1. A method for treating a subject having a stomach with a stomach wall surrounding a cavity of the stomach, the method comprising:
- implanting electronic circuitry within the subject;
supporting a temperature sensor within the cavity of the stomach so as to measure a temperature within the cavity;
electrically coupling a stimulating electrode to the wall of stomach;
operatively coupling the circuitry to the temperature sensor;
operatively coupling the circuitry to the stimulating electrode;
sensing the temperature within the cavity of the stomach with the temperature sensor;
determining, using the circuitry and in response to the sensed temperature, a rate of change of the temperature within the cavity of the stomach;
identifying, using the circuitry and in response to the rate of change of the temperature within the cavity of the stomach, an ingestion of material by the subject; and
stimulating the stomach by energizing the electrode using the circuitry in response to the identified ingestion of material by the subject.

Abstract
A responsive gastrointestinal stimulation device is provided where one or more sensors sense data corresponding to a subject or the gastrointestinal tract of a subject and responds to sensing the data by stimulating, adjusting stimulation, or stopping stimulation of the gastrointestinal tract. A stimulation device is also provided to stimulate the gastrointestinal tract to produce a sensation of satiety or to control hunger or food consumption.
