Smoking and Wound Healing:
A Guide for Surgical and Burn Patients

Smoking can cause problems with wound healing. There are many ways you can help your body
heal faster.

What is the function of our skin?

Our skin system is made of 3 layers, the epidermis, dermis, and subcutaneous layer. Hair, nails, and
glands are included in the skin system. The skin is the largest organ of the body. It acts as a giant
covering that protects the inside of our bodies from infection. A picture of what our skin looks like
is shown below.

What happens when my skin has a wound?

Wounds result from many things such as burns, surgery, scraping your knee, or infections. No
matter how big or small your wound is your body follows a similar process to help it heal. When a
wound occurs, the immune system sends out many healing factors through the blood vessels to the
wound to help it heal. Oxygen we breath is also sent to the wound through our blood vessels to help
the wound heal. When the wound healing process is complete, the new skin and/or scar tissue
functions as a new covering to protect us from future injuries.

How does smoking affect my skin and wound healing?

Smoking causes blood vessels to become smaller. The smaller vessels have a hard time carrying
oxygen, nutrients, and healing factors to the wound. This can cause the wound healing process to
take longer.

Carbon monoxide is a poison from smoking that enters your blood cells. This poison lowers the
level of oxygen in your blood. Oxygen is vital to your healing. It only takes 3 full days of not
smoking to get rid of all the carbon monoxide in your blood. It is vital to quit smoking for at least 3
days before your surgery so the oxygen can build back up in your blood stream.

What if I only smoke every once in a while or only smoke cigars?

Studies have shown that any amount of smoking can delay the wound healing process, even if you
only smoke once in a while. Cigars also prevent wound healing in the same way.

Won’t my wound(s) heal anyway?

Yes, your wound(s) may still heal, but there are many other reasons why you should stop smoking.
Smoking can cause many of the problems listed below.

 Infection of your wound.
 Longer and more expensive hospital stay.
 If you have received a skin graft, it has a greater chance of not attaching as it should or
 Blood clots may form near the wound.
 Stitches may come apart, causing scarring.
 You are more likely to catch a cold or pneumonia due to more mucus in your lungs.
 Decreased Vitamin C levels. Vitamin C is needed to help your skin heal.

What can I do to help my wound(s) heal?
Eat right and drink lots of fluids. Wound healing takes a lot of energy. It is a good idea to increase
the amount of protein, calories, and Vitamin C you eat. Meats, nuts, beans and dairy products are
great sources of protein. Citrus fruits and green leafy vegetables are sources of Vitamin C. Try to
drink eight (8 oz.) glasses of water a day, and avoid drinks with caffeine. Caffeine causes the body
to lose water. When the body does not have enough water, your skin can become dry, and your
wound will not heal as well.

Know and look for signs and symptoms of infection.
Contact your doctor if you have these symptoms.
 Increased redness (over 1 inch in width) and swelling around the skin graft.
 Foul smelling drainage or pus from the skin graft.
 Flu-like symptoms (fever, chills, nausea or vomiting, muscle aches) and/or increased

Stay as active as possible. Exercise will help keep you healthy. It will also help your immune
system fight infections.

Quit Smoking- Quitting is the best possible choice you can make to help your wound(s) heal faster,
safer, and with fewer problems. It is also the best way to start a healthy lifestyle. If you would like
more information on quitting please ask any member of your health care team.
