Living With It

Living with Marfan syndrome

Treating and living with Marfan syndrome, and its complications, is a lifelong process. However, treatment makes it possible for people with the disorder to have long, productive lives. The following tips can help you manage the disorder:

  • Ask your doctors how often you should schedule follow-up visits. The visits may include regular eye exams, image tests to check for heart and lung problems, and an evaluation of your skeleton and growth.
  • Reach out for support. Talk to your family and friends about the disorder and your feelings. Consider joining a community or online support group.
  • Seek counseling or talk to a health care professional if you feel depressed or anxious about Marfan syndrome and its effects on your body. 
  • Eat a healthy well-balanced diet rich in fruits, vegetables, and whole grains.
  • Consider wearing medical identification to notify providers about your condition during an emergency.
  • If you smoke, quit. Smoking can have a negative impact on both your bone and lung health.

Women with Marfan syndrome can have healthy pregnancies. However, the pregnancy is high risk because it can add stress on the heart. If you are thinking about getting pregnant, talk to your doctor. Planning helps doctors treat problems prior to the pregnancy to keep both the mother and baby healthy.
