There may be a small, unseen creature causing most of your allergy symptoms, called a dust mite. According to the Asthma and Allergy Foundation of America, an estimated 20 million Americans have a dust mite allergy. Dust mites are found virtually everywhere in the world and can survive in various environments. People who are allergic to dust mites can have an allergic reaction even after the mites die, because of their waste and shedding. A person with a dust mite allergy will demonstrate common reactions at the first exposure to the creature.
Nasal Symptoms
A person with a slight allergic reaction to dust mites will experience common allergy symptoms such as sneezing; itchy, water eyes; and swelling around the face. Nasal congestion can lead to postnasal drip, causing an individual to develop a cough. The nasal congestion can manifest in a runny nose, stuffy nose or excessive sneezing. If the nasal congestion is severe and not treated, it can lead to a sinus infection.
Eye Irritation
Eye irritation is another common symptom of a dust mite allergy. The eyes can become red, pink, watery and itchy. A person with a dust mite allergy may rub her eyes in order to relieve the itch, but will only make it worse by irritating the eyes. Watery eyes are another symptom of a dust mite allergy, especially after sleeping or cleaning. Watery eyes can vary in intensity from a glossy look to full-on tears. Eye drops or an oral antihistamine can help to relieve the irritation and redness.
Facial Symptoms
Facial symptoms are common for a person with a dust mite allergy. A person's face may swell or develop itchy red bumps. Many times the area directly under the eyes will swell and develop a bluish color, according to the Mayo Clinic. A person suffering from a dust mite allergy may appear to look tired and fatigued due to facial reactions.
Asthma
Asthma is commonly brought on by exposure to dust mites. The lungs or throat contract, causing difficulty in breathing. If you experience a severe asthmatic response to dust mites, you should seek medical attention immediately. People who feel faint or lightheaded or who are excessively wheezing may need medical attention to open their airway.
Sleeplessness
A dust mite allergy can lead to sleeplessness in some people. Sleep is one of the most important aspects of maintaining a healthy lifestyle and strong immune system. If you are having trouble sleeping due to a dust mite allergy, see a doctor for her recommendation.
