Sorry, that should be co-morbidities, not morbidities (e.g. GI issues, oxidative stress, mito dysfunction, seizures, sleep issues, etc.). Also, there are lot of things that you can do yourself (e.g. diet and nutrition supplementation) by reading or borrowing a basic biomed book. Don't need testing for this as it is trial and error method. Good luck.

Have u tried changing her diet? I dnt know how old she is but for my son changing his diet made a world of difference for him. He's on the gfcf diet along with vitamin supplements. He's bowels are always normal now. She's probably allergic to something she's eating. N reducing sugar in her diet n giving probiotic should help with the yeast. My son is proof that what our children eat can directly effect their brain n health!

Look into the Autism Treatment Network. There is one location in New York at Columbia University. These are specialists in their field that known about the medical morbidities in autism unlike your family doctor or pediatrician. I don't know whether your insurance covers it or even if they will accept anyone with ASD (will likely need referral), but keep trying different docs that will take you seriously and make referrals and do testing.

And if you have the $/capital, you can order a lot of the medical and biomedical testing using sites such as mymedlab.com (they will provide requisition for lab testing) - unfortunately, most of the biomed cannot be sold in the state of New York but can still do routine medical testing, or do the specialized testing out of state.

How frustrating for you, and your daughter!! Are you near a university that might offer some type of clinical trial/study that would offer your daughter help? Or, if you're not too timid, contacting tv stations about your difficulties with lack of community resources and support? I hope you'll hear from someone on this site who has the answers you need!

My son is almost 3 n he's almost 30 lbs so he's not that big. But for him I give the culturelle probiotic suggested by his pediatrician. It's orange flavored so I crush up the tablet n put it in orange juice. He can't tell. And for calcium I just give him vanilla almond milk. It has twice as much as regular milk does. I also give him 1teaspoon super nu Thera. It's a mutivitamin his in magnesium n I think b-12 or 6. For iron I give my son bush vegetarian baked beans, sliced turkey meat, n turkey hotdogs (make sure everything is gfcf). I haven't really tried anything else. I have a list of supplement they say we should be givin iut children but i really dnt find it nessesary yet. I'm just tryna build a bond with him now to encourage social interaction n eye contact. It working pretty well. With good eye contact a lot of social progress can be made! Hopefully i answered ur question !
