** Thanks for contacting with your health concern 1. Abdominal distension is typically a symptom of an underlying disease or dysfunction in the body rather than an illness itself, so without getting a chance to examine you directly, I m of the following opinion: i. As there is history of 5 drinks per day: distension could be because of liver dysfunction [either portal hypertension or cirrhosis] PS. Consult a Hepatologist for necessary examination and investigations ii. As you are a diagnosed case of IPF [idiopathic pulmonary fbrosis], thus remember that in chronic cases, the right side of the heart gradually gets involved secondary to lung disease [which we call as cor pulmonale], as such one can see leg/abdominal swelling in fibrosis patient PS. You and your doctor must re-evaluate your current situation. iii. Initially, if rest and low salt diet, don t work to relieve symptoms, call your doctor in addition to treating the cause of the ailment. [since the abdominal mass is getting bigger]
