Tuberculosis: Deadly infectious but curable disease


Tuberculosis or TB is an infectious disease that primarily affects the lungs. The bacteria usually spreads to people when an infected person sneezes or coughs which is why it is essential to timely diagnose TB and seek immediate medical attention. Let us take a look at how the disease can be treated in time. TB infection happens owing to the bacteria Mycobacterium tuberculosis. It will take a toll on one’s lungs but can also impact other parts of one’s body along with the lymph glands, brain, kidneys, bowels, or bones.

Common symptoms

Some common symptoms are fatigue, loss of appetite, constant cough, fever, night-time sweating, cough with thick mucous and even coughing up blood. The symptoms may appear mild for a few months and then can drastically increase. Thus, a delay in treatment can increase your risk of spreading the infection. Hence, opt for tests immediately after you notice the symptoms.


The diagnosis of TB can be done by taking a sample of the mucous. A patient may be asked to go for sputum sample testing. Also, individuals may also be asked to undergo an X-ray, blood test, or even sputum smear microscopy to check prevalence of TB.

Disease curable

TB is curable if treated with the drug combination for a minimum of six months.
If a person fails to seek appropriate treatment or even do not follow the instructions given by the doctor, then the TB bacteria may get stronger and symptoms may reappear and this can be known as drug-resistant TB. This drug-resistant TB can be serious. Multi-drug resistant TB is a form caused by bacteria that does not respond to two of the most powerful drugs. Treatment options for MDR-TB are limited and expensive. In case a person has TB infection and symptoms are not visible, that is latent TB. Then, the person may be at the risk of suffering from TB in the near future. Thus, one is advised to take treatment for only a short period to stop the infection and have to speak to a nutritionist about the foods to include and exclude in the diet.
