Flatus commonly termed as Fart refers to the gas inside our Gastrointestinal tract which is released as a normal physiological process throughout the day.As hydrogen sulphide gas is there in the tract which is foul smelling, hence flatus is bad smelling. I hope that’s a normal phenomenon. If you have constipation or bowel problems , you can try some laxatives for some days. This may relieve your tension a bit. Avoid non veg food, focus on a vegan diet. That’s recommended. Hope this helps . Thanks
