What are lung diseases?

Lung disease has become the most common disease that threatens us humans. There are many types of lung diseases, the most common ones are tuberculosis and lung cancer. There are already many people with lung diseases, especially those who smoke frequently and those who are often exposed to oil fumes. They are very likely to suffer from lung diseases. In our daily lives, we should know more about lung diseases, know what lung diseases there are, and do a good job in preventing lung diseases.

Lung disease has become a very common disease. Everyone should know what lung diseases there are. There are many types of lung diseases. Some lung diseases are not serious, but if it is diagnosed as lung cancer, it must be taken seriously. This will also threaten life safety and must be actively treated.

1. Tuberculosis

A disease characterized by night sweats, coughing and gradual weight loss as the main symptoms.

2. Lung cancer

What are lung diseases? A disease with chest pain, shortness of breath, cough, hemoptysis and fever as the main clinical manifestations.

3. Asthma

Clinically, the symptoms include wheezing in the throat, rapid and difficult breathing, and in severe cases, the patient cannot lie flat while gasping for breath.

Internal causes of lung disease

1. Genetic factors: Epidemiological research results suggest that susceptibility to lung disease is related to genes, but lung disease is definitely not a single gene disease, and its susceptibility involves multiple genes. The only certainty at present is the varying degrees of alpha-antitrypsin deficiency. Other genes such as glutathione S-transferase gene, matrix metalloproteinase tissue inhibitor-2 gene, heme oxygenase-1 gene, tumor necrosis factor-a gene, interleukin (IL)-13 gene, IL-10 gene, etc. may also have a certain relationship with the onset of COPD.

2. Airway hyperresponsiveness: The results of epidemiological studies at home and abroad have shown that people with increased airway hyperresponsiveness have a significantly increased incidence of lung disease, and the two are closely related. Individuals whose lungs develop or grow poorly due to various reasons during pregnancy, neonatal period, infancy or childhood are prone to lung disease in adulthood.

3. A large number of epidemiological studies around the world have confirmed that smoking is the primary risk factor for lung cancer. Experts point out that 70% to 80% of lung cancer is related to smoking (including passive smoking), and other related factors include: radiation exposure factors, environmental or occupational exposure factors, genetic or familial factors, etc.

The symptom of lung disease is usually coughing. Everyone should know what lung diseases are, especially male friends who usually smoke. People who smoke have a high chance of developing lung disease. Some people's lung disease is not taken seriously and it develops into the most serious condition, which is lung cancer. If you have lung cancer, it will be too late to regret it. Therefore, we should actively prevent lung disease.
