The first few weeks after a kidney transplant are crucial because the chances of rejection are high in the initial days, till the body accepts the foreign organ and the new kidney starts functioning properly. It is thus essential to visit your hospital and see your doctor regularly during the first few months, to check your kidney functioning. Certain anti-rejection drugs are also prescribed to ensure that that kidney is not rejected by your body. These drugs work by weakening the "army" cells that attack any foreign object that is introduced in the body, in this case the new kidney. A transplanted kidney normally lasts for around 8 years though a case of 35 years has also been reported once.
In order to make your kidney last longer, it is a must to take your medication regularly and never stop taking them. Apart from this, stick to your scheduled hospital visits and let your doctor know of any problems or infections. It is also important to lead a healthy lifestyle, avoid smoking and maintain a balanced diet. Your diet should include fresh fruits and vegetables, grains, milk, dairy products as well as some meat. Ensure that your diet is a low-fat diet which does not increase your cholesterol levels. Also remember that your appetite will increase after the transplant, so watch your weight!
Around 2 months after a kidney transplant, you can slowly resume your normal lifestyle. Avoid lifting heavy objects up to three months after your operation. Regular exercise is recommended to regain your strength so you should walk, swim or play some light sports like tennis. Avoid rough sports like football or hockey in which chances of an injury to the lower abdomen, where your kidney is found, are higher. Do not over-do the exercise and exert yourself beyond your threshold level. It is important to stay healthy and fit to ensure that your new kidney has a long and healthy life.
