I can understand your concern. Dilated cardiomyopathy (DCM) can cause reduction in heart functions. This can cause fluid retention in the body. This fluid can accumulate in lungs, abdomen and legs. In lungs, it causes pulmonary edema and this can cause breathlessness on exertion.  In abdomen it causes ascites and this cause heaviness in abdomen. So you should consult cardiologist and get done 2d echo to measure heart function. If it is reduced then you will need diuretics to reduce fluid retention. After diuretics, you will mostly improve. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks. </s>
