How Often Should a Colostomy Pouch Be Changed?


A colostomy pouch that is used too long may become the cause of discomfort and skin issues. This problem occurs because the excrement from the stoma gets around the wafer, making the skin wet and increasing the risk of infection. 

Thus, when wearing a colostomy bag for a long time becomes inconvenient, the frequency of change should be increased. 

Factors Affecting Pouch Change Frequency

The frequency of changing a colostomy pouch varies depending on several individual factors. Understanding these factors can help determine the optimal schedule for pouch changes.

1. Output Consistency

The consistency and volume of the output from the stoma significantly influence how often the pouch needs to be changed. If the output is more liquid, the pouch may need to be changed more frequently to prevent leakage and skin irritation. On the other hand, individuals with more solid output may find that their pouches last longer.

2. Stoma Location

The location of the stoma on the abdomen also affects the pouch change frequency. Stomas located in areas where there is more body movement, such as near the waistline, may experience more wear and tear on the pouch, necessitating more frequent changes.

3. Skin Sensitivity

Individuals with sensitive skin may need to change their pouches more often to avoid skin irritation and breakdown. Make sure that the skin around the stoma remains healthy. That is vital for overall comfort and well-being of patients.

4. Change in weight. 

Both loss and gain of weight may affect the shape of the stoma, requiring the patient to change the pouch. The stoma should fit the waste output hole properly so that symptoms like leakages would not occur.

Thus, distinguished firm or loose fitting is accompanied with a need to change the bag more frequently.

5. Exercise and daily activities. 

Strenuous sport activities or a gym affect the shape and size of the stoma as it interacts with the waist belt. When people go in for sports every day or once in two or three days, their pouch change requirements differ considerably. Proper management of these pouch requirements may improve their quality of life..

6. Manufacturer Recommendations

Most manufacturers recommend changing colostomy pouches every 5 to 7 days. This guideline is based on average wear times and ensures that the adhesive remains effective and the pouch remains secure. 

However, individual experiences may vary, and it is essential to adjust the schedule based on personal comfort and needs.

Choosing the Right Pouching System

Selecting the appropriate colostomy pouching system is important for effective management. Two main types of pouching systems are One-piece system and two-piece systems. Understanding the differences between these systems can help in making an informed choice.

1. One-Piece Systems

In a one-piece system, the pouch and the skin barrier are combined into a single unit. This system is generally easier to apply and remove, making it a convenient option for many users. It is also less bulky, which can be more comfortable for some individuals.

2. Two-Piece Systems

A two-piece system consists of a separate pouch and skin barrier. The pouch attaches to the skin barrier, allowing for more flexibility. This system enables users to change the pouch without removing the skin barrier, which can be gentler on the skin and more cost-effective in the long run. 

Two-piece systems are also beneficial for individuals who prefer to use different pouches for different activities or times of the day.

Features to Consider

When choosing a colostomy pouch, consider the following features:

  • Odor Resistance: Ensure the pouch has good odor control to maintain discretion and comfort.
  • Ease of Use: Choose a system that is easy to apply, remove, and manage.
  • Skin-Friendliness: Opt for pouches with skin-friendly adhesives and materials to prevent irritation and promote skin health.

Step-by-Step Pouch Change Process

Changing a colostomy pouch involves several steps to ensure hygiene and comfort. Here is a detailed guide to help you through the process:

1. Gather Supplies

Before starting, gather all necessary supplies, including a new pouch, skin barrier wafer, scissors (if needed), stoma measuring guide, adhesive remover wipes, and a clean cloth.

2. Empty the Pouch

Sit comfortably on the toilet and empty the contents of the existing pouch. This step prevents spillage and makes the process cleaner.

3. Remove the Appliance

Gently remove the used appliance by pushing the skin inward rather than pulling the pouch away from the skin. This technique minimizes skin trauma and discomfort.

4. Clean the Skin

Clean the skin around the stoma with warm water, using no scented soaps or alcohol-based products. These products can make the skin irritable. Dry the area up by gently tapping it with a clean dry cloth.

5. Measure the Stoma

Use a stoma measuring guide to measure the size of the stoma. This step ensures that the new skin barrier wafer fits properly and provides a secure seal.

6. Apply the Skin Barrier Wafer

Cut the skin barrier wafer to fit the measured size of the stoma. Remove the backing from the wafer and apply it to the skin, ensuring it adheres well around the stoma.

7. Attach the New Pouch

If using a one-piece system, attach the new pouch directly to the skin barrier. For a two-piece system, connect the pouch to the pre-applied skin barrier. Ensure the pouch is securely in place and comfortable.

Yes, especially if you are using a two-piece system. This flexibility allows you to switch pouches based on your activities and needs without removing the skin barrier.

To prevent leaks, ensure that the skin barrier wafer fits properly around the stoma and that the pouch is securely attached. Regularly check the seal and replace the pouch if it shows signs of wear or damage.


Regularly changing your colostomy pouch is essential for maintaining hygiene, preventing skin irritation, and ensuring comfort. 

While manufacturers usually recommend changing the pouch every 5 to 7 days. Individual factors such as output consistency, stoma location, and skin sensitivity can also influence the frequency. 

Choosing the right pouching system and following a proper change routine can significantly improve your experience and quality of life. Also, proper management and care will help you live confidently and comfortably with a colostomy.
