Hi am a female 28 years old, I have been in US for past 3 years, am having smelly flatulence problem after we came here, all the day passing smelly gas, my face started acne, that too very big big. When we go for three months vacation to India I didn t have this problem not even a day. After returning again it started. We are pure vegetarian. Please help me out, it is so depressing and affecting my social life.
