What are the symptoms of late-stage pulmonary fibrosis

Late-stage pulmonary fibrosis often occurs in men aged 40 to 50. The most common symptom is that the patient experiences difficulty breathing or difficulty breathing during strenuous activities. Severe cases can lead to loss of labor and death.

1. The symptoms of pulmonary fibrosis are a disease of unknown cause, characterized by diffuse alveolitis and alveolar structural disorder that eventually lead to pulmonary interstitial fibrosis. It can be divided into acute, subacute and chronic types according to the course of the disease. The so-called idiopathic pulmonary fibrosis syndrome is an acute type, while subacute and chronic types are more common clinically. So what are the late symptoms of pulmonary fibrosis? Let us learn about it.

Late-stage symptoms of pulmonary fibrosis

2. Pulmonary fibrosis usually occurs between the ages of 40 and 50, and is more common in men than in women. Dyspnea is the most common symptom of pulmonary fibrosis. In mild pulmonary fibrosis, dyspnea often occurs during strenuous activity and is therefore often ignored or misdiagnosed as other diseases. As pulmonary fibrosis progresses, dyspnea may also occur at rest, and patients with severe pulmonary fibrosis may experience progressive dyspnea. Other symptoms include dry cough and fatigue. Some patients have clubbing and cyanosis. The serious consequences of lung tissue fibrosis lead to changes in the normal lung tissue structure and loss of function. When a large amount of fibrotic tissue without gas exchange function replaces the alveoli, oxygen cannot enter the blood. Patients suffer from difficulty breathing, hypoxia, acidosis, loss of labor, and in severe cases, death.

3. The main symptoms are: ① Dyspnea: exertional dyspnea that progressively worsens, shallow and rapid breathing, nasal wing movements and accessory muscles may participate in breathing, but most people do not sit up to breathe. ② Cough and sputum: There is no cough in the early stage, but there may be a dry cough or a small amount of mucus sputum later. Secondary infection is prone to occur, resulting in mucopurulent sputum or purulent sputum, and occasionally bloody sputum. ③Systemic symptoms may include weight loss, fatigue, loss of appetite, joint pain, etc., which are generally rare. The acute type may be accompanied by fever.

4. Common signs: ① Dyspnea and cyanosis. ②Chest expansion and decreased diaphragm activity. ③ Velcro rales in the middle and lower parts of both lungs are characteristic. ④ Clubbing of fingers and toes. ⑤ Corresponding signs of end-stage respiratory failure and right heart failure.
