Asthma is an ancient greek word. It means ‘panting or short drawn breath’. It is an allergic reaction of the body to one or more allergens.
Asthma is a very troublesome respiratory disease. An asthma patient gets frequent attacks of breathlessness, in between two attacks the patient may be normal.
Symptoms of Asthma
Persons suffering from asthma gasp for breath and they find it more difficult to exhale than inhale. This is caused by spasms or unexpected involuntary muscular contractions of the minor air passages of the lungs.
The effect is to blow the lungs up because the patient cannot drive the air properly out of the lungs before he/she has to take another breath.
Usually asthma patients have more difficulty in breathing at night or early in the morning. Other symptoms include:
- Dry , rattling cough
- Over accumulation of mucus
- Difficulty in catching the breath especially from exertion, or being indoors in stuffy rooms
- Coughing even to the point of expelling mucous
- A trickle in the throat triggering a cough, especially when trying to take a deep breath
Causes of Asthma
Allergic reaction to weather conditions ,and many other factors contribute to asthma. It may be due to sensitivity caused by food, drugs, perfumes and other irritants.Foods which normally cause allergic reactions are egg, milk, beans, wheat, fish , sea foods and chocolates. Hereditary is also a cause of the disease.
Allergy to dust is very common cause for asthma.
Asthma may be caused due to psychological factors too. It is found that around 25% of young asthmatics have a emotional insecurity and intense need for parental love and protection.
