What is pneumonia and what it is

Pneumonia is a disease of the lungs or their parts that occurs through the development of acute respiratory infections in them. Consider what pneumonia is. You should also decide which of its forms are typical and which are atypical.

As a rule, pneumonia can be caused by a number of factors, among which the most common is an excessive amount of microorganisms in the lungs such as viruses, bacteria, and even fungi. It is worth making a reservation that typical pneumonia is caused by intracellular pathogens, and all other microorganisms provoke the development of atypical forms of the disease, most often occurring in individuals with reduced immunity. In addition, external factors such as bad habits, mechanical damage to the chest, problems with the immune system, prolonged bed rest, artificial lung ventilation, old age and various oncological diseases also have an active influence on the development of the disease.The pathogens of the disease enter the lungs through blood or through the respiratory tract, which leads to inflammation; very rarely does the disease occur due to changes in the lung cavity.

Signs of pneumonia

The clinical picture of the disease depends on the damage to the lungs and the type of pathogens. Despite this, the main signs of any pneumonia are weakness, fatigue, lack of appetite, muscle pain and cramps, fever with chills, cough with purulent sputum, chest discomfort, cyanosis or pale skin.

What is pneumonia in terms of its atypical formsmycoplasma pneumonia

Depending on the type of pathogens, pneumonia is divided into two large groups: mycoplasmal and segmental.

Mycoplasma pneumonia

This disease got its name from the smallest cells of the cytoplasmic type - mycoplasma, which move freely throughout the body and have good resistance to the action of antibiotics. They provoke atypical pneumonia, since cell growth does not occur in the lungs themselves, but on the surface of the mucous membranes of the bronchi. Then they enter the upper parts of the lungs, causing severe edema.Symptoms of mycoplasma-like pneumonia are persistent cough, severe headaches, and sometimes even fever. It is best to undergo treatment with ambular, since it is very difficult to stop the growth of mycoplasmas on your own. In order to prevent doctors recommend vaccination.

segmental pneumoniaSegmental pneumonia

It is characterized by lesions of individual lung segments with penetration into the diaphragm and sometimes even into the thoracic spine. This type of atypical pneumonia can lead to fibrosis, which significantly delays the clinical course of the disease (up to 4 months). Symptoms are wheezing, purulent sputum with blood elements, difficulty breathing, chest pain. If you do not treat the disease, it will become chronic, which may lead to the development of tuberculosis, heart failure, and even cancer.


Thus, the answer was given to the question of what is pneumonia and how it develops. In order to prevent the occurrence of the disease, you need to lead a healthy lifestyle, strive to strengthen the body and improve immunity.
