The full explanation.
The simple version
When treatment causes nausea, eating can feel like the last thing you want to do. Small, gentle changes may help you get some nourishment. Your care team can also offer medicine that helps, so please tell them how you are feeling.
Foods that may be gentler
Everyone is different, but many people find these easier during nausea:
- Bland, easy-to-digest foods like toast, crackers, rice, or plain noodles.
- Cool foods with little smell, which can be easier than hot, strong-smelling ones.
- Small amounts of dry food, like crackers, above all in the morning.
- Clear or cool drinks, sipped slowly.
Small changes that may help
Try small, frequent meals instead of large ones. Eat slowly, and do not lie down right after eating. Sip fluids through the day so you stay hydrated.
Ask your care team — effective anti-nausea medicines can make a real difference.
A note on your care
This information is educational and is not a substitute for medical advice. For your own care, talk with your doctor, nurse, pharmacist, registered dietitian, or care team. Tell them about any nausea, even mild nausea. Do not take extra doses of an anti-nausea medicine, or add an over-the-counter remedy, without asking them first.
When to get help sooner
The main risk with nausea and vomiting is losing more fluid than you take in.
- Call 911 or go to an emergency department if you are vomiting blood or something that looks like coffee grounds, or if you are too weak, confused, or drowsy to drink.
- Call your doctor immediately if your temperature reaches 100.4°F (38°C) or higher while you are on chemotherapy. That is CDC's instruction, because fever may be the only sign of an infection, and an infection during chemotherapy can be life-threatening. Know which number to call when the office is closed.
- Call your care team the same day if you cannot keep fluids down for a day, if you have vomited more than a few times, if you have not passed urine in 8 hours or it is very dark, or if you feel dizzy or faint when you stand.
- Call your care team within a day or two if nausea is stopping you eating normally, if your anti-nausea medicine is not working as well as it did, or if you are losing weight without trying.

Common questions
What foods are easier when I feel nauseated?
Many people find bland, easy-to-digest foods gentler — like toast, crackers, rice, plain noodles, or bananas. Cool foods with little smell may be easier than hot, strong-smelling ones. Everyone is different, so notice what works for you.
How should I time meals?
Small, frequent meals and snacks often sit better than large meals. Eating slowly and not lying down right after eating may also help.
What about drinking?
Sipping fluids through the day helps you stay hydrated, which matters when you feel sick. Some people find cool, clear drinks or ginger-flavored drinks easier.
When should I tell my care team?
Always tell them about nausea — there are effective anti-nausea medicines, and they can adjust your care. Contact them right away if you can't keep fluids down, are vomiting a lot, or feel weak or dizzy.

How this page was created
Cancer Explained does not originate medical claims. Every page restates guidance already published by the National Cancer Institute, the CDC, the USPSTF and the FDA, in plain language, with the source cited so you can check the original yourself. AI does the translating and organizing; automated checks test claims, citations, clarity and safety before anything publishes. We do not employ clinicians and do not intend to — our work is translation and navigation, not clinical judgment. Nothing here is personal medical advice, and no page can account for your particular situation.
Editorial status — Source checked. This page was written with AI assistance and checked line by line against the sources listed on it. That confirms the sources support what the page says. It is not a medical review, and it does not confirm the page is complete or right for your situation.
General education — varies by person. Answers genuinely differ between people. This page explains what commonly varies and points you to your care team for your situation.
Human medical review: not completed. Pages here are not signed off by a clinician before they publish. That is not an oversight we are quietly working around: we restate published guidance and cite it, so the authority belongs to the source rather than to us, and every page names where its claims come from — you can verify us instead of trusting us. Where a volunteer clinician has reviewed a page, their name and credentials appear on it; where no name appears, no clinician has checked it. We are glad to have reviewers and are recruiting them, and we do not hold pages back waiting for one. Use this site to understand your situation and to ask better questions of the people treating you.
