What To Eat, Drink, and Avoid When You Have the Stomach Flu
If you’ve ever had a stomach flu, you don’t want a second bout of it. Knowing what to eat and drink when you’re down with the stomach flu helps you heal faster and avoids prolonging those miserable symptoms.
Our board-certified internal medicine physician, Samuel I. Fink, MD, provides comprehensive primary care to help you manage chronic conditions and recover quickly when you’re sick.
What is stomach flu?
Stomach flu, or viral gastroenteritis, isn’t an influenza virus that causes high fevers, respiratory symptoms, and joint pain. Instead, it’s usually the result of a norovirus or rotavirus. Hallmark symptoms include diarrhea, nausea, vomiting, and stomach cramps; you may also have a fever. Thankfully, it usually lasts only one to three days.
Stomach flu is very contagious. It spreads through direct contact with contaminated surfaces or from contact with people.
If you’re sick with the stomach flu, Dr. Fink provides the following tips on what to eat and drink to help you heal faster.
Eating when you have the stomach flu
When stomach flu hits, you likely aren’t interested in eating much, but what you choose to eat matters. Some foods can make diarrhea much worse.
Eat bland, easy-to-digest foods that won’t irritate your stomach, such as:
- Bananas
- Plain rice
- Plain, dry toast
- Crackers
- Applesauce
- Potatoes without butter or sour cream
Once you begin to feel better, you can add scrambled eggs and other lean protein like chicken or turkey without the skin.
Hydrating when you have stomach flu
Two hallmarks of stomach flu are diarrhea and nausea that may lead to vomiting. Both can dehydrate you quickly. It’s important to stay hydrated when you have stomach flu.
Sip beverages throughout the day, including water, electrolyte drinks (sports drinks or Pedialyte), ginger or peppermint tea to relieve nausea, and clear broths.
If drinking liquids is difficult, suck on ice chips or ice pops to slowly replenish fluids without overwhelming your stomach.
What to avoid when you have the stomach flu
You may love milk, yogurt, cheese, and other dairy products, but they don’t love you back when you have stomach flu. Dairy and other foods and beverages can worsen your symptoms.
While you’re recovering, avoid:
- Dairy products, which can lead to prolonged diarrhea
- Caffeine, which is dehydrating
- Alcohol, which can worsen dehydration and nausea
- Greasy, fatty foods, because these foods are hard to digest
- Spicy foods, because they may irritate your stomach lining
- Sugary drinks, which can worsen diarrhea
It’s better to be safe than sorry when it comes to eating and drinking with the stomach flu.
