What is the first sign of tuberculosis in lungs?
Tuberculosis (TB) is a serious infectious disease that primarily affects the lungs. It is caused by the bacterium Mycobacterium tuberculosis. While TB is preventable and treatable, it can be fatal if left untreated.
Early detection is crucial for successful treatment and preventing the spread of the disease. However, the first sign of tuberculosis in lungs can be subtle and easily mistaken for other illnesses.
Common early symptoms of TB in the lungs include:
- A persistent cough lasting three weeks or more. This is often the first and most noticeable symptom.
- Coughing up blood or phlegm. This can be a sign that the infection is becoming more serious.
- Chest pain. This pain can be sharp or dull and may worsen when you breathe deeply or cough.
- Fatigue. Feeling tired or weak even after getting enough sleep is a common symptom of TB.
- Weight loss. This is often accompanied by loss of appetite.
- Fever. A low-grade fever, especially in the evenings, is another possible symptom.
- Night sweats. Waking up drenched in sweat during the night can be a sign of TB.
- Shortness of breath. Difficulty breathing or feeling like you can't get enough air can be a sign that the infection is affecting your lungs.
It's important to note:
- Not everyone with TB will experience all of these symptoms. Some people may only have a few or even just one symptom.
- These symptoms can also be caused by other illnesses. If you experience any of these symptoms, it's important to see a doctor to get diagnosed and treated.
Seeking medical attention:
If you experience any of the above symptoms, it's crucial to consult a doctor immediately. Early diagnosis and treatment are essential to prevent complications and spread of the disease.
A doctor can perform a variety of tests to diagnose TB, including:
- Tuberculin skin test (TST)
- Interferon-gamma release assay (IGRA)
- Chest x-ray
- Sputum culture
Prevention:
The best way to prevent TB is to avoid contact with people who have the disease. Vaccination against TB is also available and is recommended for individuals at high risk.
Remember, TB is a preventable and treatable disease. Early diagnosis and treatment are crucial for preventing complications and spreading the infection.
