Understanding Medicine: Tuberculosis
TUBERCULOSIS
Tuberculosis (TB) or also known as mycobacterium
tuberculosis is a type of mycobacteria that commonly infects the lungs however
also can infects any other part of the body includes glands.nervous system and
bones. About 2 billion people around the world infected with mycobacterium
tuberculosis where 90-95% of them are unaware they were infected.
Tuberulosis can be divided into two types which are
latent TB infection and active TB infection. What makes them different ? Latent
TB is when someone infected by TB but their immune system are unable to kill
the bacteria but only can stop the bacteria from infecting other parts of body.
In latent TB, patient will not experience any symptoms but the bacteria itself
remain in the body. Meanwhile in some cases in debilitated patient, for example
they might suffer from AIDS,old patients or patient with any immune system
disorder, immune cells in the body are unable to kill the bacteria which will
cause the patient to have potential to infect other people around. In active TB
infection, the bacteria can spread to other part of patient’s body and patients
themselves will develop symptoms.
Common symptoms in patients with TB infection includes
a persistent cough, weight loss, loss of apetite,tiredness and fatigue,night
sweats as well as high temperature of body. These are symptoms when the
bacteria only infects the lungs which also known as Pulmonary TB. In some cases
where the bacteria begin to spread to other part of the body, this circumstance
is known as extrapulmonary TB. Common symptoms includes persistence headache,
persistence swollen glands, confusion and pain and loss of movement in an affected bone or joint.
Now, who are the vulnerable group that we should protect more ? They are
those who have close contact to TB patient, live in country with high cases of
TB infection, patients that suffer immune system disorder (e.g: AIDS,SLE etc),
children, senior citizens and those with poor health or poor diet due to lifestyle
problems such as drug misuse and alcohol misuse.
How do GP diagnose TB ? The diagnosis might be a little bit difficult
and patient may required to undergo a few tests. Your GP usually will ask you
to undergo X-ray scan of your chest to identify any changes of your chest
appearance from normal one. Sampe of phlegm will be taken to test the presence
of TB bacteria in laboratory. Patient that is suspected to suffer
extrapulmonary TB will be required to undergo CT scan, MRI scan or ultrasound
scan to the specific part of body. Your GP may need your urine or blood test or
you might undergo biopsy where a sampe of tissue from the infected part of the
body will be taken to be examined.
If patient are confrimly diagnosed with TB infection, they will be prescribed
an antibiotics that last for several months where hospital admission is not
necessary. If diagnosed with TB, we are advised to isolate ourself from other
people including family and friends, always put on your face mask, dispose any
tissue that you use carefully in sealed plastic bag and open windows for better
fresh air supply in your house. Finally we are advised to take BCG vaccine in
order to prevent TB infection.
