Tuberculosis, commonly known as TB is an infectious disease that usually affects the lungs and is the second biggest killer, globally. It is a serious disease which generally affects the lungs, but later, it can spread to the other parts of the body as well. Anyone can get inflicted with this disease, but TB usually affects people who have a weak immune system. Also, it affects mostly young adults and people living in developing countries. Want to know all About  Tuberculosis Symptoms, its causes and Treatment-Read on!

It is scary to know that Tuberculosis is one of the leading causes of deaths globally. As per WHO Report of 2017, TB is still among the top 10 causes of death with a death toll of around 1.4 million worldwide.

During 18th and 19th century, TB began to increase in North America and Europe. In 1882, a German microbiologist Robert Koch discovered the microbial causes of TB.

After that, many vaccines and drugs were developed by the Doctors that made the medical professionals believe that the disease could be defeated. The belief was so strong that the United Nations, at one point predicted that TB would be eradicated worldwide by 2025.

However, unfortunately, the disease kept haunting the people and began to rise worldwide at such a fast rate that in 1993, the WHO (World Health Organization) declared that TB was a global emergency. Thankfully, after developing many strong control programs and intervention methods, the disease began to decrease after 1993. But, it still remains a concern as it is dangerous and contagious. With proper treatment, the disease can be cured.

An Overview of Tuberculosis

Tuberculosis is a disease which is infectious and affects the lungs. A TB infection does not always mean that the infected person will get sick. Sometimes, the immune system might prevent an infected person from becoming sick. And that is why the Doctors differentiate between two types of TB which are:

Latent TB

As the name says it all, ‘Latent’ means ‘Hidden’. In this kind of TB, the person has the germs in the body, but the body’s immune system stops them from spreading to other body parts. It means that the person does not experience any Tuberculosis Symptoms and the infection cannot be transmitted to others. But, the infection is present in the body which can become active any day.

Active TB

As the name suggests, in the active TB the bacteria causes symptoms which are experienced by the infected person, and it can be contagious. In this TB, the germs get multiplied and make people sick.

It is estimated that about one-third of the world’s population suffers from latent TB. But, there is only a 10% chance that TB will become active. Unfortunately, this risk is much higher in people who have a weak immune system, like people having HIV or people who smoke.

TB is a global disease and can affect all age groups. However, most young adults and people living in developing countries get affected by this disease.

Tuberculosis Symptoms

People with latent TB do not experience any Tuberculosis symptoms. People can get a skin or a blood test is done to find out if they are infected. But, people with an active TB usually experience several Tuberculosis symptoms such as:

-A Cough that lasts more than 3 weeks
-Coughing, with blood or mucus
-Loss of Weight
-Night Sweats
-Loss of Appetite
-Feeling tired all the time
-Chills
-Chest Pain

As mentioned earlier, TB affects the lungs usually but can affect the other body parts also. When TB hits other body parts, the symptoms vary accordingly. If proper treatment is not taken at the right time, the disease can spread to other body parts through the bloodstream:

-This disease, if infects the bones can cause joint destruction and spinal pain.
-When it affects the brain can lead to meningitis
-If kidneys and liver are infected, it may cause their impairment.
-TB infecting the heart can impair the ability of the heart to pump blood properly, which might result in a fatal condition called Cardiac Tamponade.

Causes of Tuberculosis

TB is caused by a bacteria known as the Mycobacterium Tuberculosis which is spread from one person to another through the air. When an individual who has TB coughs, sneezes, spits, laughs or talks, microscopic droplets that contain the germs are released into the air. When another person breathes in these germs, they get infected.

Although TB is contagious, it is not that easy to catch. The germs grow slowly. People have to spend a lot of time around a person infected with the bacteria. And that is why, there are higher chances of getting TB from a person with whom you spend most of the time, like family members, friends or a colleague.  There are fewer chances of getting this disease from a complete stranger. Also, most people with active TB do not remain contagious after they take appropriate treatment for at least two weeks.

Who is at Risk?

TB can affect anyone at any age. But, several factors can increase your chances of getting the disease. These factors include:

1.Weakened Body’s Immune System

If a person has a strong immune system, there are high chances that the body will be able to fight TB bacteria. However, if a person has a weak immune system, then the body will not be able to resist the bacteria causing TB.

That is why one must eat healthily and do exercise daily to strengthen their immune system.

Also, there are certain health conditions than weaken the body’s immune system, such as:

-HIV/AIDS
-Kidney Diseases
-Diabetes
-Some Kinds of Cancers
-Chemotherapy
-Drugs that are used to cure Crohn’s disease, Rheumatoid Arthritis and psoriasis.
-Young age
-Malnutrition

2.Substance Abuse

People who are alcoholic and take drugs are more prone to getting this disease. It is because drugs and alcohol weaken the body’s immune system and makes people more vulnerable to TB.

3.Living in Certain Places

The risk of getting TB is much higher in the places which is overcrowded and has poor ventilation which is why people working or living in immigration centres, prisons or nursing homes are at an increased risk of getting the disease. Also, refugees who live in a crowded area and in unsanitary conditions are at high risk of TB infection.So one needs to take precaution and be vigilant about Tuberculosis Symptoms should they emerge.

Diagnosis and Treatment of Tuberculosis

The Doctor will do a physical examination whereby they use a stethoscope listen to the sounds of lungs carefully and also check for swelling in the lymph nodes and look out for other Tuberculosis Symptoms. The Doctors also take the complete medical history of the patients to assess the individual’s risk of exposure to TB. The commonly used diagnostic tool for TB is a skin test in which a small injection of PPD tuberculin, which is an extract of the TB bacterium, which is injected just below the skin of the inside forearm.

A medical professional then check the arm for swelling at the injection site within 48 to 72 hours. If there is a hard, raised bump; it means that the patient is likely to have a TB infection.

The sad part is that skin test is not 100% accurate and might give incorrect positive and negative readings.

Fortunately, there are some other tests too like Blood Test, Chest X-Rays and sputum tests which help in diagnosing Tuberculosis.TB Gold test is a simple blood test which is done to detect the presence of Mycobacterium, the bacterium which causes TB. This test is offered at various Pathology Labs at an average cost of Rs. 2500 in India.

TB can be cured if it is administered at the right time and proper medication is taken. Also,  it can be cured. The time and length of the treatment depend on many factors including patient’s age, overall health, type of TB i.e. Latent or Active TB and the location of the infection(i.e. the brain, kidneys, lungs).

People with active TB generally require multiple drugs to get cured, whereas those with a latent TB may need only one kind of TB antibiotics. The patients need to take antibiotics for a long time. Generally, TB antibiotics are to be taken for 6 months.

The most common medications used to cure TB include:

-Isoniazid
-Rifampin (Rifadin, Rimactane)
-Ethambutol (Myambutol)
-Pyrazinamide

For the patients having drug-resistant TB, a combination of antibiotics called fluoroquinolones and injectable medications, such as amikacin, kanamycin or capreomycin, are used for 20 to 30 months generally. Certain kinds of TB are developing resistance to these medications as well.

Some new drugs are being looked at as add-on therapy to the current drug-resistant combination treatment, including:

-Bedaquiline
-Linezolid

The medications prescribed for TB sometimes can have some side-effects. Although it is quite uncommon, but the side effects may happen, and sometimes they can be quite dangerous.
Some of the potential side effects of TB medications could be:

-Loss of appetite
-Jaundice
-Dark Urine
-Nausea
-Fever

If the patient experiences any side-effects, he or she must consult the Doctor immediately. Also, even if the Tuberculosis Symptoms have gone away, the patients must complete the full course of the treatment.

Sure, tuberculosis is a life-threatening disease. But, it can be prevented by adopting a healthy lifestyle. Also, one must go for a regular Health Check-Up to screen for diseases. If you experience any Tuberculosis Symptoms , do visit a Doctor and get a TB Gold test done.
