1. A device for monitoring movement of a body of a human subject, said device comprising:

  • electronic circuitry including at least one alarm;

    a connector for releasably attaching the device to the subject'"'"'s body in a groin area of said subject'"'"'s body; and

    at least one first proximity sensor,wherein said first proximity sensor is configured and directed to measure a distance between the device and a part of a stomach of the subject that is in a first sensor zone, when the device is attached to the subject'"'"'s body in the groin area;

    and wherein said device includes at least one second proximity sensor that is configured and directed to measure a distance between the device and a part of the stomach of the subject that is in a second sensor zone, when the device is attached to the subject'"'"'s body in the groin area;

    said connector and said first proximity sensor and said second proximity sensor being configured such that the second sensor zone is disposed farther from the connector than the first sensor zone; and

    said circuitry being configured to activate the alarm if a pattern by which the distance measured by at least one of the first proximity sensor and the second proximity sensor varies, changes to a predetermined extent;

    wherein the device is a one-piece unit, and wherein said first proximity sensor and second proximity sensor are configured such that when the device is attached to the subject'"'"'s body, a bottom of the second sensor zone is above the device along the stomach, and a top of the second sensor zone is above a top of the first sensor zone along the stomach.
