The most intolerable thing for many male patients is that they must abstain from smoking after surgery! They especially do not understand why this is? Today, let’s find out why. Cigarettes contain more than 400 kinds of chemicals, 250 of which are harmful to the human body. Among them, nicotine, carbon monoxide, hydrocyanic acid, nitric oxide, these four substances are the most harmful to the human body. These harmful components make the blood vessels constrict, so that the body can not supply the wound recovery substances in time, resulting in the wound site oxygen supply is insufficient. They also prevent the regeneration of fibroblasts and epithelial cells and the synthesis of collagen, resulting in slow healing of the wound site. Although the male breast surgery incision is small, a strict smoking ban is necessary to ensure a scarless postoperative result. In addition, relevant research papers indicate that after surgery, smokers are three times more likely to have post-operative complications than non-smokers. This is the reason why smoking must be prohibited after male breast surgery.
