Thank you for replying. We did talk to his Diabetes doctor and he felt that this was not diabetic related. We are seeing a GI doctor right now and she believes it is not GI related but wanted to run a couple more tests to rule other issues out - a Cortisol test and the Hydrogen Breath test. The cortisol test came back normal and the other test is the one we are waiting for the results back. It is a test for overgrowth of bacteria in his gut. It looks like it may be normal (according to the person that performed it). We are awaiting the official results from doctor. We are at a loss of what to do next. He will be fine then he eats something and is nauseous. He either takes showers or baths and he says that helps him feel better. Not sure how the two are connected. My son was diagnosed with Type 1 diabetes thirteen years ago when he was 6 years old. He does take insulin - novolog & lantus. His A1C's have been pretty good - 8.1. He hasn't had any changes in his insulin levels that I think would be causing this. Although when he goes low - it seems to make him really sick. Also if he doesn't eat when he gets hungry he gets nauseous. Any help would be appreciated. Thank you.
