Our estimates indicate that, after 25 years of smoking, at least 25% of smokers without initial disease will have clinically significant COPD and 30–40% will have any COPD.
Conclusion: The authors conclude that in a primary care practice, about 8 percent of middle-age male smokers progress to moderate COPD over five years. Those most at risk are older, began smoking at an early age, and have contacts with their physician because of cough and other respiratory problems.
So if you smoked, you know, one cigarette a day for maybe a year, probably your risk is very little. But if you smoked a pack a day for 20 years, then 20 to 30 years later you are still at risk.
People who quit smoking decades ago are still at risk for lung diseases like chronic obstructive pulmonary disease (COPD), according to a study published online Oct.
People with larger airways relative to lung size may be able to withstand lung damage from smoking and still have enough breathing reserve to prevent them from developing COPD.
While lung tissue cells do regenerate, there's no way a smoker can return to having the lungs of a non-smoker. At best, they will carry a few scars from their time smoking, and at worst, they're stuck with certain breathing difficulties for the rest of their lives.
COPD does not usually become noticeable until after the age of 35 and most people diagnosed with the condition are over 50 years old. See your GP if you have the following symptoms: increasing breathlessness when exercising or moving around. a persistent cough with phlegm that never seems to go away.
Stage 1 Symptoms are mild and often unnoticed, except during times of exertion. These include mild shortness of breath and a nagging dry cough. Stage 2 Shortness of breath worsens, accompanied by a persistent cough and phlegm production. Flare-ups can cause changes in phlegm color.
The exact length of time you can live with COPD depends on your age, health, and symptoms. Especially if your COPD is diagnosed early, if you have mild stage COPD, and your disease is well managed and controlled, you may be able to live for 10 or even 20 years after diagnosis.
"COPD is a disease with a lot of moving parts," says Albert A. Rizzo, MD, chief medical officer for the American Lung Association. "It's not a death sentence by any means. Many people will live into their 70s, 80s, or 90s with COPD.”
Your lung function can improve by up-to 30%. You might notice the impact of this in a reduction in shortness of breath when exercising. The fibres in your lungs that help to reduce mucus build-up and protect against bacterial infection might start to grow back.
Smoking is the best-known risk factor for chronic obstructive pulmonary disease (COPD), a debilitating lung condition that can severely limit a person's day-to-day activities. But curiously, only a minority of lifelong smokers develops the disease, while non-smokers represent more than 25% of all COPD cases.
While tobacco smoking is a major risk factor for COPD, only approximately 20 % of smokers develop the disease.
Quitting smoking cannot completely reverse COPD, but it can help slow the progression of the disease and may improve the body's response to treatment. As well as preventing any further damage to the lungs, quitting smoking can improve the immune system.
There's currently no cure for chronic obstructive pulmonary disease (COPD), but treatment can help slow the progression of the condition and control the symptoms. Treatments include: stopping smoking – if you have COPD and you smoke, this is the most important thing you can do.
The main symptoms of COPD are breathlessness, chronic cough and sputum (mucus or phlegm) production. Cigarette smokers and ex-smokers are most at risk of COPD. There is no cure for COPD, and the damaged airways don't regenerate.
Although COPD is terminal, people may not always die of the condition directly, or of oxygen deprivation. Some people with COPD have other medical conditions, particularly cardiovascular disease. In fact, within 5 years of diagnosis, COPD is also an independent risk factor for sudden cardiac death.
Definition of mild COPD
The most common presenting symptom is dyspnea with exertion or chronic cough with or without sputum production. Other (but more infrequent) symptoms include chest pain, orthopnea and wheezing. However, there is also a group of patients with abnormal spirometry but are otherwise asymptomatic.
You can do a little checking yourself with a stopwatch. Take a full breath; hold if for one second. Then, with your mouth open, blow out as hard and fast as you can. Your lungs should be completely emptied – meaning that you can blow no more air out even though you try– in no more than 4 to 6 seconds.
Background: Heavy smokers (those who smoke greater than or equal to 25 or more cigarettes a day) are a subgroup who place themselves and others at risk for harmful health consequences and also are those least likely to achieve cessation.
The genetic sequences identified in healthy older smokers may have a protective effect, which is why they have survived despite the significant ill effects of their habit.
