A method for treatment of obesity involves implantation of bulking devices within the upper esophageal sphincter (UES) to inhibit swallowing, thereby limiting food intake and treating obesity. One or more bulking devices are implanted within or near the UES to create a partial obstruction, partially impair UES muscle function, or both. The bulking devices make swallowing difficult, limiting the rate of food intake by a patient, and discouraging the patient from quickly consuming an excessive amount of food at one time.
