Can I have areola reduction surgery after having pneumonia?

Dear Reliable191652,
it is hard to tell for sure without an examination. You need to be healthy prior to any elective procedure. You might need to get clearance from your pulmonologist prior to surgery. If you are considering surgery, I would suggest you consult a board-certified plastic surgeon. Only after a thorough examination, you will get more information and recommendations.

It is best that you are free from infection at the time of surgery. You will need to discuss your situation with your surgeon who will advise you when it is safe for you to proceed. If your pneumonia hasn't fully resolved you will likely need to postpone surgery until you are well.

No, with pneumonia, you must avoid general anesthesia for 6 weeks because your lungs will still be quite reactive. if you are doing this under local anesthesia, I suggest waiting 4 weeks to make sure all is cleared and you are not coughing.

You ask an interesting question, but the main concern is why are you asking an open form versus calling your surgeon and asking the person or doctor or surgeon whose performing the surgery with they think should be done.

You should tell your surgeon immediately that you have an active bacterial infection and pneumonia.
Surgeons don’t like surprises.
