Tuberculosis in India: Symptoms, Causes, and Treatment Options

Tuberculosis (TB), commonly known as TB, is a serious disease caused by bacteria that often affects the lungs. This blog will cover the definition, causes, treatment (especially in a country like India), recent efforts to fight TB globally, the link between TB and diabetes, and the importance of accessible healthcare for everyone. 

Key Facts

  • Serious illness: Sadly, 1.3 million people died from TB in 2022, which is the second most common cause of death from an infectious disease worldwide (after COVID-19).
  • Widespread: Over 10 million people got sick with TB in 2022, affecting people of all ages and genders around the world.
  • Good news: TB is curable and preventable!
  • Challenge: A type of TB called MDR-TB is difficult to treat, and many people who have it haven’t received proper medical care.
  • Progress: Despite the challenges, global efforts have saved millions of lives from TB since the year 2000.

What is Tuberculosis?

Tuberculosis is an infectious disease caused by the bacterium Mycobacterium tuberculosis. This bacterium typically targets the lungs, leading to symptoms like persistent cough, chest pain, weight loss, and fatigue.

TB is spread through the air when an infected person coughs or sneezes, releasing tiny droplets containing the bacteria. Individuals with weakened immune systems are particularly vulnerable to TB, making early detection and treatment vital.

Causes of Tuberculosis

When an infected person coughs or sneezes, Mycobacterium tuberculosis is released into the air. If inhaled by someone nearby, the bacteria can infect their lungs, leading to the development of TB.

Factors contributing to the spread of TB include crowded living conditions, poor ventilation, and compromised immune systems.

In India, a combination of factors such as high population density, limited access to healthcare in certain regions, and socioeconomic challenges has made TB a persistent public health concern.

Efforts to control the disease include raising awareness, improving living conditions, and ensuring widespread access to healthcare services.

Although TB is contagious, it’s not easy to catch. You’re much more likely to get TB from someone you live with or work closely with than from a stranger. Most people with active TB who’ve had appropriate drug treatment for at least two weeks are no longer contagious.

symptoms of tuberculosis

  • Persistent cough (lasting 3 or more weeks)
  • Coughing up blood
  • Chest pain, or pain with breathing or coughing
  • Unintentional weight loss
  • Fatigue
  • Fever
  • Night sweats
  • Chills
  • Loss of appetite

Most people who have TB infection don’t have symptoms. When symptoms of TB occur, they usually include a feeling of sickness or weakness, weight loss, fever, and night sweats.

The symptoms of TB of the lungs may include coughing, chest pain, and coughing up blood. Symptoms of TB in other parts of the body depend on the area affected.

If not treated properly, TB disease can be fatal. But TB is curable and preventable. Treatment usually involves taking antibiotics for several months.

Tuberculosis Treatment in India

The good news is that TB is treatable, and effective medications are available. In India, the government has implemented a National Tuberculosis Control Program (NTCP) to ensure that TB treatment is accessible to all.

You can read The NATIONAL STRATEGIC PLAN FOR TUBERCULOSIS ELIMINATION 2017–2025. Let’s delve into the key aspects of TB treatment in the country.

1) Diagnosis

TB diagnosis often begins with a chest X-ray and a sputum test. The X-ray helps identify any abnormalities in the lungs, while the sputum test detects the presence of the TB bacterium.

2) Directly Observed Treatment Short-course (DOTS)

The DOTS program is a cornerstone of TB treatment in India. It involves a healthcare worker directly observing patients as they take their prescribed medications. This ensures adherence to the treatment regimen, which is essential for successful recovery.

3) Spinal Tuberculosis Treatment in India

Antitubercular medications, physical therapy, and surgery are used in the treatment of spinal tuberculosis to prevent damage and paralysis in severe cases. The course of treatment typically lasts six to nine months, and patients who receive an early diagnosis and fast treatment have a high success rate that improves their quality of life and functional status.

4) Medications

The standard TB treatment involves a combination of antibiotics, usually taken for six months. Common medications include isoniazid, rifampicin, ethambutol, and pyrazinamide. Patients must complete the entire course of medications, even if symptoms improve before completion.

5) Drug-resistant TB

In some cases, TB bacteria may develop resistance to standard medications, leading to drug-resistant TB. In such instances, a more prolonged and complex treatment regimen, often involving second-line drugs, is required. The management of drug-resistant TB poses additional challenges but is a critical component of TB control efforts.

6) Community Involvement

TB treatment in India is not only about medications. It involves community awareness, education, and engagement. Community health workers play a crucial role in identifying and supporting individuals with TB, ensuring they adhere to their treatment plans.

The Role of Pulse Oximeters in Tuberculosis Patients

The Role of Pulse Oximeters in Tuberculosis Patients Pulse oximeters play a crucial role in monitoring the health of tuberculosis (TB) patients. TB often affects the lungs, causing respiratory issues that can lead to reduced oxygen levels in the blood.

A pulse oximeter measures oxygen saturation levels in the blood, offering a non-invasive way to assess how well the lungs are functioning.

For TB patients, regular monitoring of oxygen saturation levels using a pulse oximeter helps healthcare providers detect early signs of respiratory distress or hypoxemia (low oxygen levels).

It allows timely intervention, ensuring appropriate medical management to prevent complications related to low oxygen in the bloodstream.

As TB treatment progresses, the pulse oximeter becomes a valuable tool in tracking the patient’s respiratory health and adjusting treatment plans accordingly.

Challenges and Future Directions

While significant progress has been made in TB treatment in India, challenges persist. The stigma associated with TB, especially drug-resistant strains, remains a barrier to early detection and treatment. Additionally, the need for ongoing efforts to improve healthcare infrastructure and accessibility is evident.

Looking ahead, research and innovation are essential in developing more effective and shorter-duration treatments. Increased public awareness campaigns, community involvement, and continued governmental support will contribute to the overall success of TB control initiatives in India.

test for tuberculosis in India

As an expert in tuberculosis testing, it’s crucial to raise awareness among individuals about the available diagnostic tests for tuberculosis. Understanding these tests can empower patients to seek timely screening and treatment.

Firstly, the tuberculin skin test (TST) and interferon-gamma release assays (IGRAs) are common methods used to detect TB infection. The TST involves a small injection of tuberculin under the skin, with a subsequent evaluation for a reaction. Meanwhile, IGRAs analyze blood samples to detect immune responses to TB bacteria.

Additionally, sputum tests, chest X-rays, and molecular diagnostic techniques play pivotal roles in confirming TB infection and distinguishing between latent and active disease. These tests help healthcare providers tailor appropriate treatment plans.

I encourage everyone, especially those at risk or experiencing symptoms like persistent cough, fever, or weight loss, to discuss TB testing options with healthcare professionals. Early detection not only facilitates prompt treatment but also aids in preventing the spread of TB within communities.

Remember, understanding TB tests and proactively seeking screenings can significantly contribute to managing and controlling tuberculosis.

World Diabetes Day: WHO Advocates Equitable Access to Care for Diabetes and TB

In anticipation of World Diabetes Day on November 14, the World Health Organization (WHO) is emphasizing the critical importance of equitable access to essential care for individuals affected by diabetes and tuberculosis (TB).

This focus on equal access is not only vital for addressing diabetes but is also integral to the goal of ending TB, as outlined in WHO’s End TB Strategy and reinforced in the political declarations of the United Nations high-level meetings on the fight against TB in 2018 and 2023.

According to the 2023 WHO Global TB Report:

Diabetes stands out as a key determinant of TB, contributing to just under 400,000 TB episodes worldwide. Individuals with diabetes face an elevated risk of developing TB and are more prone to experiencing poor TB treatment outcomes, including mortality.

This underscores the urgent need to ensure comprehensive care accessibility for those affected by both diabetes and TB.

Let’s confirm our dedication to promoting healthcare systems that do not exclude anyone on World Diabetes Day. In addition to being a fundamental right, the demand for equal access is also a strategic necessity in our effort to defeat tuberculosis and create a healthier world.


Tuberculosis (TB) is a highly prevalent infectious disease in India. The symptoms of TB include coughing, chest pain, fatigue, and weight loss. The disease is spread through the air when an infected person coughs or sneezes. Poverty, poor living conditions, and lack of access to health care contribute to the high rates of TB in India.

Treatment options for TB include a combination of antibiotics over several months. However, the emergence of drug-resistant strains of TB poses a challenge for effective treatment. Proper diagnosis, early detection, and treatment adherence are crucial in controlling the spread of TB in India.
