What causes dyspnea, and what causes dyspnea?

1. Respiratory diseases.

1) Airway obstruction: such as inflammation, edema, stenosis or obstruction caused by tumors or foreign bodies of larynx, trachea and bronchial asthma, chronic obstructive pulmonary disease, etc.

2) Lung diseases: such as pneumonia, lung abscess, tuberculosis, atelectasis, pulmonary congestion, pulmonary edema, diffuse pulmonary interstitial disease, bronchiolar alveolar carcinoma, etc.

3) Chest wall, thoracic cavity and pleural cavity diseases: such as chest wall inflammation, severe thoracic deformity, pleural effusion, spontaneous pneumothorax, extensive pleural adhesions, tuberculosis, trauma, etc.

4) Neuromuscular diseases: such as polio lesions involving the cervical spinal cord, acute polyradiculoneuritis and myasthenia gravis involving respiratory muscles, and drugs causing paralysis of respiratory muscles.

5) Diaphragmatic dysmotility: such as diaphragmatic paralysis, large amount of ascites effusion, huge abdominal tumor, gastric distension and the end of pregnancy.

2. Circulatory diseases.

It is common in left and right heart failure, cardiac tamponade, pulmonary embolism, and primary pulmonary hypertension due to various causes.

3. Poisoning. It is caused by various poisonings, such as diabetic ketoacidosis, morphine poisoning, organophosphate insecticide poisoning, hydride poisoning, nitrite poisoning and acute carbon monoxide poisoning.

4. Neuropsychiatric diseases.

For example, cerebral hemorrhage, brain trauma, brain tumor, encephalitis, meningitis, brain abscess and other craniocerebral diseases cause respiratory center dysfunction and dyspnea caused by mental factors, such as hysteria.

5. Blood diseases.

It is common in severe anemia, methemoglobinemia, sulfide hemoglobinemia, etc.

Common diseases. Bronchial asthma, chronic obstructive pulmonary disease, pneumonia, tuberculosis, atelectasis, bronchiolar alveolar carcinoma, chest wall inflammation, pulmonary embolism, primary pulmonary hypertension, diabetic ketoacidosis, morphine poisoning, organophosphate insecticide poisoning, hydride poisoning, acute carbon monoxide poisoning, cerebral hemorrhage, traumatic brain injury, brain tumor, encephalitis, meningitis, anemia, methemoglobinemia, hemoglobinemia sulfide, etc.

Causes of dyspnea: Patients with chronic obstructive pulmonary disease (COPD) will have dyspnea due to impaired ventilation and ventilation of their lungs; In patients with airway obstruction, dyspnea may occur; Patients with lung tumors, which cause dyspnea due to poor ventilation; In patients with heart disease, it is difficult to breathe due to angina caused by myocardial ischemia.

Dyspnea is usually divided into clinical manifestations due to respiratory, cardiovascular, and other causes. Respiratory diseases commonly include airways obstruction of the lungs, such as lung infections, tumors, bronchiectasis, etc. Airway obstruction includes obstruction caused by foreign inhalation or airflow limitation due to the lesion of the airway itself.

Disorders of the chest wall, thoracic cage, and pleura, as well as diaphragmatic disorders that limit movement, can cause dyspnea. The common causes of cardiovascular disease are heart failure, constrictive pericarditis, etc., and in general, there is an underlying cardiovascular disease. Others, such as obesity, acidosis, acute infection, blood diseases, etc., can also lead to dyspnea and even respiratory failure.

When dyspnea occurs, it is necessary to seek medical attention in time, and distinguish the cause of dyspnea according to clinical manifestations and preliminary physical and chemical examinations.

Dyspnea can be seen in multisystem disorders, most commonly of the respiratory system. For example, inflammation of the trachea and bronchi, edema, foreign bodies or tumors, pneumonia, lung abscess, tuberculosis, interstitial pneumonia, and inflammation of the pectoral muscles, thoracic deformity, pleural effusion, pneumothorax, or myasthenia gravis involving respiratory muscles, and poliomyelitis involving the cervical spinal cord, diaphragm paralysis, gastric distension, etc.

It can also be seen in circulatory disorders, such as cardiac tamponade, pulmonary hypertension, and heart failure.

Toxic factors, diabetic ketoacidosis, organophosphate poisoning, acute carbon monoxide poisoning.

Neuropsychiatric diseases can also cause cerebral hemorrhage, traumatic brain injury, brain tumor, encephalitis and some blood diseases, such as severe anemia, methemoglobinemia, etc.

A dyspnea can not be generalized or a word, you see what the situation causes the best advice, you are going to the hospital to see something else, because of some diseases that cause this delay and delay.

The causes include respiratory diseases such as bronchial asthma, tracheal tumors, tracheal foreign bodies, etc. Diseases of the cardiovascular system such as heart failure, cardiac tamponade, constrictive pericarditis, etc.

There are many reasons for this: for example, cardiopulmonary problems, and some aspects of the body that can affect breathing problems in case of special pain, and the lack of oxygen in the environment can also affect breathing.

Feeling that it is difficult to breathe can be seen in many diseases. For example, many respiratory diseases may cause dyspnea, such as chronic obstructive pulmonary disease, bronchial asthma, bronchiectasis, pleural effusion, pneumothorax, pulmonary interstitial fibrosis, pulmonary embolism and other related diseases.

In addition, other systemic diseases may also cause breathing difficulties, such as cardiac insufficiency is a common cause. In addition, there are other conditions such as anemia that may cause the patient to feel difficulty breathing, and even mental factors may cause the patient to have difficulty breathing.
