I am getting back ache and stomach cramps after eating food. what does this sound like?

Foods that hurt gut: Fast food is notorious for being low in fiber & generally high in calories from concentrated sweets & fat. Fats delay stomach emptying & promote reflux. Dietary fats also promote release of cck & substance y which alters gut sensitivity, contracts the gallbladder, & prompts the "ileal brake" which in predisposed patients causes bloating & fullness. Choose instead salads, fruits, & whole grains.
