Members shared their personal experiences with thymectomy surgery in response to someone asking whether medication can shrink the thymus gland, with several noting that while no medication was mentioned, surgical removal helped reduce their myasthenia gravis symptoms significantly. Several members described how the thymus produces proteins that interfere with nerve-muscle communication in MG, and removal can improve symptom control, with one member highlighting that modern robotic surgery is far less invasive than older open-sternum procedures and leaves minimal scarring with faster recovery. A recurring theme was the deeply personal nature of the decision, with members acknowledging that surgery may not be right for everyone, especially those concerned about surgical risks, while offering hope and support to those navigating their treatment options.

The robotic surgery is the best. Not very invasive at all. I've had some other surgeries before, but this one barely left a scar for me, and I don't think I took any pain meds either!

I don't know why my thymus began to shrink. It went from 6cm to 2cm and then began to overreact again. My neurosurgeon removed my thymus in October 2025 my symptoms have been very minimal since
I was told I will be monitored for a year before they can let me know if I am in remission or not.

Hi Kim!
I don't know if there is a medication that shrinks your thymus gland.
I have read years ago that your thyme gets smaller as you go through puberty and turns into a small fatty deposit.
And my understanding is that people with myasthenia that may not be the case.
I was told many years ago that the thymus produces a protein along with all of your other organs, but the thymus produces more than any of the others and so that's why we have it removed. It was explained to me that it's like a car battery. If you don't get a good connection, you can't start your car so you fix the cables and the car will start.
So removing the protein that hinders the connection and the medication that you take will help. Not sure if really this is true but this is what was told to me 30 years ago and over research. I have read something to that effect. When I had my thymectomy they cut my sternum open and from what I understand now they may not have to do that less evasive.
Do a lot of research and good luck with your journey 😀

Are there medications available to shrink the thymus gland?

Unfortunately, there aren't medications specifically designed to shrink the thymus gland in myasthenia gravis. The primary approach for addressing thymus gland issues is surgical removal through a procedure called thymectomy.

The thymus gland plays a significant role in MG by producing harmful antibodies that block signals between nerves and muscles. When the thymus is overactive or enlarged, removing it surgically can help calm down the overactive immune system.

However, medications do play an important role in managing MG overall:

* Immunosuppressants like corticosteroids and azathioprine reduce immune system activity
* Newer biological therapies target specific parts of the immune system
* These medications help control symptoms but don't specifically shrink the thymus

In some cases, your doctor may recommend plasma exchange or intravenous immunoglobulin (IVIG) before a thymectomy to help strengthen muscles and lower surgical risks, but these treatments don't shrink the thymus either.

If you're concerned about your thymus gland, it's worth discussing thymectomy with your healthcare provider. About 70 percent of people who undergo this surgery see improvement in their symptoms, and 30 to 40 percent achieve full remission.
