Asthma is a chronic disease, wherein the bronchial tubes constrict the inflow and outflow of air in the lungs due to chronic inflammation and swelling, causing breathlessness and wheezing. It also triggers excess mucous production, which further irritates the air passageways. As a result, oxygen supply to the bloodstream and organs reduces alarmingly.
“Mildness and severity of the condition vary in every individual. Immediate medical attention is needed only in severe cases. Severe asthma attacks can be life-threatening and fatal in severe cases. Further, it can cause COPD (a chronic obstructive pulmonary disease which causes inflammation and damage to the lungs) and emphysema (where the lung’s air sacs are damaged, as seen usually among smokers)”, Dr Angeli Misra, Director, Lifeline Laboratory said.
Asthma cannot be cured. It can only be controlled. Appropriate medical management can help keep asthma under control.
The prevalence of asthma in India is estimated to be about 2% among adults and 6% among children. A majority of children generally outgrow the chronic condition once they reach adulthood. Comparatively, more males suffer from it at a younger age than females. It is interesting to note that the prevalence of asthma is more common among women than men in general.
