Did you know that according to the World Health Organization (WHO), Tobacco is a leading preventable cause of death across the globe? Research shows that tobacco not only harms the lungs but also has the potential to damage nearly every single organ in the body. Its effects go much beyond what our eyes can see, and that is exactly what we’re about to find out in the blog below. Let’s get to know more about tobacco’s hidden harm and understand how its dangers extend far beyond what most people realise.

How Does Tobacco Damage Your Body?

Tobacco is known to have over 7,000 chemicals, of which at least 250 are listed as harmful to the body. Some of the commonly known chemicals include:

• Nicotine: It is a harmful substance present in tobacco that alters brain chemistry, narrows veins, and is also known to cause immense damage to the heart.
• Tar: It contains large amounts of cancer-causing chemicals that stick to your lungs, making it difficult to breathe.
• Carbon monoxide: It affects the body’s oxygen supply and makes it difficult for the heart to pump blood effectively. Over time, it can also cause your airways to swell up, allowing less air into the lungs.
• Formaldehyde: It is known to cause cancer and respiratory problems.
• Arsenic: It can cause various cancers, including skin, bladder, and lung cancer. It also causes immense damage to the body’s blood vessels and the heart.
• Tiny particles: Minute particles present in the tobacco smoke irritate the throat, causing smoker’s cough, which in turn leads to the production of excess mucus that damages the lungs.

Effects of Tobacco on Health

Tobacco not only harms the quality of life but also reduces life expectancy in the long run. It increases the risk of contracting several diseases as well as experiencing premature death. As it takes time for smoking-related issues to show up, people often assume they aren’t at risk and continue the ill habit for long periods. What most fail to realize is that the damage begins quietly, long before it starts to show any visible signs.

Diseases and Conditions Caused By Tobacco

Tobacco usage has been linked to a wide range of life-threatening conditions. While most people associate it with lung cancer or lung damage, its effects go much beyond our respiratory system. Listed below are some of the common tobacco-related illnesses and the damage they cause to the human body.

Lung Diseases

Lung Cancer 

Studies have shown that tobacco is the primary cause of most lung cancers. Furthermore, it also has the potential to cause cancers anywhere in the body, including the mouth, throat, liver, stomach, kidney, blood cells, and so on. Smoking can also cause severe lung damage and lead to conditions like tuberculosis, chronic cough, or even loss of permanent lung tissue.

Chronic Obstructive Pulmonary Disease (COPD)

Smoking is said to be one of the major contributors to the development of Chronic Obstructive Pulmonary Disease (COPD). In COPD, the airways present in the lungs are severely damaged, making it difficult for them to transport oxygen to the rest of the body. Over time, the condition can worsen, making breathing difficult even when you’re at rest. While there isn’t any cure for it, certain medications help reduce the symptoms and manage the condition. However, active smoking can worsen the condition and even lead to death.

Asthma

One of the many effects of tobacco on health includes its role in worsening or triggering the onset of asthma in adults as well as children. It leads to swelling and irritation in the lungs, two of the primary features of asthma. The damage caused to the lungs makes them more prone to asthma attacks, worsening the condition and impacting overall health in the long run.

Heart Disease

As dangerous as it sounds, smoking tobacco narrows down blood vessels, making it harder for the heart to pump blood effectively, causing Coronary Heart Disease (CHD). Common symptoms of CHD include shortness of breath, nausea, discomfort, pain in the chest, and fatigue. Furthermore, continuous smoking leads to atherosclerosis, a condition in which there is an immense plaque buildup on the artery walls. This condition is considered to be a contributing factor to Coronary Heart Disease.

Stroke

Heart attacks and strokes are very common among smokers. The nicotine present in tobacco raises the heart rate, causing extra stress to the cardiovascular system. It also causes high blood pressure and lowers your ability to perform any physical exercises, which in turn leads to blood clots that can potentially trigger heart attacks or strokes.

Diabetes

Studies show that people who smoke are more likely to develop type 2 diabetes. Smoking impacts the body’s ability to effectively regulate blood sugar levels, which increases insulin resistance, making blood sugar control more difficult.

Oral Disease

Smoking harms your oral health in more than just one way. From having stained teeth and bad breath to damaged gums and developing oral cancer, tobacco does more harm than you might be aware of. Smoking also affects the blood flow that reaches your mouth, making you more susceptible to gum disease and infection.

Bones

Due to a lack of oxygen flow, the body’s muscles tend to become weak, resulting in lowered performance and an increase in recovery time. It also impacts the ability of bones to absorb calcium, which in turn makes them more susceptible to fractures and other bone-related injuries.

Conclusion

Smoking has been prevalent in society for centuries, but that does not lessen its harmful impact on health. From the lungs to the heart, smoking tobacco poses a severe threat to almost every single organ of the human body. Understanding its ill effects and the damage that can occur from the varied range of tobacco-related illnesses is a crucial step towards quitting tobacco. Your health is in your hands; quit smoking, and give your body the love and care it deserves. Say bye to tobacco and all the harmful effects it brings with it today!
