What causes pulmonary embolism?

Pulmonary embolism is caused by a blockage of the pulmonary artery or its branches by an embolus. Common symptoms include shortness of breath, coughing, and fainting. In general, pulmonary embolism may be caused by factors such as genetic predisposition, excessive obesity, pneumonia, nephrotic syndrome, or coronary atherosclerotic heart disease. It is recommended to seek medical attention promptly, identify the underlying cause, and undergo symptomatic treatment under a doctor's guidance. Specific analyses are as follows:

1. Genetics: Individuals with a family history of pulmonary embolism may be affected by genetic variations, making them more susceptible to developing the condition. It is important to adopt healthy lifestyle habits and have regular hospital check-ups to reduce the risk of illness.

2. Excessive obesity: A lack of physical activity and long-term consumption of high-fat foods can lead to excessive body weight, which typically slows down blood circulation and promotes platelet aggregation, potentially triggering pulmonary embolism. Regular exercise such as running or swimming should be maintained to keep body weight within a healthy range.

3. Pneumonia: Usually caused by pathogenic microorganism infections or immune system damage, if not treated promptly, prolonged inflammatory stimulation may lead to pulmonary embolism, often accompanied by symptoms such as cough, sputum production, and fever. Patients may follow medical advice to use medications such as acyclovir capsules, cefalexin and trimethoprim tablets, or ribavirin tablets for treatment.

4. Nephrotic syndrome: This condition may be associated with infections or T-cell immune dysfunction, and is prone to thrombotic complications that could lead to pulmonary embolism. Symptoms such as proteinuria and edema may also occur. Patients should follow medical instructions and use medications such as furosemide injection, losartan potassium and hydrochlorothiazide tablets, or cyclosporine soft capsules for treatment.

5. Coronary atherosclerotic heart disease: The development of this disease is related to genetic factors and lipid abnormalities. It may lead to dislodgement of thrombi from the right cardiac chambers, which then travel into the pulmonary artery and cause pulmonary embolism, commonly presenting with chest pain and tightness. Patients may take prescribed medications to improve their condition, including simvastatin dispersible tablets, atorvastatin calcium tablets, and isosorbide dinitrate tablets.

In daily life, it is advisable to maintain a light diet, avoid smoking and alcohol, and refrain from eating high-fat, high-calorie foods such as fatty meats and fried chicken, which will better support recovery.
