1. An ostomy device comprising:
a nonwoven element having a proximal surface and a distal surface;
an adhesive applied to the proximal surface of the nonwoven element; and
a stoma-receiving opening formed through the nonwoven element;
wherein the nonwoven element comprises a water-soluble component and a releasable material;
wherein, when the ostomy device is applied to a user and stomal output contacts the distal surface of the nonwoven element, the water-soluble component dissolves and releases the releasable material from the nonwoven element to neutralize at least one of enzyme activity and pH of the stomal output.
