Hi, There are guidelines for live kidney donors to be followed for a successful transplantation to keep the chances of rejection minimum. For those donors with high cholesterol, it iz said that various forms of dyslipidemia have been associated with decreased kidney function in the general population and with faster rates of progression in those patients who have chronic renal disease. High cholesterol levels or dyslipidemia should be included along with other risk factors in donor risk assessment, but dyslipidemia alone does not exclude kidney donation. You can still donate a kidney to your father after getting a detailed evaluation done by a the group of doctors in the transplantation team.
