Tuberculosis (TB) is a serious infection that mainly affects the lungs. Symptoms of tuberculosis can vary depending on the part of the body infected but may include coughing up blood, chest pain, and difficulty breathing. Tuberculosis is caused by a bacterium called Mycobacterium tuberculosis, which most often affects the lungs. It can also affect other parts of the body including the brain, kidneys, and spine.

Tuberculosis is diagnosed with a simple skin test or by testing a sample of mucus from your lungs. Treatment for tuberculosis usually involves taking antibiotics for 6 to 9 months. Some people may also need to receive treatment for lung damage caused by tuberculosis. With proper treatment, most people with tuberculosis. Symptoms of tuberculosis can vary depending on the severity of the infection, but usually include a persistent cough, chest pain, coughing up blood, fatigue, and weight loss. In some cases, people may also experience night sweats, chills, fever, and shortness of breath.

Tuberculosis is caused by a bacterium called Mycobacterium tuberculosis. The disease is spread through the air when an infected person coughs or sneezes. It can also be spread through contact with saliva or mucus from an infected person. The bacteria can also be spread through close contact with someone who has pulmonary tuberculosis (a lung infection).

Tuberculosis (TB) is a bacterial infection that primarily affects the lungs. Symptoms can vary, but may include coughing up blood, chest pain, shortness of breath, fever, and weight loss. It can also spread to other parts of the body, such as the brain, kidneys, and spine. TB is diagnosed with a physical exam and tests that examine your sputum (mucus from your lungs) for bacteria. Treatment typically involves antibiotics and rest. Prevention includes early detection and treatment of active TB cases, as well as vaccinations for certain high-risk groups

Symptoms of tuberculosis can vary depending on the stage of infection. In the early stages, TB may cause fever, night sweats, weight loss, and feelings of sickness (malaise). As the disease progresses, coughing and chest pain may develop. If the infection spreads to other parts of the body, symptoms can include joint pain, fatigue, and swollen lymph nodes. There is no one definitive test for diagnosing tuberculosis. Most often a doctor will order a skin test or a chest X-ray. If tuberculosis is suspected, treatment should begin immediately even if a diagnosis has not been confirmed. Treatment typically involves a combination of antibiotics taken for several months. With proper treatment, most people with tuberculosis are cured. Symptoms of tuberculosis depend on where in the body the infection is. In most cases, tuberculosis causes a persistent cough that lasts for more than 3 weeks, along with chest pain and coughing up blood. Other symptoms can include weight loss, night sweats, fever, and fatigue.

Treatment for tuberculosis usually involves taking several drugs for 6 to 9 months.

Tuberculosis (TB) is a bacterial infection that mainly affects the lungs. However, TB can also affect other parts of the body, such as the brain, spine, and kidneys. Symptoms of tuberculosis vary depending on where the infection is located in the body.

Common symptoms of tuberculosis include:

-Coughing up blood or sputum (phlegm from deep inside the lungs)

-Chest pain

-Fatigue

-Weight loss

-Loss of appetite

-Night sweats

-Fever

-Shortness of breath

Tuberculosis symptoms may include a persistent cough, chest pain, coughing up blood, shortness of breath, rapid breathing, sweating at night, weight loss, and fatigue. TB is caused by the bacteria Mycobacterium tuberculosis. It can be spread through the air when a person with TB coughs or sneezes. The bacterium can also be spread through contact with urine, saliva, blood, or other body fluids from a person with TB.

TB is diagnosed with a chest X-ray and by testing samples of sputum (phlegm) for the presence of the bacteria. Treatment for TB includes taking antibiotics for 6 to 9 months. Surgery may also be needed to remove infected tissue.

Asthma

Asthma Symptoms in Adults: Early Signs, Triggers, and When to Seek Care

Asthma is often perceived as a childhood condition, but a significant number of cases develop or persist into adulthood. In India, adult asthma is increasingly recognised due to rising air pollution, occupational exposure and lifestyle-related risk factors. Unfortunately, asthma symptoms in adults are frequently misdiagnosed as recurrent infections, allergies or age-related breathlessness, leading to delayed treatment.

Understanding adult asthma symptoms is critical for early diagnosis, effective control and prevention of severe attacks.

 

What Is Asthma?

Asthma is a chronic inflammatory disease of the airways. In asthma, the airways become:

  • inflamed
     

  • narrow
     

  • overly sensitive to triggers
     

This leads to difficulty in breathing, especially during exposure to specific stimuli.

 

Why Adult Asthma Is Often Missed

Adult asthma symptoms may:

  • appear gradually
     

  • vary in severity
     

  • mimic common respiratory conditions
     

According to Indian Council of Medical Research and WHO data, many adults remain undiagnosed for years, increasing the risk of complications.

 

Common Asthma Symptoms in Adults

Wheezing

A high-pitched whistling sound while breathing, especially during exhalation, is a classic asthma sign.

 

Shortness of Breath

Adults with asthma often feel:

  • breathless during routine activities
     

  • difficulty taking deep breaths
     

This may worsen at night or early morning.

 

Chest Tightness

Many describe a sensation of pressure or tightness in the chest, which can be mistaken for heart-related issues.

 

Chronic Cough

A persistent cough, especially:

  • at night
     

  • early morning
     

  • after exercise
     

is a common but overlooked asthma symptom.

 

Symptoms That Worsen With Triggers

Asthma symptoms often intensify after exposure to specific triggers.

Air Pollution and Smoke

Urban pollution, vehicle emissions and indoor smoke significantly worsen asthma symptoms in adults.

 

Allergens

Dust mites, pollen, mould and pet dander are common triggers.

 

Respiratory Infections

Viral infections can trigger asthma flare-ups or reveal undiagnosed asthma.

 

Physical Activity

Exercise-induced asthma causes breathlessness and wheezing during or after physical exertion.

 

Weather Changes

Cold air, humidity and sudden temperature changes can aggravate symptoms.

 

Adult-Onset Asthma

Adult-onset asthma differs from childhood asthma.

Characteristics include:

  • onset after age 20–30
     

  • less association with childhood allergies
     

  • more persistent symptoms
     

  • higher likelihood of severe disease
     

Occupational exposure and hormonal changes contribute to adult-onset asthma.

 

Risk Factors for Asthma in Adults

Several factors increase asthma risk:

  • long-term exposure to pollution
     

  • smoking or passive smoking
     

  • occupational chemicals or dust
     

  • obesity
     

  • family history of asthma
     

  • chronic sinusitis or allergies
     

Women may experience asthma onset or worsening during hormonal changes.

 

When Asthma Symptoms Become Serious

Seek immediate medical attention if experiencing:

  • severe breathlessness
     

  • difficulty speaking in full sentences
     

  • bluish lips or fingertips
     

  • rapid worsening of symptoms
     

  • poor response to usual inhalers
     

These signs indicate a potentially life-threatening asthma attack.

 

How Adult Asthma Is Diagnosed

Diagnosis includes:

  • detailed symptom history
     

  • physical examination
     

  • lung function tests (spirometry)
     

  • response to bronchodilators
     

Early diagnosis improves long-term outcomes.

 

Impact of Untreated Asthma

Untreated asthma can lead to:

  • frequent attacks
     

  • reduced lung function
     

  • sleep disturbances
     

  • missed workdays
     

  • reduced quality of life
     

According to Lancet respiratory studies, uncontrolled asthma increases hospitalisation risk.

 

Managing Asthma Symptoms in Adults

Effective asthma management focuses on:

  • identifying and avoiding triggers
     

  • using prescribed inhalers correctly
     

  • monitoring symptoms regularly
     

  • maintaining follow-up care
     

Asthma action plans help patients recognise worsening symptoms early.

 

Role of Preventive Healthcare

Preventive healthcare helps:

  • detect asthma early
     

  • assess lung function
     

  • guide lifestyle modifications
     

Regular health checkups are especially important for individuals with respiratory symptoms or occupational exposure.

 

Lifestyle Measures That Support Asthma Control

Helpful practices include:

  • avoiding smoking
     

  • improving indoor air quality
     

  • wearing masks in polluted environments
     

  • maintaining healthy weight
     

  • regular, moderate exercise
     

Lifestyle support complements medical treatment.

 

Mental Health and Asthma

Stress and anxiety can worsen asthma symptoms.

Stress management:

  • reduces symptom frequency
     

  • improves medication response
     

Holistic care improves asthma outcomes.

 

Importance of Medication Adherence

Asthma medications work best when:

  • taken regularly as prescribed
     

  • inhaler technique is correct
     

Skipping treatment increases flare-up risk.

 

Long-Term Outlook for Adults With Asthma

With proper management:

  • symptoms are well controlled
     

  • severe attacks are preventable
     

  • normal activity levels are achievable
     

Most adults with asthma lead active, productive lives.

 

Conclusion

Asthma symptoms in adults are often subtle, variable and easily mistaken for common respiratory problems. Wheezing, breathlessness, chest tightness and chronic cough should not be ignored, especially when triggered by pollution, exercise or weather changes. Early diagnosis, trigger control and consistent treatment are essential to prevent severe attacks and preserve lung health. Recognising adult asthma early empowers individuals to manage symptoms effectively and maintain a good quality of life.
