  356. Hypoglycemia
    • Blood sugar levels fall to abnormally low levels.
    • It is caused by excessive insulin administration or excessive production by the pancreas and is often accompanied by headache, malaise (weakness), tremors, hunger, and anxiety.
    • If left untreated, it can lead to coma and death
  357. Hyperparathyroidism
    • The excessive production of PTH by the parathyroid glands
    • Usually caused by a tumor, it results in excessive calcium levels in the blood (hypercalcemia)
