Cardia cancer patients should eat light, easy-to-digest and nutritious food during chemotherapy, such as fish soup, rib soup, egg custard and so on. Cardia cancer patients may have gastrointestinal reactions such as nausea and vomiting during chemotherapy, so they can eat fluids or semi-fluids and other soft and easy-to-digest foods, such as rice soup, rotten noodles and so on. As the gastrointestinal function slowly recovers, you can eat nutritious food such as meat, milk, eggs, etc., and fresh vegetables and fruits rich in vitamins, such as celery, apple, banana and orange. Cardia cancer patients should avoid smoking and alcohol, usually pay attention to small meals, diversified diet, ensure balanced nutrition, keep a pleasant mood, regular review, and seek medical treatment in time if obstruction or bleeding occurs.
