As long as your symptoms eventually disappear, they aren't serious. Nevertheless, if you are experiencing symptoms of a serious illness, including fever or vomiting, or if your bloated stomach does not go away, you should seek medical assistance. The presence of frequent indigestion and bloating that is unrelated to food or appears to be caused by something more serious may signal something more serious is going on. There are potentially serious causes, such as stomach ulcers and stomach cancer.
