Smoking and Wound Healing

Smoking and Wound Healing

How Does Smoking Affect Wound Healing?

Cigarettes contain nicotine. Nicotine causes your arteries to become narrow. It can also cause your arteries to go into spasm. When this happens, the oxygen and nutrients carried in your blood cannot get to your wound. Oxygen and nutrients are needed for your wound to heal. A wound that does not get enough oxygen and nutrients may result in a wound that does not heal.

How Else Does Nicotine Affect the Body?

  • Tobacco smoke leads to many types of cancers.
  • Smoking increases your heart beat and blood pressure. It strains your heart and blood vessels.
  • This can cause heart attacks, strokes or, limb amputations.
  • Smoking makes a tar like substance that coats your lungs and may cause lung cancer.
  • Smoking leads to emphysema and chronic bronchitis. This causes the lung and heart to fail.
  • Smoking harms nearly every organ of the body.
  • Smoking accounts for 438,000 deaths or 1 in 5 deaths in the U.S. every year.
