For patients with cystinosis, common fruits in daily life can be consumed, such as apples, pears, kiwis, and saints’ fruits, which are rich in vitamins and their water, sugar, electrolytes, etc. After long-term consumption, they can supplement the trace elements and rich vitamin C required by the human body. However, for patients with cystitis, it is necessary to do a good job of regular re-examination, go to the hospital for regular bladder irrigation, and regular cystoscopy or ultrasound of the bladder and other tests to understand whether there is tumor metastasis or recurrence in the distant future. In daily diet, avoid spicy and stimulating diet, avoid contact with paint or benzene chemical products, reduce alcohol consumption and prohibit smoking in daily life, as long-term smoking and drinking will increase the probability of bladder cancer. In addition to diet, it is also necessary to have a regular work and rest schedule, avoid staying up late, and avoid holding urine for a long time. When there are infectious diseases in the urinary system, it is necessary to go to the hospital for examination and treatment as early as possible, to avoid the long delay which will lead to the damage of the bladder mucosa, and the probability of occurrence of tumors will be increased.
