What would cause severe swelling in both feet and legs with stomach bloating?

This only a SUGGESTION. Try searching the internet for "gout". I'm not a doctor, but it's one possibility. You won't have gout if you're skinny and starving... You will probably have a rich diet, probably including daily alcoholic drinks --if you have gout. That's why it's called the rich man's disease. Poor blood circulation can cause this too.
