Don't take any diet pills, our transplanted kidney can't stand it. I don't know how long it's been since your transplant. Don't go to public places for half a year after renal transplantation, and be careful of infection. After kidney transplantation, with the recovery of the body and the role of hormones, your appetite will be particularly strong, followed by weight gain. To maintain your weight, you can eat less and more meals, eat 7 points full, and take a walk.
