Try not to smoke after a fracture as this may have an effect on the healing of the fracture. Smoking is very harmful to people with fractures especially after having surgery. Since tobacco contains nicotine, a substance that is detrimental to the healing of the incision, the process of smoking may affect the healing of the incision. Nicotine may also lead to platelet aggregation and vasoconstriction, affecting local blood flow, so smoking after a fracture may lead to delayed healing or even the possibility of non-healing. Smoking after fracture is also not recommended for young people, and in the case of older people, who themselves suffer from more underlying diseases such as diabetes and coagulation abnormalities. It is even more important not to smoke, so as not to cause adverse consequences to the body.
