Lower respiratory diseases come in various forms and affect people of all age groups. Most respiratory diseases can be controlled by regular medication and lifestyle changes. Sometimes respiratory diseases are a result of genetically inherited problems too. Although in most cases they are a result of external factors.

The most common types of lower respiratory disease include:

Chronic Bronchitis:

In simple terms Chronic Bronchitis is a condition wherein the airways in the lungs get inflamed. It generally falls under the category of Chronic Obstructive Pulmonary Disease (COPD). Chronic bronchitis is usually identified when a person suffers from a constant cough that produces phlegm which lasts for at least three months. The bronchitis in this case may reoccur before the year ends or the next year. This is when it is considered chronic by nature.

Other common symptoms of Chronic Bronchitis include breathlessness, constant wheezing, chest pains, fever, and overall fatigue. Patients usually notice a greenish or yellowish mucus formation every time they cough.

What are the causes of Chronic Bronchitis?

Regular smokers often suffer from Chronic Bronchitis.

Sometimes, weather changes or allergies to certain seasonal plants or pollutants in the air may also lead to Chronic Bronchitis.


Emphysema is another lower respiratory disease that falls under the category of Chronic Obstructive Pulmonary Disease (COPD). The condition is usually brought on when the tissues that support the shape and functions of the lung are destroyed. In simpler terms it is an obstructive disease that generally affects the normal breathing and respiration in a person.

What are the causes of Emphysema?

Smoking and tobacco inhalation is usually considered to be the most common cause of Emphysema. When people suffer from this condition, there is a lack of oxygen in the blood and lungs leading to a build-up of carbon dioxide in the blood eventually.

This may eventually lead to dyspnea.

Constant exposure to air pollutants may also lead to Emphysema eventually.

Sometimes Emphysema may also occur due to aging, especially if a person has always suffered from other respiratory diseases.

People who age may also suffer from the disease due to weakening of the mass in their chest muscles, weakening of bones and cartilage which eventually lead to scarring or damage of tissue too.

Some patients may also suffer from constant breathlessness even when they are not undergoing any physical activity.


is another common lower respiratory disease that affects millions of people. However, it is also one of the few respiratory diseases that are easily manageable.

Asthma is a condition wherein the airways in the lungs are constantly characterized by variable symptoms. It falls under the category of chronic inflammation diseases.

What are the common symptoms of Asthma?

Most people suffer from constant wheezing, difficulty in breathing, tightness in the chest, bouts of coughing. Asthma attacks are generally identified by the extent of the person’s difficulty to breathe.

In most cases patients suffer from attacks due to air pollutants of other triggers, maybe even stress. When a patient suffers from asthma it is advisable to avoid smoking and extreme physical activities.

People who suffer from asthma may also suffer from other health conditions eventually.
