What causes "gas" in a person and can you take to many antiacid pills?

Answer 1

Gas is caused by swallowed air
& normal breakdown of certain undigested foods by harmless bacteria naturally present in the large intestine (colon).

Antacids don't really help for gas per'se, but Beano works pretty good to supress the gas without you having to "fart", especially if you are unable to because you're in public or at work. :)
