According to World Health Organisation estimates, between 100-150 million people worldwide suffer from asthma of which 15-20 million belong to India.
As per a WHO report on World Asthma Day today, the fundamental cause of asthma, that is characterised by recurrent attacks of breathlessness and wheezing is not completely understood, but the strongest risk factors for developing asthma include indoor allergens like dust mites in bedding and carpets.
Dr Prahlad Prabhudesai, Chest specialist at Lilavati Hospital here cautioned that there may be some people who do not show qualities like breathlessness but may still be suffering from 'silent Asthma', which cannot be prevented as it is a hereditary disorder.
"There is no medicine available to prevent asthma. Only the attacks can be prevented. There are some patients who do not show any qualities of being an asthmatic. People who frequently sneeze or periodically cough may also be asthmatic. They need to get a diagnosis done at the earliest," he said.

"Asthma cannot be cured but it can be controlled. People suffering from asthma can learn to identify and avoid the things that trigger an episode and educate themselves about medication. With proper treatment, people with asthma can have fewer and less severe attacks," Dr Joshi said.
