Strange but true, one of the main causes behind a large number of people suffering from nasal allergy in Bhopal is cockroach. A study conducted by chest specialist Dr Lokendra Dave of Hamidia Hospital blames cockroaches to be the cause of nasal allergy among around 60-70% patients in urban population who underwent immunotherapy Hamidia Hospital.
The allergens produced from cockroaches aggravate asthma and cause allergic reactions in people who are sensitive to those substances.
THIS DUST WHEN INHALED LEADS TO NASAL ALLERGY AND FURTHER LEADS TO ASTHMA
DR LOKENDRA DAVE
“In past four years I analysed the reasons behind the causes of nasal allergy. It was found that around 60-70% patients of urban population were suffering from allergy due to cockroaches. Mostly female cockroaches were responsible for the allergy”, said Dr Dave.
He said, “Almost every week, one or two patients suffering from nasal allergy were tested at Hamidia Hospital. The animal protein found in the body of cockroaches, specifically in their wings and nails, mixes with the dust present in home. This dust when inhaled leads to nasal allergy and further leads to asthma,” he added.
Dr Dave said people were not aware that the uncontrolled population of cockroaches in their residences can recurrent asthma attack. After dust mites, fecal material of cockroaches was one of the major indoor allergen causing nasal allergy.
Cockroach allergens behave like dust mite allergens and stick to heavier particles that quickly settle. These allergens do not remain airborne for long. Activities like vacuuming may stir up allergens that have settled in dust or fabrics. The most common way to inhale cockroach allergen is to breathe in dust or allergens that have collected in pillows, bedding or other dust-trapping fabrics.
Pulmonologist, Dr PN Agarwal said cockroaches may be one of the reasons for aggravating asthma. Some studies done in this regard in foreign universities shows that waste of cockroaches when mixes up with dust and inhaled by asthma patient can lead to asthma attack but it cannot cause asthma.
