Caring for your skin and changing your bag are important parts of your colostomy care. Here are some helpful instructions:
The skin on your stoma, or opening in the abdomen, will look redder than the rest of the skin around it. It’s even normal for it to bleed for a few minutes occasionally because the skin is so delicate, but it shouldn’t be painful or itchy. Sometimes the output from your colostomy makes the skin of your stoma sore. To keep the skin of your stoma as healthy as possible:
Clean your stoma with water. You don’t need to use soap or sterile supplies. Be sure to dry the stoma completely.
Be gentle. Having a colostomy doesn’t need to stop you from doing your daily activities—including exercise. However, when you’re changing your colostomy bag, be gentle when pulling the pouch away from the skin. The skin of your stoma and around it will always be delicate.
Use the appropriately sized supplies. Both the pouch and the skin barrier opening should be the appropriate size for your stoma. If the opening is too small, it may constrict the stoma, and if the opening is too big, the bag may leak. Your stoma size may change as it heals, or it may change for other reasons. Ask your care team whether you need help finding supplies that are the appropriate size for you.
Change your pouch regularly. How often you’ll need to change your pouch depends on the kind of system you use. Make sure you know how often to change it.
Watch for allergies. You may develop an allergy to the materials in your supplies at any time, even after having your colostomy for years. If you have an allergic reaction to the pouch, adhesive or tape, you may notice irritated or itchy skin. If you do notice irritation, try changing brands or using a pouch cover to separate the pouch and your skin.
Watch for infection. Your skin may also be itchy and irritated due to an infection. If you notice wet, itchy, bumpy or painful skin on or near your stoma, call your care team right away. These may be signs of an infection.
Irrigating your colostomy is a personal choice. When you irrigate your colostomy, you run water through your stoma and into your colon. Doing this at the same time every day may help you develop a more predictable routine for bowel movements that your body will get used to.
Many people with colostomies used to irrigate them to manage their bowel movements, but colostomy supplies have improved in recent years, so some now opt not to irrigate.
Ask your care team for more information, and if you choose to irrigate, ask them for specific instructions that may help you get into a routine.
Irrigation is only used for descending or sigmoid colostomies, not transverse colostomies.
The right time to irrigate tends to be after eating or having a hot beverage. It may work well to choose a time when you typically used to have bowel movements before your colostomy. The process may take about an hour, so choose a time when you’ll have access to a bathroom for the whole time.
To irrigate your colostomy:
With time and practice, you’ll notice your body’s signs that the process is done. The stoma may look inactive, or you may notice some gas that signals that your body is done with the irrigation process. When all the stool is out, remove the irrigation sleeve, reattach your regular pouch, rinse your irrigation supplies and hang them to dry out.
Aside from the light cramping, you shouldn’t feel pain, cramps or nausea. Tell your care team if you do. Discomfort may mean that there’s too much water or that it’s too cold.
Remember that your care team will walk you through exactly how you should irrigate your colostomy if you choose to do so. Learning to irrigate is probably a new skill for you, so be sure to ask your care team any questions you have along the way.
To prevent problems like bulging or leaking, empty your colostomy bag when it’s about a third to half full. Over time, you’ll be able to tell how often you’ll need to do this. To empty your colostomy bag:
Make a planned routine for changing your colostomy bag. Different pouch systems need to be changed more often than others. Some should be changed daily, while others may only need to be changed once a week.
Your care team will let you know how to change your type of colostomy bag. Refer to these instructions as general guidance:
Life with a colostomy bag can be a lot to get used to. As the weeks go by after your colostomy, you’ll get more comfortable with your colostomy bag and the ways to manage it. You’ll start learning your body’s new habits and get into the swing of life with this new tool. Even after you’re well versed in managing life with a colostomy bag, it’s a good idea to have your supplies on you at all times.
The food you eat will affect the stool and gas you produce. It may determine whether your stool is more liquid or solid. How much you eat and when you eat may also affect the output in your pouch.
You may need to pay special attention to how your body reacts to the foods you eat. Over time, you’ll get used to the new rhythms of your digestion. You may find that it’s helpful to plan your meals in advance and eat at certain times of the day.
Just as before your colostomy, you may experience gas, diarrhea or constipation. Keeping a record of the food you eat and how your body processes it may help you figure out the foods that help you feel your best.
Just like life before your colostomy, your stool will likely still have an odor. This is due to the bacteria that work to digest your food, and it’s normal. The good news is that colostomy pouches trap bad smells with an odor-barrier film. You may smell an odor when emptying the pouch, but you shouldn’t smell one otherwise.
Certain brands of pouching systems may also offer the following odor-eliminating options to give you extra peace of mind:
Some foods cause more odorous stool than others. You may be able to decrease the odor of your stool by limiting certain foods, such as:
You can shower and bathe with your colostomy bag, and you don’t need to remove it. In fact, your care team may recommend that you leave it in place while you shower or take a bath.
While soap isn’t bad for the skin on or around your stoma, using it may loosen the skin barrier or make it less likely to stick. So only use water to clean around your stoma, and rinse your skin well if you do use soap.
Likewise, you can leave your colostomy bag attached if you swim. If you prefer, you can buy swimwear that covers your colostomy bag.
