If one parent has asthma, your offspring have 50%chance of having asthma...2 parents and that can be increased to 70-90%.
This does not mean they "have to" suffer from this.
More asthma is common in the world now, due to pollution, more cars, trucks on the road, the ozone layer, and more population, more viruses and so on.
Now, I was always told avoidance is a good way to eliminate things that cause allergies. For ex. I am allergic to dust, dust mite droppings, so I have to keep my house as dust free as possible. I dust with a wet cloth, so the dust gets grabbed and not stirred around into the air. I removed carpet from most of our rooms and this summer we hope to get the carpet off the bedroom floors...it is easier to run a swiffer mop or a damp mop to get all the dust and keep the mites away.
My son who suffered so much when little and even had exercise induced asthma too, is now much improved. He has grown out of it..this can happen...but not always.
I got asthma at age 30...my mom has asthma, and siblings too. Now mine is well undercontrol with Flovent...I still carry my rescue inhaler, and thank God I don't need it.
Ezcema, is not uncommon in asthmatics...my son gets it in his hairline, my sister has it with large patches on her elbows, her daughter has it in her ears, my mom has it on her scalp...along with my brothers too, my older soster has a mild case, and I get it once in awhile it will flare up on my left palm and in between my fingers...no cure for it, just creams and lotions.
I hope some of this info helped you.
Take care, & here's to breathing easy!
