Hello..... Bloating occurs due to gaseous distension of abdomen. This excessive gas formation having multiple reasons include intestinal infection, change of flora of intestine, indigestion, acid peptic disease and delayed gastric emptying are common. This bloating will lead to nauseating feeling with gastric distension that may lead to diaphragm upward push that can cause short of breath and sweating with restlessness. Smoking and drinking are important precipitating factors for bloating. But we should also keep in mind of heart pathology. Because heart symptoms are very much similar to these above problems and related to smoking and drinking. So in my opinion kindly rule out any heart pathology by proper cardiac investigation meanwhile you can take Tab Pantoperazole with Domperidon twice a day before meal, Tab Charcol thrice a day after meals with Syp Sucalfate 10 ml thrice a day. Thank You
