End stomach bug misery with these doctor-recommended remedies.

Flu season is upon us, which means it’s also the season for stomach flu—which isn't influenza, of course, but a catchall phrase for that miserable mix of diarrhea, nausea, vomiting, and stomach cramps usually caused by a type of virus called norovirus.

Winter is a common time for norovirus because of the increase in the number of holiday-related meals, since norovirus can be transmitted through food that's been prepared by an infected person, explains Niket Sonpal, MD, assistant clinical professor at Touro College of Osteopathic Medicine in New York and St. George's University School of Medicine, specializing in gastroenterology and internal medicine. “Additionally, in the winter, we tend to spend more time indoors with people who are sick, and hand washing may decrease because it’s cold. Thus, the virus spreads more easily,” says Dr. Sonpal.

Hold on, what exactly is norovirus?

Let's just be frank: Norovirus is extremely not fun. According to the Centers for Disease Control and Prevention (CDC), norovirus is an extremely contagious virus that causes diarrhea and vomiting—and literally anyone can get it.

Aside from vomiting and diarrhea, other symptoms of norovirus include nausea and stomach pain. Even more bad news? You can't totally prevent norovirus—it spreads easily and quickly through infected people and contaminated food—but you can do your best to lessen your risk of getting it, like  washing your hands frequently and making a point to not share foods or utensils with people who are already infected can help you dodge the stomach flu.

But what if it's too late and you’re already doubled over in your bathroom? While there’s no cure for norovirus, these tips will help you feel better sooner—including what you should eat when the last thing you want is food.

1. Drink lots of fluids—but not just water. 

The risk of dehydration is a big deal when you have norovirus. “Fluids are critically important, since you’re losing vital bodily fluids through sweating, vomiting, and diarrhea,” says Dr. Sonpal. But keep in mind it's not only fluids you're losing—you're also depleting your body of sodium, potassium, and other minerals (aka, as electrolytes), which also need to be replaced.

Because of that, drinking only water isn't the answer, since that will only deplete those electrolytes further. The solution? Try Pedialyte, or a similar oral electrolyte solutions that contain salts and sugar as well as water, if you have severe diarrhea.

“If you’re having trouble keeping liquids down, try taking small sips at regular intervals or chewing ice chips.” If you can't keep anything down or start showing signs of dehydration like a headache, muscle cramps, dark yellow pee, or not being able to pee very much, call your doctor or consider going to urgent care. You may need IV hydration.

2. Get lots of rest. 

You won’t get any points for coming into work if you’re basically hugging a toilet all day. (This is especially true if you work around food or people who are more susceptible to getting sick like children or the elderly.) Plus, “when you have the stomach flu, your body needs rest in order to fight off the infection,” says Dr. Sonpal. “Get plenty of sleep and reduce the amount of activity you normally do during the day. This is doctor-recommended Netflix binge time.”

3. Try eating these doctor-recommended foods. 

No, it's not for weight loss—the BRAT (bananas, rice, applesauce, and toast) is the recommended diet to start once you feel like you can stomach solid foods again.

"These four foods are easy to digest, contain carbohydrates to give you energy, and replenish nutrients," says Dr. Sonpal. Bananas help replace the potassium you lose through vomiting and diarrhea, and applesauce contains pectin, which puts the brakes on diarrhea. Also, both brown rice and whole-wheat bread contain fiber, which can be tough on your raw, inflamed intestines. So stick with the easier-to-digest white versions—and then just switch back to your whole-grain go-tos when you're feeling 100% again.

4. Soothe your stomach with some ginger. 

“Some people use ginger to control their [stomach flu] symptoms,” notes Van Pham, DO, primary-care physician at MemorialCare Medical Group in Long Beach, California. Whether ginger chews or ginger tea, some form of this remedy is worth a try—if you can keep it down. But remember that this isn't a cure—even if ginger does help relieve your symptoms, you're still contagious and should continue to take it easy.

5. Try some anti-diarrhea meds. 

Over-the-counter anti-diarrhea medication, like loperamide hydrochloride (Imodium) or bismuth subsalicylate (Pepto-Bismol), can provide some short-term relief, but “check with your doctor before trying OTC options,” cautions Dr. Sonpal. “It’s often better to let your body clear the diarrhea then to slow it down with these meds.” And remember: Pepto-Bismol isn’t safe to take if you’re allergic to aspirin or other salicylate drugs, and should never be given to kids under the age of 12.

6. Pop Tylenol for stomach cramps

“Acetaminophen (Tylenol) is often recommended for the stomach flu, unless you have liver disease,” Dr. Sonpal notes, since it relieves aches, has fewer side effects than ibuprofen, and is less likely to irritate your stomach.

When should you see a doctor?

If more than four days have passed and you're still experiencing the awful symptoms, call your doctor. This is especially true if you can’t keep down any food or water, are running a fever, have severe abdominal pain, or notice blood in your stool. If that’s the case, “seek help immediately,” says Dr. Pham.

When you do start feeling better, don’t host a holiday party just yet. “Even after you recover from diarrhea and other symptoms, you can still pass [the stomach flu] on to others for 2 to 3 more weeks,” Dr. Pham cautions. You’ll continue to shed the virus through your stool during that period, so be extra cautious about washing your hands after you use the bathroom and before you handle any food.
