Question

What is the pathophysiology of productive cough?

**Beginning with etiology, progressing to all changes in structure and function of the system, and concluding with cellular changes.

Answer 1

Ans-

Coughing can have causes that aren't due to underlying disease. Examples include normal clearing of airways, irritants such as smoke and gas, tobacco use or improperly swallowing food and liquids.

Pathophysiology of productive cough--. Productive cough in chronic bronchitis is secondary to excessive mucus secretions in the airways. Mucus is present in excessive amounts owing to the overproduction and hypersecretion of mucus from mucus-producing goblet cells and decreased airway clearance mechanisms.

Ethology--- A wet, productive cough produces sputum (phlegm or mucus from the lungs or sinuses). The cough sounds soupy and may come with a wheezing or rattling sound and tightness in your chest. Most wet coughs are caused by an infection: a common cold, the flu, bronchitis, or pneumonia.

Specific causes of a wet cough include infection and inflammation of the lungs (pneumonia) and bronchi (bronchitis). Other specific causes include chronic obstructive pulmonary disease (COPD), bronchiectasis (destruction and widening of the large airways), cystic fibrosis, and tuberculosis.

All changes in structure and function of the system and concluding with cellular changes----

From green and yellow to red and even black, off-hue mucus can signal everything from pneumonia, TB and, in severe cases, lung cancer.

A productive cough in a person who smokes is often a sign of lung damage. For smokers, the most effective way to treat a cough is to stop smoking. A change in the cough or in the color or quantity of sputum may mean a bacterial lung infection.

Respiratory infections like colds, the flu, and sinusitis are common causes of increased mucus production and coughing up mucus. Allergic reactions are another reason that mucus production can increase. Even consumption of spicy foods can spark excess mucus production in the nasal passages.

Catarrh is usually caused by the immune system reacting to an infection or irritation, which causes the lining of your nose and throat to become swollen and produce mucus. This can be triggered by: a cold or other infections. hay fever or other types of allergic rhinitis.

Usually presents with dry or productive cough and fevers. ... Post-nasal drip (or Upper Airway Cough Syndrome): It presents as dry cough caused by the chronic dripping of mucus from the back of the nose to the throat. Usually after a recent infection or continuous exposure to an allergy trigger.
