Respiratory System Diseases
These include Asthma, Colds, Cough, flu, COPD, emphysema, T.B, pneumonia.
a) Asthma: It is a periodic acute bronchial constriction with difficulty in breathing. It is mostly seasonal and aggravated by allergenic agents like pollen, dust etc.
b) Cold: These are mostly seasonal infections or by climatic change. It is due to inflammation of respiratory tract and caused by many number of viruses. The colds though seem simple which goes off in a week or so are actually the real and wear and tear of respiratory system. The number of colds a person experiences, the faster is drop in lung or respiratory capacity. So one needs to watch on the frequency of colds he suffers. Also, the lifestyle is disturbed due to colds with symptoms like stuffy nose.
c) Cough: Cough is irritating reflex of larynx or bronchi. When a substance or particle enters the system it touches the mucous layers. If the mucous is irritated, it could irritate and lead to cough. Sometimes it is also caused by infectious diseases like tuberculosis, pneumonia etc. This is also a reflex to remove phlegm or mucous from the tract. It can be controlled easily. Yet it can be troublesome in old age, infants as it can pose pressure or pain in the region of heart or throat.
d) COPD: Chronic obstructive pulmonary disorder. Probably the silent yet most fatal disorder of lungs. It is a progressive decrease in lung capacity of a person. The disease makes him unable to perform even simple physical actions. There is severe gushing even on slight physical exertion like standing, walking, climbing stairs etc. to the victim. On sever case it causes lack of oxygen to tissues especially heart, brain and may lead to death. Once diagnosed, the life span of the patient cannot be more than 4-5 years. The main cause is noted to be smoking, air pollution, repeated infections. Yet it can also be due to respiratory infection of bacterial and viral origin.
e) Tuberculosis: A challenging infection to the medical world, tuberculosis could not be eradicated in spite of many year of effort to kill and eradicate the TB. It is caused by bacteria Bacillus calumet Guerin. This is a bacterium with special structures like a calcium shell around it which gives its resistance to TB drugs. It survives in most humans and gets activated due to lack of immunity or mental stress or by direct contact with infectious substance of TB patients. It is spread easily by coughing, phlegm etc from person to person.
Even the treatment is quite harsh as the patient has to consume strong drugs for 6 months to 1 year for complete sterilization from bacteria. If relapsed, the treatment is quite harder as bacteria are better resistant to previous drugs.
f) Pneumonia: It is bacterial infection by streptococcus pneumonia. This causes inflammation, difficulty in breathing etc.
g) Sinusitis: This is the inflammation of mucous layer of nasal tract. The main symptom is stuffy nose. There is difficulty in breathing. The nasal walls are swollen due to engorgement with blood or sometimes there can be polyp or abnormal growth
