সংজ্ঞা

A cough is a sudden expulsion of air from the lungs. Its purpose is usually to clear secretions and inhaled foreign substances from the lungs and respiratory tract.

There are different types of cough:

  • Acute cough—lasts for less than three weeks
  • Subacute cough—lasts 3-8 weeks
  • Chronic cough—lasts longer than eight weeks

কারণসমূহ

An acute cough is usually caused by an infection, such as a cold or flu. In some cases, an acute cough can be the sign of other conditions, such as:

  • Exposure to an irritant or an allergen
  • Aspiration of a foreign body
  • ব্রংকাইটিস
  • নিউমোনিয়া

Subacute cough is often a cough that follows a respiratory infection. It can also be caused be exposure to irritants or to anything that can cause chronic cough.

A chronic cough can be caused by many factors. Common examples include:

  • Chronic obstructive pulmonary disease (COPD) (eg, chronic bronchitis,emphysema)
  • হাঁপানি
  • Reflux of acid from the stomach into the throat (gastroesophageal reflux disease [GERD])
  • Postnasal drip, which may be due to:
    • Repeated inhalation of environmental irritants
    • Sinus inflammation
    • এলার্জি
  • Bronchiectasis (a less common cause)
  • Certain medicines (eg, ACE inhibitors)

ঝুঁকির কারণ

The main risk factor for cough is being exposed to irritants, for example:

  • তামাক সেবন
  • Noxious fumes
  • Allergens, such as pollen and dust
  • Smog and other environmental pollutants

Smoking is a major risk for serious conditions linked to chronic cough, including lung cancer and COPD.

Acute cough is usually diagnosed by its accompanying symptoms.

During the diagnosis, your doctor will look for symptoms that suggest an underlying cause. Tests may include:

  • Chest x-rays —a test that uses radiation to take a picture of structures inside of the chest
  • Computed tomography (CT) scan of the chest—a type of x-ray that uses a computer to create images of structures inside of the chest
  • Analysis of a sputum sample
  • Blood test to check for infection
  • Skin tests if allergies are suspected
  • Skin test for tuberculosis
  • Pulmonary function tests —to measure lung volumes and air flow rates
  • Bronchoscopy —insertion of a long, thin instrument to view the interior of the airways and collect samples

চিকিৎসা

The best treatment for a cough is to treat the underlying condition.

ঔষধ

There are many over-the-counter (OTC) cough and cold products available. Examples include decongestants, expectorants, antihistamines, and antitussives (cough suppressants).

বিঃদ্রঃ: The Food and Drug Administration (FDA) recommends against using OTC cough and cold products to treat infants and children younger than four years old. Rare but serious side effects have been reported, including death, convulsions, and rapid heart rate.

জীবনধারা পরিবর্তন

Consider putting a steam vaporizer or cool-mist humidifier in your room. This type of moisture therapy may help to make secretions looser and easier to cough up.

If you smoke, talk to your doctor about strategies to quit. Smoking affects your lung function and increases your risk of many diseases.

If you are diagnosed with a cough, follow your doctor’s instructions .
