The present invention discloses a capsule endoscope with specific gravity control. The capsule endoscope comprises a housing to enclose various components, an inflatable device attached to a first longitudinal end of the capsule unit and an enteric coated shell attached to the first longitudinal end of the capsule unit to enclose the inflatable device between the enteric coated shell and the capsule unit. The various components include a camera sub-system for capturing image frames. The inflatable device comprises an inflatable membrane and an effervescent formulation inside the inflatable membrane. The enteric coated shell fits tightly onto the first longitudinal end of the capsule unit to prevent body liquid from leaking into a space between the enteric coated shell and the capsule unit when the capsule unit travels in human gastrointestinal tract after being swallowed.

An endoscopy capsule having an image collecting capacity includes a deformable member configured to inflate when exposed to body liquid. The deformable member includes an effervescent material. When the effervescent reacts with water the resulting Carbon-Dioxide gas reduces the specific gravity of the endoscopy capsule. The capsule is contained within a shell or dome when swallowed. The shell or dome is configured dissolve in either a low or high pH environment.
