting and only dealing with Congestive heart failure.
Am i right to assume possible HPT problem, how do I get doctors to investigate this?
