What is Marfan syndrome?
Marfan syndrome is a disorder that affects the body's connective tissue. Connective tissue is the muscles, tendons, cartilage, and other parts that hold your bones, joints, organs, and tissues together. In Marfan syndrome, the connective tissue is weaker than normal so it stretches, bulges, or tears. Marfan syndrome can cause problems affecting the eyes, heart, and lungs.
Marfan syndrome runs in families.

How do doctors treat Marfan syndrome?
Doctors can’t cure Marfan syndrome. To treat some of the symptoms, they may:
-
Prescribe medicines that can make blood flow more gently and prevent problems with your aorta
-
Have children wear a back brace to treat abnormal curving of the spine (or sometimes do surgery to fix it)
-
Do heart surgery to fix any problems with your aorta or heart valves
-
Do eye surgery to fix any problems of your lenses or retinas
Doctors will check your bones, heart, and eyes each year to treat any complications of Marfan syndrome.
