Always hold your breath, can't breathe ... Is it heart disease or lung disease? Listen to the doctor's professional interpretation.

In life, we often meet people around us who hold their breath and can't breathe, which makes people look worried. We can't live without the supply of oxygen. Once we have difficulty breathing, our bodies will be deprived of oxygen. If the "hypoxia" lasts for a short time, it will also cause short-term slight discomfort; If it lasts for a long time, it will seriously affect our health and sometimes threaten our life safety. Many friends want to know, what is the main cause of dyspnea?

The lung is the breathing organ in the palm, and the heart is responsible for transporting oxygen. Friends naturally think that the problem of dyspnea is either a heart problem or a lung disease. In fact, the causes of dyspnea are far more than heart disease and lung disease. In most cases, the occurrence of dyspnea may be just a physiological reaction, which is not directly related to physical health. For example, after strenuous exercise, or traveling to high altitude areas, or encountering ultra-high temperature weather, or being in an environment with serious air pollution, a person will have poor breathing. If someone has had difficulty breathing for these reasons, then preventive measures should be taken in advance to avoid similar situations as much as possible.

If the above physiological reasons are excluded, dyspnea may be an early warning signal of some diseases. In daily life, patients with fever are more prone to shortness of breath. When the body is hot, the metabolic level will rise, which will consume a lot of oxygen and cause symptoms of dyspnea. It is for this reason that patients with fever need more rest, less exercise and proper nutrition. When a fever patient feels suffocated, he can also take a deep breath and relax his body to relieve this discomfort. It is worth noting that fever is often caused by infectious diseases. If the body temperature exceeds 38.5 degrees Celsius or the low fever lasts for more than 3 days, you should go to the hospital in time.

Severe asthma and poor breathing are probably caused by lung disease or heart disease. It is difficult for ordinary people to clearly distinguish the dyspnea caused by these two diseases from the symptoms. Even professional doctors need reliable test results to make a diagnosis. In most cases, the patients with dyspnea caused by lung diseases or heart diseases are older, often complicated with various diseases, and cardiogenic diseases and lung diseases will also affect each other, which is also an important reason why it is difficult to distinguish the causes. Generally speaking, we can pay attention to the following two points:

1. People with basic cardiovascular diseases, such as hypertension, diabetes, coronary heart disease or cerebrovascular disease, are more likely to have cardiogenic dyspnea; People with basic respiratory diseases such as chronic obstructive pulmonary disease, chronic bronchitis and asthma are more likely to have pulmonary dyspnea.

2. With the change of exercise intensity and limb posture, dyspnea will also change, and cardiogenic dyspnea is more likely; If it has little to do with movement and posture, it is more difficult to inhale, and it is more likely to have pulmonary dyspnea.

In any case, once someone has symptoms of dyspnea, we should not underestimate it. There must be a reason. We found that many people also have shortness of breath when they are nervous. If the cause of dyspnea can be preliminarily judged, targeted first aid measures can be taken. Keeping calm, encouraging patients to keep breathing rhythm and making emergency calls in time are three things that everyone must do.
