Abdominal is an adjective meaning “located in the abdomen” or “relating to the abdomen” — the belly region of your body that holds the stomach, intestines, liver, and other vital organs. Whenever something is described as abdominal, it concerns that part of the body between the chest and the pelvis.

The word is built from the root abdomin- (“abdomen”) plus the ending -al (“relating to”), so it literally means “of the belly.”

How it’s used

You’ll hear “abdominal” attached to many everyday and medical terms. A few common examples:

• abdominal pain → pain felt in the belly area
• abdominal muscles → the muscles of the belly wall (often shortened to “abs”)
• abdominal surgery → an operation performed on organs inside the abdomen
• abdominal cavity → the internal space that contains the abdominal organs
• abdominal cramps → tightening, gripping pains in the belly

Why the word matters

In medicine, being able to label something as “abdominal” immediately narrows down where a problem is. If a doctor notes “abdominal tenderness,” everyone on the care team knows the issue is in the belly rather than the chest, back, or limbs. It’s a simple word that carries precise locational meaning — which is exactly why it appears so often in medical notes, symptom descriptions, and everyday health conversations.

A note on related words

“Abdominal” sits alongside other terms from the same root, such as the noun abdomen itself and the prefixes abdomin- and abdomino-. Recognizing this family of words makes it easier to understand longer medical terms like abdominoplasty (a “tummy tuck”) or abdominopelvic (relating to both the abdomen and pelvis).
