Two cigarettes a day can affect fracture recovery. Cigarettes contain a lot of nicotine and nicotine, which can stimulate the blood vessels and lead to vasoconstriction and spasm causing microcirculatory disorders, especially affecting the blood circulation to the fracture site. If the fracture site blood circulation is not good, the healing rate of the fracture will be slowed down, and in serious cases, the fracture may even have delayed healing or non-healing, so it is recommended that fracture patients quit smoking. In addition to smoking, fracture patients who do not have effective fixation, or who have excessive traction, lift heavy objects, do not perform normal rehabilitation exercises, or have unclean local hygiene can cause blood flow and nutrient transport to the fracture site to be affected, thus affecting fracture healing. During the fracture recovery period, functional exercises should be performed under the guidance of a doctor, and attention should be paid to avoid spicy and stimulating food, alcohol, coffee and carbonated beverages to prevent the local blood circulation from stimulating the fracture end and affecting the fracture healing. During this period, you should eat more food rich in calcium, protein and vitamins, such as lean meat, milk, soybean products, fruits and vegetables, etc. You should also supplement iron, zinc and other trace elements, and get more sunlight, which will be beneficial to the recovery of the fracture.
