Why wrap Should Not Be Waterproof: A Practical Guide for Ostomy Patients

August 24, 2025

Ostomy belts are an essential accessory for many ostomates. Their main purpose is to provide support, comfort, and safety, promoting mobility and helping to prevent complications such as a peristomal hernia.
But while it might seem like a good thing that these belts are waterproof, the reality is quite the opposite. In this article, we explain Why an wrap shouldn't be waterproof and what risks can be avoided by choosing a breathable fabric.

1. The importance of perspiration in the peristomal skin

The skin around the stoma is particularly delicate and is in constant contact with the collection device. If the wrap waterproof, natural perspiration is blocked, causing heat and sweat to build up.
This can cause:

Skin maceration.
Irritation and dermatitis.
Increased risk of infection.

Breathable dressings help keep the skin dry and healthy, preventing complications that can affect both patient comfort and the adhesion of the devices.

2. Issues with trapped air and buoyancy in water

A lesser-known but very important aspect is what happens when a person with an ostomy goes into the water wearing a wrap .
Any air pockets trapped inside will tend to rise to the surface through the difference in density between air and water, generating lift.
This translates to:

Discomfort when swimming or moving.
Movement of the swimsuit or the wrap itself.
Risk of pressure or traction in the stoma area.

Therefore, a wrap is not only impractical but also unsafe for water activities.

3. Safety and comfort as top priorities

The goal of a good wrap is to give ostomates confidence in their daily lives. To achieve this, the design should focus on:

Stretchy, breathable fabrics that ensure comfort.
Proper support without compressing the stoma.
Water-resistant but not waterproof materials that allow moisture and trapped air to escape.

Conclusion

Although it may seem like a good idea, an wrap should not be waterproof. Skin breathability and the release of trapped air are essential for preventing irritation, improving comfort, and ensuring safety—both in daily life and during water activities.

👉 Practical tip: When choosing your wrap , always look for breathable styles designed specifically for ostomates. This will give you greater freedom of movement, a lower risk of complications, and a better quality of life.
