What are the causes of pneumonia? What causes pneumonia?

Different patients have different triggers for pneumonia, and patients need to do it according to their own pneumonia**. Many people may not know what is causing their pneumonia. Let's take a look at the causes of pneumonia introduced by experts.

1. Suffering from some underlying diseases, such as immunodeficiency, diabetes, renal failure, etc., which are common causes of pneumonia.

2. Upper respiratory tract viral infection is also a cause of pneumonia. Viral infections can disrupt the integrity of the bronchial mucosa and affect mucociliary activity, leading to bacterial infection.

3. Coma, anesthesia, and excessive sedatives are prone to foreign body inhalation, causing bacterial infection.

4. The causes of pneumonia are sudden weight loss, hunger, fatigue, drunkenness, etc., which weaken the resistance of the whole body, reduce the phagocytosis of cells, weaken immune function, and lead to the onset of the disease.

1 is older, 2 has low immunity, 3 has a cold, 4 will breathe some dust, 5 did not accept ** in advance, and finally developed pneumonia, all need to go to the hospital for checking.

Infectious factors, if the respiratory tract is infected by viruses or bacteria, it is easy to descend into infection if it is not controlled in a timely and effective manner, and then cause pneumonia. Environmental factors, if you often stay in an environment with poor air quality, it is easy to cause damage to the lungs and cause pneumonia.

Factors that cause pneumonia may be bacterial infections, fungal infections, chronic malnutrition, respiratory tract infections, presence of foreign bodies in the bronchi, immunodeficiency.

In the United States, about 4,005,000 people develop pneumonia each year, and about 55,000 of them die. In the United States, pneumonia, along with influenza, is the 8th leading cause of death and the leading cause of death due to infection. In developing countries, pneumonia is the most common fatal hospital-acquired infection and the most common cause of death.

According to the MSD Manual, anyone can have pneumonia, but you are more likely to develop pneumonia if you have a weakened immune system because:

1.Very young or very old.

2.Are taking certain medications (such as corticosteroids or chemotherapy drugs)3There is human immunodeficiency virus (HIV).

4.Debilitating due to other serious medical conditions (such as diabetes or heart failure)5Spent a long time in the hospital (where I was exposed to a lot of germs) 6Are using a respirator (ventilator).

7.Have severe lung disease, especially chronic obstructive pulmonary disease.

8.Smoking.

Respiratory diseases, bronchial diseases, lung diseases, bacterial infections, influenza, these factors can cause the occurrence of pneumonia.

There are many causes of pneumonia, including weakened immunity, lack of attention to oral hygiene, bacterial infections, respiratory infections, viral and fungal infections, and so on. Most of these patients are caused by bacterial and viral infections, but pneumonia may also be triggered if they are exposed to a highly radioactive environment for a long time or if they are infected with atypical pathogens.

Many people are familiar with the disease pneumonia, most of the disease is children and middle-aged and elderly people, the early symptoms of pneumonia are easily confused with colds, so suffering from the disease, there may be a phenomenon of missed diagnosis, resulting in missing the best time. This will not only make the condition worse, but also increase the difficulty of **, and there are many reasons for pneumonia

What is the main cause of pneumonia? There are many causes of pneumonia, mainly including three aspects: 1. Biological, such as bacterial, viral, mycoplasma, chlamydia, fungal and parasitic infections.

2. Physical, including mechanical lung injury, radiation burns, etc. 3. Chemical, including interstitial pneumonia caused by drugs, pneumonia caused by acid reflux inhalation, etc. Among them, biological infections are the most common, and bacterial infections account for more than 70%.

Bacterial: Pneumonia caused by bacteria invading the lungs, the most common of which are pneumococcus and hemolytic streptococcus A, most of which are caused by these two bacteria.

Caused by viruses: Pneumonia can also be caused by viruses, and among viral pneumonia, the most common is caused by influenza virus, a level 1 megalovirus. Compared with bacterial pneumonia, viral pneumonia is not only more serious, but also relatively more difficult.

Fungal cause: The more common fungi that cause fungal pneumonia are Candida fungi and Aspergillus, which are relatively easy and relatively short.

There are two main causes, both are caused by infection, lung infection caused by viruses and lung infection caused by bacteria.

Pneumonia is an infectious disease of the lungs caused by a variety of pathogens, that is, it is the most common, and the pathogens that cause pneumonia are a variety of bacteria, such as Streptococcus pneumoniae, Haemophilus influenzae and Staphylococcus aureus, in addition, there are some atypical pathogens, such as mycoplasma, chlamydia, Legionella, which can also cause pneumonia, and rare viruses, such as influenza viruses and coronaviruses, can also cause pneumonia, generally against bacteria, against atypical pathogens, We all have the kind of antibiotics with better effects, but viral pneumonia, at present, there are still very few drugs for viral infection, so viral pneumonia will also be more serious, at this time, patients should seek medical treatment in time, especially if the outpatient may not be effective, and be hospitalized in time**.

Causes pneumonia 1Gram-negative bacilli infection.

It is more common, mostly Escherichia coli, Klebsiella, Pseudomonas aeruginosa, influenza bacillus, etc.

2.Infection of pathogenic bacteria in respiratory conditions.

In the elderly, due to the reduced immunity of the body, fungi and anaerobic bacteria often exist in the oropharynx, which can cause pneumonia.

3.Co-infection.

Older people often present with co-infections caused by multiple pathogens due to weakened immune systems. Such as bacteria, viruses, fungi, aerobic bacteria, anaerobic bacteria, etc.

4.Drug-resistant bacteria are on the rise.

Due to the abundant and widespread use of antibiotics, the genes of pathogenic microorganisms are changed and drug resistance is generated, among which gram-negative bacilli are the most prominent.
