10 Diseases Caused By Smoking You Never Knew

Do you know that smokers are liable to develop life-threatening diseases than non-smokers? Smoking kills but before it does; it terminates the life of the smoker in a gradual and progressive way. Smoking causes damage to nearly every organ of the body. It is responsible for a great number of diseases. Here are 10 diseases caused by smoking you should know:

1.Oropharyngeal Cancer

This is cancer of the mouth and throat. The tobacco smoke from cigars and cigarettes causes abnormal growth of cells and tissues in the mouth and throat. It can progress down to the stomach. Smoking can cause cancer in other organs like the oesophagus, lungs, kidney and bladder. American Cancer Society says that cancer can affect the voice box, lips, inner surface of the lips, cheeks and gums. Oral tobacco products (snuff or chewing tobacco) are linked with cancers of the cheek, gums, and inner surface of the lips. Using oral tobacco products for a long time poses an especially high risk. These products also cause gum disease, destruction of the bone sockets around teeth, and tooth loss.

2.Cataracts

This is an ophthalmological condition that occurs when the natural lens of the eye becomes opaque. It can lead to loss of vision. Cataracts are the leading cause of blindness in the world, according to the Association for Research in Vision and Ophthalmology. Smokers significantly increase their risk of developing cataracts compared to non-smokers.

3. Oesophageal Cancer

This is cancer of the throat. Squamous cell carcinoma usually replaces the normal cells and tissues of the oesophageal tract. Therefore, it affects the lining of the organ and surface of the skin. Doctors link these changes to oral products of tobacco and cigarettes when smoker chew or snuff them. The National Cancer Institute states that smoking increases the chances of developing oesophagal cancer.

4. Erectile Dysfunction

Many studies find that smoking is a major factor in erectile dysfunction. Smoking causes plaque buildup in the arteries (atherosclerosis) which cause narrowing of the blood vessel and therefore obstructs blood flow to the penis. This makes it difficult to expand for erection. In one study, men who smoke more than 20 cigarettes a day had a 60% higher risk of developing erectile dysfunction.

 

5. Lung Cancer

Smoking tobacco products can dramatically increase chances of developing lung cancer. This causes mutation in the normal cells and tissues of the lungs which result in inflammatory processes. It is followed by hardening of the bronchial tree. This overall process affects the alveoli(gaseous exchange of oxygen and carbon dioxide takes place) leading to impaired lung function. According to the American Lung Association, men smokers are 23 times more likely to get lung cancer and women smokers are 13 times more likely. Nonsmokers are also at risk of developing lung cancer. A nonsmoker exposed to secondhand smoke has a 20-30% higher risk of developing lung cancer, and secondhand smoke causes 7,330 deaths a year.Type 2 Diabetes

 

6. Type 2 Diabetes

Diabetes is a group of metabolic diseases that occurs when the sugar level in the blood is more than normal. Around 90% of diabetes cases are type 2 diabetes. Smoking causes the cells of the body to be insensitive to the insulin produced by the pancreas causing more glucose than normal in the blood. The CDC says that smoking is a direct cause of type 2 diabetes. Smokers have a 30-40% increased risk of developing it than non-smokers. People who develop diabetes and continue to smoke are more likely to have trouble controlling their disease. It might lead to increased chances of heart disease, ulcers, infections and amputations.

 

7. Chronic obstructive pulmonary diseases (COPD).

This is the umbrella term for diseases like emphysema and chronic bronchitis. These diseases affect the lower respiratory tract. It is usually progressive and debilitating over time. Smoking is the cause of 9 in 10 COPD related deaths. It causes cough, shortness of breath and wheezing respiration as the damage progresses. Emphysema occurs if tobacco products or cigarette smoke damage the walls between the air sac. This makes it difficult to absorb oxygen and remove carbon dioxide for effective respiration. Smoking during childhood and teenage years slows lung growth and increases the risk of developing COPD.

8. Heart Disease

This is one of the common diseases smoking causes. When you alter aerobic respiration, a progressive degeneration of the heart pacemaker cell eventually causes heart disease. Nicotine in cigarettes reduces the amount of oxygen your heart gets. Hence, it raises your heart rate putting more stress on your heart.  It was discovered that people who smoke are four times more likely to develop heart disease than those who do not. One in 5 deaths from heart disease are related directly to smoking.

9. Stroke

According to the National Stroke Association, smoking causes lack of oxygen in the blood and makes the heart work harder.  Cigarette smoking is a well-established risk factor for stroke.They cause the buildup of plaque (fats, calcium& cholesterol) which blots the blood vessels and obstruct blood flow to the heart. Smoke from cigarettes can damage cells of the heart causing thickening of the blood vessels which hinder blood flow to the brain and cause stroke.

 

10. Gastro oesophagal reflux disease (GERD)

This is a major disorder of the digestive system. It is the reflux of acidic content of the stomach back up the oesophagus. The acidic content is made of pepsin and HCl.

This is a major disorder of the digestive system. It is the reflux of acidic content of the stomach back up the oesophagus. The acidic content is made of pepsin and HCl. Nicortin, a component of tobacco relaxes the lower oesophageal sphincter causing a reflex of the stomach content into the oesophagus.
