IBS

There are several medical treatments for IBS and many alternative treatments as well.
Probiotics and food elimination diets have not been shown to be clearly effective.
On the other hand, the antibiotic medication rifaximin does have some efficacy for those with IBS diarrhea, and a diet low in certain small carbohydrates, known as FODMAPs, can be helpful.
All of these are low-risk interventions and can be tried as initial treatment options.
