bloody stool

GJ been dealing with blood in the sputum and stool in the past few weeks, and we still don't know what causing it. We already  been in the ER for couple times and still can't figured out whats wrong with my boy. All his lab works are fine and doesn't show any changes in his blood, so I guess we are just dealing with something different here. I made an early appointment with his pediatrician today and they are heading that way right now. Hope everything is well with him. We are just throwing an idea that his G-Tube might be irritating his stomach and needed to be replace. If that the case, it is not a major problem because the pediatric surgeon can do that in few minutes. I hope that's the problem. God be with him!
