When my 3-1/2 year old daughter gets gluttened, she has projectile vomit (she throws up with a lot of force) and she is constipated. In fact, she tries to hold the poop in since it is so hard and hurts her to come out. She refuses to eat again until she feels better. My other daughter gets very grumpy and has diarrhea when she is gluttened. Have you considered...
