I have had severe gas and bloating at night for a few weeks and then ended up with what I can only assume is the stomach flu. Diarhea, nausea, vomiting, fever of 102. Now I have soft, bright yellow stool throughout the day and severe gas and bloating at night, and a constant burning in my stomach that only goes away when I eat, even though it makes me nauseous. It doesn't bother me in the afternoon, just at night while I'm sleeping. It wakes me up and I am sweating profusely in my sleep. I can only assume it's my intestines trying to heal, but why the gas and bloating only at night? Doctor sent off a stool sample to rule out parasites and other causes. I live in Indianapolis and am not sure if there is something going around or not.
