Asthma OverviewAsthma is a condition in which hyperreactive airways constrict and result in symptoms like wheezing, coughing, and shortness of breath. Causes of asthma include genetics, environmental factors, personal history of allergies, and other factors. Asthma is diagnosed by a physician based on a patient's family history and results from lung function tests and other exams. Inhaled corticosteroids (ICS) and long-acting bronchodilators (LABAs) are used in the treatment of asthma. Generally, the prognosis for a patient with asthma is good. Exposure to allergens found on farms may protect against asthma symptoms.
Chronic bronchitis is a cough that occurs daily with production of sputum that lasts for at least three months, two years in a row. Causes of chronic bronchitis include cigarette smoking, inhaled irritants, and underlying disease processes (such as asthma, or congestive heart failure). Symptoms include
- shortness of breath, and
Treatments include bronchodilators and steroids. Complications of chronic bronchitis include COPD and emphysema.
COPD vs. Emphysema Differences Similarities
COPD (chronic obstructive pulmonary disease) is the term doctors and other health care professionals use to describe a group of serious, progressive (worsens over time), chronic lung diseases that include emphysema, chronic bronchitis, and sometimes asthma. The number one cause of COPD or emphysema, is smoking, and smoking is the third leading cause of death in the US. When a person first develops COPD, he or she may not have any symptoms. As the disease progresses, the symptoms worsen and become more severe and include:
- Difficulty breathing with exertion or physical activity, which in the advanced stages, eventually leads to breathlessness all of the time.
- Chronic cough
- Excessive phlegm production
- Upper respiratory infections like the flu or common cold.
- A barrel-shaped chest
- A bluish tint to the skin from lack of oxygen
- Chest tightness
- varenicline (Chantix) to quit smoking
- The antidepressant and bupropion (Zyban) to reduce nicotine withdrawals
- Drugs that are prescribed for another condition (off label), for example, nortriptyline (Pamelor) and clonidine (Catapres)
- Short-term bronchodilators, for example, albuterol (Ventolin, Proventil)
- Long-term bronchodilators, for example, salmeterol (Serevent) and formoterol (Foradil)
- Anticholinergic bronchodilators, for example, ipratropium (Atrovent) and tiotropium (Spiriva)
- Combined drugs using steroids and long acting bronchodilators
- Roflumilast (Daxas, Daliresp)
You can prevent getting COPD or emphysema if you:
- Quit smoking and making healthy lifestyle changes
- Avoid secondhand smoke
- Avoid home and workplace air pollutants
- Prevent upper respiratory tract infections
There is a genetic cause of COPD called alpha-1 antitrypsin.

Lungs Design And PurposeThe lungs are primarily responsible for the exchange of oxygen and carbon dioxide between the air we breathe and the blood. Eliminating carbon dioxide from the blood is important, because as it builds up in the blood, headaches, drowsiness, coma, and eventually death may occur. The air we breathe in (inhalation) is warmed, humidified, and cleaned by the nose and the lungs.
NeutropeniaNeutropenia is a marked decrease in the number of neutrophils, neutrophils being a type of white blood cell (specifically a form of granulocyte) filled with neutrally-staining granules, tiny sacs of enzymes that help the cell to kill and digest microorganisms it has engulfed by phagocytosis.
