I often feel shortness of breath. Why?

Nowadays, people may sometimes feel sudden breathlessness and find breathing particularly difficult in their daily lives. This situation is not experienced by just a few people. I believe that most people have experienced similar situations. So what are the specific symptoms of breathing difficulties? Some may just feel a little chest tightness, but it is not serious; some may be that breathing in and out is extremely difficult, as if there is a stone pressing on our chest; some may be that the oxygen we breathe in does not seem to be fresh, and is not enough to ensure our life activities. When these situations occur frequently, it will have an impact on your health and should be taken seriously. Let's take a closer look at why you often feel difficulty breathing.

Breathing difficulties may be caused by:

1. Pulmonary dyspnea

1. Inspiratory dyspnea: It can be seen in diseases such as laryngeal edema, diphtheria, and laryngeal cancer. It is characterized by inspiratory dyspnea, with a slight wheezing sound during inhalation, often accompanied by hoarseness and aphonia. The general manifestation is that inhalation is extremely strenuous. In severe cases, the "three-depression sign" will appear, that is, the suprasternal fossa, supraclavicular fossa, and infraclavicular fossa are obviously sunken during inhalation, which may be accompanied by a dry cough and high-pitched inspiratory laryngitis.

2. Expiratory dyspnea: It can be seen in acute bronchiolitis, bronchial asthma, emphysema, etc., due to weakened elasticity of lung tissue and spasm of small bronchi. Bronchiolitis is often accompanied by cough, sputum, etc. Bronchial asthma is a recurring dyspnea, generally manifested as extra effortful exhalation, prolonged and slow exhalation or double exhalation, often accompanied by dry rales.

3. Mixed dyspnea: It can be seen in diseases such as chronic obstructive pulmonary emphysema and pulmonary edema. It is caused by a reduction in the lung respiratory area. Its characteristics are identified according to the primary disease.

2. Cardiac dyspnea Dyspnea is one of the main symptoms of heart failure . Patients have severe heart disease and present with mixed dyspnea, which is relieved when sitting or standing and aggravated when lying down. Patients with breathing difficulties should pay attention to the following:

1. There are many causes of breathing difficulties, and it may also be a problem with the environment. Therefore, you should go to open places more often and pay attention to keeping the indoor air circulating. At the same time, do not often wear tight clothes.

2. For breathing difficulties, treatment is not the primary consideration. The key is to find out exactly what disease is causing the breathing difficulties, so that targeted treatment measures can be taken. Some severe symptoms can usually be treated with medication. From the above, we can see that when symptoms of breathing difficulties occur, they should not be ignored. Breathing difficulties may be a manifestation of underlying diseases, so you should consult a doctor in time to understand the situation.
