Why does my Marfan syndrome teenager complain of being giddy?

Worth an Evaluation. Simpler to get them checked out for complications and sleep knowing they are ok. http://www.marfan.org/marfan/2493/.
Maybe medications. The beta-blocker medications used to control a marfan syndrome patient's blood pressure and heart rate can cause fatigue and lower blood pressure. A lower blood pressure can appear as lightheaded sensations or dizziness, especially when quickly standing up. If such a side effect seems to be happening, the patient's primary care doctor or cardiologist can re-evaluate.
