What are the three main types of lung disease?

What is the deadliest lung disease?
Pulmonary fibrosis is a serious, lifelong lung disease. It causes lung scarring (tissues scar and thicken over time), making it harder to breathe. Symptoms may come on quickly or take years to develop. No cure exists.
What is lung tissue?
The lungs are covered by a thin tissue layer called the pleura. The same kind of thin tissue lines the inside of the chest cavity -- also called pleura. A thin layer of fluid acts as a lubricant allowing the lungs to slip smoothly as they expand and contract with each breath.
What are examples of restrictive lung disease?
Examples of restrictive lung diseases include asbestosis, sarcoidosis and pulmonary fibrosis.
What are the 5 obstructive lung diseases?
Types of obstructive lung disease include; asthma, bronchiectasis, bronchitis and chronic obstructive pulmonary disease (COPD).
What's the difference between obstructive and restrictive lung disease?

What are the lungs diseases?
The most common lung diseases include:Asthma.Collapse of part or all of the lung (pneumothorax or atelectasis)Swelling and inflammation in the main passages (bronchial tubes) that carry air to the lungs (bronchitis)COPD.Lung cancer.Lung infection (pneumonia)Abnormal buildup of fluid in the lungs (pulmonary edema)More items...
What can be mistaken for asthma?
Asthma mimickers can be extrathoracic or intrathoracic. Other more common mimickers of asthma include pulmonary eosinophilic disorders, sarcoidosis, hypersensitivity pneumonitis, CF and CHF.
What is difference between asthma and COPD?

Overview
Symptoms
- Asthma symptoms vary from person to person. You may have infrequent asthma attacks, have symptoms only at certain times — such as when exercising — or have symptoms all the time. Asthma signs and symptoms include: 1. Shortness of breath 2. Chest tightness or pain 3. Wheezing when exhaling, which is a common sign of asthma in children 4. Trouble sleeping cau…
Causes
- It isn't clear why some people get asthma and others don't, but it's probably due to a combination of environmental and inherited (genetic) factors.
Risk Factors
- A number of factors are thought to increase your chances of developing asthma. They include: 1. Having a blood relative with asthma, such as a parent or sibling 2. Having another allergic condition, such as atopic dermatitis — which causes red, itchy skin — or hay fever — which causes a runny nose, congestion and itchy eyes 3. Being overweight 4. Being a smoker 5. Exposure to s…
Complications
- Asthma complications include: 1. Signs and symptoms that interfere with sleep, work and other activities 2. Sick days from work or school during asthma flare-ups 3. A permanent narrowing of the tubes that carry air to and from your lungs (bronchial tubes), which affects how well you can breathe 4. Emergency room visits and hospitalizations for seve...
Prevention
- While there's no way to prevent asthma, you and your doctor can design a step-by-step plan for living with your condition and preventing asthma attacks. 1. Follow your asthma action plan.
