Best remedy for gas/ bloating?

First find cause: Irritable bowel syndrome (ibs) is associated w/ abdominal discomfort, altered /alternating stool pattern, accompanying nausea, bloating, gassiness. Often improved by stooling, ibs is defined by changes in perception of gut distension, motility, sensation. Diet & emotional stress play significant roles. Need however to rule out first inflammation, ischemia, dysmotility & infection before treatment.
