Is weightlifting safe for a person with Marfan syndrome?

Question

Hello doctor,

I am 18 years old. A few years ago, I was diagnosed with Marfan syndrome. So far, my life has been fine, and I believe my condition is relatively mild. However, my aorta is enlarged. The last time it was checked, the measurement was 44 mm, which was unchanged from the previous year.

I have always wanted to work out, not professionally, but simply to build a good physique. However, because of Marfan syndrome, I have certain restrictions, which I understand and accept.

My concern is that I received different advice from different doctors. A doctor told me not to lift more than 11 pounds, whereas another doctor whom I consulted online told me that I could lift up to 33 pounds.

I would like to know what level of weightlifting is considered safe for someone in my situation so that I can pursue this goal responsibly. Receiving such different recommendations has left me feeling uncertain about what I can and cannot do safely.

Kindly help.

Hello,

Welcome to icliniq.com.

I read your query and understood your concern.

With Marfan syndrome and an enlarged aortic root measuring 44 mm, it is very important to follow the advice of the cardiologist who is regularly monitoring your aorta.

In general, people with Marfan syndrome are advised to avoid heavy weightlifting, maximal-effort lifts, straining, and breath-holding Valsalva maneuver, as these can cause sudden spikes in blood pressure that increase stress on the aorta.

Rather than focusing on a specific weight limit such as 11 to 33 pounds, current recommendations usually emphasize using light-to-moderate resistance with higher repetitions, stopping well before exhaustion, and avoiding exercises that require straining.

Since your aorta is already enlarged, it would be safest to discuss a structured exercise plan with your cardiologist, ideally one familiar with Marfan syndrome. The acceptable level of resistance depends on your body size, aortic measurements, rate of aortic enlargement, medications, and overall cardiovascular status.

Building a good physique is often still possible through carefully supervised resistance training, bodyweight exercises, and aerobic activity. However, heavy lifting and competitive strength training are generally not recommended.

A repeat evaluation with your cardiologist before increasing your training intensity would be the safest approach.
