Why do you feel like coughing when you breathe? Be careful of three diseases

Many people don’t know what it means when breathing feels like coughing. Some people think it is a simple cold. In fact, long-term breathing feels like coughing may be caused by some respiratory diseases, such as upper respiratory tract infection. This condition may also be related to some bacteria and viruses.

1. Tracheitis

Tracheitis is an inflammatory change in the tracheal and bronchial mucosa caused by infectious or non-infectious factors, with increased mucus secretion. The main clinical features are long-term cough, sputum or wheezing. The early symptoms of this disease are mild, mostly occurring in winter and relieved after the spring, and the course of the disease is slow, so people do not pay attention to it. When the disease progresses to the late stage and obstructive pulmonary emphysema occurs, lung function is damaged, which has a great impact on health and labor force. This disease is one of the common and frequently occurring diseases in China. Decades of clinical data show that the onset age is mostly over 40 years old, and the incidence rate of smokers is significantly higher than that of non-smokers. In China, the incidence rate in the north is higher than that in the south, and the incidence rate in rural areas is slightly higher than that in urban areas.

2. Bronchitis

Bronchitis refers to nonspecific inflammation of the trachea, bronchial mucosa and surrounding tissues. Most of them are caused by bacterial or viral infections. According to epidemiological surveys, the main ones are rhinovirus, syncytial virus, influenza virus and rubella virus. The more common bacteria are pneumococci, hemolytic streptococci, staphylococci, influenza bacilli, salmonella and diphtheria bacteria. In addition, sudden changes in temperature, dust, smoke and irritating gases can also cause bronchitis. Clinically, it is characterized by cough, sputum or wheezing and recurrent attacks. It is divided into chronic bronchitis and acute bronchitis. The main symptoms of acute bronchitis are runny nose, fever, cough, and sputum, as well as hoarseness, sore throat, and mild friction pain behind the sternum. In the early stage, the sputum is small and sticky, and then becomes purulent. Irritations such as smoke and cold air can make a cough worse. The main symptom of chronic bronchitis is long-term cough, especially the cough worsens in the morning and evening. If secondary infection occurs, the patient will have fever, chills, and cough with purulent sputum. Clinical data show that winter is the peak season for this disease.

3. Tuberculosis

Tuberculosis is a chronic infectious disease caused by Mycobacterium tuberculosis that can affect multiple organs throughout the body, but pulmonary tuberculosis is the most common. The pathological characteristics of this disease are tuberculous nodules and caseous necrosis, which are prone to form cavities. Clinically, it is mostly a chronic process, but in a few cases, the disease may develop acutely. There are often systemic symptoms such as low-grade fever and fatigue, and respiratory manifestations such as cough and hemoptysis.
