Small Habits, Big Impact: The Health Risks of Tobacco Explained

Consumption of tobacco in any form is one of the most dangerous habits affecting people of all ages, contributing to serious health issues by weakening the immune system, causing inflammation, damaging DNA, and increasing the risk of blood clots. Many of these life-threatening conditions, however, are preventable.

Observed every year on 31st May, World No Tobacco Day raises awareness about these risks and encourages individuals to quit this silent killer for good. Along with prioritizing a tobacco-free lifestyle, it is also wise to safeguard your health with adequate insurance, ensuring access to quality treatment without financial stress. Read on to explore some lesser-known health conditions caused by tobacco.

Health risks of using tobacco

1. Cancer:

Tobacco use damages multiple organs and is linked to over 15 types of cancer, including those of the lungs, liver, throat, stomach, pancreas, kidney, bladder, cervix, ovary, and bowel. It weakens the immune system and causes DNA damage over time, significantly increasing cancer risk.

Cancer is a life-threatening condition that may require long-term and expensive treatment. If there is a family history of cancer or if you are at risk of suffering from the condition due to your job or lifestyle habits, it is wise to keep critical illness insurance handy. In case you get diagnosed with this life-threatening condition, your insurer will give you a lump sum that you can use for your treatment.

2. Type 2 diabetes:

Tobacco and cigarette smoke contain harmful chemicals that affect how your body functions. These chemicals can cause ongoing stress and irritation in the body, which makes it harder to control blood sugar levels. Over time, this can increase the risk of developing Type 2 diabetes. This shows that tobacco use not only harms your lungs but can also lead to serious long-term health problems.

3. Breathing problems:

Smoking can lead to COPD or Chronic Obstructive Pulmonary Disease and restrict airflow in the lungs. Therefore, smoking can be life-threatening for people with respiratory conditions. Regular smoking can worsen existing asthma and also increase the risk of asthma in healthy individuals.

4. Heart conditions:

Smokers often suffer from life-threatening cardiovascular conditions, such as heart disease and stroke. Tobacco smoke damages the lining of the blood vessels and increases the risk of blood clots and inflammation. These issues restrict blood flow to different body parts and organs, leading to heart diseases.

5. Hip fractures:

Tobacco can also have a negative impact on your bone density. Smokers lose bone density at a faster rate, and this increases the risk of different types of fractures, particularly hip fractures. Smoking increases free radicals in the body, thereby causing bone resorption or shrinkage of bones.

6. Rheumatoid arthritis:

Rheumatoid arthritis is a chronic inflammatory disease that affects multiple joints in the body. The condition causes pain, stiffness and swelling and limits mobility. Smoking tobacco activates endogenous sources of free radicals, and these increase oxidative stress and inflammation of the joints or rheumatoid arthritis.

7. Ectopic pregnancy:

Ectopic pregnancy is a serious and potentially life-threatening condition in which a fertilized egg develops outside the uterus, most often in a fallopian tube. The pregnancy cannot sustain and can pose significant risks to the mother, if not treated promptly. Chemicals from cigarette smoke enter the bloodstream and can affect the reproductive system, increasing the risk of ectopic pregnancy and related complications.

8. Vision problems:

Smoking increases the risk of several eye conditions, including cataracts, age-related macular degeneration, dry eye syndrome, diabetic retinopathy, and glaucoma. Although these can also affect non-smokers, the risk is significantly higher in those who smoke. Tobacco use can damage the uvea, the middle layer of the eye, leading to symptoms such as pain, redness, blurred or distorted vision, and even vision loss.

9. Dental problems:

Smoking can lead to a serious gum disease called periodontitis, which damages the bones supporting the teeth. This can result in tooth sensitivity and even tooth loss. Additionally, if gum disease develops, continuing to smoke can slow down the healing process, making it harder to recover.

10. Hearing loss:

Smoking restricts blood flow to the inner ear and can irritate and inflame the eustachian tubes, which help drain fluid and maintain air pressure balance. When these functions are affected, it can disrupt ear health and increase the risk of hearing loss.

Let’s Clear the Air: Myths vs Facts

Misinformation around tobacco often makes quitting harder. Here are a few common myths:

1. I only smoke occasionally, so it’s safe

Even occasional smoking increases heart and lung risks – there’s no safe level.

2. Quitting now won’t help after years of smoking

The body begins healing within hours, regardless of how long you’ve smoked.

3. Light cigarettes or vaping are safer

Both still expose you to harmful substances and are not risk-free.

4. I can quit anytime I want

Tobacco creates both physical and psychological dependence, making quitting challenging.

5. Second-hand smoke isn’t harmful

Passive smoking can seriously affect the health of those around you, especially children. .
