Irritable Bowel Syndrome Treatment

Im doing a survey as part of a project and I was wondering what questions I could ask? I have most of the basics like how often do you take them etc…Please help!

When I take antibiotics I get a really upset stomach, which I was told is because the antibiotics also kill the ‘friendly bacteria’ in the gut.
Is it worth taking probiotics to try to replace the friendly bacteria? Or will the antibiotics just kill them too?
Thanks

I hear they work really well. Does anyone know how they help you loose weight? How many do you need to take a day??

I have a condition in my rectum called acute colitis with cryptitis or inflammatory bowel disease. Will prebiotics and probiotics be helpful for this condition? Also, will aloe vera juice help? What alternative treatments are there for inflammatory bowel disease instead of taking prescription drugs?

I’ve read and heard that some antibiotics weaken birth control and prevent it from working properly…well, I was wondering if taking Probiotics along with birth control would inhibitit from working, as well. I really like taking a daily Probiotic because I swear by it. It makes my stomach just feel better and I really don’t want to give that up.
