Understanding Tuberculosis Symptoms, Causes, and Diagnosis

Tuberculosis Symptoms, Causes, and Diagnosis | A Comprehensive Guide

What is Tuberculosis?

Tuberculosis, also known as TB, is a serious and contagious bacterial infection that primarily affects the lungs. It can also affect other parts of the body, such as the brain, spine, and kidneys. TB is spread through the air when an infected person coughs, sneezes, or talks.

What are the Symptoms of Tuberculosis?

The symptoms of TB can vary depending on the severity of the infection and the part of the body that is affected. Some common symptoms include:

  • Persistent cough that lasts for more than three weeks
  • Chest pain or discomfort
  • Fatigue or weakness
  • Fever and night sweats
  • Loss of appetite and weight loss
  • Coughing up blood or phlegm

What are the Causes of Tuberculosis?

TB is caused by the bacterium Mycobacterium tuberculosis. It spreads through the air when an infected person coughs, sneezes, or talks. People with weakened immune systems, such as those with HIV or diabetes, are more susceptible to TB. It can also spread more easily in crowded living conditions and in areas with poor ventilation.

How is Tuberculosis Diagnosed?

Diagnosing TB involves a series of tests, including:

  • Tuberculin skin test: A small amount of fluid is injected under the skin, and the area is checked for a reaction after a few days.
  • Blood tests: These tests can detect antibodies to the TB bacteria. e.g. TB Gold test, TB by PCR test
  • Chest X-ray: This can show signs of TB infection in the lungs.
  • Sputum test: A sample of phlegm is analysed for the presence of TB bacteria.

How is Tuberculosis Treated?

TB is treated with a combination of antibiotics for at least six months. It is important to take the full course of antibiotics, even if symptoms improve, to prevent the development of drug-resistant TB. In addition to antibiotics, people with TB may need to take other medications to manage symptoms and side effects.
