Cold symptoms 4 days before surgery, will I be able to have surgery?

If your surgeon says it’s okay to proceed with surgery, then it should be fine. Normally, rescheduling the surgery to when you’re in better condition would be ideal. It would also improve the whole experience, since you wouldn’t have to deal with your symptoms in addition to recovering from your surgery.

While feeling less than completely healthy at the time of your abdominoplasty is suboptimal, it may be reasonable to proceed if your symptoms are mild. It's smart to keep in contact with your surgeon so that he/she can help make the best decision with regards to proceeding or postponing your procedure. Fevers and sputum production would be reasons to postpone the date of your surgery. Hope you feel better soon. 

Thank you for your question. If in the unfortunate circumstance that you get sick before your surgery, you may have postpone your surgery until you are better again. If you are feeling sick, I would discuss with your surgeon who may help you decide depending on your individual symptoms.

        If no fever or chills, this may be reasonable.  However, with tummy tuck, coughing or sneezing may hurt more than after other procedures, where plication is not performed.

Sounds like your surgeons office is advising you correctly. It is good that you let them know in advance, they do not want you to have any complications.  Hopefully it is only allergies and you will be able to proceed with your surgery, but if it needs to be rescheduled be grateful that your safety comes first. Good luck.
