To treat symptoms of the stomach flu, Mayo Clinic recommends a variety of self-care measures, including avoiding solid foods, drinking plenty of hydrating liquids and eating bland, easily digestible foods. Allow for plenty of rest and avoid dairy products, caffeine, alcohol, nicotine, and fatty and highly seasoned foods until health improves. No specific medical treatment is available for the stomach flu, according to Mayo Clinic.
According to the Healthline, the stomach flu, also known as viral gastroenteritis, is an inflammation of the stomach and intestines that is caused by many different viruses. Symptoms can persist from one to 10 days and include watery diarrhea, nausea, vomiting, abdominal cramps, fever, chills, headaches, sweaty or clammy skin, muscle aches, loss of appetite and weight loss. The stomach flu is highly contagious and spreads easily from close contact with an infected person as well as through contaminated water or food.
Mayo Clinic recommends sucking on ice chips or sipping frequently on water when food and drink can't be held down. Drink clear soda, clear broths and non-caffeinated sports drinks. When the stomach has settled, gradually reintroduce plain foods such as crackers, plain toast, bananas, rice and unseasoned chicken into the diet. Use pain relieving medication sparingly, as it can make the stomach more upset.
