Depends on details: A simple tummy ache with symptoms like nausea, vomiting, or diarrhea, whether at home or traveling, may be from a virus infection, bacteria infection, or contaminated food. A typical normal healthy person usually recovers easily. Taking a Pedialyte popsicle or 2-3 oz of Pedialyte hourly, plus drinking or eating little else for a day, may settle things down. If worrisome, a Dr. should recheck.
