If you suffer from seasonal allergies, you may experience various symptoms such as a runny nose, sneezing, itchy eyes, and a cough. These are caused by your body’s reaction to an allergen, which triggers the release of histamine. Histamine affects different organs in your body, including your airways. When your immune system tries to defend your airways from an allergen (a substance that irritates your body from the environment), it causes them to narrow and the lining to swell. This leads to more mucus production, and as a result, chest congestion. Chest congestion is the inflammation, narrowing, and accumulation of mucus in your lungs and lower airways or bronchi, which can happen with an allergic reaction. Therefore, the answer is yes, allergies can cause chest congestion.

Allergic reactions that involve the lungs usually occur when you’re allergic to airborne irritants such as pollen or dust mites. The main sign of chest congestion is a wet cough – a cough with mucus (colors can vary), followed by shortness of breath and wheezing. Although, people living with allergy-triggered asthma also experience shortness of breath and trouble breathing, they usually have a dry cough.

Although most mild symptoms do resolve on their own, treatment for allergies that cause chest congestion include:

• Allergen avoidance, for example, if you have a pollen allergy, wear a mask when you’re outside and keep the windows closed during high allergy times (when the pollen counts are at their highest)
• Antihistamines, like Texa Allergy
• Over-the-counter cough medications like a mucolytic (mucofizz), bronchodilators, or decongestants [Read More]
• Prescription medication such as oral or inhaled corticosteroids
• Natural remedies, such as, drink plenty of water to stay hydrated [Read more: 10 Ways to treat your chest congestion at home]

Seasonal allergies can affect your respiratory system in various ways, which can make breathing difficult and uncomfortable. Chest congestion due to allergies can be treated with medication and natural remedies, but consult with a healthcare professional for the best personalized treatment options for you.
