Relief of side effects of chemotherapy for stomach cancer can be supplemented with treatments such as antiemetic, hydration, gastric protection, and herbal modification. Common side effects of chemotherapy for stomach cancer are gastrointestinal reactions such as nausea and vomiting, abdominal distension and loss of appetite. If chemotherapy treatment is supplemented with antiemetic (e.g. metoclopramide), hydration (vitamin B6 injection + 0.9% sodium chloride injection) and gastric protection (e.g. omeprazole), most of the people can be asymptomatic or reduce the symptoms or the symptoms can be relieved within a few days. If a small number of people have poor appetite after chemotherapy, they can ask professional Chinese medicine practitioners to take traditional Chinese medicines to regulate the spleen, stomach and whole body condition, and gradually resume eating and drinking. There are many kinds of side effects of chemotherapy for stomach cancer, so inform your doctor in time if you have any discomfort and actively cooperate with the treatment. Note: All the above medicines should be used under doctor’s guidance.
