There are various tools you can use to convert from pdf and epub to the mobi format that the Kindle app can read. The one I use is Calibre, and it works pretty well. Epub files generally convert without problem, but pdf files might be harder, depending on how complex the pdf is.
Irritation of the stomach from spicy foods, smoking, alcohol, or infection with a bacteria called Helicobacter pylori may all cause symptoms of indigestion, which might include excessive burping. Burping is rarely a sign of a serious medical problem.
Tweet. Burping is expelling of the air and other gases from the stomach through your mouth. Sulfur burps are those which smell of rotten eggs or sulfur. The smell comes from hydrogen sulfide (H2S), a gas which is present in sulfur proteins. sulfur burp is when gas is dispelled from a person's mouth, like a belch, and is accompanied by a strong, foul odor. This odor is similar to the smell of rotting eggs or to the foul smell of sulfur.
