I will try my best to answer your query there are many issues here that you need to see first, does he have gastroenteritis? if he does you need to get him to a hospital as soon as possible so he can be initiated on antibioitcs. second, are his sugars well controlled? if they are high, he may be in a state called as diabetic ketoacidosis, where sugars are really high and patient has abdominal discomfort and is triggered by infections and dehydration third, get an ecg for him, and a stress echo would be better still. the reason is simple. he is a diabetic and may be developing coronary artery disease. and this needs to be ruled out. the abdominal discomfort may be atypical sign of CAD and loosemotions are known in some patients of CAD. if only water is coming in stools, why is he given laxatives? ask your dr that. suggest cbc, fbs, ppbs, ech, chest x ray, and kft as soon as possible I hope this helps you.
