Sneezing and Nasal Congestion
The allergens present in house flies can irritate the nasal passageways, leading to frequent sneezing and congestion. The nose often feels blocked, and the individual may experience difficulty in breathing through the nose.
Itchy, Red or Watering Eyes
House fly allergy can cause ocular symptoms such as itchiness, redness, or watering of the eyes. This happens as a defensive reaction from the body to the allergen, resulting in an inflammation of the conjunctiva.
Wheezing and Difficulty Breathing
House fly allergy can impair the respiratory system, causing symptoms like wheezing and shortness of breath. It may be challenging for the affected individual to inhale and exhale fully due to tightened air passageways.
Skin Rash or Hives
Skin reactions, such as rashes or hives, are another symptom of a house fly allergy. The skin may form red, itchy bumps that spread across a larger area of the body, causing discomfort.
Swelling of the Face, Mouth or Tongue
Some individuals may experience facial swelling with special emphasis on the mouth, or tongue due to an allergic reaction to house flies. This might lead to difficulty in swallowing or speaking.
Anaphylaxis
Anaphylaxis is a severe allergic reaction that can occur from a house fly allergy. Symptoms include a sudden drop in blood pressure, rapid pulse, dizziness, or loss of consciousness. It's a life-threatening emergency and requires immediate medical attention.
