Polycythemia vera is a rare blood disorder in which there is an increase in all blood cells, particularly red blood cells. The increase in blood cells makes the blood thicker. This can lead to strokes or tissue and organ damage.
Primary hyperparathyroidism is a metabolic disorder in which one or more of the parathyroid glands produces too much parathyroid hormone. This can result in a loss of bone tissue. A job of the parathyroid hormone is to keep blood calcium levels from going too low. This is done by releasing calcium from bones. The hormone also conserves calcium that would be excreted by the kidneys, and increases how much calcium is absorbed from food. When the hormone overacts, the result is a rise in the blood calcium level. Too much parathyroid hormone causes too much calcium to be released from bone.

|Pheochromocytoma: An Adrenal Gland Tumor
A pheochromocytoma is a rare type of tumor. It grows in the middle of an adrenal gland. Your body has 2 adrenal glands. They are found on top of each kidney. Each layer of these glands makes different hormones. The middle part of the adrenal glands makes epinephrine and norepinephrine. These hormones help keep your heart rate and blood pressure normal. A pheochromocytoma causes the adrenal glands to make too much of these hormones.
