Advair Diskus and shock

My 15 y.o. daughter has has first hand experience with weight gain on Advair. About 6 years ago at about 9 y.o., she gained 20 lbs in 6 months - and it started happening exactly when she started the drug. She was very active (swim team, gymnastics, etc) and did not overeat. It is very frustrating that both her pediatrician and her asthma/allergy specialist deny that her small dose of Advair is to blame.

For some reason, and I have talked to others that this has happened to, switching to Singulair did not help her with the weight problem. Seems the people who are hypersensitive to inhaled steroids are also sensitive to Singulair. Concerned about her rapid weight gain, and because she was always so thin, I took her to an endocrinologist to rule out any other problems. After a lot of bloodwork, he concluded that he could not rule out that it was a side effect of the Advair and/or Singulair, and that they may have elevated her blood sugar. I have read tons and tons of postings on the internet about children & adults rapidly gaining weight from inhaled corticosteroids (i.e. Flovent, Advair), along with the round face, bloated stomach, stretch marks, thin skin, easy bruising, etc. but nobody ever says what happens after stopping any of these drugs. Do people ever go back to normal? Do kids look like themselves again? Do any of the side effects disappear?

She is now 15 y.o. and cannot reverse her weight gain no matter what (30 lbs overweight). The last 2 years, she has only been on a small dose of Pulmicort (a different class of corticosteroid even safe to take when pregnant) since she has mild persistent asthma, and allergy shots have helped trememdously. My husband and I have been looking for 6 years now on how to avoid our daughter's weight gain with asthma drugs. If you run into any info., please let us know. Any experiences or info would be greatly appreciated. Thanks!
