MONITORING, ANALYSIS, AND REGULATION OF EATING HABITS

摘要

Gastric apparatus (18) is provided, including one or more sensors (70, 72, 74), adapted to generate respective sensor signals responsive to activity of a gastrointestinal tract of a subject. A control unit (90) is adapted to receive and analyze the sensor signals and to determine that an eating event has occurred, responsive to at least one of the sensor signals and a threshold. The control unit identifies an aspect of at least one of the sensor signals deriving from rhythmic activity of the gastrointestinal tract that is not indicative of current eating by the subject, and modifies the threshold responsive to the aspect of the signals that derives from activity that is not indicative of current eating. For some applications, the control unit is adapted to modify the threshold if the aspect is indicative of a migrating motor complex (MMC). Other embodiments are also described.
