How Often Should an Ostomy Bag Be Emptied?

Knowing how often should an ostomy bag be emptied is a vital part of daily stoma care. Emptying ostomy bag at the ideal time helps prevent ostomy bag leaking, protects the surrounding skin from irritation, and ensures you feel comfortable and confident throughout the day.

Quick Answer

UOAA recommends emptying ostomy bag when it is about one-third to one-half full. Waiting until the ostomy pouch becomes a full ostomy bag can add extra weight and pressure on the ostomy wafer, increasing the risk of leaks and skin irritation.

How Often by Ostomy Type

How often you’ll need to empty your ostomy pouch depends on your specific ostomy type and the consistency of your output.

Colostomy

Colostomy output tends to be thicker and more consistent. 
On average, you’ll likely empty your bag 1–3 times daily, largely based on when you eat and how your body processes food.

Ileostomy

Ileostomy output is generally liquid or pasty and occurs more often throughout the day. 
To maintain a secure seal and avoid skin irritation, it is recommended to empty the pouch 4 to 8 times daily, or whenever it becomes one-third full.

Urostomy

Urostomy output is constant and consists of continuous urinary drainage throughout the day
The pouch is usually emptied every 2 to 4 hours, and some users choose to connect a night drainage bag while sleeping.

Signs You Should Empty Your Ostomy Bag

Even if it hasn’t been long since you last emptied your pouch, you should consider doing so if you notice any of the following:

• The ostomy pouch feels heavy or pulls on the ostomy wafer, which often happens with a full ostomy bag.
• Gas buildup causes the bag to balloon.
• Moisture or odor near the seal, which could indicate a slow leak.
• Upcoming activities, such as leaving the house, exercising, or going to bed
