Life after an organ transplant: Learn about immunosuppression
Table of Contents ▾

Life after an organ transplant is like a new birth. But with this new life comes a number of challenges. You might think, "Now I have a new organ, the problem is solved." But the truth is a little more complicated than that. Our body's defense system, the immune system , is very good at recognizing and attacking foreign invaders like germs and bacteria . But there's a little problem. Sometimes this defense system sees the new organ that brought you life as an "enemy." So it starts attacking it too. We call this " organ rejection ."

Why are these immunosuppressants necessary?

Imagine that your body has some very smart guards. They are always on the lookout for an enemy. When these guards see the newly transplanted organ, they get a little nervous, thinking it's an enemy and getting ready to attack. This is where immunosuppressant drugs come in handy.

These drugs are used to calm those nervous security guards down a bit. It's like telling them, "Don't worry, this is one of ours." Then the body can live with the new organ without any problems, in peace.

But here's the most important thing we need to understand. That is, these medications weaken the entire immune system a little. That means, if a real enemy, a germ, comes along, the ability to fight it off is also a little less. So, the chances of infections are higher.

Simply put, life after an organ transplant is like walking a tightrope. On the one hand, you need to stop the organ from rejecting you, and on the other hand, you need to protect yourself from infections. The challenge is to strike the right balance between the two. But don't worry, doctors these days are very good at maintaining this balance.

What precautions should be taken in the initial period after surgery?

The first few weeks and months after an organ transplant are very important. We call this the "Induction phase." During this time, you will be given medications that suppress your immune system.The dose is a bit high. So you need to be very careful to avoid infections. Here are some things you can do for that.

Sector to be careful of Do's and don'ts
Personal hygiene Wash your hands thoroughly with soap and water often, especially before eating and after using the toilet. Brush your teeth daily. Don't ignore even a small cut or scrape. Clean it thoroughly, apply medicine, and apply a plaster.
Social interaction Stay away from people who have colds and flu. Avoid going to crowded places (e.g. shopping malls, movie theaters, public transportation) as much as possible for the first few months.
Home environment Don't go out to pick up pet waste (dogs, cats). Assign that task to someone else in the house. Stop doing things like gardening, digging, and planting trees for the first few months. The soil can contain dangerous bacteria.
Sexual health Practice safe sex. Sexually transmitted diseases (such as herpes) can be very dangerous for you. Talk to your doctor about this and get advice.

Precautions to be taken throughout life

Six months to a year after surgery, your doctor will gradually reduce your medication dose. Then you will enter the "Maintenance Phase." During this time, your risk of infection is lower than before. So you can relax a bit. But you should continue to practice good habits like washing your hands and staying away from sick people.

At some point your body will reject the new organ (If organ rejection occurs, your doctor may need to change the medication or increase the dose again. If that happens, you will need to be very careful again, just like before.

Why is it so important to take your medication exactly as prescribed?

The most important and most important thing to succeed in life after an organ transplant is to take your medications at the right time, in the right dosage, and without missing a day. It's okay to think of this as a matter of life and death. You may have to take 6, 12, or even more medications a day. It may seem a little difficult. But your new life depends on those medications.

Here are some tips to make taking your medication easier:

  • Follow your doctor's instructions exactly. Take your medicine exactly as your doctor tells you, at exactly the time.
  • Use a pillbox that can hold your medication for the week. That way, you won't have to worry about whether you've taken your medication or not.
  • Set an alarm or timer on your phone.
  • Let your family know about your medication times. They can remind you.
  • Always store medication in a cool, dry place, out of the reach of small children and pets .
  • Write a list of all the medications you take and keep it in a visible place.
  • If you miss a dose, never take a double dose to make up for the missed dose. Call your doctor immediately for advice.
  • Don't wait until you're almost out of medicine, call the pharmacy ahead of time and get the next dose.
  • If certain medications cause stomach upset, ask your doctor and take the medication with food.
  • Associate the time you take your medication with other activities you do during the day, such as brushing your teeth, eating, or going to bed. That way, you'll be less likely to forget.
  • Do not stop taking medication for any reason without your doctor's approval.
