1. Persistent Cough

One of the main signs of TB is a chronic cough. Phlegm or sputum may be produced, which might be bloody or discolored, and it may linger for several weeks. Although the cough may start off being light and sporadic, as the illness worsens, it gets more severe and persistent.

Due to the buildup of bacteria in the lungs, people with TB may experience coughing fits, especially in the morning or at night. Mycobacterium tuberculosis, which causes TB, is a contagious bacterial infection that mostly affects the lungs.


2. Fatigue and Weakness

Individuals with TB frequently experience persistent weariness and weakness. The infection strains the body's immune system, leaving you unmotivated and worn out. Other symptoms like appetite reduction, accidental weight loss, and decreased physical stamina may also occur along with fatigue.

It's critical to manage these symptoms as soon as possible in order to avoid subsequent issues and to advance general well-being. The most typical signs of tuberculosis are a bloody cough, exhaustion, weight loss, and night sweats.


3. Night Sweats

People with TB frequently experience night sweats. These episodes of excessive nighttime perspiration can be drenching, necessitating a change of bed linens. Fever is frequently present with night sweats, which can interfere with sleep cycles. It's critical to distinguish TB from other possible causes of night sweats and seek medical attention for a precise diagnosis.

When an infected individual coughs or sneezes, TB spreads via the air, making it extremely contagious.


4. Fever (Tuberculosis)

A typical TB symptom is a low-grade fever that lasts for a long time. The immune system of the body raises the body's core temperature in response to the infection, causing a fever that may linger for weeks. The fever may change during the day, and it frequently comes with additional symptoms including exhaustion and night sweats.

For a good diagnosis and course of therapy, fever in those suspected of having TB must be monitored and managed. Tuberculosis can have serious side effects and even be fatal if it is not treated.


5. Unintentional Weight Loss

One crucial indicator of TB is unexplained weight loss. People with active TB may gradually lose their appetite, which might result in accidental weight loss over time. Due to the infection's impact on the body's metabolism and vitamin shortages, malnutrition and weight loss are facilitated.

A medical practitioner should carefully assess unintentional weight loss and other symptoms to identify the underlying reason and select the best course of treatment. Effective management of tuberculosis and its prevention depends on early diagnosis and the right treatment.


6. Chest Pain and Shortness of Breath

TB can occasionally result in shortness of breath and chest pain. Inflammation and scarring in the lungs from the infection can result in discomfort and breathing difficulties. Sharp or dull chest discomfort can worsen with inhaling deeply or coughing.

As the lungs work to deliver enough oxygen, shortness of breath can happen during exercise or even while at rest. These signs call for urgent medical intervention.


For early detection and treatment of tuberculosis (TB), it is essential to understand the symptoms. Common symptoms of TB include a persistent cough, exhaustion, night sweats, fever, unexpected weight loss, chest pain, and shortness of breath. It is crucial to get a quick medical evaluation if you encounter these symptoms or suspect TB, and to follow the recommended treatment plan.
