Drinking fluids high in electrolytes treats symptoms associated with a stomach bug, or what is more technically known as gastroenteritis, as listed by WebMD. A person with this illness may be dehydrated, and it is necessary to replace all necessary nutrients.
Common symptoms associated with gastroenteritis include stomach pain, cramping, fever, nausea and a headache, as listed by WebMD. A person with the sickness may also experience diarrhea and vomiting. One of the biggest health risks associated with gastroenteritis is dehydration, which is why a person suffering from the illness needs to consume beverages high in electrolytes. Electrolytes are minerals that regulate water levels, muscle function and blood pressure, as listed by Medical News Today.
Since gastroenteritis is caused by a virus, it is important to avoid food and water that may be contaminated, as stated by Mayo Clinic. In addition, frequent hand washing reduces the risk of contracting the virus. Antibiotics are ineffective in treating the illness. A person diagnosed with gastroenteritis should limit consumption of solid foods to let the stomach settle and avoid caffeine, alcohol and nicotine as well. Finally, medications such as ibuprofen and acetaminophen should be used sparingly, as they can contribute to liver toxicity.
