No lay person seeking medical advice wants to be bombarded with a lot of oddly-spelled and multisyllabic words. And when the concern is your digestive system, you can certainly hear words you've never heard before.
But knowledge is good, and to get started, here are just a few quick definitions of digestive system-related words that often come up. The focus is not so much on anatomy or digestive diseases, but on a few terms that aren't as intimidating as they first seem.
Helicobacter pylori (H. pylori)
You hear it so often because it is a common and pesky stomach bacterium found in populations around the world. H. pylori frequently is to blame for peptic ulcers and gastritis (inflammation of the stomach), as well as certain infections that precede stomach cancer.
H. pylori is detected through testing of the blood, breath or stool. Eradicating the infection sometimes takes a strong combination of antibiotics.
Lower GI Series
Doctors often order this diagnostic test because it can reveal many gastrointestinal conditions (especially in the colon and rectum) and because it is virtually risk-free. Also called a barium enema, a lower GI series involves cleaning out your bowels a day or two ahead of time and then undergoing an outpatient or hospital procedure.
During the procedure, a tube is inserted in your anus and fills your intestine with a special barium liquid. This helps radiologists as they take a series of X-rays of your intestine at various angles.
Food has to move through your digestive system somehow, and the secret of this process lies in peristalsis. While your upper gut squeezes its muscles together to move food downward, the lower gut relaxes itself to receive that food. It's all done in a continuous, wave-like motion that demonstrates the beauty of human anatomy.
