Hi and welcome to the forum! I am glad that I can help you.
You want to know what precautions you may take after kidney transplantation.
Transplantation is a medical procedure where a new healthy organ such as the kidneys is placed in the human body or when a damaged organ is replaced with another healthy one such as a heart, liver, etc. There are medical conditions that may appear in individuals after transplantation and those are: 1. rejection of the transplant or 2. graft versus host reaction. Both appear as a result of the activity of the immune system. Because after the transplantation the human immune system is deliberately suppressed in order to prevent these reactions, individuals are at risk of developing bacterial or viral infections.
According to the data that you described, you had kidney transplantation. Because there is a possibility of rejection of the transplant individuals should stay several weeks at home. There is no need of additional changes in the diet. You may consider consulting with your doctor or with the surgeon that did the transplantation about the time when you may start working or traveling. Pregnancy itself may cause the appearance of increased body temperature which might need to be medically treated, so it is advisable to avoid pregnancy during the recommended time to prevent hypertension. Also the medications used after the transplantation may cause damage to the fetus.
Please keep in mind that I provide medical information only. I am not able to diagnose medical conditions online. Please contact your doctor for further advice and information about post-transplantation recovery.
