And you could be one of his victims and not even know it. The allergist discusses the little-known but highly annoying phenomenon of allergic cold.
Do you often have a runny loop, frequent sneezing attacks at a particular time of day, which can sometimes go up to 400-500 sneezes and a stuffy nose almost all year round? And you resigned yourself to being stuck with this common cold & # 39; which doesn’t seem to leave you?
If you have these symptoms and take a cold more than three times a year, you probably don’t suffer from the common cold caused by an allergen. Doctor called allergic rhinitis, this type of cold is often mistaken for the common cold.
How do you tell the difference?
- First of all, the common cold is a viral infection, that is, caused by a virus, where an allergic cold is an allergic reaction.
- The common cold lasts about a week. During this time, the body’s immunity was usually unable to overcome the virus while the allergic attack is more persistent.
- A person can catch a common cold about once or twice a year. If the allergen stays around, allergies may be perennial.
- A common cold has many more generalized symptoms: pain, fever and headache. These are absent in allergies. However, sneezing and watery and itchy nose are common to both.
How is an allergic cold caused?
Although the root cause is still unknown, scientists suspect a genetic defect or susceptibility. The immediate cause is usually a trigger like:
Pollen: Being light, these small flower particles float in the air and are easily carried by the wind. Some types of pollen, due to their chemical composition (amino acid and protein content) are more allergic (i.e. they cause allergies). The beautiful fragrant flowers that are pollinated by insects are generally harmless. It is the inconspicuous wild flowers that grow among the herbs (such as cynodon, the small white flowers of the meadow grass) that are the main culprits. Many children, after playing in the grass, return home to smell the cold.
insects: of the 50,000 mite species, D. flour, a domestic mite, is the main culprit. It thrives in the hot and humid climate and is commonly found in wool rugs, rugs and old cotton mattresses. An average mattress can have 50,000 to one hundred thousand mites. It is not only the inhalation of mites but also the inhalation of its body parts and faces which could cause an allergic cold.
When cockroaches die, they do not decompose but turn into dust and mix with the dust in the air, adding to the allergen present in the air.
Molds: They usually thrive in city landfills. Being extremely light, they are easily transported by drafts to wet areas such as old leaking buildings. They can also be found on the connection of refrigerators (the small black dots that we mistake for dirt).
Pets: The tiny particles found in animal hair (hair) and bird hair are a common cause of allergic colds. Hairy Pomeranian, parrots and pigeons are the main criminals.
Professional risks: Grain manipulators are affected by wheat dust and those who work in a cotton factory can develop allergic colds in response to cotton fibers.
Food: Children are usually allergic to milk, adults to grams and seafood.
What does the typical cold allergic patient look like?
A person suffering from an allergic cold has a worried expression. This is because during an attack his eyes can be sore from an infection of conjunctivitis and the tip of the nose is often red and bulbous due to constant rubbing and swelling. He may also have a nasal blow, an arid and breathless mouth. It may have a crease over the tip of the nose when performing the allergic greeting. rubbing the nose upward to relieve irritation in the nasal passage. This irritation is caused by histamines, one of the most important chemicals released by nasal mucus cells in response to allergy. It is the histamine that is responsible for sneezing and watering the nose.
Who are most susceptible to allergic colds?
Children from the age of three to puberty are the most sensitive because their immunity is not mature enough to fight allergens at this time. The number of children suffering from allergic cold is 15% higher than adults. During childhood, the body’s ability to produce the IgE antibody (and therefore to cause an allergic reaction) is high. As we age, IgE production decreases favorably. Those who suffer from asthma, gastrointestinal allergy or eczema are also more sensitive to allergic colds because, even in these patients, IgE is elevated.
On the other hand, 30 percent of cold allergy sufferers can develop asthma after five or ten years.
Does climate play a role in the occurrence of allergic cold?
In northern India, allergic colds are common in winter when the air is dry because the humidity drops, drying the nasal mucus and trapping the infection. (Normally, mucus and eyelashes – brush-like structures in the nose prevent bacteria, viruses or allergens from entering.)
Allergic colds are high during the rainy season when humidity is high. This moisture in the air hinders the movement of the eyelashes, making them slow and increasing the chances of infection. Comparatively, summer is the least annoying period, with the exception of the risk deriving from the pollen of the flowers that bloom in this season.
However, a person who has an allergic cold all year round is usually in constant contact with an allergen, such as food, mites or animal hair.
What is the incidence of allergic colds in the general population?
Of the 20 percent of the general allergy-sensitive population, half, that is, 10 percent, suffer from allergic colds.
How is relief achieved?
A doctor usually prescribes nasal drops, antihistamines and steam inhalations for symptoms such as sneezing and watery nose. If the patient (usually one who suffers from perennial allergic colds) develops tooth tumors called polyps in the mucosa (nasal membrane), they can be removed with surgery.
A doctor can perform an allergy test (RAST Radio Allegro Sorbent Test) together with a blood test to detect the allergen. Depending on the type of allergy, he can prescribe medications such as Cromolyn, Ipratropium or Beclomethazne.
Can allergic colds be prevented?
Exercises such as Pranayama (yogic breathing), walking or jogging are recommended because the improvement of respiratory circulation makes the eyelashes more effective in removing allergens. Antiallergic vaccines can be given to desensitize a person to a particular allergen.
