Nausea is one of the most common and emotionally distressing side effects of cancer treatments like chemotherapy, radiation, and certain other medications. While it may not always be avoidable, the right dietary choices can significantly ease the symptoms and discomfort. It helps patients maintain strength and nutrition during cancer treatment.

In this blog, we’ll explain more about the practical and gentle dietary tips to help manage nausea and support the overall well-being of cancer patients.

What are the Dietary tips to manage nausea during cancer treatment

To manage nausea during the cancer treatments, you may need to focus on eating small and frequent meals. Additionally, include low-fat foods and stay hydrated with the consumption of liquids as well. Here are a few dietary recommendations suggested by oncologists.

These may include:

1. Eat small meals frequently

If you were diagnosed with cancer recently or are undergoing cancer treatments, you may tend to experience nausea. If you are experiencing nausea, then avoid eating large amounts of meals, because it can overwhelm your digestive system. 

Instead of eating large amounts of meals, consider eating 5 to 6 portions of small meals or snacks throughout the day.

Always keep your foods in a small quantity, but make sure that they are nutritionally rich and healthy for you.

2. Choose easy-to-digest foods 

Always choose easy-to-digest foods for eating if you are experiencing nausea due to cancer. Eating strong flavors and greasy foods might trigger nausea in people. Always stick to easy-to-digest foods, including plain rice, potatoes, pasta, toast, or bananas. 

Additionally, include applesauce, oatmeal, or soft-cooked vegetables in your diet. Always try to avoid spicy, fried, or highly cooked or seasoned foods. 

3. Stay hydrated and drink water a lot (sip slowly) 

If you are not drinking enough water then it can make you nauseous. Dehydration can make people nauseous most of the time. Try to stay hydrated and always sip water slowly and avoid gulping altogether. You can also drink herbal teas, electrolytes instead of drinking water. 

If you can’t tolerate liquids, then try to suck ice cubes and frozen fruit popsicles in your diet. Avoid sugary drinks and caffeinated drinks as well.

4. Include Ginger and peppermint

Ginger and peppermint are known for their nausea-relieving properties. You can add a small piece of ginger to your tea, or chew a small piece, or eat ginger-flavored candies to control your nausea. You can also take peppermint tea or peppermint oil for aromatherapy.

Additionally, including fresh ginger in soups and foods is good and beneficial for getting relief from nausea.

5. Eat room- temperature foods

Eating hot-temperature foods can intensify the level of nausea in cancer patients. Instead of eating hot foods, consider eating cold or room-temperature foods. You can try foods like sandwiches, salads, yogurts, or chilled soups to get some relief from nausea. Consider taking smoothies made with fruits, protein powder, and peanut butter as well.

6. Avoid lying down immediately after eating

Always give your body enough time to digest. Here are the few things to watch out for:

  • Try to stay upright or sit down for a while, at least for 30 to 60 minutes after eating.
  • If you need some rest, then recline a bit with support; if rest is still needed, avoid lying flat immediately.

7. Limit consuming fatty and sweet foods

Eating high-fat and sugary foods that are harder to digest normally, and it may generally increase nausea in people. Avoid the consumption of foods like cream-based sauces, heavy desserts, and fried foods.

If you are experiencing nausea continuously, then opt for baked, grilled, or steamed dishes such as hard steamed vegetables instead.

8. Add lemon and citrus flavors in the food

If you are feeling nauseous, then adding a lemon can cut through the nausea and help to leave a refreshing taste in the mouth. Adding a lemon slice to your drinking water or tea can enhance your taste buds and even uplift your mood. You can also try citrus-flavored candies; they will improve and eliminate your nauseous feelings. 

Some studies have suggested that the scent of fresh lime and lemon may also help to curb nausea in people.

9. Eat when you feel hungry or starving

Always listen to your body; if you feel hungry early in the day, eat more essential meals in a day. If you are feeling hungrier in the evenings, then consider eating calorie-dense meals at that time.

10. Taking consultation from a dietitian

Every cancer patient’s body reacts differently to cancer treatments. Some might experience fewer symptoms, but most of the cancer patients experience nausea, mouth sores, and hair loss as well.

If you are experiencing nausea for more than 2 weeks, without any improvements, then consult a registered oncologist and dietitian and customize your diet plan.

When to consult a doctor?

If you are diagnosed with cancer and experiencing nausea as a side effect of cancer treatments like chemotherapy, radiation therapy, or other treatments. Then consult a doctor immediately, without any hesitation. Do not wait any longer, until it becomes a severe condition.

If nausea becomes consistent and prevents you from eating or drinking, then consult an oncologist as well as a dietitian. There are medications like antiemetics used to control nausea and manage to lead a healthy life. Seek medical consultations because no one should suffer in silence!
