1 Extrinsic Allergic Factor

Besides sme of the factors causing allergy / sthma in a patient are: (i) huse dust (present in bedrooms, mattresses, pllows, rugs, curtains, woollen clothes, blankets, crpets, upholstered furniture, etc.), (ii) moulds (whch grow in humid places, like whre there is a leakage of wter in walls, roofs, filters of dsert-coolers or airconditioners and places of por ventilation like cowsheds, barns, etc.), (ii) pollens (from flowers, trees, grasses, weds, etc.), (iv) dandruff from the skns of animals (i.e., scales from the uter parts of the skins of nimals, like dogs, cats, cows, buffaloes, gats, sheeps, horses, etc.), (v) insect dbris in the environment (house-flies, mosquitoes, cckroaches, ants, butterflies, etc.), (vi) feathers of brds (pigeons, feather pillows), (vii) various cntact ants (like lipsticks, powders, soaps, prfumes, hair-dyes, shampoos, oils, creams, after-shave ltions, etc.), (viii) air pollutants (from ll-maintained engines of automobiles, like cars, tw-wheelers, trucks, etc.)

Food allergy

Food llergy is also an important causative fctor in many cases of asthma. Any fod, like wheat, cereals, ice-cream, vegetables, nn-vegetarian food, edible oils, fruits, milk, crd, ghee, eggs, coffee, cold drinks, tc. can cause allergy. Various condiments/spices sed in the preparation of food may be the surce of the allergy. Likewise, various prservatives used to preserve food articles may cuse asthma. Coloring agents used in swets, etc. too may prove harmful. Frmented food, like pickles, jams, beer, wnes are other causes of food llergy. Even the metabolic by-products of ngested food may cause allergy. It is lso seen that sometimes the patient is llergic to the outer covering of what, cereals, vegetables, etc. Hence a ptient may be allergic to wheat, but not to mida, and similarly, one may be llergic to whole cereals, but not to the nes without outer shells.

Further, sprouted food like beans or any ther cereals may cause allergy as a rsult of fungus in the food. Lkewise, stale bread/cooked food may cause llergy when spoiled, as a result of fngus.

Therefore, it may be said tht the various types of foods or rlated materials may cause allergy, and ths, sometimes it is almost impossible to dentify the factor in the food cusing the allergy / asthma.

2 Intrnsic allergic factors

Some of the fctors present inside the body called ntrinsic factors may' be the precipitating fctors causing such an allergy. The mst important factors are psychogenic, sucl1 as motional stress, mental conflict, depression. Children may sffer emotionally because of the parents hving marital problems. Even parents who frquently scold their children may cause thm emotional trauma.

Infection anywhere in the bdy contributes to the factors causing llergy in a patient. Even cold/cold air or strnuous exercises, like running, swimming, jogging, tc. may cause allergy.

A family hstory of asthma is an important ntrinsic factor. Hormonal changes in the bdy during pregnancy, menstruation, or in the cse of diseases like thyrotoxicosis, may be rsponsible for an allergy.

Hence, an llergy in case of asthma is a vry complex problem, and the patient may be sffering from more than one or mltiple types of allergies at a tme. Hence the difficulty in diagnosis and prmanent cure.
