This topic is about dealing with gas-related bloating and discomfort after having an ostomy, especially when it comes to eating certain foods. The person who started the discussion is experiencing stomach bloating and painful gas after meals and is looking for advice on how to manage these symptoms, particularly when it comes to dairy products. Here are some helpful insights and advice shared by others:

1. Lactose-management:
- Many people find success using Lactaid tablets with dairy products or opting for Lactaid brand lactose-free milk, which tastes like whole milk and lasts longer.
- Taking chewable fast-acting Lactaid before consuming yogurt or milkshakes can help reduce gas, but it's important to monitor your own body's response as tolerance can vary.

2. Gas-relief medications:
- Gas-X, which contains simethicone, is effective for many individuals both before and after ostomy surgery.
- Some people use Beano alongside Lactaid to help reduce gas from complex carbohydrates.

3. Food-specific tips:
- Bananas are often a culprit for bloating; reducing the portion to half a banana or avoiding them altogether can be beneficial.
- Milkshakes and other rich dairy foods are common triggers for gas; trying to eliminate them from your diet might help.
- Sticking to a consistent and less varied diet can assist in identifying which foods cause issues.

4. General coping strategies:
- Consider a trial-and-error elimination diet by removing suspected problem foods, like dairy, for a period and then reintroducing them to see if they cause symptoms.
- Learning from the experiences of others who have had similar issues can be more practical than general medical advice. Engaging in forums can provide a variety of tried-and-true solutions.
