When the Body Revolts: Understanding Nausea and Vomiting During Cancer Treatment

Nausea and vomiting are among the most commonly reported experiences during cancer treatment. Whether you are going through chemotherapy, radiotherapy, immunotherapy, or recovering from surgery, that persistent wave of queasiness — or the sudden urgency of vomiting — can feel relentless, exhausting, and deeply demoralising. It can make eating feel impossible, rest feel elusive, and the ordinary business of a day feel like an enormous mountain to climb.

If you are living through this right now, you are not alone. And while your medical team is your most important ally in managing treatment-related nausea and vomiting, many people find that complementary and holistic approaches offer an additional layer of support — helping to ease symptoms, restore a sense of agency, and bring the nervous system back to a calmer place.

This article explores some of the holistic practices that people undergoing cancer treatment have found helpful when navigating nausea. It is not a replacement for medical guidance — it is an invitation to explore what else might be possible alongside it.

Why Does Cancer Treatment Cause Nausea?

It helps to understand a little about what is happening in the body. Chemotherapy-induced nausea and vomiting (often referred to as CINV) occurs because many chemotherapy drugs are recognised by the body as toxic substances. The gut and brain communicate rapidly through the vagus nerve, and certain chemotherapy agents trigger the release of serotonin in the small intestine, which activates the vomiting centre in the brain.

Radiotherapy to the abdomen, pelvis, or brain can also cause nausea, as can some targeted therapies and immunotherapy drugs. Post-surgical nausea is another common experience, often linked to anaesthesia and opioid pain management.

There is also an anticipatory component. After repeated episodes of nausea, the nervous system can begin to associate the treatment environment — the smell of the clinic, the drive there, even the thought of it — with nausea itself. This is a well-recognised phenomenon and it underscores something important: the mind and body are not separate when it comes to nausea. Which is why holistic approaches that address both can matter so much.

What Holistic Support Might Look Like

There is no single approach that works for everyone. Nausea is deeply individual — its triggers, its rhythms, and what soothes it vary from person to person. What follows is an overview of the holistic modalities that have the most evidence or anecdotal support in the context of treatment-related nausea and vomiting. Always share these with your oncology team before beginning anything new.

Acupuncture and Acupressure

Acupuncture is one of the most researched complementary therapies in the context of chemotherapy-induced nausea and vomiting. It works within the framework of traditional Chinese medicine, using fine needles at specific points on the body to regulate energy flow and support the body's own balancing mechanisms.

A specific acupressure point — P6, also known as Neiguan, located on the inner wrist — has been studied extensively. Stimulating this point, either with needles or with gentle finger pressure, has been found in multiple studies to reduce the severity and frequency of nausea. Acupressure wristbands designed for travel sickness apply constant pressure to this point and are widely used by people in treatment.

If you are curious about acupuncture, Sissoo's body therapies include practitioners who work with this tradition and may be able to support you.

Ginger: Nature's Quiet Ally

Ginger has been used for centuries across many cultures as a remedy for nausea and digestive discomfort. Modern research supports its traditional use — ginger contains bioactive compounds, particularly gingerols and shogaols, which appear to influence the digestive tract and serotonin receptors involved in nausea signalling.

It can be taken as a tea (fresh root steeped in hot water), in capsule form, as ginger lozenges, or crystallised ginger. Some people find even smelling fresh ginger helpful during acute nausea episodes. That said, ginger supplementation should be discussed with your oncology team, particularly if you are taking blood-thinning medications, as it can have mild anticoagulant effects.

Exploring how nutrition and nature's medicine can support your body during treatment is something Sissoo's nutrition and nature's medicine practitioners can help with — offering guidance that is sensitive to your treatment protocol and individual needs.

Aromatherapy

The sense of smell has a direct line to the limbic system — the brain's emotional and memory centre — which is why scent can be so powerfully evocative, and also why it can either trigger or ease nausea. Aromatherapy uses essential oils to support the nervous system and overall wellbeing.

Peppermint oil is perhaps the most cited in relation to nausea — inhaling its scent (from a tissue, a diffuser, or simply a drop on the wrist) is something many people in treatment find genuinely soothing. Lemon, spearmint, and lavender are also frequently mentioned. Some clinical trials have explored peppermint and spearmint aromatherapy specifically in chemotherapy-induced nausea with encouraging results.

Aromatherapy can be offered as part of a bodywork session or as a standalone guidance session. Sissoo's body therapies page is a good place to explore practitioners in this space.

Mindfulness and Meditation

The relationship between the mind and nausea is significant. Anxiety, anticipatory nausea, and the cumulative emotional weight of treatment can all amplify physical symptoms. Mindfulness — the practice of bringing gentle, non-judgmental attention to the present moment — can help interrupt some of these feedback loops.

Mindfulness-based stress reduction (MBSR) and guided meditation have both been studied in cancer populations, with evidence suggesting they can reduce anxiety, improve quality of life, and may help with symptom perception, including nausea. Body scan meditations, breath-focused practices, and visualisation can all offer moments of relief.

When nausea is severe, sitting still and meditating may feel impossible — and that is completely understandable. Even a few conscious breaths, a grounding practice, or a short body awareness exercise can be enough. The goal is not perfection; it is presence.

Sissoo's meditation offerings include practitioners experienced in supporting people through difficult health journeys, including guided sessions that can be done lying down or in any position that feels manageable.

Breathwork and the Nervous System

Nausea often has a nervous system component — when we are anxious or in fight-or-flight mode, digestion slows and nausea can worsen. Slow, diaphragmatic breathing activates the parasympathetic nervous system (the rest-and-digest response), which can reduce nausea intensity.

A simple technique: inhale slowly through the nose for four counts, hold gently for two, exhale slowly through the mouth for six to eight counts. Repeating this for just a few minutes can shift the nervous system into a calmer state. Some people find this especially useful before treatment sessions to help with anticipatory nausea.

Practitioners offering yoga and movement therapy on Sissoo may also incorporate breathwork practices that are gentle enough to use during treatment, including restorative yoga and yin yoga which focus on stillness, breath, and deep relaxation rather than physical exertion.

Reflexology

Reflexology works with the principle that specific points on the feet (and sometimes hands and ears) correspond to organs and systems throughout the body. A trained reflexologist applies gentle pressure to these points in a way that is profoundly relaxing and may help regulate the body's responses.

Some research into reflexology during cancer treatment has shown benefits for anxiety, fatigue, and quality of life. While evidence specifically for nausea is still emerging, many people report that the deep relaxation reflexology induces helps ease their symptoms. It is also a therapy that many people find deeply comforting during a time when their body may feel under assault — a reminder that touch can be nurturing and kind.

Reiki and Energy Medicine

Reiki is a gentle, non-invasive energy healing practice in which a practitioner channels healing energy through light touch or near-the-body hand positions. It is deeply relaxing and is offered in some NHS and private oncology units as a complementary support.

People undergoing cancer treatment often describe reiki sessions as profoundly calming — a space where they can simply be, without being poked or prodded, where their body is held with gentleness. This kind of deep rest can support the nervous system in ways that may indirectly ease nausea, particularly where anxiety and tension are contributing factors.

Sissoo's energy medicine practitioners offer reiki and other supportive modalities that can be received in person or, in some cases, remotely.

The Emotional Layer: Speaking and Listening Therapies

It would be incomplete to address nausea during cancer treatment without acknowledging the emotional weight that sits underneath it. Fear, grief, anger, exhaustion — these emotions are entirely natural responses to a cancer diagnosis and its treatment. And when emotions go unexpressed or unprocessed, they can deepen physical symptoms.

Counselling, integrative therapy, or even supportive coaching can create a space to voice what is hard to say elsewhere. The act of being truly heard — without someone trying to fix things or find a silver lining — can be profoundly relieving.

Practical Day-to-Day Considerations

Alongside holistic therapies, there are some gentle, practical approaches that many people in treatment find helpful for managing nausea on a daily basis. These are not prescriptions — simply observations drawn from lived experience and supportive care guidance:

• Eat small amounts frequently rather than large meals — an empty stomach can worsen nausea
• Choose cool or room-temperature foods — strong smells from hot food can trigger nausea
• Stay hydrated in small, frequent sips — ice chips and cold water can sometimes be easier to tolerate than warm drinks
• Avoid lying down immediately after eating — a short, gentle sit-upright period can help
• Identify and reduce triggers — certain smells, environments, or even sounds may be linked to nausea episodes
• Rest, but gently move — a slow, short walk in fresh air is something many people find helpful when nausea is mild
• Wear loose, comfortable clothing that does not put pressure on the abdomen
• Talk to your team if nausea is severe or preventing you from eating — anti-emetic medications are highly effective and you should not feel you need to manage without them

You Do Not Have to Navigate This Alone

One of the most isolating aspects of treatment-related nausea is how invisible it often is. You may look relatively well to the outside world, while inside you are navigating something that feels relentless and depleting. The Sissoo community exists precisely for moments like this — a space where you can find practitioners who understand the complexity of illness, who work with both the body and the whole person, and who meet you with care rather than clinical distance.

Whether you are just beginning treatment, in the thick of it, or recovering, there may be something here that helps. Even a single session of something gentle — a meditation, a reflexology treatment, a conversation — can shift something. Not because it is a cure, but because being cared for matters. Because your comfort matters. Because you matter.
