Hello, Dilysis in Diabetes is generally occur when patient developed nephroapyhy. In nephroathy, when developed Chronic kidney disease(CKD). In your description, it s not clear wether patient is suffering from acute Kidney injury(AKI) or CKD. Generally in AKI, patient needs dialysis for short duration of time unless creatinine level get down to normal or stable in medication without any symptoms. But in CKD, patient needs dialysis frequently depends on severity of disease for a longer time or for a life time. In that case, one should be think about transplant option depends on disease and another high risk factor. In your case, if she developed CKD then she will need dialysis frequently for life time and require transplantation if possible. Meanwhile at present case, if doctor said more dialysis she needed then definitely she will go for more dialysis and afterward if general condition becomes good then she can travel with medications. It will be no problem for her. Thank you
