Best foods to eat when you have a stomach bug

Viral gastroenteritis is an intestinal infection marked by watery diarrhea, abdominal cramps, nausea or vomiting, headache, muscle aches and sometimes fever. It's often called a stomach bug or the stomach flu, but it's not actually the flu or influenza, which is a respiratory illness. This infection often develops though contact with an infected person or by ingesting contaminated food or water.

An upset stomach is a common symptom of a stomach bug, which can make eating sound unappealing, even though you may be hungry. Knowing what to eat is difficult because you don't know what will agree with your stomach.

Follow these tips for fueling your body when you have viral gastroenteritis:

• Let your stomach settle.Avoid eating solid foods for a few hours. Instead, drink liquids like broths, teas, sodas or noncaffeinated sports drinks.
• Hydrate. Focus on drinking in small amounts of liquid frequently to stay hydrated.
• Ease back into eating. After you can tolerate drinking clear fluids, start eating smaller meals of bland, low-residual foods, such as mashed potatoes, plain noodles, crackers, toast, gelatin, bananas, rice and chicken.
• Be cautious with medications. It's best to use over-the-counter medications like ibuprofen sparingly as they can cause an upset stomach. Discuss your medications with your health care team to avoid any potential side effects. If your symptoms are severe, you may need to use an over-the-counter medication to help decrease diarrhea symptoms or an anti-nausea medicine to help you keep food and fluids down with vomiting.

The main complication of a stomach bug is dehydration, which is a severe loss of water and essential salts and minerals. You can lower the risk of dehydration by drinking enough fluids to replace those lost from vomiting or diarrhea.

Depending on the cause, viral gastroenteritis symptoms generally appear about one to three days after exposure. Symptoms can be mild or, at times, severe and last for a few days to a week.

When to see a health care professional

Although viral gastroenteritis is extremely common, it can usually be managed at home. Red flags or worrisome symptoms that would prompt a visit to your health care team are severe dehydration, not being able to keep fluids down, bloody stools, severe abdominal pain or when symptoms last longer than one week. Young children, older adults and people with compromised immune systems are more likely to have complications related to viral gastroenteritis.

Prevention

Good hand hygiene and proper food handling are essential to prevent you from getting sick and to limit the spread of viral gastroenteritis within a household, school, workplace and the community. Ensure you wash your hands with soap and water, especially after using the bathroom, before preparing food and eating. Stomach bugs most commonly are seen in the winter and spring, so it's important to be diligent, especially this time of year.
