This topic is about a person who recently had a colostomy and is experiencing an unusual and strong rotten-egg or vomit-like odor from their output. They are concerned because this type of smell is more commonly associated with ileostomies, and they are worried about potential complications like an infection. They are also hoping to avoid a hospital visit during the holiday season.

Here are some helpful insights and advice:

1. If you notice a strange odor, it might be best to "wait and see" how the next few outputs look and smell. Odd odors can happen occasionally and may not indicate a serious issue.

2. Foods that are high in sulfur, such as garlic, eggs, dairy, and meats, can often cause a rotten-egg smell. You might try reducing or spacing out garlic-rich foods to see if it helps.

3. Keep an eye out for other warning signs like fever, chills, pain, visible blood, or feeling light-headed. If you notice any of these, it's important to contact a doctor or visit the emergency room.

4. Internal bleeding usually has a very foul odor and is accompanied by visible blood in the pouch, unless it's hidden by iron supplements. It can also cause light-headedness. If you see blood, seek medical attention immediately.

5. Having looser output can be normal in the first few months as your colon adjusts. However, very loose or diarrheal output can have a stronger smell.

6. If you're still worried, don't hesitate to call your stoma nurse for reassurance and an assessment, especially if you're concerned about a blockage or infection.

7. For odor control, you can use deodorizer drops for your colostomy pouch. Products like Hollister M9 Odor Eliminator are available online, and you can add a few drops after each emptying.

8. Some people find success in eating what they like and using deodorizer drops, while others choose to limit foods that trigger odors, like garlic bread, and enjoy them occasionally.

9. Remember that it's normal for the odor to vary significantly from one meal to the next. The amount of the trigger food and what you eat it with can both affect the smell.
