Understanding Tuberculosis
Tuberculosis is a bacterial infection caused by Mycobacterium tuberculosis. While it primarily targets the lungs, it can also spread to other parts of the body, making it a condition that requires careful attention and timely care.
There are different forms of TB, each with its own impact on the body:
- Pulmonary TB affects the lungs and is the most common form.
- Extrapulmonary TB spreads beyond the lungs, impacting areas like the lymph nodes, spine, or brain.
- Latent TB exists in the body without causing symptoms.
- Active TB is symptomatic and can spread to others.
Recognising the type of TB plays a key role in determining the right course of treatment.
Symptoms Of Tuberculosis
TB often develops gradually, and its symptoms may initially seem mild. However, as the condition progresses, certain signs become more noticeable.
Common symptoms include:
- A persistent cough lasting more than two to three weeks
- Fever that doesn’t subside
- Night sweats
- Unexplained weight loss
- Blood in sputum
- Constant fatigue
When these symptoms linger, they shouldn’t be ignored. Early testing can make a significant difference in both treatment and recovery.
Common Causes Of Tuberculosis
Tuberculosis spreads through the air. When an infected person coughs or sneezes, tiny droplets carrying the bacteria can be inhaled by others nearby.
Certain factors increase the risk of infection:
- Close and prolonged contact with someone who has TB
- A weakened immune system
- Poor nutrition or malnutrition
- Existing conditions like diabetes
- Smoking habits
Simple precautions, along with timely diagnosis, can go a long way in reducing the spread of this infection.
