    Zollinger-Ellison syndrome

    Endocrine glands release hormones (chemical messengers) into the bloodstream to be transported to various organs and tissues throughout the body. For instance, the pancreas secretes insulin, which allows the body to regulate levels of sugar in the blood. The thyroid gets instructions from the pituitary to secrete hormones which determine the pace of chemical activity in the body (the more hormone in the bloodstream, the faster the chemical activity; the less hormone, the slower the activity).

    Zollinger-Ellison syndrome is a condition in which there is increased production of the hormone gastrin. Usually, a small tumor (gastrinoma) in the pancreas or small intestine produces the high levels of gastrin in the blood.
