On the Rise: Five Respiratory Illnesses You Should Know About

In recent years, there has been a significant increase in various types of respiratory illnesses around the globe. Today, we will dive into five of these illnesses that have shown an alarming rise and the need for increased vigilance and understanding. We’ll discuss the basics for each, as well as their causes, and treatment options.

1. Asthma

Asthma is a chronic disease involving the airways in the lungs. These airways become inflamed and the muscles around the airways tighten when something triggers symptoms. The symptoms include shortness of breath, wheezing, coughing, and chest tightness. Over the years, there has been a steady rise in the number of asthma cases worldwide, making it a significant global health concern.


Asthma can be caused by a variety of factors including genetics, early childhood development, and environmental factors. It’s essential to understand the triggers which can range from allergens like dust mites, pet dander, and pollen to irritants like smoke and chemical fumes. Additionally, certain respiratory infections during childhood, certain medications, physical activity, and even weather changes can induce asthma symptoms.


While there is no cure for asthma, the symptoms can be managed with proper intervention and medication. This includes long-term control medicines to help reduce the inflammation in the airways, and quick-relief medicines to ease symptoms during an asthma attack. Lifestyle modifications, such as avoiding triggers and regular exercise, can also help manage the symptoms.

2. Chronic Obstructive Pulmonary Disease (COPD)

COPD is a term used to describe progressive lung diseases including emphysema, chronic bronchitis, refractory asthma, and some forms of bronchiectasis. This disease is characterized by increasing breathlessness, making it difficult for the person to breathe. It’s a growing health problem and a leading cause of death worldwide.


COPD is caused primarily by smoking and exposure to secondhand smoke. However, other factors such as occupational exposure to dust and chemicals, indoor and outdoor air pollution, and certain genetic conditions can also lead to COPD. Long-term exposure to these irritants can damage the lungs and the airways, leading to COPD.


COPD has no cure yet. However, lifestyle changes and treatments can help you feel better, stay more active, and slow the progress of the disease. These include quitting smoking, avoiding exposure to lung irritants, and taking medications as prescribed by the doctor. Pulmonary rehabilitation, a program of exercise, disease management, and counselling, can also improve the quality of life.

3. Pneumonia

Pneumonia is an infection in one or both lungs that can be caused by bacteria, viruses, or fungi. It leads to inflammation in the air sacs in your lungs, which fill with fluid or pus, causing symptoms such as cough with phlegm or pus, fever, chills, and difficulty breathing.


While many germs can cause pneumonia, the most common are bacteria and viruses in the air we breathe. Your body usually prevents these germs from infecting your lungs, but sometimes these germs can overpower your immune system, even if your health is generally good.


Most cases of pneumonia can be treated at home with rest, antibiotics (for bacterial pneumonia) or antivirals (for viral pneumonia), and by drinking plenty of fluids. Severe cases may need to be treated in a hospital.

4. Tuberculosis (TB)

Tuberculosis is a serious infectious disease that primarily affects the lungs but can affect other parts of the body as well. It is caused by the bacterium Mycobacterium tuberculosis. Despite being a preventable and curable disease, tuberculosis remains a major global health problem.


The bacterium Mycobacterium tuberculosis causes tuberculosis. It spreads from person to person through microscopic droplets released into the air when the person with TB of the lungs or throat coughs, speaks, or sings.


With timely detection and proper drug treatment, TB can be cured in the majority of cases. The standard treatment for TB is a course of four antimicrobial drugs for six months.

5. Pulmonary fibrosis

Pulmonary fibrosis is a lung disease that occurs when lung tissue becomes damaged and scarred. This thickened, stiff tissue makes it more difficult for your lungs to work properly, causing shortness of breath, a persistent dry, hacking cough, fatigue, and weakness.


The cause of pulmonary fibrosis is often unknown. However, certain environmental factors and treatments can lead to pulmonary fibrosis. These include exposure to certain toxins and pollutants, including silica dust, asbestos fibers, hard metal dusts, coal dust, and radiation treatments.


While there’s currently no cure for pulmonary fibrosis, medications and therapies can sometimes help ease symptoms and improve quality of life. For some people, a lung transplant might be appropriate.


While these respiratory illnesses are on the rise, understanding the causes and treatment options can help in managing them effectively. Always consult with a healthcare provider for accurate information.
