The presently disclosed subject matter is directed to an ostomy pouch comprising at least one absorbent material housed within the interior of the pouch. Specifically, the absorbent materials are contained within a sachet that includes at least one of the following: a frangible seal, a porous film, or a fluid-permeable film. In use, as fluid enters the interior of the ostomy pouch and contacts the sachet, the porous film and/or the frangible seal weakens to allow fluid to enter the sachet and contact the absorbent material housed within. Alternatively or in addition, in embodiments wherein the sachet includes a fluid-permeable film, fluid directly enters the interior of the sachet. As a result, the absorbent material expands and ruptures the frangible seal and/or the sachet, thereby releasing the absorbent material into the interior of the pouch for full absorption of the fluid.
