After you've had the stomach flu, it is important to take it slow as you re-introduce foods back into your diet. The stomach flu can leave your stomach queasy and sensitive even after the viral infection has subsided. Because the most common symptoms of the stomach flu are vomiting, nausea and diarrhea, your entire digestive system needs a few days to recover from being under attack. Talk with your doctor before you modify your diet to treat any medical condition.
About
The stomach flu is a viral infection of the intestines that lasts for one to three days. The stomach flu is not related to the regular flu, which is caused by the influenza virus, but it is caused by one of four different viruses. The stomach flu is highly contagious and is spread through human contact. You can prevent the stomach flu by washing your hands often, disinfecting common areas and staying vaccinated. If someone appears to be sick, avoid being in their presence. There is no cure for the stomach flu except rest and diet modification.
Re-Introducing Foods
After your symptoms are gone, talk with your doctor about what foods you should eat first. Begin by eating small meals that contain bland and easy-to-digest foods that will help calm the stomach and promote regular bowel movements. Foods that might help are potatoes, bananas, rice, bread, toast, crackers, cooked carrots and chicken without the skin. Drink plenty of water to keep the body hydrated. You can also drink herbal teas, chicken broth and sports drinks that are fortified with electrolytes.
Avoid Certain Foods
Avoid foods that could cause the digestive system to become aggravated. These foods include fatty foods, high-sugar foods, foods high in fiber and foods that are spicy. Do not eat these types of foods until your doctor says it is OK. Dairy products may cause further irritation and should be avoided. Stay away from foods and beverages that contain caffeine and alcohol, such as sodas and coffee. Avoid consuming any known food allergies or intolerances.
Consideration
The stomach flu can cause dehydration, a serious medical condition where the body is depleted of water and salts that could lead to death. If you suspect that you're dehydrated, call your doctor. Common symptoms of dehydration include fatigue, feeling lethargic, dry skin, dry mouth and thirst. Severe cases of dehydration may require hospitalization.
