List of Lower Respiratory Tract Diseases
First on the list of respiratory diseases of the lower respiratory tract system is acute bronchitis. This is an inflammation of the mucous membranes of the bronchial tubes and is caused by bacteria or viruses or by allergens in the air. The common symptoms of acute bronchitis include runny nose, chills, sore throat, and back and muscle pain.
Lung cancer is one of the life-threatening conditions that cannot be left out of a list of respiratory diseases. It begins in the lining of the bronchi and develops over a period of many years. All lung cancers are carcinomas, that is, they begin in the lining or covering tissues of an organ. Once the tumor begins growing, a patient with lung cancer can develop symptoms such as cough, chest pain, wheezing, shortness of breath, and hoarseness. Smoking is responsible for about 90 percent of lung cancer cases.
A chronic lung disease that causes inflammation and narrowing in the airways, asthma is a must-include in a list of respiratory diseases. Symptoms of asthma include wheezing (characterized by a whistling sound while breathing), tightness in the chest, shortness of breath, and coughing. Contact with airborne allergens and genetic factors seem to play a role in the development of asthma.
Another disease in the list of respiratory diseases is pneumonia, which is characterized by an inflammation of the lungs caused by bacteria, viruses, or chemicals. It usually occurs when the body is weakened in some way due to illness, a weak immune system, or old age. Symptoms include shaking, chattering teeth, severe chest pain, high fever, rapid breathing, and a cough that is rust-colored or greenish.
The next condition in a list of respiratory diseases is tuberculosis which is a chronic bacterial infection mostly affecting the lungs. The tuberculosis bacterium spreads through the air, however, for the person to become infected, repeated exposure is usually required. Common symptoms of this disease include a cough that does not go away, loss of weight, fatigue, coughing blood, fever, and night perspiration. The elderly and people with weak immune systems are the most susceptible to get infected by the tuberculosis bacterium.
