What Causes Allergic Rhinitis?

Allergic rhinitis occurs when your immune system reacts to particles (allergens) in the air that you breathe by causing an allergic reaction such as sneezing, inflammation and a runny nose.

Causes of Allergic Rhinitis

There are two types of allergic rhinitis - seasonal and perennial.

Perennial allergic rhinitis, which can occur all year round, is usually triggered by indoor allergens, such as pet dander, dust mites, dust, mould and occasionally food allergy.

Seasonal allergic rhinitis is seasonal and is caused by outdoor allergens such as pollen from trees and plants. There may be a genetic or hereditary factor involved. If your parents have allergies,you might also have a predisposition to have allergies. The chance is higher if your mother has allergies.


A Comprehensive Allergy Test can be done at our medical clinic. Please make an appointment for a consultation with Dr Don Lau at Tel: 6694 1661.

Comprehensive Allergies Test for up to 101 allergens:
* Food Allergy eg Seafood, Nuts, Eggs, Fish, Meat, Fruits, Seeds or Vegetables.
* Dust/Mold Allergy
* Insect Sting Allergy.
* Pet/Cockroach Allergy.
* Eye or Skin Allergy
* Sinus Infection/Allergic Rhinitis
* Drug/Latex Allergy


Symptoms of Allergic Rhinitis

You may have symptoms only at certain times of the year if you are allergic to pollen. If you are allergic to indoor allergens or dust mites, you may have symptoms all the time.

Symptoms can be similar to that of the common cold but unlike a common cold, they continue over a longer period. Symptoms include:

• Continual sneezing, especially in the mornings

• Runny nose and postnasal drip

• Watery and itchy eyes

• Blocked stuffy nose

• Ears, nose and throat that are itchy

People with allergies usually have symptoms for many years. Some conditions such as asthma and eczema can also be associated with allergic rhinitis. There may also be other problems such as sinusitis and ear infections as a result of your allergies.

Recognising symptoms of Anaphylaxis (Severe Allergic Reaction)

  • Itching, swelling of lips
  • Itching, tightness, stridor (high-pitched, wheezing sound caused by disrupted airflow), hoarseness
  • Itching, hives, redness and swelling
  • Rapid breathing, cough, wheeze
  • Giddiness, weak pulse, pale, clammy, loss of consciousness

Seek immediate medical attention. Call 995 for emergency ambulance. Ensure that the person is lying down in a safe location, keeping airway patent and maintaining breathing.

How a Gluten-free Diet can Improve your Chronic Illnesses

Healthy Diets for Optimal Health

Alessio Fasano MD - Spectrum of Gluten-Related Disorders: People Shall Not Live by Bread Alone

The cultivation of gluten-containing grains that were the backbone of the agricultural revolution have also brought with them the manifestation of conditions related to negative reactions to gluten. These include celiac disease, wheat allergy and the "new kid on the block" of the spectrum of gluten-related disorders—gluten sensitivity. The autoimmune disorder of celiac disease is the most widely studied condition on the spectrum. It affects approximately 1 in 133 people, a rate that has doubled in the U.S. every 15 years over the past 35 years. An estimate from the Center for Celiac Research puts gluten sensitivity at 6% of the U.S. population. With current interest in the human genome and microbiome, research is leading scientists to examine the relationship between the intestinal microbiome and gluten-related disorders. Currently the gluten-free diet is the only available treatment for gluten-related disorders.

World-renowned pediatric gastroenterologist, research scientist, and entreprenuer Alessio Fasano, M.D., founded the Center for Celiac Research in 1996. The Center offers state-of-the art research, clinical expertise and teaching for the diagnosis, treatment, and prevention of gluten-related disorders, including celiac disease, wheat allergy, and gluten sensitivity. Trained in Naples, Italy, as a pediatric gastroenterologist, Dr. Fasano was recruited to the University of Maryland School of Medicine in 1993 and founded its Division of Pediatric Gastroenterology and Nutrition. Puzzled by the absence of children exhibiting symptoms of celiac disease in the clinic, he resolved to uncover the mystery of missing American "celiacs." His perseverance in the face of skepticism about celiac disease in the U.S. eventually led to his publication of the groundbreaking study in 2003 that established the rate of the autoimmune disorder at one in 133 Americans.

In early 2013, Dr. Fasano was appointed Division Chief of Pediatric Gastroenterology and Nutrition at MassGeneral Hospital for Children. He brought the Center for Celiac Research to Boston, where he heads the Mucosal Immunology and Biology Research Center, based in Charlestown, and is Associate Chief for Basic, Clinical and Translational Research for the Department of Pediatrics at MassGeneral Hospital for Children. He is a Visiting Professor of Pediatrics at Harvard Medical School.
