PPulmonology is a branch of medicine that deals with the treatment of diseases of the respiratory tract. Chronic Obstructive Pulmonary
Disease (COPD) is, today, among the most common diseases that has
taken on epidemic proportions worldwide. Other lung related chronic
ailments like asthma and allergic rhinitis are also fast becoming major
issues, particularly in cities because of rising pollution.
Some common Respiratory Diseases include:
Chronic Obstructive Pulmonary Disease
COPD is an obstructive lung disease where the airways
become damaged, causing them to narrow, leading to a
limitation of the flow of air to and from the lungs, causing
shortness of breath (dyspnoea). COPD is usually caused by
noxious particles or gas, most commonly from tobacco
smoking, which triggers an abnormal inflammatory
response in the lung.
Acute bronchitis occurs when the inner walls that line the
main air passageways of our lungs become inflamed.
Bronchitis often follows a respiratory infection such as a
cold, which if left untreated, can lead to Chronic Bronchitis.
Chronic bronchitis is defined in clinical terms as a cough with
sputum production on most days for 3 months of a year,
for 2 consecutive years. Inflammation causes a thickening
of the walls and results in narrowing of the airways. As a
consequence of these changes air flow becomes limited.
An incessant cough accompanied by a wheezing sound is
usually indicative of Asthma. This is an inflammatory lung
disease that is usually brought on by triggers, such as air
pollution, tobacco smoke, factory fumes, cleaning solvents,
infections, pollens, certain foods, cold air, exercise, chemicals
and medications. Asthma, apart from the juvenile form that
usually cures by itself by 23-24 years of age, is a condition that
needs lifelong treatment.
Respiratory tract infections
Infections can affect any part of the respiratory
system. The most common among these is Rhinitis,
which is often mistaken for common cold. A
perpetually blocked or runny nose may be
indicative of Rhinitis. It is caused by inflammation
in the nasal passage. Pneumonia is a lower
respiratory tract infection that is caused by
bacteria. If left untreated it can develop into lung
abscess or may spread to the pleural cavity
A collection of fluid in the pleural cavity is known
as a pleural effusion. This may be due to fluid
shifting from the bloodstream into the pleural
cavity due to conditions such as congestive
heart failure and cirrhosis, or it may be due to
inflammation of the pleura itself caused due to an
infection, tuberculosis and other conditions.
