Chronic obstructive pulmonary disease (COPD) is a type of obstructive lung disease characterized by long-term breathing problems and poor airflow.

The main symptoms include shortness of breath and cough with sputum production.

COPD is a progressive disease, meaning it typically worsens over time.

Eventually, everyday activities such as walking or getting dressed become difficult.

Chronic bronchitis and emphysema are older terms used for different types of COPD.

The term “chronic bronchitis” is still used to define a productive cough that is present for at least three months each year for two years.

Chronic obstructive pulmonary disease (COPD) is a long-term lung condition that makes it hard for you to breathe.
Types of COPD

COPD is an umbrella term used when you have one or more of these conditions:

Emphysema: This results from damage to your air sacs (alveoli) that destroys the walls inside them and causes them to merge into one giant air sac.

It can’t absorb oxygen as well, so you get less oxygen in your blood.

Damaged alveoli can make your lungs stretch out and lose their springiness. Air gets trapped in your lungs and you can’t breathe it out, so you feel short of breath.

Bronchitis is an inflammation or swelling of the bronchial tubes (bronchi), the air passages between the mouth and nose and the lungs.

More specifically, bronchitis describes a condition where the lining of the bronchial tubes becomes inflamed.

Individuals with bronchitis have a reduced ability to breathe air and oxygen into their lungs; also, they cannot clear heavy mucus or phlegm from their airways.

Fast facts about bronchitis

Bronchitis is inflammation of the bronchi (large and medium-sized airways) in the lungs that cause coughing.

Symptoms include coughing up sputum, wheezing, shortness of breath, and chest pain.

Bronchitis can be acute or chronic.

Acute bronchitis usually has a cough that lasts around three weeks and is also known as a chest cold.

In more than 90% of cases, the cause is a viral infection. These viruses may be spread through the air when people cough or by direct contact.

A small number of cases are caused by a bacterial infection such as Mycoplasma pneumoniae or Bordetella pertussis.

Status Asthmaticus is a chronic respiratory disorder in which a person experiences difficulty in breathing, accompanied by wheezing and a “tight” chest. Additional symptoms can be a dry cough and vomiting (usually in children).

An asthma attack may start suddenly. The fear and worry that this causes can prolong the attack.

Attacks are caused by a narrowing of the small bronchial tubes in the lungs.

The most common kind of asthma (allergic bronchial asthma) is caused by an allergic reaction.

Many pollens, molds, dust (especially dust containing the house mite), and animal hair and dander can cause allergic-type asthma attacks.

Asthma is thought to be caused by a combination of genetic and environmental factors. Its diagnosis is usually based on the pattern of symptoms, response to therapy over time and spirometry.

It is clinically classified according to the frequency of symptoms, forced expiratory volume in one second (FEV1), and peak expiratory flow rate.

Treatment of acute symptoms is usually with a short-acting broncodilator and oral corticosteroids.

In very severe cases, intravenous corticosteroids, magnesium sulfate, and hospitalization may be required.

Symptoms can be prevented by avoiding triggers, such as allergens and irritants, and by the use of inhaled corticosteroids.

Most of us possess hypersensitive problem but we are lacking any knowledge about this.

Allergies are unusual immune reactions to particular agents known as antigens or allergens.

Instances of standard allergens are foods, drugs, pollens, dust mites, mold spore, animal dander, feathers, and insect venoms, and other compounds that non-allergic people find relatively non-dangerous with common exposure.

Allergic reactions may also develop if an otherwise harmless substance has substantial contact with a previously inflamed area, such as from a viral infection or exposure to irritants, and becomes active in the immune reaction.
