What Are the Possible Causes of an Upset Stomach?
Commonly, an upset stomach is caused by gas or bloating from benign causes like poor digestion of certain foods or additives.
Explanation
There are a variety of causes of an upset stomach that run the gamut of common to very uncommon. Common causes of an upset stomach include poor digestion of certain foods (ie: dairy products, heavily processed foods, fried foods, etc. ), overeating, food poisoning or even stress. If persistent or intense, less common causes should be considered like an obstruction from a tumor, small intestinal bacterial overgrowth, gastric motility disorders or functional bowel issues like irritable bowel syndrome.
