Intestinal information estimation system

Abstract

Intestinal information of a subject is accurately estimated from a component contained in a gas generated from feces of the subject. Included are a detector configured to detect a predetermined component from a gas released from feces of a subject and output a detection signal depending on a concentration of the predetermined component and an estimator configured to input the detection signal or the concentration of the predetermined component corresponding to the detection signal to a prediction model and estimate information regarding an amount and/or an existence ratio of short-chain fatty acid-producing bacteria and/or a metabolite contained in the feces of the subject. The predetermined component is at least one selected from the group consisting of methyl mercaptan, hydrogen sulfide, hydrogen, and carbon dioxide.

Dependencies are inferred from the claim text.
