Could asthma attacks just go away?

Lifestyle change. Avoid all milk products since the milk protein causes respiratory tract inflammation. Also avoid grains, lentils. Consume veggies, flesh foods, olive oil. Getting 30 -45 min of sunshine at noon daily or taking vitamin D3 10,000 IU/day and taking a good probiotic (not yogurt) help reduce inflammation Yoga breathing exercises 10-30 min/day help too. This may help avoid the need for meds.
Yes AND NO. Often as children with asthma mature their attacks become less and less frequent to a point where they dont have any attacks. However even though there may saeem to be "no more asthma" it may resurface in adulthood.
