What are the symptoms of tuberculosis?
tuberculosis, or TB, is common diseases; Approximately one third of the world's population has been exposed, but most people remain asymptomatic. People who have active tuberculosis infection tend to experience a classic pattern of symptoms and symptoms. Symptoms of tuberculosis usually include a chronic cough that can produce bloody sputum, chest pain, weight loss and fever. The diagnosis of tuberculosis is confirmed on the basis of X -rays of the chest, skin testing and sputum testing, because a person with tuberculosis will have bacteria in their sputum. Sputum is a matter that has been cough up from the lower airways and airways and contains mucus, saliva and any bacteria infecting the lower airways and lungs.
Preliminary diagnosis is usually done on the basis of symptoms of tuberculosis that may be present. The most common symptoms and symptoms of tuberculuosos include chronic cough, blood in sputum, night sweating and fever, chest pain and inexplicable weight loss. PersonThe symptoms will usually be handed over for X -rays of chest, sputum testing and other tests to confirm the diagnosis of tuberculosis.
tuberculosis symptoms are the result of infection m. Bacteria of tuberculosis . The infection begins when the bacteria begin to colonize alveoli of the lungs. Once colonization begins, bacteria are used by immune cells called macrophages, cell types responsible for ingestion and breaking bacterial cells and cellular residues. Macrophages usually do not have problems with digestive bacteria; However, they cannot kill m. Bacteria of tuberculosis they have eaten.
As the infection proceeds, other immune cells, including T cells and B cells, begin to collect around infected macrophages. The theme cells E consist of clusters called granulomas, which are small areas of infected macrophages surrounded by lymphocytes T and B. The immune system is formed by granulomas in cases where immune cells cannot infect infectsI eliminate; Instead of killing pathogen, the immune system moves outside the infected area by surrounding the cell barrier. Within granulomas, lymphocytes secrete cytokines to help kill invasive bacteria.
Classical symptoms of tuberculosis, including bloody sputum, characteristic cough and fever, are caused by this chronic infection. The infection formula may include multiple granuloma cycles, tissue destruction and healing and may take years and even decades unless the disease is treated. As the infection proceeds, the pulmonary tissue is gradually found, which reduces the pulmonary function in the affected individuals. People who are infected with necrotic are more likely to give up infected material.
