I have gerd and like symptoms of ibs, but there are so many do's and don't (what one can eat, and cannot) online webs are very contradicting, any adv?

GERD/IBS: For gastritis reduce alcohol, caffeine and smoking for ibs increase fiber, water and consider relaxation techniques for both.

Nutritionist: May make sense to see a nutritionist to help create a specific diet plan. Classic things to avoid include caffeine, nicotine, licorice, peppermint, chocolate, spicy foods, citrus. Avoid late night meals or lying down within 2 -3 hours after eating. Portion size has a major effect, try eating smaller portions.
