The symptoms can get better at times, but the cough keeps coming back.
Over time, the airways get blocked by scar tissue and mucus, which can lead to bad lung infections (pneumonia).
Smoking increases risk of macular degeneration(AMD, this is painless eye condition), cataracts(eye condition), and poor eyesight.
It can also weaken your sense of taste and sense of smell, so food may become less enjoyable.
The late stage is one of the most miserable of all illnesses.
It makes people gasp for breath and feel as if they are drowning. It’s a disease where the airways make too much mucus, forcing the person to cough it out. The airways become inflamed (swollen) and the cough becomes chronic (long-lasting).In a condition called emphysema, the air sacs in your lungs are destroyed.In chronic bronchitis, the lining of the tubes of the lungs becomes inflamed.People with emphysema are at risk for many other problems linked to weak lung function, including pneumonia.In later stages of the disease, patients can only breathe comfortably with oxygen.Looking at the respiratory system, When you inhale smoke, you’re taking in substances that can damage your lungs.here are some of them ; Tar - a mixture of dangerous chemicals Arsenic - used in wood preservatives Benzene - an industrial solvent, refined from crude oil Cadmium - used in batteries Formaldehyde - used in mortuaries and paint manufacturing Polonium-210 - a highly radioactive element Chromium - used to manufacture dye, paints and alloys 1,3-Butadiene - used in rubber manufacturing Polycyclic aromatic hydrocarbons - a group of dangerous DNA-damaging chemicals Tobacco-specific nitrosamines - a group of carcinogens only found in tobacco Acrolein - used as a chemical weapon in World War 1 - and acetaldehyde - used in the industrial production of acid Over time, your lungs lose their ability to filter harmful chemicals.Not only does smoking increase the risk for lung cancer, it’s also a risk factor for cancers of the: Cigarettes, cigars, pipes, and spit and other types of smokeless tobacco all cause cancer. Smoking damages the airways and small air sacs in your lungs.This damage starts early in smokers, and lung function continues to worsen as long as the person smokes.Coughing can’t clear out the toxins sufficiently, so these toxins get trapped in the lungs.Smokers have a higher risk of respiratory infections, colds, and flu.
