What is cough, its symptoms, and its treatments?
What is a cough?
A cough is a reflex action that helps clear the airways of irritants, mucus, or foreign substances.
It is a common and protective mechanism of the respiratory system.
When something irritates the throat or air passages, the body responds by expelling air forcefully to remove the irritant and clear the airway.
Various factors can trigger coughing and can serve different purposes:
Irritants:
Common irritants that can trigger a cough include dust, smoke, pollen, pollutants, strong odors, and chemical fumes. When these irritants enter the respiratory tract, they can stimulate coughing to remove them.
Infections:
Respiratory infections, such as the common cold, flu, bronchitis, or pneumonia, can cause coughing.
Infections lead to increased production of mucus, which the body tries to expel through coughing.
Postnasal Drip:
Excess mucus from the nose or sinuses can drip down the back of the throat (postnasal drip), leading to irritation and coughing.
Allergies:
Allergic reactions to allergens like pollen, pet dander, or dust mites can trigger coughing as the body’s response to remove the allergens.
Asthma:
People with asthma may experience coughing as a symptom of bronchial constriction and inflammation in the airways.
Gastroesophageal Reflux Disease (GERD):
Stomach acid can flow back into the esophagus, leading to irritation and coughing, a condition known as acid reflux-induced cough.
Medications:
Some medications, particularly those that affect the angiotensin-converting enzyme (ACE) pathway, can cause a persistent dry cough as a side effect.
Chronic Conditions:
Chronic coughing can be a symptom of underlying medical conditions like chronic obstructive pulmonary disease (COPD) or interstitial lung disease.
Coughs can be classified into different types based on their duration and characteristics:
Acute Cough:
An acute cough lasts less than three weeks and is often associated with viral infections like the common cold.
Subacute Cough:
A subacute cough lasts between three and eight weeks and can result from post-infectious inflammation or other factors.
Chronic Cough:
A chronic cough persists for more than eight weeks and may be due to various underlying causes, including allergies, asthma, GERD, or chronic respiratory conditions.
Coughing is typically a protective mechanism, but persistent or severe coughing can indicate an underlying health issue.
If you have a cough that is prolonged, worsens over time, is accompanied by other concerning symptoms (such as chest pain, difficulty breathing, or blood in the sputum), or interferes with your daily life, it is advisable to consult a healthcare professional for evaluation and appropriate treatment.
What are the symptoms of a cough and its treatments?
The primary symptom of a cough is the reflex action of forcefully expelling air from the lungs to clear the airways.
However, coughs can vary in terms of their characteristics and accompanying symptoms depending on the underlying cause.
Here are some common symptoms and characteristics associated with different types of cough, try to get proper treatments:
Dry Cough:
This type of cough produces little to no mucus or phlegm. It often feels scratchy or ticklish in the throat.
Wet or Productive Cough:
A wet or productive cough brings up mucus or phlegm from the lungs or airways.
It is often seen in respiratory infections and conditions where excess mucus is present.
Persistent Cough:
A persistent cough lasts for an extended period, typically more than three weeks.
It may be indicative of an underlying medical condition, such as chronic bronchitis, asthma, or GERD.
Coughing Fits:
Some individuals experience sudden and intense bouts of coughing, often triggered by irritants or allergens.
These fits can be severe and disruptive.
Barking Cough:
A barking cough is a distinctive, harsh, and dry cough that can occur in children with croup, which is usually caused by a viral infection.
Hacking Cough:
A hacking cough is often dry, repetitive, and forceful. It may occur with conditions like bronchitis or pneumonia.
Nighttime Cough:
Coughs that worsen at night can disrupt sleep and may be associated with conditions like postnasal drip, asthma, or GERD.
Blood in Cough (Hemoptysis):
Coughing up blood can be a concerning symptom and may indicate various conditions, including infections, lung disease, or pulmonary embolism.
Seek immediate medical attention if you cough up blood.
Accompanying Symptoms:
In addition to the cough itself, the underlying cause of the cough can lead to other symptoms, such as:
Sore Throat:
A sore throat may occur with a persistent cough, particularly if the throat becomes irritated from coughing.
Chest Pain:
Coughing can sometimes lead to chest discomfort or pain, especially with forceful and frequent coughing.
Fever:
Coughs due to infections like the common cold or flu may be accompanied by a fever.
Shortness of Breath:
Coughing can cause shortness of breath, especially in individuals with conditions like asthma or chronic obstructive pulmonary disease (COPD).
Wheezing:
Wheezing, a high-pitched whistling sound during breathing, may occur with certain cough-inducing conditions, such as asthma.
Runny or Stuffy Nose:
In respiratory infections, a cough may be accompanied by nasal congestion, a runny nose, or sneezing.
It’s essential to pay attention to the specific characteristics of your cough and any accompanying symptoms, as this can provide clues about the underlying cause.
If you have a cough that is persistent, severe, or associated with concerning symptoms like chest pain, difficulty breathing, or blood in the sputum, it is advisable to seek medical evaluation for proper treatments.
A healthcare professional can diagnose the cause of the cough and recommend appropriate treatment.
What are the causes of a cough?
Coughs can have various causes, and the underlying factor often determines the type and characteristics of the cough.
Here are some common causes of coughs:
Viral Infections:
Viral respiratory infections are a frequent cause of coughs. Common examples include:
Common Cold:
Rhinoviruses and other respiratory viruses can cause a cough, along with symptoms like a runny or stuffy nose, sore throat, and sneezing, so seek proper treatments.
Influenza (Flu):
Influenza viruses can lead to a cough, often accompanied by high fever, body aches, and fatigue.
Bacterial Infections: Bacterial infections of the respiratory tract can also result in coughing. For example:
Bronchitis:
Inflammation of the bronchial tubes can lead to a productive cough with mucus production.
Pneumonia:
Bacterial pneumonia can cause a cough along with symptoms like high fever, chest pain, and difficulty breathing.
Allergies:
Allergic reactions to airborne allergens, such as pollen, pet dander, dust mites, or mold spores, can trigger coughing.
This is often referred to as allergic or allergic rhinitis-induced cough.
Asthma:
Asthma is a chronic respiratory condition characterized by airway inflammation and bronchoconstriction. Coughing, especially at night or early morning, can be a prominent symptom of asthma.
Gastroesophageal Reflux Disease (GERD):
Acid reflux from the stomach into the esophagus can lead to irritation and coughing, a condition known as acid reflux-induced cough.
Environmental Irritants:
Exposure to environmental irritants, such as tobacco smoke, air pollution, strong odors, or chemical fumes, can irritate the respiratory tract and lead to coughing.
Postnasal Drip:
Excess mucus from the nose or sinuses can drip down the back of the throat (postnasal drip), causing irritation and coughing.
Chronic Conditions:
Some chronic respiratory conditions can lead to persistent coughing, including:
Chronic Obstructive Pulmonary Disease (COPD):
This includes chronic bronchitis and emphysema.
Interstitial Lung Disease:
Various lung diseases can lead to chronic coughing.
Bronchiectasis:
A condition characterized by damaged and widened airways.
Medications:
Certain medications, particularly those that affect the angiotensin-converting enzyme (ACE) pathway, can cause a persistent dry cough as a side effect.
Vocal Cord Dysfunction:
Dysfunction of the vocal cords can lead to a chronic or recurrent cough, often triggered by specific activities or stress.
