1. An intragastric stent comprising a substantially cylindrical thin-walled shell sized for snug fitting in a duodenum adjacent to the pylorus without extending into the stomach, the shell including a peripheral wall impervious to digestive juices such that, when deployed in the duodenum, uptake of food through the stent is lessened or inhibited, the shell being bioabsorbable so that the shell will pass from the duodenum without surgical intervention after an approximately predetermined period of 3 months to 2 years.
