The throat, the ring-like muscular tube, containing the pharynx and larynx, plays a very important role in respiratory, ingestion, and speech function. Any abnormality related to the throat, whether caused by bacteria, virus, allergens, or any underlying conditions, affects your day-to-day life. One such very common abnormality is the sore throat, also called pharyngitis– an infection caused by cold or flu virus, bacteria like streptococcal, or several types of allergens. Sore throat caused by virus heals naturally and bacterial infection may require antibacterial medications, what if the cause of sore throat is allergies?   

Runny or stuffy nose, fatigue, coughing, and sneezing are common symptoms of infection caused by viral, bacterial, and allergic reactions. But if the symptoms include fever, swollen lymph nodes of the neck, and muscular pain then the underlying cause might not be an allergic reaction. If you have an itchy throat, watery eyes, along with other symptoms then it could be an allergic sore throat and it normally lasts longer.

If your immune system is weak to endure seasonal changes, then seasonal allergies might develop oral allergy syndrome in response to eating certain foods. Allergic reactions to certain food allergens may cause itchy mouth, scratchy irritated throat, and swelling of lips and mouth. Seasonal allergy-induced sore throat is very common and it could be effectively treated with some medication and home remedies.

Allergic Sore Throat and Effects

One of the most common symptoms across all age groups is the itchy throat—mostly caused by a reaction to certain allergens. It is important to understand what type of allergens irritates your throat leading to scratchy feeling and ensuing discomfort in swallowing. Here are some of the common allergens and their side effects to help you prevent allergic sore throat:

Postnasal Drip: Exposure to allergens like pollen grains and seasonal changes can trigger allergic response leading to nasal congestion and sinus darning down to the throat. Excessive draining could cause coughing, irritation, speech difficulty, and result in tickling or scratchy pain in the throat. Besides seasonal irritants, you might be extra sensitive to allergens like dust mites, mold or mildews, pet dander, and smoke.

Food Allergy: Several people experience allergic reactions to certain food items, like peanut butter, dairy, or strawberries. Consuming allergy-causing food items triggers an immune system response in your body, resulting in primary symptoms like nasal congestion, teary eyes, and in extreme cases asphyxiation. If not treated in time, it could be fatal.

Pollutants: Anything that is not fit for the human body triggers the auto-immune response. One of the biggest culprits of the modern era is the chemical pollutants that could trigger allergic reactions leading to a sore throat. So, if you are experiencing an aggressive immune response to certain chemicals like cleaning products, pesticides, or paints you should better maintain a healthy distance from such irritants to keep your throat safe.
