What are the symptoms of asthma? Cough is normal for normal people, but for asthma patients, cough may be a precursor to the attack. Therefore, we should seriously understand asthma. Let's take a look at the symptoms of asthma.

What are the symptoms of asthma 1 asthma? Everyone knows, so what do you know about asthma? For example, what is it like when asthma attacks? How many conditions can asthma be divided into? What are the specific symptoms of asthma? In fact, there are still many things to learn to understand asthma.

During asthma attack, dyspnea can be more serious, which makes patients feel anxious. Patients with severe attacks can only say a few words, so they must stop talking and breathe. Symptoms are light and heavy, and change with time, which is also the characteristic of asthma; That is, the symptoms of all asthma patients change and fluctuate with time.

For patients who have not had any asthma symptoms for weeks or months, they can be called intermittent asthma patients, and for patients whose asthma symptoms are not completely controlled or will appear every few days, they can be called persistent asthma patients.

The change of asthma symptoms may have a circadian rhythm (nocturnal asthma), which depends on whether it is caused by other organ dysfunction (such as cardiogenic asthma and gastroesophageal reflux) or by external and environmental factors. Not all asthma patients will have the above five symptoms when they are acute aggravated. Sometimes cough can appear as the only symptom of asthma patients, while many patients can have dyspnea and wheezing, but there is no obvious chest tightness, cough or expectoration at the same time.

In patients with chronic asthma, there may be no other symptoms at night, but only cough symptoms, which also suggests that the condition has not been completely controlled. Most asthma patients can recall the inducing factors that lead to the aggravation of their illness when asking about their medical history, especially after giving some hints. The lung function test results of patients will also change. In patients with intermittent asthma, the lung function test results can be normal in the asymptomatic period. During the severe attack of asthma, some patients show that they can't speak sentences, their chests are excessively dilated, and they often can't lie flat and sweat profusely. These are also common manifestations of severe asthma patients, and some severe patients often rest with their hands and arms on the table in front of them, similar to those of COPD patients.

In addition, the patient's respiratory motility and tachycardia can be seen at the same time, and the auxiliary respiratory muscles can be seen to participate in respiratory movement, and the patient can be found to have strange pulses when measuring blood pressure. Wheezing sounds and dry rales (low-pitched wheezing sounds) can be heard in both lungs of patients, and wheezing sounds with multiple frequencies are heard, suggesting that wheezing sounds come from different parts of the lungs. Common diseases associated with asthma include eczema (atopy) and nasal polyps.

What are the symptoms of asthma? 2 Symptoms of asthma are:

Precursor symptoms, before the onset of acute asthma caused by allergens, often have catarrhal symptoms of nose and mucosa, such as sneezing, runny nose, itchy eyes, tears, dry cough, chest tightness and so on.

Main symptoms:

First, wheezing and dyspnea are typical symptoms of asthma. The onset of wheezing is often sudden, and dyspnea is expiratory, which is characterized by short inspiratory time and long expiratory time. Patients feel that it is hard to exhale, but some patients will feel that both exhalation and inhalation are hard.

Second, cough and expectoration. Cough is a common symptom of asthma. Due to airway inflammation and bronchospasm, dry cough is often a precursor of asthma. When asthma attacks, the symptoms of cough and expectoration are alleviated, mainly wheezing. At the end of asthma attack, bronchospasm and airway stenosis are relieved, and when a large amount of airway secretions need to be discharged, cough and expectoration may be aggravated, and a large amount of white foam sputum may be coughed up. There are some asthma patients whose acute attack is mainly characterized by irritating dry cough without obvious wheezing symptoms. This part of asthma is called cough variant asthma.

Third, chest tightness and chest pain. When asthma attacks, patients may feel chest tightness and chest tightness. If asthma attacks are severe, it may be related to excessive fatigue or strain of respiratory muscles. Sudden chest pain should consider the possibility of spontaneous pneumothorax.
