What are the early symptoms of pneumonia?

Pneumonia is a common disease. There are many kinds of pneumonia. For example, some children may get pneumonia, and children's pneumonia also needs timely treatment. Many adults may also suffer from pneumonia. We need to know the early symptoms of pneumonia in order to find, diagnose and treat it in time. So, what are the early symptoms of general pneumonia?

1, fever

Due to the stress reaction of inflammation in the body, once infected with pneumonia, the early body temperature will rise rapidly, lasting 39-40℃. At the same time, the body will be accompanied by symptoms such as joint pain and headache.

2, cough and phlegm

Cough phlegm is one of the early symptoms of pneumonia, which is a protective reflex of the body and can promote the discharge of phlegm and foreign bodies. Therefore, when the lungs are infected, there is generally a feeling in the throat, which will cause a cough. It will be white phlegm at first. With the further aggravation of pneumonia, there will be blood sputum, pus sputum and so on.

3, chest pain

Patients with early pneumonia will also have chest pain, which is caused by lung inflammation involving chest wall tissue. Its main manifestations are: occasional or persistent chest pain, aggravated walking or coughing pain, and severe radiation pain in the back or stomach.

4, chest tightness

When the lung is infected, the lung function is weakened, resulting in insufficient ventilation, which can not meet the body's demand for fresh oxygen, making patients feel chest tightness and shortness of breath.

5. Loss of appetite

Most pneumonia is caused by lovely virus. Because the upper respiratory tract infection spreads to the abdominal cavity, causing gastrointestinal discomfort, abdominal pain, diarrhea, loss of appetite and other symptoms, so there will be loss of appetite in the early stage of pneumonia.

6. Classification of pneumonia

1, according to pathological classification

According to pathological anatomy, pneumonia can be divided into lobar pneumonia, bronchopneumonia, part-time pneumonia and bronchiolitis. In addition, due to the different organ maturity of different systems in children. And it has certain characteristics in immunity and reactivity. When the body is stimulated by etiology, the case reaction is often only due to age, so it is also pneumonia, mainly manifested as bronchopneumonia in infants and lobar pneumonia in adults.

2, according to the cause of classification

Etiological classification is also called pathogen classification. With the development of microbiology research, most pathogens of pneumonia have been identified, which can be divided into bacterial pneumonia, viral pneumonia, fungal pneumonia, mycoplasma and chlamydia pneumonia, spirochete and rickettsia pneumonia, protozoan pneumonia and aspiration pneumonia.

In addition, the pathogens causing pneumonia in children are different in different regions and different periods.

3, according to the course of classification

According to the incidence and the length of the disease course, it can be divided into acute pneumonia (the disease course is within 1 month), persistent pneumonia (the disease course is within 1-3 months) and chronic pneumonia (the disease course is over 3 months).

In addition, most childhood pneumonia is acute pneumonia.

4. Classification by disease

According to the clinical manifestations, the disease can be divided into steam pneumonia (mainly respiratory symptoms) and severe pneumonia (with serious complications or overheating or hypothermia). With the improvement of living standard and medical and health level, the incidence of severe pneumonia is decreasing year by year.
