Coughs & Causes
Coughing is a natural reflex that helps clear the airways. But not all coughs are the same. They can vary in type, severity, and cause. Understanding the different kinds of coughs can help you better manage them and know when it’s time to seek medical advice.
Dry Cough (Non-Productive Cough)
Viral infections
The common cold or flu often begins with a dry cough, which may later turn into a productive cough as mucus begins to build up.
Irritants
Exposure to air pollutants, smoke, strong odors, or chemicals can irritate the throat and lead to a dry cough.
Allergies
Exposure to allergens such as dust, pollen, pet dander, or mold can cause a dry cough due to throat irritation or post-nasal drip.
Asthma or Respiratory Conditions
Conditions like asthma can cause inflammation and narrowing of the airways, leading to coughing. These coughs are often dry and may be accompanied by wheezing or shortness of breath.
Post-nasal drip
When mucus from the sinuses drips down the back of the throat, it can trigger a dry, irritating cough. This often happens with sinus infections or allergies.
Gastroesophageal Reflux Disease
Acid reflux occurs when stomach acid flows into the esophagus, which can irritate the throat and lead to a persistent dry cough.
How to manage
To relieve a dry cough, consider using a cough suppressant (antitussive) to help quiet the reflex. Drinking warm tea with honey or using throat lozenges can soothe irritation in the throat. Staying hydrated is key, as it helps to keep the throat moist and reduce the tickling sensation.

Acid reflux occurs when stomach acid flows into the esophagus, which can irritate the throat and lead to a persistent dry cough.
Wet or Productive Cough
Bronchitis
Acute or chronic bronchitis often causes a wet cough. In this condition, the bronchial tubes become inflamed, producing mucus that is coughed up. It’s often accompanied by a feeling of tightness in the chest.
Sinus Infections
Infections in the sinuses can lead to post-nasal drip, which causes mucus to drip down the back of the throat, triggering a productive cough.
Pneumonia
A serious lung infection, pneumonia leads to the accumulation of fluid or pus in the lungs. A productive cough is common in pneumonia and may produce green or yellow mucus. Other symptoms include fever, chills, and difficulty breathing.
Chronic Obstructive Pulmonary Disease
COPD, a long-term lung disease caused by smoking or long-term exposure to pollutants, can lead to chronic coughing and mucus production.
Cold or Flu
Viral respiratory infections like the cold or flu can cause congestion in the lungs, leading to a productive cough as the body works to expel mucus
Cystic Fibrosis
This genetic condition causes thick mucus to build up in the lungs, leading to chronic coughing and difficulty breathing.
How to manage
For a productive cough, expectorants can help loosen the mucus, making it easier to expel. Drink plenty of water to thin the mucus, and avoid suppressing the cough, as clearing the airways is essential for recovery. In some cases, if the mucus becomes too thick, a healthcare provider may recommend a prescription medication to help clear it more effectively.
