Chemotherapy can irritate the areas of your brain that control nausea, as well as the lining of your mouth, throat, stomach, and intestines.

Nausea and vomiting can also be caused by stress, or just the thought of having chemo.

It’s important to manage nausea because it can keep you from eating and drinking. And when you don’t eat or drink enough, your body doesn’t get the vitamins and nutrients you need for energy and to heal.

During your chemo treatment, you’ll be given medication that can help prevent or control nausea. Medications can be used at different times, like before, at the time of, or after you receive chemotherapy, so take your medication exactly as instructed by your healthcare provider.

Medications work differently for different people. If the medication you are taking isn’t controlling your nausea, tell your healthcare provider. You may need to try a different one, or take more than one kind, to feel better.

Even when you have nausea, it’s important to drink at least 8 to 10, 8-ounce glasses of liquids every day. This will keep you from becoming dehydrated. Cool, clear, unsweetened fruit juices, or light-colored sodas that have lost their fizz, are good choices. You might find it helpful to dilute fruit juices by adding water. It’s best to drink small amounts of these liquids slowly, at least 1 hour before or after you eat.

Speaking of eating, eat small meals often, instead of just a few large meals.

Avoid eating foods that give off an odor, or are fried, greasy, creamy, rich, or spicy.

Eat your meals slowly and at room temperature or cold. This will help you if you are bothered by strong smells. Odors from cooking or hot meals can make you nauseous.

Chew your food well and sit upright for 2 hours after you eat to help you digest your meal.

Try eating dry foods, such as crackers, cereal, or toast before you get out of bed in the morning. This can prevent nausea and dry heaves.

You might also try eating a light meal before your chemotherapy treatment.

Sucking on hard candy, such as mints or sour candies, may help control nausea.

And finally, relaxation methods, such as music, deep breathing, yoga, and meditation may help relieve nausea.

If you still feel nauseous even after taking your medication, or if you’ve been vomiting for longer than 24 hours, call your healthcare provider. You can also call if you have any questions or concerns about your treatment.
