What Is Tuberculosis?

Tuberculosis is a general term for the infection of our body by the bacillus called Mycobacterium tuberculosis. Tuberculosis may affect not only the lungs, but also the brain, kidneys, spine and other body organs. Still—the most common form of TB is pulmonary tuberculosis.

When we acquire this certain bacteria, it dwells in our lung lobes through capsules (Ghon’s focus) and stay there as it multiplies. When the bacteria has multiplied and infested our lungs, these capsules may open up and lead to signs and symptoms of the disease.

What Are the Tuberculosis Causes?

Tuberculosis causes may vary and most commonly, it can be transferred from one person to another by droplet transmission.

Sneezing and Coughing Without Covers

This is the most common among all forms of tuberculosis causes. People around us cough, sneeze and excrete respiratory secretions. When these fluids spread and gets in contact with another person, these bacteria can be lodged into our respiratory tract and dwell inside our lungs.


Proper hygiene is a common reason why people get infected with tuberculosis. Making use of clean and personal things like towels, handkerchief, etc all the time; as well as doing hand washing every now and then, are good ways of preventing tuberculosis causes.

Low Immune System

Our immune system is responsible in protecting us from the infectious properties of microorganisms that we encounter on a day to day basis. When our immune system is lowered, we are most prone to catching diseases and getting full blown infections like tuberculosis.

Taking vitamins and eating nutritious foods will help us boost our immune system and prevent the incidences of developing infectious diseases.

Tobacco Smoking

Cigarette smoking is all bad and will not bring any benefits at all. It is also one of the predisposing tuberculosis causes. With smoking, the linings of our respiratory tract as well as our lungs become defective leading to a higher probability of getting respiratory infections.

Cutting down, if not completely quitting tobacco and cigarette smoking is an effective way of countering tuberculosis causes.

Tuberculosis can be fatal once a person develops a full blown type of this disease. Practice a healthy and hygienic lifestyle and steer clear from the deadly course of this disease.
