How to Pronounce Small Intestinal Bacterial Overgrowth

Say it like this: SMAWL in-TES-tih-nal bak-TEER-ee-al OH-ver-growth. The stressed syllable is the first part of each main word—SMAWL, TES, TEER, and OH. Think of it as four separate words spoken together, with emphasis on the first syllable of "Small," "Intestinal," "Bacterial," and "Overgrowth."

SIBO is the abbreviation for Small Intestinal Bacterial Overgrowth, and you pronounce it like "SEE-boh." Medical professionals and patients often use SIBO as a shorthand because the full name is long to say repeatedly.

Many people stress the wrong syllable and say in-tes-TI-nal instead of in-TES-tih-nal. The stress should fall on the second syllable (TES), not the third. Listen carefully to where the emphasis lands when you hear it spoken by a healthcare provider.

Here's how it divides: SMAWL / in-TES-tih-nal / bak-TEER-ee-al / OH-ver-growth. Each section describes a different part of the condition—the size (small), the location (intestinal), what's growing (bacterial), and how much (overgrowth).

Bacterial (bak-TEER-ee-al) means related to bacteria, which are tiny living organisms. The word comes from the Greek word "bakterion," which originally meant "rod" or "staff" because early scientists saw bacteria under microscopes and thought they looked like little rods.

Overgrowth simply means an excessive or abnormal increase in the amount of something. In this case, it refers to bacteria growing too much in a place where they should only exist in small numbers. It's the same "over-" prefix you see in words like "overflow" or "overeat."

Here's an example: "Her doctor explained that she was experiencing symptoms related to Small Intestinal Bacterial Overgrowth, which is why they would need to run specific tests." You might also hear it shortened: "The patient's symptoms were consistent with SIBO."

Intestine (in-TES-tin) is the noun—the actual organ. Intestinal (in-TES-tih-nal) is the adjective form, meaning "relating to the intestines." So in this term, intestinal describes which part of your body the overgrowth is happening in.
