The immune system is your body’s natural defence mechanism. The immune system will mount a defence response against anything foreign, including bacteria and organisms that cause infection. The immune system will also recognise the cells of the transplanted liver as foreign and will try to fight them. Therefore following your liver transplant, you will be prescribed specific drugs which stop the immune system from rejecting the new liver. These drugs are known as immunosuppressants and you will need to take them daily for the rest of your life. The daily dosage is cautiously determined by your transplant physician, and you can’t change it without consultation, otherwise your body can reject your new liver.
It is important to note though that these immunosuppressant drugs will increase your susceptibility to infections, especially in the first few months after the transplant when the need for these drugs is at its highest. Your risk decreases gradually as the drug doses are reduced in the following months, but you need to be vigilant at all times and avoid contact with individuals with infection, and refrain from eating any raw foods. If you experience any signs of infection, you need to be treated promptly.
