Which part of your body is affected by tuberculosis?

Tuberculosis (TB) is a disease caused by germs that are spread from person to person through the air. TB usually affects the lungs, but it can also affect other parts of the body, such as the brain, the kidneys, or the spine. A person with TB can die if they do not get treatment.

Which part of the body does tuberculosis affect first?

The bacteria usually attack the lungs, but TB bacteria can attack any part of the body such as the kidney, spine, and brain. Not everyone infected with TB bacteria becomes sick. As a result, two TB-related conditions exist: latent TB infection (LTBI) and TB disease. If not treated properly, TB disease can be fatal.

How is the body affected by tuberculosis?

When a person gets active TB disease, it means TB bacteria are multiplying and attacking the lung(s) or other parts of the body, such as the lymph nodes, bones, kidney, brain, spine and even the skin. From the lungs, TB bacteria move through the blood or lymphatic system to different parts of the body.

Which part of body is not affected by TB?

This hematogenous transmission can also spread infection to more distant sites, such as peripheral lymph nodes, the kidneys, the brain, and the bones. All parts of the body can be affected by the disease, though for unknown reasons it rarely affects the heart, skeletal muscles, pancreas, or thyroid.

What are the 3 types of tuberculosis?

Tuberculosis is a bacterial infection that usually infects the lungs. It may also affect the kidneys, spine, and brain. Being infected with the TB bacterium is not the same as having active tuberculosis disease. There are 3 stages of TB—exposure, latent, and active disease.

How does TB affect the lungs?

tb infection because they cause airway inflammation driving airway obstruction, making airways smaller which increases air velocity and displaces air to unobstructed areas. Thus, airway inflammation can result in prolonging M. tb infection and deposition/movement of M. tb to healthy areas of the lung [3].

Where did tuberculosis come from?

tuberculosis was originated in East Africa about 3 million years ago. A growing pool of evidence suggests that the current strains of M. tuberculosis is originated from a common ancestor around 20,000 – 15,000 years ago.

The BCG vaccine is made from a weakened strain of TB bacteria. Because the bacteria in the vaccine is weak, it triggers the immune system to protect against the infection but does not give you TB. It provides consistent protection against the most severe forms of TB, such as TB meningitis in children.

How long does TB last?

Most people with TB disease will need to take TB medicine for at least 6 months to be cured.

Can TB be cured?

How does TB affect kidneys?

tuberculosis was isolated from the urine. Ultimately, a tuberculous kidney may become calcified and nonfunctioning. Not surprising, if the gross anatomic distortion is advanced and bilateral, the GFR will fall and, in some patients, there is progression to end-stage renal failure.

Why do TB patients cough?

People with pulmonary TB cough a lot, because the destruction of tissue in the lungs and airways leads to inflammation. The body reacts to inflammation by trying to eliminate the particle that caused it – if this happens in the airway, the easiest way to eliminate the cause is to cough it up.

Is a TB cough wet or dry?

Bacillus Calmette-Guerin (BCG) vaccination is compulsory in 64 countries and recommended in others [1]. Recently, the World Health Organization expanded programs of immunization recommended BCG at 3 months [2], while in many areas there is vaccination at birth [3], at school entry and in adolescence [4].

When do TB symptoms start?

TB disease usually develops slowly, and it may take several weeks before you notice you're unwell. Your symptoms might not begin until months or even years after you were initially infected. Sometimes the infection does not cause any symptoms. This is known as latent TB.
