Asthma is not a disease but a symptom of some other condition. When a person suffers from asthma, he finds it hard to breathe because there is an obstruction to the flow of air in and out of the lungs.
What causes asthma?
The cause may be an allergy, an emotional disturbance, or atmospheric conditions. If a person develops asthma before he is 30 years old, it is usually the result of an allergy. He may be sensitive to pollens,dust, animals, or certain foods or medicines.
Children, especially tend to develop asthma from food allergies. These are often caused by eggs, milk, or wheat products. People who have asthma are often put on special diets to eliminate or minimize contact with these food products.
