What Are Absorbent Ileostomy Gel Packets? Absorbent Ileostomy Gel Packs turn liquid output into a uniform gel. The small packets dissolve so you don't have to open them up, just place the packet inside your clean ostomy pouch. When the gel pack comes into contact with liquid output, it will cause the output to form into a gel. This makes the bag easier to drain and it is helps keep the output at the bottom of your bag. When your output is sloshing around inside your bag it can cause leaks because it will often clog up your filter. Absorbent gel packs combat this by dissolving quickly and forming a uniform consistency.
