Elevated heart rate - My heart rate is at 80 resting. I had tummy tuck surgery Thursday morning.

Thank you for sharing your question and congratulations on your surgery!  Without knowing your heart rate prior to surgery it is difficult to offer definite recommendations, as 80 beats per minute is not abnormal for many people.  Talk to your surgeon about your concerns, they can provide you with reassurance.

An elevated heart rate soon after surgery often is due to pain. However, there are other reasons such as dehydration, fever, hypovolemia (loss of blood at time of surgery or soon after), pulmonary embolism, Urinary tract infection, etc. you can see that some reasons are much more serious than other reasons. Therefore you must see your surgeon and let them know exactly what is going on so they can properly evaluate and treat you. 

We do not know what your base heart rate was before tummy tuck, though an elevated heart rate can mean many things such as fever, dehydration, or even can be a first sign of pulmonary embolus or PE. If you think you are at all unwell then the right thing to do is call your surgeon immediately.
