14 Common Causes of Itchy Throat

2. Food Allergies 

Sometimes the body reacts to certain foods as if they were toxic substances that can harm it. When your body acts ‘weird’ after taking certain foods, it might be because of an allergic reaction. This means that your body has ‘blacklisted’ the particular food and whenever you ingest it the body’s defensive mechanism is put on high alert of an impending invasion. The protocol is clear; releasing histamine to neutralize the threat.

Histamine would cause an immediate contraction of the smooth muscles and dilate the capillaries as if it was responding to an injury or an inflammation. Because there is no real threat, one begins experiencing symptoms like sore throat among others that result from the response to the false alarm. Some allergies can be mild and normalcy would resume after a short while. Others, however, can be life-threatening and one should quickly see the doctor when the symptoms persist. The common triggers of food allergy include peanut, fish, eggs, and wheat, among others.
