My husband is feeling stomach bloating, almost ever day or every other day, following heart attack and stent procedure three weeks ago. No shortness of breath. He has told a local cardiologist about the bloating, who said probably just normal post-op recovery. But it is worrisome to my husband, and uncomfortable. He is 61, slightly overweight, works out regularly (prior to stent surgery, cardio and weight lifting), post-op he is now up to walking 2 miles each morning, and has kept a modest diet of lean meat and veg, not as much appetite as before, which he welcomes. But the bloating worries him, b/c that was the feeling he had during his heart attack, but this is not as severe. Suggestions?
