As soon as i eat i need to use the rest room, docs i went to said it's ibs. what do i have to do to get rid of it.i have it for years & im tired of it?

Dietary changes: There are many triggers for ibs, but some people find that dietary changes can make a big difference. Maybe try the fodmap diet and see if it helps? http://stanfordhospital.org/digestivehealth/nutrition/dh-low-fodmap-diet-handout.pdf.

Sure it's IBS?: I understand your frustration! but, perhaps you can help us help you by telling us what tests have been done ; what medications have been tried over the years of evaluation. No sense having us recommend to you studies you've already accomplished, treatments that you've already failed, or offer possible alternative diagnoses that have already been considered and ruled out.
