Diseases Caused by Air Pollution
Air is the most important aspect of life because oxygen is present inside it. Not even a plant, an animal or human being can survive without it. Nowadays the air is polluted and because of it, many diseases have taken place in human lives.
It is caused by the high levels of air pollution present in the air. The person who has this problem, the inside walls are swollen which causes airways to be narrower. Hence, less air passes through. The mucus is produced due to which the airway becomes narrower. Asthma attacks mild, moderate, severe and very severe. A person who is having asthma should know how to control it and should take advises time to time.
This cancer is related with lungs. They are made of elastic tissue filled with implicating networks of tubes and sacs carrying air, and with blood vessels carrying blood. It is increasing year by year due to increase in the pollution. The prior reason is smoking but it can be caused to that person who has never done it. Lung cancer develops most often in scarred chronically diseased lungs. Moving further, the other reason is underlying inflammatory pulmonary diseases such as pulmonary fibrosis or alpha-1 antitrypsin deficiency.
COPD(Chronic Obstructive Pulmonary Disease)
Chronic Obstructive Pulmonary Disease (COPD) is a kind of obstructive lung disease in which the airflow is poor. There is a difficulty in shortness of breath and due to which sometimes you feel very tired. There are two main forms of COPD. A) Chronic bronchitis, which involves a long-term cough with mucus. B) Emphysema, which involves damage to the lungs over time. More than 100,000 people in the United States alone die from Chronic Obstructive Pulmonary Disease.
Emphysema really damages the air sacs (alveoli) in lungs. Your lungs’ alveoli are clustered like bunches of grapes. In emphysema, the inner walls of the air sacs weaken and eventually rupture — creating one larger air space instead of many small ones. This reduces the surface area of the lungs and, in turn, the amount of oxygen that reaches your bloodstream.
Giardiasis is an infection of your small intestine. It’s caused by a microscopic parasite called Giardia lamblia. Giardiasis spreads through contact with infected people. Pet dogs and cats also frequently contract giardia. You can also get giardiasis by eating contaminated food or drinking contaminated water.
For those who do get sick, signs and symptoms usually appear one to three weeks after exposure and may include:
a) Watery, sometimes foul-smelling diarrhoea that may alternate with soft, greasy stools b) Fatigue or malaise c) Abdominal cramps and bloating d) Gas or flatulence e) Nausea and f) Weight loss
