Introduction 

Tuberculosis, or TB, is a serious infection that mainly targets the lungs. When TB bacteria enter the lungs, they can cause lasting damage. Many people wonder how tuberculosis affects your lungs, what symptoms to watch for, and how TB spreads in the lungs. Early signs, such as cough or chest pain, may seem mild. However, untreated TB can lead to severe lung problems. Understanding lung tuberculosis symptoms and TB lung damage helps you seek care quickly. 

What Is Tuberculosis? 

Tuberculosis is an infection caused by bacteria called Mycobacterium tuberculosis. Most often, it attacks the lungs, but it can also affect other parts of the body. TB spreads through the air when a person with active TB coughs or sneezes. Because of this, it is important to know how TB spreads in the lungs and how to protect yourself. 

  TB is a leading cause of death from infection worldwide (WHO). 

  It is more common in crowded places or areas with poor ventilation. 

  People with weak immune systems are at higher risk. 

How Tuberculosis Infects the Lungs 

Once TB bacteria enter your body, they usually settle in the lungs. There, they start to multiply. Over time, they form small lumps called tubercles. These lumps can damage lung tissue. As a result, breathing becomes harder. In some cases, the infection spreads to other parts of the lungs or even outside the lungs. 

  TB bacteria can stay inactive in the lungs for years. 

  When the immune system weakens, the bacteria become active. 

  Active TB causes lung tissue to break down, leading to cavities or holes. 

Symptoms of Lung Tuberculosis 

At first, lung tuberculosis symptoms may be mild. But as the infection grows, symptoms become more noticeable. Early detection helps prevent TB lung damage. 

  Persistent cough lasting more than three weeks 

  Coughing up blood or mucus 

  Chest pain, especially when breathing or coughing 

  Fever and night sweats 

  Unexplained weight loss 

  Feeling tired or weak 

Sometimes, people do not have any symptoms. This is called latent TB. However, latent TB can become active later. 

Diagnosis of Tuberculosis in the Lungs 

Doctors use several tests to find out if you have lung TB. Early diagnosis is key to stopping the spread and preventing lung damage. 

  Chest X-ray: Shows changes or damage in the lungs. 

  Sputum test: Checks for TB bacteria in mucus from your lungs. 

  Skin or blood tests: Reveal if you have been exposed to TB. 

In some cases, doctors may order a CT scan or other tests for a clearer picture. 

Treatment Options for Lung Tuberculosis 

Treating lung tuberculosis requires a combination of antibiotics. Treatment usually lasts six months or longer. It is important to take all medicines as prescribed, even if you feel better. This helps prevent TB from coming back or becoming resistant to drugs. 

  Doctors often use four main antibiotics at first. 

  After two months, you may need fewer medicines. 

  Missing doses can make TB harder to treat. 

With proper treatment, most people recover fully from lung TB. 

Preventing Tuberculosis Infection 

There are steps you can take to lower your risk of getting TB. Prevention is especially important in areas where TB is common. 

  Cover your mouth when coughing or sneezing. 

  Wash your hands often. 

  Stay in well-ventilated areas. 

  Get tested if you have been around someone with TB. 

  Take all medicine if you are diagnosed with latent TB. 

  Vaccination (BCG) may help protect young children in some countries. 

Living with Lung Tuberculosis: Lifestyle Tips 

Managing life with lung TB can be challenging. However, healthy habits can support your recovery and protect others. 

  Take all medicines exactly as your doctor says. 

  Eat a balanced diet to help your body heal. 

  Get enough rest each day. 

  Avoid smoking or being around smoke. 

  Follow up with your doctor for regular check-ups. 

  Let friends and family know about your treatment plan.
