Bloating means a increase in diameter of the abdominal area and the patient feels a full and tight abdomen.
Gas and bloating is a sign that food is not being digested correctly by the body.
So as you describe you have a history of taking food differently outside your home.
So chances are that this is simply bloating associated with the diet.
Overeating is common cause of bloating and probably you may have overeating history while your buisness trip.
I do think that this is a temporary functional problem.
Simethicone is usually prescribed by doctors in such cases.
I hope this helps
Can I be bloated for a few days? I got back yesterday, and I am still bloated and distended.
Yes it is possible to feel distended and bloating for few days.
You can try to fast for a day and see if it helps.
In many cases fasting for a day helps to clear the toxins associated with undigested food.
