I have IBS, and this sounds more like your dietary choices than a medical issue. Identify the food that is causing the gas the most, and eliminate them for the time being.
But make sure you eat food with fiber...I ate a ton of carb laden, fiber free foods to avoid IBS symptoms, and it just resulted in weight gain and a later carb addiction.
Or if I order food from wherever the office is eating out at instead of bringing my own food to work, I also don't have as much gas.
Unless they always order at places with zero fiber or triggers for you, this might be more wishful thinking than reality, lol.
And I hate to be bearer of embarrassing news, but I had an employee that had a similar issue and co-workers definitely noticed but never mentioned it to him (though they talked to others about it frequently). I mention this only so that you can make an informed choice as to if/how you want to deal with it.
Hang in there...you can conquer this if you track what you eat, identify your triggers, and work on increasing your fiber over time. Good luck!!
