When I start to eat gasses forms in my gut and also gasses forms when I also drink even in small amounts may it be water or other fluids. So I would have a trouble sitting down as I could not pass it all out easily. It always requires me to lay down so that I could fart with ease.
It maybe a symptom of digestion problem due to many reasons like my medicines, my sensitivity to certain foods, and my inability to properly digest some kinds of foods. So sometimes it maybe funny to somebody else that I would pass gas inadvertently but it really is a health issue that I do not have any control of.
In my culture most people make fun of those who did passed gasses not knowing the whole story behind the foulness of the situation in one's condition. So I would always either avoid such places or tell that there will be an incoming putridity coming along and everyone sensitive should take cover.
