Possible to get stomach discomfort because of meditation? I have been starting meditation more recently for about twenty minutes at a time. I am able to slightly focus on the breath and have noticed I focus better when the breathes are long. I have also noticed after these sessions I may have air in my stomach possibly that leads to gas buildup and stomach discomfort. Is this something others have had before? If so how can I prevent this?
Possible Causes:


You are eating too much and too soon to doing sitting meditation. While meditating or doing any relaxing activity, your digestive system functions much better thus producing more gas along with other things. Solutions: eat less and have at least an hour or two gap for meditation or try a different posture like standing/non-lotus.
You are stresing out (more than normal) while you are trying to relax (meditate) thus causing intenstinal ineffectiveness. Let go of those thinkings and be present and pleasant.
You are already quite gassy. Have some probiotics in the form of yogurt, kombucha, or fermented food.
