Hi & Welcome.
I can understand your concern for the elevated blood calcium levels.

It appears to be due to hyperparathyroidism.

The parathyroid glands produce parathyroid hormone, which helps maintain an appropriate balance of calcium in the bloodstream and in tissues that depend on calcium for proper functioning. These glands are about the size of a grain of rice and are located in your neck.

Hyperparathyroidism is an excess of parathyroid hormone in the bloodstream due to overactivity of one or more of the four parathyroid glands. Excess of this hormone results in high levels of calcium in the blood (hypercalcemia) which can cause a variety of health problems.

The range of signs and symptoms include:

•Fragile bones that easily fracture (osteoporosis)
•Kidney stones
•Excessive urination
•Abdominal pain
•Tiring easily or weakness
•Depression or forgetfulness
•Bone and joint pain

Consult an endocrinologist for proper clinical assessment and relevant lab tests to arrive to a diagnosis.

Hope the advice given above would be useful.
Best regards.

I am a 68 year old female with high blood calcium for the last few years. My GP sent me to another doctor, but this other doc doesn t know why I have hypercalcemia either. He has done a 24 hour urine and other blood work, but is puzzled. He says it is not my parathyroid. What would be the next probable cause of this high calcium level in my blood? Thank you.

I am a female of 24 years old with elevated calcium levels. I am currently weaning my 22 month old from breastfeeding. I have just had a blood test measuring my PTH levels and they came back normal with still elevated calcium levels. Could this still be hyperparathyroidism or a more serious problem? They ve asked me to come back in four weeks for a urine test. I ve had no other health problems in the past.
