You smoke? Well why don’t you just drink poison?
Let’s start with what smoking actually does to the body. Smoking harms nearly every organ of the body. Smoking causes many diseases and reduces the health of smokers in general. It primarily starts at the lungs. How? Well think of your lung tissue with openings all over which are air sacs called alveoli. This is an anatomical structure that has the form of a hollow cavity which does the exchange of oxygen and carbon dioxide in and out of our body, when we inhale and exhale. The thing to know about this tissue is that before you start smoking the alveoli are expandable (think of it like a rubber band) allowing the person to get a good exchange of oxygen getting in the body to go to all our tissues and carbon dioxide getting out of the body (O2=oxygen being the fuel to our tissues and without it causes cellular starvation, carbon dioxide=CO2 being an acid / toxin to the human body and exhaled by the lungs). After years of smoking the alveoli stretches out not allowing a good exchange of O2 and CO2. The sad thing for a smoker is the alveoli cannot REVERSE back after damage has already occurred unless you had a lung transplant with continuing to smoke, which no M.D. or health insurance would allow. More realistic would be QUIT the bad habit. The tissue doesn’t get completely better but it improves when you quit. So the pt with Emphysema has alveoli that can’t exchange oxygen and carbon dioxide from the blood like it use to at the bottom of the lungs, prior to even starting to smoke. Also, after smoking years and when diagnosed with COPD you have difficulty breathing (that is why smoking is a major cause of bronchitis or Emphysema=types of chronic obstructive pulmonary disease=COPD and it is not REVERSIBLE). Emphysema is the worst type of COPD you can get. COPD is the third leading cause of death in the U.S., and the economic burden of COPD in the U.S. in 2007 was $42.6 billion in health care costs and lost productivity. Isn’t this reason enough to stop smoking?
Emphysema is an enlargement of the air spaces distal to the terminal bronchioles, with destruction of their walls. People with emphysema have historically been known as “Pink Puffers”, due to their pink complexion.
Chronic bronchitis is defined in clinical terms as a cough with sputum production on most days for 3 months of a year, for 2 consecutive years. People with advanced COPD that have primarily chronic bronchitis were commonly referred to as “Blue Bloaters” because of the bluish color of the skin and lips (cyanosis) along with hypoxia and fluid retention.
Know when the lungs get effected in time the heart gets effected. One affects the other in time. The heart can’t live without the lungs and vice versa.
Now knowing just this you’ll understand why smoking alone can cause the following conditions, Through the Centers for Disease Control and Prevention. They state the following:
Smoking and Increased Health Risks
Compared with nonsmokers, smoking is estimated to increase the risk of—
- Coronary heart disease by 2 to 4 times, (causing atherosclerosis=thickening of the vessels or due to arteriosclerosis=hardening of the arteries and remember smoking causes vasoconstriction of the vessels = increase pressure in the vessels = high B/P.
- Stroke by 2 to 4 times (Due to causing the above problems listed under coronary heart disease.)
- Men developing lung cancer by 23 times,
- Women developing lung cancer by 13 times(cancers due to constant irritation of the tissues) , and
- Dying from chronic obstructive lung diseases (such as chronic bronchitis and emphysema) by 12 to 13 times. ( Explained at the top)
Smoking and Cardiovascular Disease
- Smoking causes coronary heart disease, the leading cause of death in the United States.
- Cigarette smoking causes reduced circulation by narrowing the blood vessels (arteries) and puts smokers at risk of developing peripheral vascular disease (i.e., obstruction of the large arteries in the arms and legs that can cause a range of problems from pain to tissue loss or gangrene) This pain to gangrene to amputation is due to lack of oxygenated blood getting to the tissue caused by the vasoconstriction the cigarette smoking caused.
- Smoking causes abdominal aortic aneurysm (i.e., a swelling or weakening of the main artery of the body—the aorta—where it runs through the abdomen). An aneurysm with constant vasoconstriction (increases pressure) puts the aneurysm at risk for rupture because the aneurysm area isn’t as strong as the other vessels=Rupture of the aortic aneurysm
Smoking and Respiratory Disease
- Smoking causes lung cancer.
- Smoking causes lung diseases (e.g., emphysema, bronchitis, chronic airway obstruction) by damaging the airways and alveoli (i.e., small air sacs) of the lungs.
Smoking and Cancer
Smoking causes the following cancers: (in alphabetical order)
- Acute myeloid leukemia
- Bladder cancer
- Cancer of the cervix
- Cancer of the esophagus
- Kidney cancer
- Cancer of the larynx (voice box)
- Lung cancer
- Cancer of the oral cavity (mouth)
- Pancreatic cancer
- Cancer of the pharynx (throat)
- Stomach cancer
Smoking and Other Health Effects
Smoking has many adverse reproductive and early childhood effects, including increased risk for—
- Preterm delivery
- Low birth weight
- Sudden infant death syndrome (SIDS).1,2,9Smoking is associated with the following adverse health effects:1
- Postmenopausal women who smoke have lower bone density than women who never smoked.Women who smoke have an increased risk for hip fracture than women who never smoked.
