<s>[INST] Dear sir/madam, My son (Jay Kumar age-11 years) have a single kidney by birth. I come to know this is before 5 years. Now his heath is not good. Please let me know that which type of precution is required to maintain him healthy. Which type of exercise is better for him, which type of diet is good for him.. Please advise Thanking You, With Regards, Rajesh Kumar M:0000 [/INST] Hi, A person with a single kidney should lead a healthy and normal lifestyle. He should avoid getting overweight, avoid indiscriminate use of painkillers (NSAIDs) and avoid alternative medications as far as possible. No diet restrictions are required, but as I said, a good healthy diet should be stuck to. No exercises are specific to this condition. He doesn't need to avoid any exercise either. He should be active and once activity levels go down (after starting job etc.), a regular exercise program should be adhered to. Do check blood pressure, creatinine and urine (routine) once a year.
