\begin{abstract}
Hi Reddit, happy to be here. I'm a thoracic surgeon at NYP/Columbia
University specializing in disorders of the diaphragm. I'm the Surgical
Director of the Diaphragm Center, Lung Volume Reduction Program, and
Jo-Ann LeBuhn Center for Lung Diseases. The diaphragm is the primary
muscle of respiration, and disorders of the diaphragm can result in
significant impairment of breathing. These disorders are probably a bit
more common than you think. Most diaphragmic disorders are poorly
understood by the general medical community. Many people I treat have
been told ``there's nothing we can do'' before coming to see us. The
Diaphragm Center is the first of its kind in the world, and provides the
most advanced diagnostic and treatment strategies available for these
disorders. By gathering together some of the most experienced clinicians
in this field, we are able to offer the most comprehensive and advanced
care. Alright let's get to it, AMA! More about me Disorders of the
diaphragm include paralysis and weakness resulting in respiratory
insufficiency, diaphragmatic hernias resulting in abdominal organs
relocating into the chest, and lack of electrical stimulation to the
diaphragm resulting in respiratory failure. Edit: I'm here and ready to
roll! Proof Edit: It's about time I get back to work, but I'll be
checking in later today. Signing off for now. Thanks for the great
questions everyone!%
