You’ve probably heard of this disclaimer on multiple occasions – ‘smoking is injurious to health’. What you may not immediately realise is the extent of the damage smoking can cause to your health and, most directly, your lungs.
Smoking is known to be the leading cause of preventable diseases and deaths globally. Nearly all forms of lung cancer—the top cause of cancer death in both men and women can be attributed to smoking. Tobacco and tobacco-related products can damage the lungs’ ability to supply oxygen to the body. Other substances commonly found in cigarette smoke can cause permanent lung damage, even in small amounts.
A single puff of cigarette smoke contains upwards of 7,000 chemicals. Tobacco smoke contains over 70 known cancer-causing chemicals. When you breathe these in, these toxins go deep into your lungs and can cause swelling, resulting in a host of other respiratory diseases.
Both tobacco and chemical substances found in cigarettes can change the cellular structure of the lungs. They can cause the elastic walls within the airways to break down – resulting in less functioning surface area in the lungs. Cigarettes can damage lung tissue, preventing them from functioning correctly. This can increase the risk of diseases caused by smoking, such as chronic bronchitis, emphysema, respiratory diseases, asthma and COPD (Chronic Obstructive Pulmonary Disease).
Nicotine in tobacco can also damage the ability of the respiratory system to filter out dust and dirt. This can lead to toxic substances passing through, resulting in lung congestion and the ‘smoker’s cough’.

A person who smokes throughout life is at high risk of developing a range of potentially fatal diseases owing to impaired lung function and breathlessness due to swelling and narrowing of the lung airways and excess mucus build-up. They are also prone to weakening the lungs’ clearance system, leading to the accumulation of toxic substances and causing lung irritation and damage. Further, they are also at an increased risk of lung infection, chronic bronchitis and heightened risk of asthma, along with permanent damage to air sacs.
In the longer term, smoking is known to induce heart disease and stroke, in certain cases, it can cause ulcers of the digestive system and put smokers at increased risk of type 2 diabetes.
Most smokers are also likely to develop emphysema. The number of cigarettes you smoke and other lifestyle factors may impact the extent of the damage. If you’re diagnosed with either of these respiratory diseases – emphysema or chronic bronchitis, you run the risk of being diagnosed with chronic obstructive pulmonary disease (COPD).

Smoking can affect a person’s health in other ways, too, harming almost every organ in the body. In most cases, it can result in a compromised immune system function, making you susceptible to many other illnesses. It can also lead to lower bone density (brittle bones), which increases the risk of broken bones and fractures. Smoking also leaves you at a higher risk of rheumatoid arthritis, heart disease and stroke, along with an increased risk for cataracts (clouding of the eye lenses).
Apart from respiratory diseases, other visible disorders include an increased risk of oral cancers, gum disease and tooth loss, premature ageing of the skin, bad breath and stained teeth and an increased risk for age-related macular degeneration, which can lead to blindness. Moreover, even your wounds may take longer to heal!

It’s never too late to quit smoking. Within days of quitting smoking, lungs begin to repair themselves. In fact, just 12 hours after you quit, the amount of carbon monoxide in your blood drops to a much healthier level. More oxygen flows to your vital organs and you will be able to breathe better. In about 10 to 15 years, your risk of developing lung cancer reduces and may even become the same as a non-smoker.

Lungs are one of the most affected organs with the changing temperatures and climate. Respiratory disorders stem from a lot of causes- the primary being a genetic predisposition and environmental factors. Exposure to agents that are harmful can also cause severe lung problems. Let us take a look at the most common ones and what you should know about them.
Cold is one of the most common lung infections. It spreads from someone’s coughs and sneezes who are already sick with a cold. It is a viral infection and can trigger bouts of asthma and even pneumonia. The cold has no cure.
When the bronchioles in the lungs get inflamed, it can trigger an asthma attack which causes swelling up of the airways and leads to breathing difficulties. A dry cough, wheezing and shortness of breath are common symptoms. Allergens, pollution and other infections can trigger asthma.
Asthma is a common chronic illness of the lungs and the airways in children, with symptoms such as cough, wheezing, shortness of breath, and more, early diagnosis is often helpful.

Chronic Obstructive Pulmonary Disease or COPD is the common term for many respiratory issues that is symptomized by breathlessness, problems in exhalation, mucus in the lungs, and shortness of breath. It takes time to identify COPD as it takes a long while to develop and the symptoms are usually thought of as an aging process. It is related to smoking.
When the bronchioles, the tubes that carry the air to and fro from the lungs get inflamed, it is known as bronchitis. Allergens, cold, flu, and pollution can cause bronchitis. Colored mucus, sometimes it even has blood, a fever and the infection that lasts for more than three weeks usually are symptoms of bronchitis. It is treated with antibiotics.
When the air sacs in the lung get filled with fluid due to a viral or a bacterial infection, it is known as pneumonia. Fever, breathlessness, cough with thick mucus are some of the symptoms. For pneumonia caused by bacteria, antibiotics help. Drinking lot of fluids is also beneficial.
Rapid breathing, difficulty breathing, or shortness of breath, using rib or neck muscles to help breathe are common signs that one should be vigilant about to diagnose lung disease at an early stage.
Dr. Ashish Bajaj – M.B.B.S, M.D.
When the space between the lungs and the chest wall fills up with fluid, it is known as pleurisy or pleural effusion. This could happen because of pneumonia, congestive heart failure or even cancer. Discomfort in the chest and breathlessness are common symptoms.
Apart from the ones in the blog public should be made aware of Tuberculosis which is a major public health problem and is completely curable. If anyone has cough for more than 2 weeks please get yourself tested for Tuberculosis.
Dr. M.G. Kartheeka, MBBS, MD
It is a genetic disease that causes lung airways to clog up with thick, sticky mucus. The patient falls prey to lung infections repeatedly. Frequent lung infections, repeated coughing and poor growth rate with a salty taste on the skin are common symptoms.
This is one of the hardest cancers to detect. It can develop anywhere in the lungs. The tumors pop up near the air sacs. Chronic coughing, voice changes, blood in cough and harsh breathing sounds are common symptoms.
Smoking causes most lung infections. Avoid people sick with lung infections and places that are dusty and are exposed to harsh chemicals. Quit smoking to stay lung happy.
