Health hazards associated with smoking.
Smoking is one of the major of death and illness in the UK. Yearly about
100,000 people die from smoking, with many more deaths caused
by smoking-related illnesses. Smoking increases your risk of developing more
than 50 serious health conditions. Some may be fatal and others can cause
irreversible long-term damage to your health.
The sad thing about it is that the health of people around the smoker is
also at risk (passive smoking, or secondhand smoke). We hope this series of
articles on smoking would make readers with the habit think twice before
pulling out another stick. It would also educate/ remind non-smokers of the
health implications of second hand smoking. first let us look at the risks
associated with smoking.
Health risks
- Smoking causes about 90% of lung cancers:
It also causes cancer in many other
parts of the body, including the mouth lips, throat, voice box
(larynx), oesophagus (the tube between your mouth and stomach), bladder,
kidney, liver, stomach and pancreas.
- Smoking damages your heart and your
blood circulation, increasing your risk of developing conditions
such as:
·
stroke
·
peripheral vascular disease (damaged blood
vessels)
·
cerebrovascular disease (damaged arteries
that supply blood to your brain)
·
Raised blood pressure and heart rate
·
Constriction (tightening) of blood vessels in
the skin, resulting in a drop in skin temperature
·
Less oxygen carried by the blood
·
‘Stickier’ blood, which is more prone to
clotting
·
Damage to the lining of the arteries, which is
thought to be a contributing factor to atherosclerosis (the build-up of fatty
deposits on the artery walls)
·
Reduced blood flow to extremities (fingers and
toes)
·
Increased risk of stroke and heart attack due to
blockages of the blood supply.
3. Smoking damages your lungs: smokers are at high risk of suffering
from the following lungs conditions
·
chronic bronchitis (infection of the main
airways in the lungs)
·
emphysema (damage to the small airways in
the lungs)
·
pneumonia (inflammation in the lungs)
4. Prolongs
or worsens symptoms of respiratory conditions: Smoking can worsen or
prolong the symptoms of respiratory conditions such as asthma, or respiratory
tract infections such as the common cold.
5. Effect
on fertility: The effects of tobacco smoke on the male body include:
·Lower
sperm count
·Higher
percentage of deformed sperm
·Genetic
damage to sperm
·Impotence,
which may be due to the effects of smoking on blood flow and damage to the blood vessels of the penis.
The effects of
tobacco smoke on the female body include:
·Reduced
fertility
·Menstrual
cycle irregularities or absence of menstruation
·Menopause
reached one or two years earlier
·Increase
risk of cervical cancer
6. Effects of
smoking on the immune system: The effects of tobacco smoke on the immune
system include:
- Greater
susceptibility to infections such as pneumonia and influenza
- More
severe and longer-lasting illnesses
- Lower
levels of protective antioxidants (such as vitamin C), in the blood.
7. Other effects:
- Irritation
and inflammation of the stomach and intestines
- Increased
risk of painful ulcers along the digestive tract
- Reduced
ability to smell and taste
- Premature
wrinkling of the skin
- Higher
risk of blindness
- Gum
disease (periodontitis).
- Tightening
of certain muscles
- Reduced
bone density.
Secondhand smoke
Secondhand smoke comes from the tip of a lit cigarette and the smoke that
the smoker breathes out.
People who breathe in secondhand
smoke are at risk of getting the same health conditions as smokers,
particularly lung cancer and heart disease. For example, breathing in
secondhand smoke increases a non-smoker's risk of developing lung cancer or
heart disease by about 25%.
A child who is exposed to smoke (secondhand smoking) is at increased risk of
developing respiratory infections, a chronic cough and, if they have
asthma
,
their symptoms will get worse. They're also at increased risk of sudden
infant death syndrome (SIDS) and glue ear.
Smoking during pregnancy
If you smoke when you're pregnant, you put your unborn baby's health at
risk, as well as your own. Smoking during pregnancy increases the risk of
complications such as:
- miscarriage
- premature
(early) birth
- a low
birth weight baby
- stillbirth
- Increased
risk of cleft palate and cleft lip
- Paternal
smoking can also harm the fetus if the non-smoking mother is exposed to
second-hand smoke.
If a parent continues to smoke during their baby’s first year of life, the
child has an increased risk of ear infections, respiratory illnesses such as
pneumonia and bronchitis, sudden infant death syndrome (SIDS) and meningococcal
disease.
What about smokeless tobacco:
Smokeless tobacco is tobacco that is not burned. It includes chewing
tobacco, dip, snuff, and betel quid. At least 28 chemicals in these products
have been found to cause cancer, including:
- Esophageal
cancer
- Mouth
cancer
- Pancreatic
cancer
Betel quid is a combination of
betel leaf,
areca nut, and
slaked
lime. Like other smokeless tobacco products, betel quid and gutka are known
to cause:
- Esophageal
cancer
- Lip
cancer
- Mouth
cancer
- Pharynx
cancer
- Tongue
cancer
Smokeless tobacco also causes
·
gums to pull away from your teeth(
If this happens, the gums will not grow back)
·
leathery white patches and red sores
(Those patches and sores can turn into cancer).
