Symptoms of blocked lungs

The harm caused by blockage of the lung duct is very serious. The most common cause is chronic obstructive pulmonary disease. Through investigation, it is found that there are many people with chronic obstructive pulmonary disease in my country. This is also a relatively common chronic disease. It has a great impact on the health of patients and often causes difficulty breathing, especially after exercise. It is also easy to cause chest pain and coughing up blood in severe cases. In this case, attention should be paid to timely treatment. Good maintenance in daily life is also very important.

Symptoms of blocked lungs

1. Difficulty breathing:

The most common early symptom of pulmonary embolism is dyspnea, which often occurs after exercise. Dyspnea may be related to respiratory and circulatory dysfunction. Breathing difficulties may be mild or severe. Sometimes they disappear quickly and recur after a few days or months. When mild breathing difficulties occur, they should be taken seriously.

2. Chest pain:

In addition to difficulty breathing, the early symptoms of pulmonary embolism are chest pain. A large number of people will have this symptom, which will occur suddenly, is mostly related to breathing, and worsens when coughing. Larger emboli may cause severe, crushing pain that is also located behind the sternum, difficult to tolerate, and radiates to the shoulder and chest.

3. Coughing and coughing up blood:

Patients with pulmonary embolism may also suffer from cough in the early stages, which is mostly dry cough, or with a small amount of white sputum, accompanied by wheezing. In severe cases, symptoms of coughing up blood may occur, indicating the occurrence of pulmonary infarction. 4. Abdominal pain: Pulmonary embolism sometimes causes abdominal pain, which may also be related to irritation of the diaphragm. Some patients may experience syncope. The main cause of syncope is insufficient blood supply to the brain caused by massive pulmonary embolism.

6. Syncope:

The main cause of syncope in patients with pulmonary embolism is insufficient blood supply to the brain caused by more than 50% blockage of blood vessels. This may also be the only or earliest symptom of chronic thrombotic pulmonary hypertension and should be taken seriously. Most cases are accompanied by hypotension, right heart failure and hypoxemia. Although small emboli can cause syncope, large emboli are still considered the main cause of syncope.
