I am caring for a family member x with mental disability, bipolar and perhaps schizophrenia. He has chronic and excessive belching. Is there a link between the belching and mental disorder because another family member has the same problem. I am wondering if this is a genetic problem with links between the two. male X is not compliant with doctors and nearly caused a fatal accident when we tried to take him to the hospital. He is 32 y.o. and otherwise healthy, although thin, drinks coffee and soda. I am wondering whether we should make a concerted effort to get him to a GI specialist. Thanks, Louise
