You have given far too little information for anyone to begin to get an idea of the reason for this bloating.
Water retention (yes, a yin condition) can and does have many possible causes and underlying conditions that can be aggravated by consuming too much salt (including miso, tamari, umeboshi, salty condiments) and/or animal food, but sugar and other yin foods and liquids can also cause bloating.
You seem to to saying that your bloating is confined to the belly and that your intestines are inflamed. In that case you might find some helpful info here:
