Tuberculosis or Pneumonia? Spot the Differences Before It’s Too Late

Both tuberculosis (TB) and pneumonia affect the lungs—and both can make you seriously ill. But knowing the difference between them could be life-saving. While symptoms often overlap, the underlying causes, treatments, and long-term risks are very different.

At O2XY Clinics, we specialize in identifying and managing complex lung infections. Let’s explore how you can tell whether it’s TB or pneumonia—and why you should never ignore either.

What is Pneumonia?

Pneumonia is an acute lung infection that inflames the air sacs in one or both lungs. These air sacs may fill with fluid or pus, causing cough, fever, and difficulty breathing. Pneumonia can be caused by bacteria, viruses, or fungi.

Common Symptoms:

• High fever with chills
• Chest pain during breathing or coughing
• Fatigue
• Shortness of breath
• Wet cough with yellow or green sputum

What is Tuberculosis (TB)?

Tuberculosis is a chronic bacterial infection caused by Mycobacterium tuberculosis. It primarily affects the lungs but can spread to other parts of the body. Unlike pneumonia, TB develops slowly and can become life-threatening if untreated.

Common Symptoms:

• Persistent cough (3+ weeks)
• Blood-tinged sputum
• Night sweats
• Weight loss and appetite loss
• Low-grade fever over a long period

Key Differences at a Glance

When to See a Pulmonologist

If you experience a persistent cough, chest pain, or unexplained weight loss, it’s crucial to get evaluated. Early detection of TB or pneumonia can prevent complications like pleural effusion, lung collapse, or chronic lung damage.
