### input:
Hi,I have been experiencing abdominal bloating and discomfort (but not real pain) since about 5 months back. I have performed an endoscopy which found grade A gastritis as well as an hiatal hernia, and a colonoscopy which found nothing out of the ordinary. In connection with this they took blood tests and I have some concerns when I look at the results compared to the ones I took a year ago (I have not yet seen the doctor to discuss the results). It appears that my AST and ALT levels have gone up from 19 and 31, to 74 and 118 respectively. My blood urea nitrogen has also dropped from 13 to 7 in the same period. As far as I understand this would indicate some sort of inflammation in the liver, and I am worried that it may be something like Hepatitis (we went on a Caribbean cruise just before this bloating started, and if I understand correctly you can get certain types of Hepatitis from contaminated food). Could this be the cause of the bloating if that is the case? Is there any other possible diagnosis besides Hepatitis, and if not, is a treatment for it complicated?

Both are self limiting viral infections. Other causes for liver enzymes to rise could be use of alcohol, fatty liver and any other
