Tuberculosis (TB) is an infection caused by the bacteria Mycobacterium tuberculosis. The condition usually affects the lungs and spreads through the air when a patient coughs, sneezes or spits. Individuals with a weak immune system, infants and children under four years of age, diabetics, people with chronic renal failure, tobacco users, those living in poorly ventilated and closed spaces and HIV-positive patients are at a greater risk of developing an active TB infection.
There are three stages of tuberculosis:
- Primary infection: The bacteria enters the body as we breathe. In the early weeks, the bacilli travel to the regional lymph nodes and enter the bloodstream. The infection may then spread to other parts of the body like lungs, bones, kidneys and meninges of the brain. However, this is less likely in patients who have been vaccinated or have had a prior infection.
- Latent infection: This occurs after primary infection. In 95% of cases, a person's immune system suppresses TB bacteria (preventing it from multiplying). This leads to the disappearance of symptoms even though a small amount of M.tb is still present in the person's body.
- Active disease: This stage occurs when the latent disease reactivates or if the patient gets re-infected
A person infected with tuberculosis may not have any specific symptoms (latent TB) or may present with symptoms (active TB) such as persistent cough with sputum for more than two weeks, low-grade fever, chills, breathlessness, enlarged lymph nodes, fatigue, weight loss, loss of appetite, coughing up blood and night sweats.

Tuberculosis is diagnosed through sputum smear and sputum culture, chest X-ray, blood test, a tuberculin skin test or interferon-gamma release assay. Treatment comprises the intake of multiple antibiotics for at least six months.
Homeopathic treatment, on the other hand, boosts the immune system (so it can clear out the infection on its own) and helps in quicker recovery. Homeopathic remedies are prescribed on the basis of patient’s personality and physiology. Common remedies for TB include lycopodium clavatum, kalium carbonicum, phosphorus, pulsatilla, silicea, spongia tosta, stannum metallicum and tuberculinum bovinum. The dosage is prescribed on a case by case basis.
