How Long Does an Ostomy Bag Stay On? A Patient & Family Guide

What is “Wear Time” for an Ostomy Bag?

When someone has an ostomy (such as a colostomy or ileostomy), they use a pouching system to collect waste from a surgically created stoma. The term wear time refers to how many days you keep that system in place before replacing it.

According to the University of Chicago Medicine, the pouching system should be emptied when it is about one-third full and changed every three to four days.

As Hollister Incorporated explains, most people change their ostomy pouching system every three to four days, although actual wear time can vary based on lifestyle, stoma type, and skin condition.

What Factors Affect How Long the Bag Can Stay On?

Several variables influence wear time:

Stoma type and output consistency: According to My Ostomy Care, individuals with an ileostomy (more liquid output) may need to change their appliance more often than those with a colostomy (more formed stool).

Skin and body shape: Per Hollister, sweat, oily skin, or uneven skin surfaces can affect how long the barrier adheres securely.

Output amount and frequency: Byram Healthcare notes that letting the pouch overfill can lead to leaks and decreased wear time.

Time since surgery: Early post-op changes in the abdomen can affect appliance fit, as detailed by The Gastrointestinal Society (BadGut.org).

Activity level and climate: As per Hollister, physical activity or hot weather may reduce wear time due to increased sweat and movement.

General Guidelines for Changing Your Ostomy Bag

Most ostomy care sources suggest not exceeding 7 days of wear time.  (My Ostomy Care)

For most users, changing the appliance every 3 to 5 days works well. (Byram Healthcare)

For closed pouches, daily replacement may be needed. This is especially common with colostomies producing solid stool, as discussed by Bladder & Bowel UK. 

Empty the pouch when about one-third full to avoid excess weight on the barrier. (UChicago Medicine)

Early leakage or skin irritation are signs it’s time for a change, even if it's sooner than scheduled. (My Ostomy Care)

When Should You Change Sooner Than Scheduled?

Replace your pouching system immediately if you experience:

Lifting or loosening of the adhesive

Signs of leakage or odor

Red, irritated, or painful skin around the stoma

Major change in stool consistency

Heavy sweating or physical activity compromising the seal

Tips to Maximize Wear Time and Protect Your Skin

Ensure a snug fit around the stoma

Thoroughly clean and dry the skin before application

Use appropriate barriers (flat, convex, rings, paste, etc.)

Don’t overfill the pouch

Consult a stoma nurse if wear time is highly variable or below 2 days regularly
