I often keep burping after a meal for quite sometime, even after drinking enough water. Occasionally it's accompanied by gas and stomach ache followed by a semi loose motion of stool, the kind which happens when one has a stomach upset. This goes away after the stool is passed. This happens mostly when I eat outside food and very rarely when I eat home cooked meal as well. I have noticed this for past few months. Burping has become frequent after meals. Could you suggest a possible remedy or a diagnosis I should go for.
