This topic is about someone who has an ileostomy and experienced severe gas and pain after eating pizza. They are trying to figure out what might be causing these symptoms and are seeking advice from others who might have had similar experiences. Here are some helpful insights and advice shared by others:

1. Food sensitivities can develop unexpectedly. It might be best to avoid pizza and any other foods you suspect until your symptoms improve.

2. It could be a temporary gastrointestinal bug. Try eating bland foods for a while, and then slowly reintroduce other foods in small amounts to see if you can identify any triggers.

3. Consider the possibility of a partial blockage. Ingredients like nuts in baklava or hard-to-digest pizza toppings could be the cause. If the pain returns, stop eating solid foods, switch to liquids, keep an eye on your stoma output, and seek medical help if things get worse.

4. For gas relief, you might try:
- Drinking carbonated beverages like Coke Zero, ginger ale, or 7-Up to help induce burping.
- Gentle abdominal massage, walking, rotating your body, and deep belly breathing.

5. Heavy, doughy foods like pizza crust and pasta can thicken your output and cause discomfort. Consider limiting portion sizes or avoiding them altogether.

6. Thick, chewy mozzarella cheese might not break down well. You could try using thinner cheese or exploring different pizza styles.

7. If you're over 30, lactose intolerance might be developing. Pay attention to how you react to other dairy products.

8. Norovirus is going around in some areas, and its symptoms can resemble food intolerance.

9. Some over-the-counter aids that might help include:
- CVS Health Intestinal Defense Peppermint Oil Softgels
- IBgard (peppermint oil capsules)
- Use Gas-X cautiously, and stop if it doesn't help.

10. Don't endure severe pain for too long. If your symptoms persist or worsen, it's important to contact a healthcare professional.
