During my hair transplant I coughed loudly a couple of times. Will that make my grafts pop out?

Any large sudden or rough motions can damage a transplant in the first 7 days. It is good to try to take it easy and maintain close follow up with your doctor if this happens. 

Can coughing cause grafts to pop out of the incisions? Sure. Is it likely that your coughing caused a problem. No. But run it by your surgeon to get the final answer as to what specifically happened during your surgery. Here are some general points:If the force of coughing caused a graft to pop out during a procedure, the doctor and team would likely notice and fix the situationCoughing can cause grafts to pop but it is pretty rareThe more coughing the more likely for popping. A few times is unlikely to have any consequenceCoughing, sneezing (and vomiting) after the patient goes goes home is different because nobody can see if popping occurred. In general, coughing that causes graft popping is rare. Coughing sufficient to cause problems while a patient is still at the clinic is even more rare. But check with your team to be sure
