Dry cough is a cough that does not produce any mucus or phlegm. It can be caused by a variety of factors, including:
- Viral infections: The common cold, flu, and other viral infections can cause a dry cough.
- Allergies: Allergies to dust, pollen, or other substances can cause a dry cough.
- Environmental irritants: Exposure to smoke, pollution, or other irritants can cause a dry cough.
- Acid reflux: Acid reflux can irritate the throat and cause a dry cough.
- Asthma: Asthma can cause a dry cough, along with wheezing and shortness of breath.
- Medications: Certain medications, such as ACE inhibitors used to treat high blood pressure, can cause a dry cough.
Treatment for a dry cough depends on the underlying cause. Some common approaches include:
- Over-the-counter cough suppressants: Over-the-counter cough suppressants, such as dextromethorphan, can help relieve a dry cough.
- Honey: Honey has natural cough-suppressant properties and can help soothe a dry cough.
- Steam inhalation: Inhaling steam from a hot shower or humidifier can help soothe a dry cough.
- Avoiding irritants: Avoiding exposure to smoke, pollution, or other irritants can help reduce a dry cough.
- Treating underlying conditions: Treating underlying conditions, such as allergies or acid reflux, can help reduce a dry cough.
If you have a persistent or severe dry cough, it's important to consult with a healthcare professional for proper diagnosis and treatment.
