Tuberculosis (TB) is a bacterial infection primarily affecting the lungs, but it can also impact other parts of the body. This is often referred to as extrapulmonary TB.
Organs Commonly Affected by Tuberculosis

Lungs: TB most frequently attacks the lungs, causing pulmonary TB. This is the most common form of the disease. [Source: American Lung Association, CDC, Merck Manual, Johns Hopkins Medicine, WHO]

Other Organs: While less common, TB can also affect the liver, spleen, and other organs throughout the body. This is often described as miliary TB when it affects multiple organs simultaneously. [Source: National Institute for Communicable Diseases, The Conversation, Merck Manual]
Understanding Extrapulmonary Tuberculosis
Extrapulmonary TB refers to TB infection outside the lungs. It's important to note that having the TB bacteria doesn't automatically mean active disease. Symptoms vary depending on the organ affected. [Source: Reference material on the difference between infection and active disease]
While the lungs are the primary target, the bacteria can spread through the bloodstream to other organs, leading to various symptoms and complications. Early diagnosis and treatment are crucial for preventing severe complications and effectively managing the infection. [Source: Multiple sources mentioning early diagnosis and treatment]
