Runny nose is very common type of allergy found in millions of people. It is a nasal discharge that is coming out of the nose. It is secreted by the mucous membranes inside the nose when they get inflamed which is called rhinitis or hay fever. The allergy triggers the production of antibody immunoglobulin E which binds to mast cells and basophils containing histamine. You experience runny nose when you have a cold infection, sinusitis, or flu like illness. The associated symptoms maybe sore throat, breathing difficulty, sneezing, watery eyes, itching near the nose, etc.
The types of allergies are seasonal, environmental, perennial or can be year-round allergy.
Seasonal allergy means when there is a timely change in season or a sudden fluctuation in weather like little rain and then suddenly hot, or cool in the mornings and hot in the days, onset of summer immediately after winter, the period where the summer is at the end and monsoon is in the starting stage, and so on. People with seasonal allergy have to take anti-allergy when they feel that a particular season can trigger the allergy, whereas people who have year-round allergy have to be on chronic anti-allergy to avoid triggering.
Some people experience allergy due to exposure to dust, pollen, animal dander. Some people have allergy to strong smell such as perfumes, detergents, plants. Such people have to keep their nose part of the mouth covered when they are about to be exposed to such odor or smell, or if they suspect some sort of smell they should try and move away from it.
In runny nose, people experience constant discharge from the nose where they have to hold a handkerchief near the nose to clear the discharge.
Runny nose can also be triggered by allergy to stress, less sleep, anxiety also.
Perennial allergy appears throughout the year. It is mainly seen in younger children.
To find out what you are allergic to, you need to take an allergy test. The test may reveal the allergen to which you are allergic to. Skin testing is the most common method of allergy testing.
Remedies to treat runny nose include nasal drops which go enter the nasal passage and heal the inflamed mucous lining. Corticosteroids are good treatment option for nasal congestion. The steroid is to be used in the following way. Close one nostril and tilt your head downward when spraying the steroid.
When a person has a cold due to weather change or infection, he may have associated runny nose which sometimes can be cured by just drinking warm water or warm milk. Elder people who avoid taking medication, often adopt this type of a remedy. When a child gets runny nose can have different colored secretion flowing from the nose like yellow or green. If the secretion or discharge is yellow there may not be need for antibiotic, but if the discharge is greenish it may indicate bacteria interacting with the mucous. This is the point when parents are advised to consult their physician. But again, green mucous is not always a sign of infection. Antibiotics are not necessarily needed at this point also. You may also first try saline nasal drops or vaporizers.
