Omeprazole can be taken by stomach cancer patients with increased gastric acid to inhibit the secretion of gastric acid and improve the clinical symptoms such as abdominal distension, abdominal pain, acid reflux, etc. Therefore, omeprazole can only inhibit the symptoms due to gastric cancer, but not inhibit the spread of cancer cells, and can not be a radical cure for cancer. Early stage stomach cancer patients can be treated by surgery and chemotherapy, and with the use of Chinese herbs, the growth of cancer cells can be effectively inhibited, and the immunity of the body can also be strengthened. Stomach cancer patients need to pay extra attention to their diet, eat light and easy-to-digest food, and avoid cold, spicy, irritating, hard and indigestible food. Patients can also take appropriate amount of vitamins to improve the immunity of the body, so as to avoid infection and other serious complications caused by virus invasion.
