How to Change a Colostomy Bag & Other Ostomy Tips

Most ostomy patients worry about life after an ostomy. What will it be like? Will I have to change a colostomy bag in public? How do you manage life with a bag attached to your belly?

Whether your ostomy is temporary or permanent, there’s a lot to learn. But within a few weeks, most patients are pros.

After an ostomy, you can do everything you did before. You just have to learn some of the basics covered here. "You should be able to live the same life," says colorectal surgeon Charles Friel, MD.

Stomas, and Pouches, and Wafers, Oh, My!

So, you have a stoma — that raised, pinkish-reddish opening on your belly that connects part of your colon to the outside world. A sturdy colostomy bag hugs your belly. It’ll hold poop and fluids that come through the stoma until you can get to a toilet.

Common pouching systems have a flat or curved baseplate called a wafer. This firm surface connects to the pouch and sticks to your belly. You can get pouch covers or belts for extra support.

At UVA Health, we provide a support team and a class to get you started. It’s OK if it still feels a little weird. But as Friel notes, most people tell him, "It's not as bad as I thought it would be."

Who Needs to Know?

Tell your healthcare providers and pharmacists about your ostomy. It affects treatment plans and changes how your body absorbs medicines and nutrients. Your providers may recommend diet tweaks or options like time-release capsules.

After that — beyond your spouse and family — it’s up to you. You may tell a few trusted friends. Most pouches are odor-free and invisible to others.

You can tell curiosity-seekers you had abdominal surgery, without details. You might choose to join friendly support groups. Some people reach out to encourage and educate others in person or online. You decide what you’re comfortable sharing.

A Good Fit   

Newbies know your stoma-bump can poke through a pouch-opening called a wafer. Of course, pouching-styles vary. And some stomas shrink as they heal. If yours does, make an appointment with your ostomy nurse for a refitting.

You shouldn’t need another refit unless you gain or lose weight. Tell your providers if you have changes or challenges, such as discomfort or leaking.

Emptying Your Pouch

Pouch-emptying steps depend on your pouching system and type of ostomy. Follow your nurse’s instructions closely. Ask questions until you’re comfortable with your routine.  

After a colostomy, you may have one or more bowel movements a day, with some fluids. Some ostomy types have high liquid-waste outputs. You empty them more often.

When properly fitted, ostomy pouches prevent leaks. Even so, it’s best to prevent over-filling. Emptying more often also helps prevent skin irritation or leaking.

Wash your hands with soap and water. Dry them well before you empty the pouch. If you have a bag with a clamp on the bottom, you can sit on or near a toilet, or stand. Remove the clamp and slowly drain the pouch into the toilet.

Some bags detach and have an opening at the top. Others have a rolled or folded “tail” with adhesive. Once you open the bag, slowly empty fluids and waste into the toilet.

Clean the bag with wipes, toilet paper, or paper towels. Then, replace the clamp or close it, using adhesive or other types of closures. Toss or flush disposables. Wash your hands thoroughly with soap and water.

How to Change a Colostomy Bag

Most people change an ostomy bag every 3 to 5 days or longer, depending on the pouching system and type of ostomy. Organize supplies in ways that work for you. Every pouching system is different. Your care team will show you how yours works.  

Gather Supplies

Typical supplies include:

Change Your Pouch

Use soap and scrub up.

When the Doctor Becomes the Patient

He's treated people with colorectal cancer for years. Then it was his turn.

Examine & Treat the Area

Your stoma should be pink or red and moist. A little bleeding is OK. Tell your provider if you see black, blue, or purple skin; a sore; or a rash. Your care team will tell you when to contact your provider. Your nurse will teach you about pouching systems and where to find them.

If it’s a one-piece pouch:

Ostomy Clothing 

You can keep most of your favorite threads. Unless you wear clingy tops, a pouch isn’t noticeable. Some people prefer baggy clothes or clothes with a higher waistband. For added support, you can wear stretchy underwear that holds the pouch in. Lined swimsuits also conceal a pouch (yes, you can still go swimming with an ostomy bag!).

You can shop for post-ostomy underwear, swimwear, and sportswear. They’ll provide extra support and a slimming appearance.
