Kidney transplant
The following lifestyle advice is usually recommended to help you stay healthy after a kidney transplant.
If you smoke, it's strongly recommended that you stop as soon as possible because smoking can reduce the life of your new kidney and can increase your risk of developing some types of cancer.
The NHS Smokefree website can provide support and advice to help you stop, and your GP can also recommend and prescribe treatments that can help. Read more about stopping smoking.
Most people are able to enjoy a much more varied diet after a kidney transplant, although you may be advised to avoid some foods after the operation until the kidney is working properly.
During the early stages after a transplant, while you're on higher doses of immunosuppressant medication (see below), you should avoid eating foods that carry a high risk of food poisoning, including:
Once your kidney is working properly and the best immunosuppressant dose for you has been identified, you'll usually be advised to follow a generally healthy diet, as this can reduce your risk of complications such as diabetes.

A healthy diet should include:
Avoid food that contains high levels of salt, as salt can cause high blood pressure, which can be dangerous for people with a kidney transplant. See facts about salt for more information and advice.
Once you've started to recover from the effects of surgery, you should try to do regular physical activity.
Adults should do at least 150 minutes (2 hours and 30 minutes) of moderate-intensity exercise every week. This includes any activity that increases your heart and breathing rate – it may make you sweat, but are still able to hold a normal conversation.
Examples include:
Choose physical activities that you enjoy, as you're more likely to continue doing them.
It's unrealistic to meet these exercise targets immediately if you have not exercised much in the past. You should aim to start gradually and then build on it.
If you're overweight or obese, you should try to achieve a healthy weight. This can be safely done through a combination of eating a healthy, calorie-controlled diet and regular exercise. Aim for a body mass index (BMI) of 18.5 to 25.

Regularly drinking alcohol above the maximum recommended limits can raise your blood pressure, which can be dangerous for people with a kidney transplant.
Read more about alcohol units and get tips on cutting down your alcohol consumption.
Alcohol is also high in calories, so you'll gain weight if you drink regularly. Being overweight will also increase your blood pressure. Read more about the calories in alcohol.
You should also avoid taking any illegal drugs after a kidney transplant, as they can damage your kidneys, cause a sudden rise in blood pressure and react unpredictably with your immunosuppressant medications.
Finally, always check with your care team before taking any medication, including over-the-counter medication and herbal remedies such as St John's wort. Some medications could be potentially harmful if you have had a kidney transplant and are taking immunosuppressant medication.
If you have a kidney transplant, you'll usually need to take immunosuppressant medications for the rest of your life to prevent your body's immune system from attacking the new kidney.
Widely used immunosuppressants include tacrolimus, ciclosporin, azathioprine, mycophenolate, prednisolone and sirolimus.
However, taking immunosuppressive medications on a long-term basis will weaken your immune system and make you more vulnerable to infections, so you'll need to take extra precautions against infection:
Make sure your vaccinations are up to date, although you won't be able to have any vaccines that contain live viruses, such as the measles, mumps and rubella (MMR) vaccine.
If you think you may have an infection, contact your GP or transplant centre for advice. Prompt treatment may be required to prevent serious complications developing.
Symptoms of infection can include:
A kidney transplant is the transfer of a healthy kidney from one person into the body of a person who has little or no kidney function. The main role of the kidneys is to filter waste products from the blood and convert them to urine.
Ideally, a kidney transplant should be performed when tests show that the extent of damage to your kidneys is so great that you'll need dialysis within the next six months. Most people with kidney failure need dialysis while they wait for a donated kidney to become available.
When a suitable donor kidney is found, the transplant centre will contact you. Staff at the centre will check you don't have any new medical problems and  then ask you to go to the centre. The kidney transplant procedure involves three main stages
Lifestyle advice is usually recommended to help you stay healthy after a kidney transplant. You should quit smoking, avoid eating foods that carry a high risk of food poisoning, start doing moderate-intensity exercise every week, etc
Although rates of serious complications have fallen sharply in the last few decades, kidney transplants like any other type of surgery are not risk-free. The risks of a kidney transplant include: risks related to the procedure itself, risks related to the use of immunosuppressant medications, etc.
