<s>[INST] My father has been diagnosed with end stage congestive heart failure. He has a big problem...mostly in the late afternoon or evening hours...when he gets a painful build up of excess gas and belches a lot.  Is there a connection between the heart disease and excessive belching and gas? [/INST] Hello. I read your question carefully, and I understand your concern. Although rare, they may be connected. In late stage congestive heart failures (CHF), due to heart pump failure, every organ system suffers from not enough blood delivered by the failing heart. My opinion is that it is a slight symptom, in this big picture. I recommend a diet with restricted salt and taking all the CHF medications regularly. I hope I was helpful. Good day </s>
