He has terrible abdominal swelling, fluid retention, and feeling such fullness after any exercise. We cannot explain this. He is on a very healthy diet, low
sodium, low carb, and not super high protein, just well balanced. This is causing him to be extremely uncomfortable. Any ideas on how to prevent this, what could be causing this, or what to do to treat it? He takes hydrochlorothiazide twice daily, 12.5mg and it does help, but not completely. He drinks lots of water.
