Treatments for a stomach virus include not eating solid foods for a few hours, sucking on ice chips, sipping clear liquids and easing back into eating, according to Mayo Clinic. Proper care keeps the patient more comfortable and helps prevent dehydration.
When the patient begins to feel better, he should try bland solid foods, such as soda crackers, rice, chicken and bananas, reports Mayo Clinic. However, if nausea returns, he should stop eating, and avoid dairy foods and beverages containing alcohol or caffeine. Nicotine sometimes makes the effects of the virus worse, so avoid the use of tobacco products, and avoid foods that are high in fat or spicy.
