How does smoking affect my
bones?
Recent studies show a direct relationship between
tobacco use and decreased bone density. Smoking is one of many
factors—including weight, alcohol consumption, and activity level—that increase
your risk for osteoporosis, a condition in which bones weaken and become more
likely to fracture.
Significant bone loss has been found in older women
and men who smoke. Quitting smoking appears to reduce the risk for low bone
mass and fractures. However, it may take several years to lower a former
smoker’s risk.
In addition,
smoking from an early age puts women at even higher risk for osteoporosis.
Smoking lowers the level of the hormone estrogen in your body,
which can cause you to go through menopause earlier, boosting your risk for
osteoporosis.
How does smoking affect my heart
and blood vessels?
The chemicals in tobacco smoke harm your blood
cells and damage the function of your heart. This damage increases your risk
for:
·
Atherosclerosis,
a disease in which a waxy substance called plaque builds up in your arteries
·
Aneurysms,
which are bulging blood vessels that can burst and cause death
·
Cardiovascular
disease (CVD), which includes:
- Coronary
heart disease (CHD), narrow or blocked arteries around the heart
- Heart
attack and damage to your arteries
- Heart-related
chest pain
- High
blood pressure
·
Coronary Heart
disease, where platelets—components in the blood—stick together along with
proteins for form clots which can then get stuck in the plaque in the walls of
arteries and cause heart attacks
·
Peripheral
arterial disease (PAD), a condition in which plaque builds up in the arteries
that carry blood to the head, organs, and limbs
·
Stroke,
which is sudden death of brain cells caused by blood clots or bleeding
Breathing tobacco smoke can even change your blood
chemistry and damage your blood vessels. As you inhale smoke, cells that line
your body’s blood vessels react to its chemicals. Your heart rate and blood
pressure go up and your blood vessels thicken and narrow.
How does smoking affect my lungs
and breathing?
Every cigarette you smoke damages your breathing
and scars your lungs. Smoking causes:
·
Chronic
obstructive pulmonary disease (COPD), a disease that gets worse over time and
causes wheezing, shortness of breath, chest tightness, and other symptoms
·
Emphysema,
a condition in which the walls between the air sacs in your lungs lose their
ability to stretch and shrink back. Your lung tissue is destroyed, making it
difficult or impossible to breathe.
·
Chronic
bronchitis, which causes swelling of the lining of your bronchial tubes. When
this happens, less air flows to and from your lungs.
- · Pneumonia
- · Asthma
- · Tuberculosis
People with asthma can suffer severe attacks when
around cigarette smoke.
Can smoking affect my
vision?
Smoking is as bad for your eyes as it is for the rest
of your body. Research has linked smoking to an increased risk of developing
age-related macular degeneration, cataract, and optic nerve damage, all of
which can lead to blindness.
Do cigarettes cause cancer?
Tobacco
smoke contains more than 7,000 chemicals. About 70 of them are known to
cause cancer. Smoking cigarettes is the number-one risk
factor for lung cancer. But, smoking can affect your entire body, and is known
to cause cancer in the:
- · Lungs
- · Trachea
- · Bronchus
- · Esophagus
- · Oral Cavity
- · Lip
- · Nasopharynx
- · Nasal Cavity
- · Larynx
- · Stomach
- · Bladder
- · Pancreas
- · Kidney
- · Liver
- · Uterine Cervix
- · Colon
- · Rectum
In addition, smoking is known to cause
leukemia.
Do light cigarettes cause cancer?
There is
no such thing as a safe cigarette. People who smoke any kind of cigarette are
at an increased risk for smoking-related diseases. Although it is no longer
legal to sell light cigarettes, people who smoked light cigarettes in the past
are likely to have inhaled the same amount of toxic chemicals as those who
smoked regular cigarettes. They remain at high risk of developing
smoking-related cancers and other diseases.
Do menthol cigarettes cause
cancer?
All cigarettes are harmful, including menthol
cigarettes. Many smokers think menthol cigarettes are less harmful, but there
is no evidence that menthol cigarettes are safer than other cigarettes. Like
other cigarettes, menthol cigarettes harm nearly every organ in the body and
cause many diseases, including cancer, cardiovascular diseases, and respiratory
diseases. Menthol cigarettes, like other cigarettes, also negatively impact
male and female fertility and are harmful to pregnant women and their unborn
babies.
Some
research shows that menthol cigarettes may be more addictive than non-menthol
cigarettes. More research is needed to understand how addiction differs between
menthol and non-menthol cigarette use.
Can smoking cigars and pipes
cause cancer?
Cigar and pipe smoke, like cigarette smoke,
contains toxic and cancer-causing chemicals that are harmful to both smokers
and non-smokers. Cigar and pipe smoking causes:
- · Bladder cancer
- · Esophageal cancer
- · Laryngeal (voice box) cancer
- · Lip cancer
- · Lung cancer
- · Mouth cancer
- · Throat cancer
- · Tongue cancer
If you
smoke cigars daily, you are at increased risk for developing heart disease and
lung diseases such as emphysema.
