A person can have nausea with or without vomiting. If it’s caused by chemo, nausea can happen on the day you get your treatment and can last for a few days – depending on what drugs you get. If you’re getting radiation therapy to the belly, chest, brain, or pelvis, nausea can start shortly after treatment and last for several hours. Nausea and vomiting can have other causes, too.
Be sure to tell your doctor or nurse if you have nausea or are vomiting because there are medicines that can help. These medicines should be taken on a regular schedule, or around the clock, as prescribed by your doctor. And if a certain medicine doesn’t work, your doctor or nurse may be able to recommend another one. It may take a few tries to find the medicines that work best for you.
What to do
- Eat 6 to 8 snacks or small meals a day, instead of 3 large meals.
- Eat dry foods, like crackers, toast, dry cereals, or bread sticks, when you wake up and every few hours during the day.
- Eat foods that don’t have strong odors.
- Eat cool foods instead of hot or spicy foods.
- Avoid foods that are overly sweet, greasy, fried, or spicy, like rich desserts and French fries.
- If you need to rest, sit up or recline with your head raised for at least an hour after eating.
- Sip clear liquids frequently to prevent dehydration. Clear liquids include broth, sport drinks, water, juice, gelatin, and popsicles.
- Ask your doctor about medicines to prevent or stop nausea.
- Try bland, soft, easy-to-digest foods on scheduled treatment days. Foods like Cream of Wheat and chicken noodle soup with saltine crackers may settle the stomach better than heavy meals.
- Avoid eating in a room that is warm, or that has cooking odors or other smells. Cook outside on the grill or use boiling bags to reduce cooking odors.
- Suck on hard candy, like peppermint or lemon, if there’s a bad taste in your mouth.
- If you are vomiting, dehydration can become a problem. You’ll need to drink clear liquids as often as possible during this time. After you have vomited, rinse your mouth, wait for about 30 minutes, then try to drink sips of a clear liquid like apple juice, cranberry juice, flat soda, or broth, or take bites of frozen flavored ice.
