Abstract

Methods for the treatment of obesity, overweight, compulsive overeating, emotional overeating, binge eating, bulimia and anorexia comprises the steps of monitoring physiological parameters in the esophageal and/or gastrointestinal tract which are associated with gastric relaxation, gastric filling, gastric contractions, gastric secretions, and gastric emptying. The measurement are transmitted either directly to a receiver or via radiotelemetry to a receiver. The receiver has a data processor associated therewith, and the data processor produces audio and/or visual feedback for the person under treatment to hear and/or see. This feedback is used for purposes of teaching behavior modification and other psychotherapeutic purposes. In the most simple form of the invention, a warning sound is generated by the data processor indicating when sufficient food has been ingested. This warning can be generated by the monitoring apparatus much sooner than the biological signal of fullness transmitted by the stomach to the brain of the person. The person can thereby discontinue eating before otherwise becoming unconsciously too full.

Claims

1. A method for the treatment of obesity, overweight, compulsive overeating, emotional overeating, binge eating, bulimia, anorexia and hypertension associated with weight loss, said method comprising

measuring gastrointestinal sound in a person under treatment while the person is eating or drinking;

transmitting the measured sound to a data processor which produces an auditory analog signal;

amplifying the auditory analog signal; and

reproducing the auditory analog signal for the person under treatment to hear, thus giving the person under treatment a clear, audible feedback of gastrointestinal sound.

2. A method in accordance with claim 1, wherein the data processor produces auditory analog signals of variable tones or pitches representing different levels of gastrointestinal sound indicating the presence and rate of gastric filling.

3. A method in accordance with claim 1, wherein the gastrointestinal sound is measured using a radiotelemetry capsule which is placed in the stomach of the person under treatment, with the radiotelemetry capsule comprising a sound sensitive transducer and means for emitting a low power, frequency modulated, radio signal corresponding to gastric sound, and further wherein a receiver is placed near the stomach on the exterior of the body of the person under treatment, and the receiver receives the radio signal from the radiotelemetry capsule and forwards the radio signal on to said data processor.

4. A method in accordance with claim 3, wherein the radiotelemetry capsule is constrained to the stomach of the person under treatment.

5. A method in accordance with claim 3, wherein the data processor in combination with display means produces a visual display of animations or cartoons from the measured sounds, with the animations or cartoons representing gastric filling and function during eating and drinking.

6. A method in accordance with claim 3, wherein the data processor also produces a signal which is displayed on a visual display means such as a meter or video monitor.

7. A method in accordance with claim 1, wherein the data processor also produces a signal which is displayed on a visual display means such as a meter or video monitor.

8. A method in accordance with claim 1, wherein the data processor in combination with display means produces a visual display of animations or cartoons from the measured sounds, with the animations or cartoons representing gastric filling and function during eating and drinking.

9. A method in accordance with claim 1, wherein the data processor produces auditory analog signals of variable tones or pitches representing the total volume of sound produced and the total volume of gastric filling from ingestion over a particular period of time.

10. A method in accordance with claim 1, wherein the data processor comprises a computer and a microphone is placed against the body of the person under treatment to monitor gastric sounds.

11. A method in accordance with claim 1, wherein the data processor comprises a computer and a microphone is placed against the esophageal tract of the person under treatment to monitor swallowing or chewing sounds and the sounds of food or liquid as it passes from the mouth through the esophagus and into the stomach.

12. A method for the treatment of obesity, overweight, compulsive overeating, emotional overeating, binge eating, bulimia, anorexia and hypertension comprising

measuring gastrointestinal pressure in a person under treatment while eating or drinking;

transmitting the measured pressure to a data processor which produces an auditory analog signal; and

amplifying the auditory analog signal and reproducing the auditory analog signal for the person under treatment to hear giving the person under treatment a clear audible feedback of gastrointestinal pressure.

13. A method in accordance with claim 12, wherein the data processor produces auditory analog signals of variable tones or pitches representing different levels of gastrointestinal pressure indicating the presence and rate of gastric filling.

14. A method in accordance with claim 12, wherein the data processor in combination with display means produces a visual display of animations or cartoons from the measured sounds, with the animations or cartoons representing gastric filling and function during eating and drinking.

15. A method in accordance with claim 12, wherein the data processor also produces a signal which is displayed on a visual display means such as a meter or video monitor.

16. A method in accordance with claim 12, wherein the gastrointestinal pressure is measured using a radiotelemetry capsule which is placed in the stomach of the person under treatment, with the radiotelemetry capsule comprising a pressure sensitive transducer and means for emitting a low power, frequency modulated, radio signal corresponding to gastric pressure, and further wherein a receiver is placed near the stomach on the exterior of the body of the person under treatment, and the receiver receives the radio signal from the radiotelemetry capsule and forwards the radio signal on to said data processor.

17. A method in accordance with claim 16, wherein the radiotelemetry capsule is constrained to the stomach of the person under treatment.

18. A method in accordance with claim 16, wherein the data processor in combination with display means produces a visual display of animations or cartoons from the measured sounds, with the animations or cartoons representing gastric filling and function during eating and drinking.

19. A method in accordance with claim 16, wherein the data processor also produces a signal which is displayed on a visual display means such as a meter or video monitor.

20. A method in accordance with claim 16, wherein the data processor comprises a computer, and the method further comprises placing a pressure sensing element in the stomach of the person under treatment to monitor gastric pressure.
