A cancer diagnosis can be overwhelming, and chemotherapy treatment can affect the body in many ways, including appetite changes, nausea, fatigue, mouth sores, taste changes, and weakened immunity. Maintaining proper nutrition during chemotherapy is extremely important because the right foods can help patients maintain strength, support recovery, improve immunity, and manage treatment-related side effects.
A well-balanced diet for chemotherapy patients should include adequate protein, healthy fats, vitamins, minerals, hydration, and easily digestible foods. Since every patient responds differently to treatment, nutritional needs may vary depending on the type of cancer, stage of treatment, side effects, and overall health condition.
At VS Hospitals, oncology specialists and diet experts often recommend smaller, nutrient-rich meals throughout the day instead of heavy meals to help patients maintain energy levels and reduce digestive discomfort during treatment.
