Why Do I Have an Issue W/breathing After Tummy Tuck?

the biggest concern is always blood clots,,   your O2 level and  Co2 level can be checked.   as spiral cat scan considered.

if everything looks good..  it just may be your diaphragm still pushing up .

rule out  all of the serious issues

Shortness of breath is a danger sign after a tummy tuck.  This can sometimes be do to thromboembolism which can lead to pulmonary emboli or blood clots to the lungs.  This can cause shortness of breath and even  death.  Your doctor has performed the test to rule out this complication.

When the abdomen is tightened this will compress the inner organs which pushes up on the diaphragm.  This explains why it occurs when lying down sleeping.  Try elevating you back during sleep, this may help

Thank you for the question.

I'm glad that you have had the  most serious  complications such as pneumonia and pulmonary embolism ruled out.  Most likely you are dealing with difficulty breathing because of the increased intra-abdominal pressure after tummy tuck  putting pressure on the diaphragm (and limiting its excursion). You are probably also deconditioned after a period of   relative inactivity  after major surgery.

I would suggest continued follow-up with your operating surgeon.  I suspect your symptoms will continue to improve  as your  body adapts to the  anatomic changes.

I hope this helps.
