Yes, post nasal drip can sometimes cause stomach problems, which is best treated by treating the nasal problems.
That makes sense because its not like my body doesn't want to eat, it more feels like my body doesn't need to eat.
The nasal symptoms might be triggering your stomach problems. I would recommend seeing a specialist like an ENT doctor to be evaluated.
My diet hasn't really changed since I eat at the dining facility and they are all the pretty much the same Air Force wide. One thing I notice is that my appetite peaks when I see/think of fatty and greasy food.
The climate might be the reason that your nasal symptoms have changed. I assume your diet changed a lot when you got home which might be the reason for you stomach problems. Can you try changing your diet to be more like your diet in Guam?
Coming up on a month this Tuesday. No, no nausea... I still workout, go to work, and preform my daily routines without hinderence.
