How is pneumonia caused?

Generally, pneumonia may be caused by factors such as poor dietary habits, excessive fatigue, long-term smoking, upper respiratory tract infections, or coronary artery atherosclerotic heart disease. It can be treated under a doctor's guidance with general treatments, medication, and other methods. A detailed analysis is as follows:

1. Poor Dietary Habits

Long-term unbalanced nutrition, especially insufficient intake of antioxidants such as vitamins A, C, and E, can reduce immunity and make the lungs more susceptible to pathogenic invasion. It's important to improve dietary habits and maintain a balanced diet.

2. Excessive Fatigue

Chronic overexertion leaves the body in a state of fatigue without sufficient rest. When fatigued, the immune system weakens, increasing susceptibility to pathogens and potentially leading to pneumonia. One should reasonably schedule work and rest periods to avoid excessive fatigue and ensure adequate sleep.

3. Long-Term Smoking

Harmful substances in tobacco, such as nicotine and tar, damage respiratory mucosa and weaken the respiratory system's defense mechanisms, making the lungs more prone to infection and inflammation. One should avoid secondhand smoke and engage in lung-strengthening exercises.

4. Upper Respiratory Tract Infection

Upper respiratory tract infections may be caused by colds or influenza. If not promptly controlled, pathogens may spread to the lungs, causing pneumonia, possibly accompanied by symptoms such as fatigue and muscle pain. Treatment may involve medications like oseltamivir phosphate capsules, isatidis root granules, and amoxicillin capsules, as advised by a physician.

5. Coronary Artery Atherosclerotic Heart Disease

Coronary artery atherosclerotic heart disease is generally caused by plaque buildup on the walls of the coronary arteries, which may lead to circulatory impairment, affecting blood supply and gas exchange in the lungs. This can easily cause pulmonary congestion and edema, creating conditions favorable for bacterial infection and potentially leading to pneumonia. Symptoms may include coughing, sputum production, and difficulty breathing. Patients may be advised by their doctors to use medications such as digoxin tablets, furosemide tablets, and spironolactone tablets for treatment.

Maintaining healthy lifestyle habits is important, including balanced nutrition, avoiding tobacco and harmful environments, boosting immunity, and promptly managing upper respiratory tract infections to prevent worsening of the condition.
