Bronchiolitis is a viral infection that causes the bronchioles or airways in the lungs to swell, making breathing difficult. This is a frequent lung infection in infants and young children. The infection causes swelling, inflammation, and mucus buildup in the lung’s small airways.

Bronchiolitis symptoms typically last 1 to 2 weeks but can possibly continue longer. Children may experience breathing difficulties. Bronchiolitis usually begins with symptoms similar to a regular cold. However, it progresses and becomes more severe, resulting in coughing and a high-pitched whistling sound known as wheezing when exhaling.

Small children can spread bronchiolitis through personal contact, saliva, and mucous. The easiest method to avoid infection is to avoid people who are unwell and to wash their hands frequently.

Most children with bronchiolitis improve with home care. A small number of children require hospitalization. read more

Asthma can cause swelling and constriction of the airways, as well as increased production of mucus, leading to symptoms such as shortness of breath, coughing, wheezing during exhalation, and difficulty breathing. While asthma may only be a minor inconvenience for some people, others may experience significant difficulties that disrupt their daily activities and could potentially result in a life-threatening asthma attack.

Although asthma cannot be cured, it is possible to manage its symptoms. It is important to work with your doctor to monitor your symptoms and make adjustments to your treatment as needed, as the signs and symptoms of asthma can change over time. read more

Chronic obstructive pulmonary disease (COPD) is a chronic inflammatory lung disease that leads to a blockage of airflow from the lungs. It commonly arises from two conditions: emphysema and chronic bronchitis. When diagnosed with COPD, it implies that the patient exhibits symptoms or has both of these damaging lung conditions. As COPD progresses, breathing can become increasingly challenging.

• Chronic bronchitis: This is an inflammation of the bronchial tubes’ lining, which transports air to and from the lungs’ air sacs (alveoli). When triggered, the tubes undergo swelling, leading to the accumulation of mucus (commonly known as “phlegm” or “snot”) along the inner lining. This build-up constricts the opening of the tubes, resulting in difficulty in both inhaling and exhaling air from the lungs. Daily coughing and mucus (sputum) production are its main symptoms.
• Emphysema: Emphysema is a condition where the alveoli at the end of the tiniest air channels (bronchioles) of the lungs are destroyed as a result of harmful exposure to cigarette smoke and other irritating chemicals and particulate matter.
  The air sacs are essential for transporting carbon dioxide out and oxygen into the circulation. Emphysema damage obliterates the air sac walls, making it challenging to take a full breath.

Heart disease, lung cancer, and a number of other diseases are more likely to occur in people with COPD.

COPD, while being a chronic and progressive disease, is manageable with appropriate treatment. Patients with COPD can achieve effective symptom control, experience an improved quality of life, and reduce the risk of developing other associated medical conditions through proper care. read more

Pneumonitis refers to the inflammation of lung tissue, a condition that encompasses a variety of causes beyond infections, such as pneumonia, which also leads to lung tissue inflammation but is specifically caused by infections. The term “pneumonitis” is more commonly applied to noninfectious sources of lung inflammation, often stemming from exposure to airborne irritants linked to one’s hobbies or workplace. Additionally, this condition can be triggered by certain medications and some forms of cancer treatment, leading to not only breathing difficulties but also a range of other physical symptoms.

The inflammation caused by pneumonitis comes in multiple types of inflammation. Among them are:

• Acute: The onset of inflammation is sudden, and it diminishes quickly.
• Subacute: The progression of inflammation is slow and steady.
• Chronic: Long-term and persistent inflammation develops from inflammation.

The following types of pneumonitis includes:

• Acute interstitial pneumonitis: Your symptoms worsen swiftly as acute interstitial pneumonitis occurs suddenly.
• Chemical pneumonitis: When someone breathes in chemicals found in products used at home or at work, such as chemicals used in imaging tests, chlorine gas, insecticides, gasoline, and smoke, they might develop chemical pneumonitis.
• Hypersensitivity pneumonitis: When you breathe in (inhale) allergens such as dust, mold, bacteria, or microscopic scales from animal skin, hair, or feathers (dander), you may develop hypersensitivity pneumonitis.
• Radiation pneumonitis: Radiation pneumonitis may develop following cancer treatment with radiation therapy.

The primary indicators of pneumonitis often involve difficulty breathing, often coupled with a persistent dry cough lacking mucus production. Receiving a diagnosis typically requires specialized testing. The primary objectives of treatment are to diminish inflammation and steer clear of irritants. read more

Pneumonia is a lung infection caused by bacteria, viruses, or fungi, leading to inflammation and potentially fluid or pus accumulation in the lungs. The severity and treatment vary depending on the causative pathogen and the type of pneumonia, which is categorized by how and where it was acquired: community-acquired, hospital-acquired, or ventilator-associated.

• Community-Acquired Pneumonia (CAP):
  • Bacterial causes: The most common is Streptococcus pneumoniae, leading to pneumococcal disease which can also cause other infections like sinusitis and meningitis. Mycoplasma pneumoniae often causes a milder form known as atypical pneumonia. Other bacteria include Haemophilus influenzae, Chlamydia pneumoniae, and Legionella pneumophila (causing Legionnaires’ disease).
  • Viral causes: Common cold viruses, influenza, COVID-19, and respiratory syncytial virus (RSV) can also lead to pneumonia.
  • Fungal causes: Less common, affecting mainly those with compromised immune systems, include Cryptococcus, Pneumocystis jirovecii, and Coccidioides.
  • Protozoa causes: Rare causes like Toxoplasma can lead to pneumonia.
• Hospital-Acquired Pneumonia (HAP): Occurs in patients already hospitalized for other conditions, often caused by antibiotic-resistant bacteria like methicillin-resistant Staphylococcus aureus (MRSA), making it more severe and harder to treat.
• Healthcare-Associated Pneumonia (HCAP): Develops in long-term care facilities or during extended outpatient stays, usually involving antibiotic-resistant bacteria.
• Ventilator-Associated Pneumonia (VAP): Occurs in patients using a ventilator, commonly in an ICU setting, where the causative agents can be similar to those of CAP, including drug-resistant strains.
• Aspiration Pneumonia: Results from inhaling food, liquids, or vomit into the lungs, leading to infection if not expelled.

Pneumonia’s impact varies from mild to life-threatening, posing the highest risk to infants, young children, people over 65, and those with weakened immune systems or preexisting health conditions. read more

Respiratory Syncytial Virus (RSV) is a common cause of lung and respiratory tract infections, affecting both children and adults. By the age of 2, the majority of children have been exposed to this virus. While RSV symptoms in healthy adults and older children are usually mild and similar to those of a common cold, self-care measures are typically enough to manage any discomfort.

However, RSV can pose serious risks for certain groups, including babies under 12 months old, especially premature infants, older adults, individuals with heart and lung conditions, or those with weakened immune systems. In these vulnerable populations, RSV infections can lead to severe illness and complications. read more

Pleurisy, or pleuritis, arises when the pleura—two thin, protective layers of tissue enveloping the lungs and lining the chest cavity—become inflamed, leading to sharp, stabbing pains in the chest known as pleuritic pain. This discomfort escalates with breathing, coughing, or sneezing, as these actions cause the inflamed pleural layers to rub against one another. Normally, these layers are lubricated by a small amount of fluid in the pleural space, allowing for smooth, frictionless movement during respiration. However, inflammation disrupts this smooth interaction, making each breath painfully reminiscent of coarse surfaces grating together.

Treatment for pleurisy is twofold, aiming to both alleviate the immediate discomfort caused by the condition and address its root cause to prevent ongoing irritation. This usually involves managing the pain through medication and tackling the underlying condition, such as an infection or other disease, that led to the pleural inflammation. By controlling the inflammation and ensuring the pleura can move smoothly once more, patients can find relief from the acute pains of pleurisy and return to normal breathing patterns.

Pleurisy may also develop along with other conditions, such as:

• Pleural effusion: This happens when fluid accumulates in the space between the layers of tissue, alleviating pleuritic pain by separating the layers and preventing rubbing.
• Atelectasis: Breathing difficulties and coughing may occur when significant fluid buildup in the pleural space exerts pressure, potentially leading to partial or complete collapse of the lung.
• Empyema:  The formation of pus known as empyema, accompanied by fever, may develop when excess fluid in the pleural space becomes infected. read more

Sharp chest pain when breathing, along with fever, tiredness, and shortness of breath, could be signs of pleural empyema. It usually occurs after an infection. If not treated in time, it may lead to respiratory failure and eventually death.

Dr. Chawakorn Leampribun, a cardiothoracic surgeon at Vejthani Hospital, explains that pus in the pleural cavity can occur when the body has an infection, especially respiratory infection such as severe flu or pneumonia, which usually happens when we breathe in and out, our lungs expand and contract efficiently. However, when there is pus in the pleural space, the lungs will rub against the pus and will be compressed by the pus, not allowing it to expand and contract as well as before. As a result, there will be sharp pain in the chest when breathing, trouble breathing, inability to breathe, fever, and coughing. The most severe symptom is respiratory failure and having to use a ventilator, as well as the risk of developing bloodstream infection, which can lead to organ failure. read more

Tuberculosis (TB) is an infectious disease primarily affecting the lungs, although it can also impact organs such as the spine, brain, or kidneys. It is caused by a type of bacteria that spreads through airborne droplets when an infected person coughs, sneezes, or sings. TB is more prevalent in crowded environments, and individuals with weakened immune systems, like those with HIV/AIDS, are at greater risk.

The infection progresses through three stages: primary infection, latent TB infection, and active TB disease. In its latent stage, the infection is dormant and the individual shows no symptoms, but the bacteria remain in the body. If it progresses to the active disease stage, the person becomes contagious and exhibits symptoms.

Treatment for TB involves a course of antibiotics, although some bacterial strains have developed resistance to conventional treatments, complicating recovery efforts. read more

Emphysema is a lung disease that harms the air sacs or alveoli in the lungs, causing them to lose their elasticity. This can lead to the formation of blockages or obstructions that trap air inside the lungs, resulting in difficulty breathing or shortness of breath. The primary cause of emphysema is smoking, which is responsible for the majority of cases.

Alveoli are small, thin–walled, fragile air sacs that form clusters at the end of the bronchial tubes or airways deep within the lungs. When a person inhale air, it travels through the bronchial tubes until it reaches the alveoli. Once inside, the alveoli stretch, draws in oxygen, and delivers it to the blood. With emphysema, the alveoli are weakened and ruptured. This reduces the surface area of the lungs and, as a result, the amount of oxygen in circulation. The old air becomes trapped, preventing fresh, oxygen–rich air from entering.

Chronic obstructive pulmonary disease (COPD) is made up of two conditions: emphysema and chronic bronchitis. The majority of people who have emphysema also have chronic bronchitis. The most common cause of COPD is smoking. Treatment for emphysema usually involves quitting smoking and taking medications. This can only slow emphysema down but cannot heal the existing damage to the lungs. read more

A pulmonary embolism refers to a situation in which a blood clot obstructs an artery within the lung, leading to a cessation of blood circulation. Typically, these blood clots originate in the deep veins of the leg and then migrate to the lung. In rarer cases, these clots might form in veins located in other parts of the body. When blood clots manifest in one or multiple deep veins, this is termed deep vein thrombosis (DVT).

Because these clots can impede the blood flow to the lungs, a pulmonary embolism has the potential to be life–threatening. Nevertheless, swift and appropriate treatment significantly reduces the likelihood of fatality. Taking preventive measures to avoid blood clot formation in the legs plays a pivotal role in safeguarding against the occurrence of a pulmonary embolism.  read more

Interstitial lung disease, also known as diffuse parenchymal lung disease (DPLD), encompasses a wide range of conditions, the majority of which lead to the gradual formation of scar tissue in the lungs. This scarring ultimately hampers one’s ability to breathe and impedes the intake of sufficient oxygen into the bloodstream.

Long–term exposure to harmful substances, such as asbestos, can be a catalyst for interstitial lung disease. Additionally, certain autoimmune disorders like rheumatoid arthritis may contribute to the development of this condition. Nevertheless, in some instances, the exact causes remain elusive.

It is important to note that once lung scarring occurs, it is typically irreversible. While medications can help slow down the progression of interstitial lung disease, many individuals may never fully regain their lung function. For select individuals with this condition, a lung transplant may be considered as a potential treatment option. read more

Pulmonary atresia is caused by the abnormal formation of the pulmonary valve, which is responsible for allowing blood flow out of the heart to go to the lungs. The blood flow in that area is obstructed with an excessive tissue lining that causes the valve to be unable to open or close completely. Less blood to the lungs means less oxygen supply in the body.

In general, this congenital heart disease is fatal and can be diagnosed from the time the baby is born. Among babies, there are other natural cardiac channels that allow an amount of blood to flow to the lungs. Although these channels are important for babies when they are still in the womb, they generally close right after birth.

As pulmonary atresia restricts delivery of enough oxygen in the body, the disease mostly causes babies to have blue-colored skin (cyanosis) and treatment is needed, including medications and/or surgery, to improve the heart function. read more

Pulmonary edema is a condition marked by the accumulation of excess fluid within the lungs, which can impede normal breathing. While it is primarily linked to heart issues, other factors like pneumonia, exposure to toxins, medications, chest trauma, or high-altitude activities can also lead to fluid buildup in the lungs.

Signs and symptoms of pulmonary edema include shortness of breath, coughing up foamy mucus, wheezing, chest tightness, and difficulty breathing. Congestive heart failure is a common cause, but it can also occur due to non-cardiac-related conditions.

Immediate medical attention is essential for acute pulmonary edema, a sudden and potentially life-threatening development. The treatment for pulmonary edema depends on its underlying cause. In general, management involves the administration of additional oxygen and specific medications. read more

Pulmonary fibrosis is a progressive lung disease characterized by the scarring and thickening of lung tissue, including the alveoli (air sacs) and connective tissue. This condition deteriorates over time, causing increasing shortness of breath. While some individuals may remain stable for extended periods, others may experience a rapid decline in lung function.

The exact causes of pulmonary fibrosis are often unclear, and when no specific cause is identified, the condition is referred to as idiopathic pulmonary fibrosis. This form of the disease typically affects middle-aged and older adults, although it is rare in children and infants.

Unfortunately, the lung damage from pulmonary fibrosis is irreversible. Treatment options, such as medications and therapies, are aimed at slowing the progression of the disease, alleviating symptoms, and enhancing the quality of life. In certain cases, a lung transplant may be considered. read more
