Convex ostomy pouching systems can quite helpful in the prevention of common peristomal issues such as leakage. Unlike the barriers with a flat adhesive back, convex barriers have a protruded back that gives the entire barrier portion an outgoing shape. Manufacturers have created this protrusion to use against the peristomal skin, which, in turn, forms an even tighter seal to prevent leakage in the best way possible.

You can benefit considerably from convexity in ostomy supplies if you want to achieve optimum stoma seal. Convexity in ostomy supplies can be beneficial for the people who have stomas of uneven shape, unusual size, or irregularities in the peristomal skin area. In many cases, the stoma sits below the skin level. Resultingly, the skin surrounding the stoma becomes uneven that can lead to the leakage of stomal output after the application of the skin barrier. The convex pouching system is an answer to such a problem as it applies an appropriate amount of pressure on the peristomal skin to prompt the stoma’s necessary protrusion. And since the barrier secures the entire peristomal skin area, it forms a tighter seal that prevents the leakage of stomal output in an ideal way.

The primary purpose of a convex ostomy pouching system is to prevent leakage from an ostomy whose stoma doesn’t protrude appropriately. It means that appropriate protrusion of a stoma is necessary for a normal skin barrier to work. A convex ostomy system pushes the skin surrounding the stoma to encourage its protrusion up to a level where its base becomes accessible to the edges of the flange’s opening. Once the barrier properly settles on the skin, it forms a leak-proof seal, which is the primary purpose of a convex pouching system.

There are several cases in which doctors may prescribe the use of a convex ostomy pouching system. Such cases mainly include frequent ostomy leaks, retracted stoma, telescoping stoma, higher stomal output, stoma at peristomal skin level, loop ostomy, creases in the peristomal skin, and scars in the skin around the stoma.

There only a specific set of reasons that make an ostomate qualify for the convex pouching system use. It means that you need to avoid using these systems on your own without the recommendation from your doctor. Keep in mind that a convex system might result in injuring your stoma if normal systems work well for you. Moreover, there are several conditions and symptoms in which doctors recommend against using a convex system.
