Like all malignant tumors, patients with lymphoma should pay more attention to many details of their lives during and after the follow-up period of treatment. Some patients who have lymphoma are worried all the time and dare not do this or that, and even lie in bed at home all the time, thinking they have become a “waste”; some patients boast that they are “not afraid of a tumor” and still eat and drink, smoke and drink. In fact, these two extremes are very detrimental to the treatment and recovery of the disease. The World Health Organization has proposed four cornerstones of health, namely: reasonable diet, moderate exercise, smoking and alcohol cessation, and psychological balance. These 16 words are not only applicable to healthy people, but also to lymphoma patients. One of the most common questions that lymphoma patients and their families ask their doctors is “What should I pay attention to in my diet? What are the best supplements to take? What should I not eat?” The first dietary recommendation for lymphoma patients is hygiene and cleanliness. Due to the disease itself and the influence of chemotherapy and other drugs, lymphoma patients are more or less immunocompromised, and the mucosal barrier of the mouth and even the whole digestive tract is often damaged, so meals should be cooked thoroughly and eaten as soon as possible in a fresh state, avoiding food that is out of date and spoiled, food from unknown sources or food purchased from hawkers; for fresh fruits, try to choose those that can be peeled or peeled, such as oranges and bananas, and avoid strawberries and grapes. For fresh fruits, try to choose those that can be peeled or peeled, such as oranges, bananas, etc., and avoid strawberries, grapes, etc. that are not easily washed. Secondly, the nutritional elements are balanced. After suffering from lymphoma, it is not necessary to eat “delicacies” such as turtle, loach and sea cucumber every day, but we should still refer to the guiding principles of the dietary pyramid, mainly carbohydrates, fruits and vegetables, dietary fiber and high quality protein, avoid excessive fat and salt intake, and avoid the intake of raw, cold, spicy and other stimulating foods. Avoid excessive intake of fat and salt, and avoid stimulating foods such as cold and spicy foods. The third is to avoid taking so-called supplements and health products, which do not have the magical efficacy advertised, but may increase the burden on the gastrointestinal tract or have potential toxicity to liver and kidney function. In addition to diet, lymphoma patients should pay more attention to their details in other aspects of life, such as personal hygiene and protection: pay attention to less visits to public places and prevention of infection; pay attention to reasonable rest, avoid overexertion, and avoid staying up late; pay attention to oral and perianal cleanliness; and pay attention to being alert to any subtle changes in their bodies. Patients with lymphoma can do some household activities and even light physical exercise such as walking and cycling if their blood count is basically normal and they are not in obvious discomfort during the interval between treatments and after the treatment. For patients with previous smoking and drinking habits, the author advises strict abstinence from smoking and drinking, both during and after treatment, to avoid adding to the disease. Patients with lymphoma will be overwhelmed when they are first diagnosed, but as treatment progresses, they should gradually return to society, communicate and cooperate with your family and medical staff, and participate in social activities as much as they can, so that everyone can see a healthy you again, both physically and mentally.
