Asthma

Asthma is a condition, in which a person’s airway becomes inflamed and they have trouble breathing as a result. The airway gets narrow and swells thus producing extra mucus. This condition is called Bronchial Asthma in medical terms. In an estimate, four out of every 100 adults suffer from this condition and it widely varies from countries. Vietnam records the low asthma rate followed by Austria and Sweden. According to the World health organization (WHO), India experiences about million asthma cases, where 15 percent are children. Thus three out of every 100 adults have asthma in India.

Classifications of Asthma

Asthma can be mild, need no medication, or very little care would be sufficient. But in some cases, it could be severe and life-threatening. Based on the frequency and severity of asthma medical professionals classify asthma into the following four types
Mild intermittent asthma: Here the symptoms are invisible or mild. You will have symptoms for two days in a week or two nights a month. But it won’t affect any of your daily activities.
Mild persistent asthma: The symptoms occur more than twice but not daily and may occur four nights a month.
Moderate persistent asthma: The symptom occurs daily on days but at least one night a week and affects your activities.
Severe persistent asthma: Here your daily activities are mostly limited, as the symptoms occur all days and nights.

Causes of Asthma

Not a single cause is directly related to asthma. But researchers believe some factors depend on your breathing conditions.
Genetics: If your parent or grandparents, your sibling have asthma you are more likely to get.
Viral infections: If you had a severe viral infection during your childhood, your probability of getting asthma will be high.
Hygiene hypothesis: Overprotection of babies affects their immunity. Babies should be exposed to bacteria at their younger age to strengthen their immune system. If not their system won’t have the ability to fight with asthma and other allergies.
