Emphysema refers to the destruction of Caloric intake and satiety alveoli air sacs Sports performance enhancement the lungs.
Alveoli are essential for the exchange of oxygen Unsafe diet methods the blood: when they break smokign the lung loses its elasticity and there is Respiraotry surface area of the lung to absorb oxygen.
The onset of the disease is very gradual, and breathlessness only becomes troublesome when about half of the lung has been destroyed, which means that diagnosis is often late. Although COPD can be the result of exposure to occupational hazards and air pollution, it is predominantly caused by active or secondhand tobacco smoke exposure.
Subsequently, the inflammation causes the airways to thicken and narrow and larger amounts of mucus to be produced. Quitting smoking once COPD has developed cannot reverse the progress of disease but can help to decelerate its worsening.
The most effective way to quit smoking is by using a combination of behavioural therapy and pharmacotherapy. Pneumonia is a form of an acute respiratory infection that causes inflammation of the lung, making breathing painful and limiting oxygen intake.
It is more widespread in autumn and winter. Community acquired pneumonia CAP has been associated with excess mortality over subsequent years following survival. Studies have shown that the risk of CAP is reduced by half, 5 years after stopping smoking.
Tuberculosis TB is an infectious disease caused by the Mycobacterium tuberculosis bacteria. Symptoms include a persistent cough, chest pain, weakness and fatigue, weight loss and other flu-like symptoms. Asthma is a chronic inflammatory disease that affects the airways and is characterised by respiratory symptoms such as wheeze, shortness of breath, chest tightness and cough that varies over time and in intensity, together with variable expiratory airflow limitation.
Exposure to cigarette smoke directly or second-hand is known to trigger the development of asthma and exacerbate symptoms. Second-hand smoke is responsible for a significant proportion of deaths from asthma, lower respiratory infections, lung cancer and ischemic heart disease.
As ofcountries have now implemented smokefree laws banning smoking in enclosed public places. Indeed, parental smoking is one of the major predictors of second-hand smoke exposure, in addition to low socio-economic status, being less educated and attitudes towards second-hand smoking.
Children under 5 years of age living in social housing — where there is also a concentration of other indicators of disadvantage — are 4 times more likely to be exposed to tobacco smoke compared to children living in owner occupied homes.

Dangerous chemicals in tobacco smoke Effects of smoking tobacco on the body Effects of smoking on the sexual organs Effects of smoking on babies Diseases caused by long-term smoking Where to get help. Dangerous chemicals in tobacco smoke Highly damaging components of tobacco smoke include: tar — is the word for the solid particles suspended in tobacco smoke. The particles contain chemicals, including cancer-causing substances carcinogens. Tar is sticky and brown, and stains teeth, fingernails and lung tissue carbon monoxide — is a poisonous gas. It is odourless and colourless and, in large doses, quickly causes death because it takes the place of oxygen in the blood. In people who smoke, the carbon monoxide in their blood makes it harder for oxygen to get to their organs and muscles oxidizing chemicals — are highly reactive chemicals that can damage the heart muscles and blood vessels of people who smoke. They react with cholesterol, leading to the build-up of fatty material on artery walls. Their actions lead to heart disease, stroke and blood vessel disease metals — tobacco smoke contains several metals that cause cancer, including arsenic, beryllium, cadmium, chromium, cobalt, lead and nickel radioactive compounds — tobacco smoke contains radioactive compounds that are known to be carcinogenic. 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. Effects of smoking on the musculoskeletal system The effects of tobacco smoke on the musculoskeletal system include: tightening of certain muscles reduced bone density. Effects of smoking on the sexual organs The effects of tobacco smoke on the male body include an increased risk for: 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 increased risk of cancer of the cervix greatly increased risk of stroke and heart attack if the person who smokes is aged over 35 years and taking the oral contraceptive pill. Other effects of smoking on the body Other effects of tobacco smoke on the body include: 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. Effects of smoking on babies The effects of maternal smoking on an unborn baby include: increased risk of miscarriage, stillbirth and premature birth weaker lungs low birth weight, which may have a lasting effect of the growth and development of children. Low birth weight is associated with an increased risk of heart disease, high blood pressure, and diabetes in adulthood increased risk of cleft palate and cleft lip increased risk of attention deficit hyperactivity disorder ADHD. Diseases caused by long-term smoking A person who smokes throughout their life is at high risk of developing a range of potentially lethal diseases, including: cancer of the lung, mouth, nose, larynx, tongue, nasal sinus, oesophagus, throat, pancreas, bone marrow myeloid leukaemia , kidney, cervix, ovary, ureter, liver, bladder, bowel and stomach lung diseases such as chronic bronchitis and chronic obstructive pulmonary disease, which includes obstructive bronchiolitis and emphysema heart disease and stroke ulcers of the digestive system osteoporosis and hip fracture poor blood circulation in feet and hands, which can lead to pain and, in severe cases, gangrene and amputation type 2 diabetes rheumatoid arthritis.

| How Smoking Impacts Your Lung Health [Video] | Imagine doing those with a healthy nonsmoker's lung. Doing those same activities is much more strenuous and challenging with the smoker's lung. Another thing I would like to show you: in the smoker's lung there are these little porous holes. Those are where those air sacs we talked about earlier have now burst open. With each puff you take off of a cigarette, you pop those air sacs. And unfortunately, that's the only tobacco-related illness that's not reversible. It's called emphysema. Think about it: at eight to ten puffs per cigarette, you're popping up to air sacs in a day at one pack per day. The good news? Everything else is reversible once you quit. You can clean out the rest of that tar. What's important to know? It's never too late to quit. The American Lung Association firmly believes every tobacco user can quit. We know it's not easy, and that's why the Lung Association is here to provide you with the support and resources to obtain and maintain a tobacco-free lifestyle. The American Lung Association's Freedom From Smoking is a proven effective smoking cessation clinic program which has successfully helped smokers quit for more than 40 years. Freedom From Smoking is offered in a variety of different options, including in-person group cessation clinics, online, over the phone, and through a simple, step-by-step self-help guide.

The younger a person is when he or she starts smoking, the greater their risk of developing lung cancer. A US study found that smoking during the teenage years causes permanent genetic changes in the lungs and forever increases the risk of lung cancer, even if the smoker subsequently stops. Chronic obstructive pulmonary lung disease including chronic bronchitis and emphysema is a progressively disabling disease. It can cause prolonged suffering due to difficulty in breathing because of the obstruction or narrowing of the small airways in the lung and the destruction of the lung's air sacs due to smoking. The onset of the disease is very slow and breathlessness only becomes troublesome when about half of the lung has been destroyed. The disease is rarely reversible. Smoking is the main cause of chronic obstructive lung disease: it is very rare in non-smokers. According to the latest World Health Organization statistics, currently million people have COPD and it will become the third leading cause of death worldwide by Pneumonia is much more common for smokers. It was found that people who smoke more than 20 cigarettes per day were almost three times more likely to acquire pneumonia than people who never smoked. Cigarette smoke has been found to cause asthma both in adult smokers and in children around smokers. Quitting smoking reduces the risk of cancer and respiratory problems. However, regardless of age, people who quit smoking are less likely than those who keep smoking to die from a smoking-related illness. Retrieved November 2, et al.

People with chronic bronchitis have more frequent respiratory infections. Chronic bronchitis often co-occurs with COPD, but it does not influence airflow limitation unless the inflammation extends into the small airways.
However, since then research has shown that airflow limitation can develop without symptoms of chronic bronchitis. Smoking is a long-recognised cause of chronic bronchitis. Asthma is a common chronic respiratory disease affecting approximated one in nine people in Australia. Severe asthma can be life-threatening, causing deaths in Australia in Asthma usually starts in childhood and often becomes less frequent over time.
However, it may continue for some people, reoccur, or begin later in life. These time periods can mean that it is difficult to be certain if exposure to tobacco smoke has preceded the disease onset, complicating studies of causality.
Many of these studies showed an increased risk of asthma among adolescent smokers, but there were a limited number of high-quality studies. The report concluded that the available evidence suggested but is insufficient to conclude that active smoking is a cause of asthma in adolescents.
Similarly, this report also concluded that the evidence suggested, but was insufficient to conclude that smoking increases the incidence of asthma in adults. Smoking exacerbates asthma in adults and leads to poor asthma control.
Smoking cessation may improve asthma control. See Section 3. Interstitial lung diseases are a group of disorders that are mostly characterised by progressive scarring of interstitial alveolar tissue.
The pathophysiology is often fibrosis scar tissue formation and inflammation. Some of these disorders are caused or triggered by exposure to toxic materials, or associated with auto-immune diseases, connective tissue diseases or the use of certain drugs.
Idiopathic pulmonary fibrosis is a progressive, fatal fibrotic interstitial lung disease. It is one of the most common and most severe interstitial lung diseases. It has the worst prognosis of all idiopathic interstitial diseases of the lung, with a median survival time of three to four years.
The report of the US Surgeon General reviewed 12 studies on the risk of idiopathic pulmonary fibrosis in smokers. The two largest studies reported odds ratios of 1. However, there are some problems with the quality of the epidemiological studies, such as inconsistent adjustment for potential confounders.
The report concluded that the evidence suggested but was insufficient to conclude that smoking is a cause of idiopathic pulmonary fibrosis. Respiratory bronchiolitis-interstitial lung disease RB-ILD is seen in very heavy smokers, typically those smoking more than 30 cigarettes per day.
Unlike typical COPD, it can be seen in young smokers. RB-ILD impairs lung function and has an abnormal appearance on chest X-rays. Smoking cessation is recommended. Histiocytosis X is a rare cancer that causes damage to variable regions of the body. Pulmonary histiocytosis X involves the development of inflammatory nodules in the lung along with cystic degeneration of the lungs themselves.
It has a distinct appearance on X-rays. Patients are commonly young adults and the vast majority have a history of smoking. For recent news items and research on this topic, click here. Last updated November US Department of Health and Human Services.

COVID is a respiratory viral infection that affects the lungs and airways, and can cause life threatening systemic inflammation and pulmonary and cardiovascular complications.
The Zoe symptom study of 2. Lung cancer is one of the most common and severe types of cancer and it remains the leading cause of cancer death worldwide. A major study in the UK found that people who smoked around 20 cigarettes a day had 26 times the lung cancer risk of non-smokers, and those who smoked three cigarettes a day had 6 times greater risk.
A year longitudinal study of smoking among British doctors found substantial long-term health risks associated with smoking, including increased rates of lung cancer and COPD.
Another study which modelled absolute risk of lung cancer mortality following smoking cessation at different ages, found that the risk of lung cancer mortality remains elevated after quitting, relative to non-smokers, but that those who quit at younger ages had a lower risk than those who quit later in life.
Although minor benefits may also be obtained through attempts to reduce cigarette intake, these are likely to only emerge if smokers reduce their cigarette consumption by a significant amount i. Quitting smoking is also the most effective way for smokers who have been diagnosed with early stage lung cancer to improve their outcomes.
The Global Initiative for Chronic Obstructive Lung Disease GOLD defines COPD as a progressively disabling disease characterised by airflow obstruction that interferes with normal breathing. Individuals of low socioeconomic status are more likely to be diagnosed and to die from COPD than those of higher socioeconomic status.
The UK has the 12th highest number of recorded deaths from COPD in the world, with around 1. Making a diagnosis relies on clinical judgement based on a combination of history, physical examination and confirmation of the presence of airflow obstruction using spirometry — a breath test measuring pulmonary function.
COPD is an umbrella term which includes two main pathological processes - chronic bronchitis which affects the airways and emphysema where the lung tissue is damaged. People with chronic bronchitis have intermittent attacks of obstructed breathing during which their airways become inflamed, narrowed and clogged with mucus.
Emphysema refers to the destruction of the alveoli air sacs in the lungs. Alveoli are essential for the exchange of oxygen in the blood: when they break down the lung loses its elasticity and there is less surface area of the lung to absorb oxygen.
