It contains almost 4000 different chemical substances. Potential Hazards of Smoking - Pneumonia Osteoporosis Osteoporosis • Osteoporosis is defined as a specific bone disorder that leads to the weakening and increased fragility of bones. Osteoporosis • With an increase in the number of cigarettes consumption, his risk of suffering from bone fractures in old age also increases. Osteoporosis • In addition, smokers are found to be less physically active and generally thinner. Smoking is considered as one of the risk factors of Osteoporosis. Heart Attack • Smoking, is one of the main risk factors for having a heart attack. • Smoking accelerates the process of atherosclerosis (narrowing of the arteries), which can lead to a heart attack. • Smoking can also increase the risk of blood clots, which can block arteries • Atherosclerosis is a condition where arteries become hardened and clogged • Clogged arteries can keep the heart from getting enough blood and oxygen and can cause chest pain. http://www.youtube.com/watch?v=qRK7DCDKEA • Cigarette smoking speeds up the process of atherosclerosis by damaging the cells lining the blood vessels and heart. •Cigarette smoking can increase your risk of dangerous blood clots, both because of the atherosclerosis and also because smoking causes blood platelets to clump together. • No matter how long you've been smoking, quitting will reduce your chances of having a heart attack. • Even among people with heart disease, the risk also drops sharply one year after quitting smoking, and it continues to decline over time, but the risk does not return to normal. Pneumonia What is pneumonia? ~A serious infection of the lung tissue by one of many different micro-organisms causing an inflammation in the lungs. - The infection causes the air sacs (alveoli) and smaller airways in your lungs to become inflamed and fill with fluid. - You can’t get enough oxygen from the air into your blood. Pneumonia can be caused by: - Bacteria - Viruses - Fungi -Chemical exposure - Parasites Pneumonia is defined by its location: Lobar pneumonia - inflammation affects a section, lobe part of a lung Bronchopneumonia - The term double pneumonia means both lungs are affected. - a patchy infection occurring throughout the lungs. How is smoking related to Pneumonia? Symptoms of pneumonia COUGH which is usually dry at first, later with phlegm. PHLEGM is often green-yellow in colour or rust-coloured. It is smelly. The cough worsens over time. Other than coughing…. ~ Fever ~ Pain in your chest ~ Night sweats ~ Confusion ~ Breathlessness or faster breathing ~Severe shaking and chills. ~Severe chest pain or tightness in the chest. ~Loss of appetite. ~Tiredness and fatigue ~General muscle aches. Cancers Smoking & Cancers • Tar causes lung cancer irritates the trachea, makes it narrower. • In the trachea and bronchi of a smoker, cilia are destroyed by the chemicals in cigarette smoke ==>mucus is not swept away from the lungs, but remains to clog the air passages. Lungs Cancer carbon monoxide (inside cigarette smoke) lowers the amount of oxygen in blood. Carbon dioxide combine with the hemoglobin the blood carries much less oxygen round the body Smoking & Cancers Smoking • affects the function of the immune system • increase the risk for respiratory, infections Smoking & Cancers • Cigarette smoking alone is directly responsible for approximately 30% of all cancer deaths annually in the United States. • Cigarette smoking also contributes to lung disease, heart disease, stroke, and the development of low birth weight babies. • Cigarette smoking, cigar smoking and passive smoking can all contribute to both non-small cell lung cancer and small cell lung cancer. Smoking is responsible for most cancers: • Larynx • Oral cavity • Lip • Tongue • Esophagus • Mouth • Bladder • Throat • Lung • Emphysema Highly associated with the development of and deaths from: • Liver cancer • kidney cancer • Stomach cancer • Cancer of the nasal cavities • Pancreatic cancer • Cervical cancer Staging Lung Cancer • Cancer spread to other parts of the body For Example: Lung Cancer • often spreads to the brain or bones Ways to Prevent Lung Cancer 1. Quit smoking NOW • Quitting smoking is the BEST defense against cancers. 2. Keep away from passive smoking • Reduce the chance of breathing in the smoke from cigarette smokers • Reduce the risk of getting lung cancer and heart disease 3. Eat more fruits and veggies • repair damaged cells The End
