Nausea In Cancer Therapy: Why Does It Occur And How To Manage It?

    Around 80% of the people receiving chemotherapy may experience nausea. It can cause malnutrition and dehydration. Let’s look into why nausea occurs in cancer treatments, anti-nausea medicines and essential tips to stop nausea.


    Why Does Nausea Occur During Cancer Therapy?


    Nausea is one of the very common side effects of cancer therapy. Cancer therapy is mainly focused on attacking the fast-growing cancer cells, but some healthy cells are also affected during the treatment and cause side effects. When certain parts of the brain or gastrointestinal tract are triggered during the cancer treatment, it can lead to nausea. 


    Treatment involving cancers of the brain, gastrointestinal tract, and liver are more likely to cause nausea. The other factors which cause nausea in cancer treatment are infection, pain, constipation, and other medications taken during the cancer treatment. Sometimes cancer itself (mainly brain or abdominal cancer) or stress caused by cancer and its therapy can cause nausea.


    Female patients and patients younger than fifty years are more likely to experience nausea in cancer treatment. A higher dose of the drug or radiation may make the symptom worse. Untreated nausea can keep you from getting the food and nutrients you need and end up in malnutrition and dehydration. Protein supplementation can help achieve good nutritional status in cancer patients experiencing nausea.
