Clinical Trial to Evaluate the Ingested, Space Occupying Hydrogel Capsules for Simple Obesity Treatment

Ingested, Space Occupying hydrogel capsules is indicated to aid in simple obesity treatment with a Body Mass Index (BMI) of 28-40 kg/m2，using under the guidance of a physician.This clinical trial seek to evaluate the efficacy and safety of Ingested, Space Occupying hydrogel capsules for simple obesity treatment.
