Asthma is a condition that affects the air passage that carries air to and from the lungs. People who suffer from such a condition are called "asthmatic". The air passage becomes inflamed, swollen and lined with mucus.
Causes
Asthma could be caused due to changes in temperature, allergens such as pollen, animal hair, dust or smoke. It could also be caused due to stress sometimes.
Symptoms
Asthma could start with a runny nose at first, cough, breathing problems where the air passage becomes narrow and less air passes through it. Then there could be a wheeze which could cause breathing discomfort due to less oxygen reaching the lungs.
Treatment
Asthma has to be treated by a doctor. In the case of children, the mother or caregiver has to be given instructions how to deal with the child when he/she gets an attack. The first thing is to nebulize the child or in some sever cases oxygen is given to ease the breathing. Those would are prone to asthma attacks have to carry an inhaler with them.
Prevention
To prevent asthma attacks, stay away from substances that irritate the air passage and causes breathing problems
