An upset stomach can be caused by many different things. Marla Ahlgrimm lists pregnancy, a stomach bug, and food poisoning as three of the most common. The retired pharmacist explains that some people may find relief through non-pharmaceutical remedies.
According to Marla Ahlgrimm, one of the quickest ways to settle and unsettled abdomen is to sip a glass of cold water. Ginger ale is another liquid that many physicians recommend, and especially for pregnant women or those who have an aversion to Pepto-Bismol. Ginger ale works because of compounds known as gingerols. Gingerols can relieve inflammation and help quell pain caused by gas. Further, ginger is soothing to the lining of the stomach.
