Asbestos Health Effects

Diseases related to asbestos exposure are noticed 15 to 40 years after exposure. Prolonged asbestos exposure can have a lot of damaging health effects which in certain cases prove fatal.

 

Types of Asbestos
Asbestos is a naturally occurring mineral which was widely used in many commercial products for its properties of resistance to heat and chemicals, flexibility, and strength. Asbestos are divided into two main groups – serpentine and amphibole. Chrysotile comes under the serpentine group. Actinolite, anthophylite, amosite, crocidolite and tremolite all come under the amphibole group.

Persons with Maximum Health Risk From Asbestos Inhalation
Asbestos was widely used from the 1940s right through the 80’s. Regulations regarding the use of asbestos were in effect only from the mid 70’s, and became more stringent in the 90’s.

 

Asbestos fibers when dry, can easily get dispersed in the air. Inhalation of these microscopic fibers have got serious health effects, but will not show immediately. It could take anywhere between 15 to 40 years or more for symptoms to show.

Since regulations either never existed a few decades ago, or were not as stringent as they are today, asbestos exposure then was very high. Following are those persons who were at a maximum risk of high asbestos inhalation.

 

— Mine workers
— Those working in asbestos-cement manufacturing plants
— Construction workers
— Plumbers and electricians
— Those involved in renovation of old constructions
— Those working in the auto clutch and brake manufacturing industry
— Auto mechanics (especially those who service clutch and brake assemblies)
— Those involved in ship building
— Those involved in ship breaking for scrap

 

 

Health Effects Due to Asbestos Exposure
Asbestos exposure and inhalation causes three major health effects.

— Asbestosis
— Mesothelioma
— Lung Cancer

Asbestosis
Asbestosis is a chronic and restrictive lung disease. It is caused by inhalation of asbestos particles over prolonged periods of time. Asbestosis takes approximately 15 to 20 years to show its effects.

 
The inhaled asbestos fibers initially damage the cell membranes in the lungs, causing the lung tissues to harden and form scars. This is known as fibrosis.

During the initial stages of disease only the outer lung tissues get scarred, but as the disease progresses, it affects the entire lungs. The hardening of lung tissues make breathing difficult, thus reducing the oxygen intake. Pressure on the lungs increase because of its inability to remove carbon dioxide and replace it with fresh oxygen. This is the reason it is known as a restrictive lung disease.

 

Persons suffering from asbestosis are more prone to develop bronchitis and pneumonia.

Symptoms of Asbestosis may include one or more of the following.

— Shortness of breath
— Difficulty in breathing
— Constant dry cough
— Constant pain in the chest
— Pulmonary hypertension
— Excess phlegm

Mesothelioma
Mesothelioma is a cancer of the pleura (lung lining). Past documented records show that mesothelioma is caused mainly by the inhalation of the crocidolite and amosite variety of asbestos.

 

Mesothelioma takes approximately 30 to 40 years to develop and show its effects. It is one of the most fatal, aggressive and painful cancers, almost always leading to death.

Mesothelioma is mostly restricted to the lungs, but in rare instances it can also occur in the peritoneum (abdominal cavity) in cases where the asbestos fibers reach the stomach or bowel.

 
Symptoms of Mesothelioma may include one or more of the following.

— Shortness of breath which keeps on increasing as the disease progresses
— Extreme difficulty in breathing due to lung compression caused by the disease
— Constant pain in the chest which ranges from mild to severe pain
— Unexplained sudden abdominal swelling and pain
— Unexplained weight loss

Lung Cancer
Cancer of the lung, bronchial tubes and alveoli are the effect of constant long-term asbestos exposure.

 

 

 

Persons who have been exposed to asbestos and also smoked are at the highest risk of developing lung cancer. The combination of asbestos and cigarette smoke in the lungs will in most cases lead to lung cancer.

Symptoms of lung cancer may include one or more of the following.

— Dry, irritating cough
— Increase in sputum production
— Blood mixed with sputum
— Chest pain
— Lung infection

 

Get Medical Help Immediately
If you have been exposed to asbestos in work related issues over the past few decades, chances are that the signs and symptoms of asbestos related disease could show up anytime now. If you notice any of the above mentioned symptoms, do not wait for it to subside naturally. Get medical advice immediately. If an asbestos related disease is detected, you may not live a perfectly normal life, but going onto prescribed medication immediately will not only prolong, but possibly even save your life.
