Introduction
Patients undergoing chemotherapy generally have a complete blood count (CBC) test every 3 to 4 days. In addition to regular CBC monitoring every 3 to 4 days, patients should also pay attention to their daily diet. If normal diet cannot meet the body's nutritional needs, they should supplement with specific complete nutritional formulas to enhance physical strength and better cope with chemotherapy side effects.
Patients undergoing chemotherapy are generally advised to have a complete blood count (CBC) test every 3 to 4 days.
Chemotherapy drugs can damage not only tumor cells but also normal cells. Therefore, their use may lead to bone marrow suppression, resulting in significant decreases in white blood cell and platelet counts on CBC. This in turn may increase the risk of serious infections or bleeding. Hence, it is recommended that patients undergo a CBC test every 3–4 days during chemotherapy. If blood tests show a marked decline in blood parameters, patients should receive appropriate supportive treatments under medical supervision. In some cases, chemotherapy drugs may need to be discontinued temporarily.
In addition to regular CBC monitoring every 3 to 4 days, patients undergoing chemotherapy should pay attention to their daily diet. If normal dietary intake cannot meet nutritional needs, specific complete nutritional formulas should be supplemented to enhance physical strength and better tolerate chemotherapy side effects. Patients should avoid consuming high-temperature, fried, grilled, spicy, pickled, greasy, or hard foods. Instead, they are encouraged to eat fresh foods rich in high-quality protein, vitamins, and minerals, with diverse food choices to ensure balanced nutrition.
