1. A method of causing weight loss in obese humans by occupying a segment of the stomach volume using an inflated bladder, said method comprising the steps of:

  • (a) measuring the volume and location of the stomach including the fundus by radiological techniques,(b) selecting a bladder contoured in size and shape to substantially occupy the fundus or the body of the stomach measurement,(c) introducing by percutaneous endscopic techniques a percutaneous endoscopic gastrostomy (P.E.G.) tube to establish access from the outside to the body of the stomach through the abdominal wall,(d) inserting said bladder through said percutaneous endoscopic gastrostomy tube into the stomach so the size and shape of said bladder, cooperating with the position of placement of said gastrostomy tube, maintains said bladder in the upper part of the stomach including the fundus, and(e) filling and emptying said bladder with fluid repeatedly over time through a filling tube that extends through said gastrostomy tube, in the manner that said bladder when filled occupies a large portion of said stomach to cause a feeling of satiety, thereby to achieve decreased consumption of food by a patient, and said emptying of said bladder provides periods of reduced trauma to the stomach to promote the patient'"'"'s health and feeling of well being, said bladder capable of being withdrawn from said stomach through said P.E. G. tube to enable inspection and replacement and to enable ready access to the lumen of the stomach through the abdominal wall.
