I want to start by saying not all cancer patients have chemotherapy drugs and some chemo is not as bad as others. With the great advances in cancer research, there are now a wide range of cancer treatments. In fact the chemotherapies of today have much-reduced side effects compared to those experienced by our parent's generation.

Nevertheless, chemotherapy is still a cancer treatment that many patients dread, and sometimes the side effects are quite harsh, affecting hair growth, causing skin irritability, and a number of other side effects that are described elsewhere on this site.

This article explores what chemotherapy induced nausea and vomiting (sometimes referred to as CINV) are, why they occur, and what you can do about it. But before you read any further please remember that each chemo experience is unique and the below are generalizations.

FAQ about nausea and vomiting caused by chemotherapy drugs

What is the cause of nausea and vomiting in chemo patients?

The exact cause of nausea and vomiting in patients receiving cancer chemotherapy is still not completely understood. Some studies have shown the brain may be triggered by this cancer treatment to send signals to the body to cause nausea and vomiting (a natural instinct to dispel a harsh drug perhaps?).

Cancer research into this area allows the best anti-nausea medicines to be created. Currently, many anti-nausea drugs that are used attempt to block different parts of the brains pathways to control and prevent CINV.

Who is at risk of nausea and vomiting after chemotherapy?

The doctor prescribing the cancer treatment will say whether it is likely to cause nausea and vomiting. However, not everyone will react in the same way and there are several risk factors that might make someone more vulnerable to nausea and vomiting.

Risk factors that increase your likelihood that someone will have chemotherapy-induced nausea and vomiting include:-

✓ Being female.
✓ Being younger than 50.
✓ There is alot of anxiety.
✓ There is an expectation of CIVN.
✓ There is a history of motion sickness, pregnancy morning sickness or other treatments make you feel sick.
✓ There is a tendency to vomit when ill.

What does chemo nausea feel like and when does it happen?

Although not everyone feels sick during or after chemotherapy if they do it will usually start a few hours after treatment. There are several different types of nausea and vomiting and these are classed as when they occur.

Anticipatory nausea and vomiting is a learned or conditioned response and is the result of previous experiences that led to nausea and vomiting. Anticipatory nausea and/or vomiting can happen before or during cancer treatment.

Acute nausea and vomiting can happen within minutes to hours after treatment is given, and usually within the first 24 hours. This is more common when treatment is given by IV infusion or when taken by mouth.

Delayed nausea and vomiting usually begin after 24 hours and can last for a few days. This is specific to certain types of chemotherapy drugs only.

Breakthrough CIVN happens after you have has anti-sickness treatment/medicines, but have nausea and vomiting anyway.

Refractory vomiting occurs when the anti-sickness drugs stop working and may happen after a few or even after several chemo treatments.

In all the above cases specific support and treatments are available. Any doctor/healthcare professional who is dealing with the chemo would be able to help. If you are the cancer patent reading this and experiencing any of these types o nausea please ask your doctor for help.

Different treatments and lifestyle changes to alleviate nausea and vomiting are discussed later in this article.

How to reduce and control nausea from chemo

There are many things that can help avoid, remove or reduce nausea and vomiting. From changing eating habits to prescribed medications.

Changing eating habits can help with chemotherapy nausea

Changing eating habits can help with chemotherapy induced nausea

Things to try

These anti-nausea tricks that help some cancer patients with CINV

  • If the smell of cooked or cooking food makes you feel sick, try to have cold or slightly warm food.
  • Several small meals and snacks throughout the day, instead of large portions can reduce the feeling of nausea.
  • Chewing food well can trick the stomach into thinking there is less in there and prevent nausea and vomiting.
  • You could try having small meals a few hours before treatment, but not just before.
  • Light, bland foods, such as plain toast or crackers, are better than rich foods.
  • Eat before you get hungry.

Things to avoid

The below are likely to cause or can increase nausea in patients receiving chemotherapy.

  • Fried and fatty foods.
  • Foods that smell strong.
  • Filling your stomach with a large amount of liquid before eating.
  • Too much activity straight after eating.
  • Mixing hot and cold foods.

We also recommend that avoid eating your favorite foods during the time you feel sick.  If you do, they will no longer be favorite foods as you could begin to associate them with nausea and vomiting.

Additions to the diet can help

There are certain foods that can help with chemotherapy nausea:

Ginger

Crystallized stem ginger on its own or adding freshly ground ginger to your favourite dishes, or to hot water or tea to make a soothing drink and are all documents to relieve nausea symptoms.

Sipping ginger ale can also help and has the double bonus of being a fizzy drink, which relieves symptoms also.

Peppermint

Peppermint is thought to slow down gut movement and therefore relieves nausea and vomiting.  That is why sucking mints or drinking peppermint tea can help.

Pineapple

Fresh or tinned pineapple chunks can help keep your mouth fresh and moist.

Drinking well can help

It's always important to try to drink plenty, even if you can't eat.  Small sips slowly through the day can help.

Try drinking these throughout the day:

  • Clear, sweet liquids, like fizzy drinks or fruit juice.
  • Ice cold or clear fluids.
  • Prune juice and hot drinks, which can help to make your bowels work if you are constipated.

Having a fancy water bottle can be a reminder to drink.

Drinks to avoid include caffeine, orange and grapefruit juice, which may irritate your stomach.

Anti-nausea bracelets

Anti-sickness acupressure bracelets can help with the side effects of chemotherapy drugs. These include a hard plastic stud that you position in the middle of the inside of your wrist. The aim of these bracelets is that the acupressure point on the inside of the wrist helps control the sickness. It is suggested that it calms the vomiting center of the brain and reduces nausea.

Anti-nausea wrist bands can help with the side effects of nausea and vomiting.

Focus on your surroundings

  • Try not to lay flat for at least two hours after eating.
  • After eating rest by sitting up or reclining with your head elevated.
  • Get fresh air after eating.
  • Wearing loose clothing can be helpful.
  • Exercising after eating can slow down digestion and increase discomfort.
  • Try not to get over tired because you could find things more difficult to cope with when you are exhausted. If you can, relax and keep your mind off the chemotherapy. Bring soothing music, a funny film, relaxation tapes, or CD’s, with you to chemo, or even a friend

Relaxation techniques

Relaxation techniques such as hypnosis and meditation (focusing the mind), breathing exercises, or muscle relaxation (tensing and relaxing the muscles) can help decrease nausea and vomiting.

Anti-Nausea medicines

There are many types of drugs that can be used to control nausea and vomiting. These are called anti-sickness (anti-emetic) drugs. The type of treatment given depends on the cause of the sickness.

Some anti sickness drugs work on the brain by preventing stimulation of the vomiting center. Others work on the gut by speeding up the rate at which the stomach empties. This helps move food through the intestines quickly.

Treatment for chemotherapy induced nausea is often a combination of different anti sickness medicines and often it's a matter of finding the right one that works for the specific cancer patient. Effective management of chemotherapy long-term side effects management requires a comprehensive approach that addresses not only nausea but also fatigue, neuropathy, and cognitive changes. Patients may benefit from a multidisciplinary team that includes oncologists, nutritionists, and mental health professionals to tailor their care. Furthermore, incorporating lifestyle modifications and support groups can significantly enhance overall well-being during and after treatment. Additionally, nausea management tips for chemotherapy often emphasize the importance of dietary adjustments, such as small, frequent meals that are easy to digest. Many patients find relief through alternative therapies like acupuncture or mindfulness practices, which can also help alleviate anxiety related to treatment. It’s essential for patients to communicate openly with their healthcare team about their symptoms and preferences to find the most effective strategies for their unique situation.

How to cope emotionally with chemotherapy nausea

Please don’t give yourself a hard time if you really don’t feel like eating for a few days after chemotherapy treatment. You can still drink and it is important that you do.  You can make up for lost calories in between treatments. Staying hydrated is key, and there are plenty of nutrition tips during chemotherapy treatment that can help you manage your energy levels. Focus on small, frequent meals that include protein-rich foods, as they can aid in recovery. Additionally, consider smoothies or soups, which can provide essential nutrients without feeling heavy. Opting for easy-to-digest foods can make a significant difference in your comfort levels. Don’t hesitate to reach out to a nutritionist who specializes in cancer care to help customize your meal plans.

Ways to help with chemo nausea that do not involve food

When to contact your doctor

You must tell your cancer care team if you suffer nausea or vomiting because there are many remedies available. But be aware that may take more than several attempts to find the medicines that actually work best for you and you may need a combination for medications and changes in eating habits to help. In addition to consulting with your healthcare team, consider nutritional tips for chemotherapy patients that can help ease these symptoms and support your overall health. Focusing on small, frequent meals rich in protein and healthy fats can be beneficial, as well as staying hydrated with clear liquids. Incorporating gentle, bland foods may also help minimize discomfort while you're undergoing treatment.

Nausea and vomiting can also be caused by medical conditions unrelated to cancer chemotherapy. So please do contact your doctor if: chemotherapy side effects management strategies can include dietary adjustments, hydration, and antiemetic medications to help alleviate these symptoms. Additionally, discussing any emerging side effects with your healthcare team can lead to personalized solutions tailored to your needs. It's important to remember that effective management can significantly improve your quality of life during treatment. Managing side effects of chemotherapy is a crucial aspect of the treatment process. Engaging with support groups and utilizing resources from trusted organizations can provide additional insights and coping strategies. Being proactive about your symptoms not only fosters open communication with your healthcare provider but also enhances your overall treatment experience.

  • You continue to have nausea or vomiting, despite taking anti-nausea medications.
  • Nausea interferes with your ability to eat.
  • You feel bloated.
  • You have been vomiting 4-5 times in a 24 hour period.
  • There is pain or you have a swollen stomach before nausea and vomiting occurs.

Last thoughts

Everyone with cancer and everyone having cancer treatment will respond differently. Please don't let any of the above scare you if you are a cancer patient or know someone with cancer. And don't forget that if you or your loved one does get CIVN there is plenty you can do about it. Skin changes during chemotherapy treatment can vary significantly from person to person, with some experiencing minimal effects while others may face more noticeable alterations. It's important to monitor these changes and communicate any concerns with healthcare providers, as they can offer advice and support. Embracing a proactive approach can help in managing these side effects effectively.

If you are preparing for chemotherapy

Here are some questions you might want to ask your doctor or health professional regarding having CINV

  • Which chemo drugs will I be given?
  • How will the drugs be given to me?
  • How do these side effects compare with side effects of other treatments?
  • What can I do to get ready for the cancer treatment and decrease the chance of side effects?
  • Will I need to change my diet in any way?
  • Will I need to change my activities? 
  • How might I feel during and after the chemo treatments?
  • What can I do to help with nausea, vomiting, fatigue side effects?
  • How will this affect my daily life and work?

If you know someone about to have chemotherapy

It’s not easy seeing someone you know go through chemotherapy. It is often hard to know how to talk to and how support a chemo patient. Cancer gifts can ease this stress and show that you care. But there is no ‘one size fits all’ when it comes to the right thing to give. Providing nutrition tips for chemotherapy patients can be immensely helpful in maintaining their strength and overall well-being. It's essential to focus on nutrient-dense foods that can aid in recovery and help manage side effects. Additionally, staying hydrated and incorporating small, frequent meals can make a significant difference in their daily comfort. Chemotherapy preparation tips for patients can also include organizing their schedule to minimize stress and allow for rest. Creating a supportive environment can make a world of difference, as emotional well-being is just as important as physical health. Encourage loved ones to engage in light activities together, fostering a sense of normalcy amidst the challenges of treatment.
