My brother-in-law is fed through a g-tube in his stomach. He starts coughing and gagging sometimes almost as soon as we start feeding him but other times half way through or right at the end of the feeding. He has a very pained look on his face when this happens but he also causes the food to flow out of the syringe at times or clogs his tube. Is there anything that can be done to help with this? We have changed his food one time and changed his feeding schedule but so far it has not made a big difference. It seems to be getting worse. Thanks for any advice or suggestions.
