Do High-Functioning ASD Kids get Sick More Often?

Do ASD kids, even high-functioning ones, get sick more often?

My kid, TsukiMoon  is home sick again today.  He has missed several days of school this year to illness.  He was sick during the Christmas holidays and now, little less then a month later here he is sick again.  What's the deal?

This blog post is really more like sending a question out into the universe and see if an answer comes back.

During the holidays we vacationed in Yellowstone.  It was great but hard to carry on with the; no-dairy, no-gluten food plan.  Our child almost only eats meat and carbs.  We tried to do our best but in a place where you have to pack in all your gear, we rode in snow-cats to get to the cabin we stayed in, extra food is difficult to add.  So we just winged it.  Our take away is that either his sickness caused lots of upchucks or TsukiMoon has totally lost the ability to process dairy.  Without fail he would have a stomach clearing puke after eating dairy earlier in the day.

Never one with a strong stomach, TsukiMoon has been able to vomit, almost at will, his whole life.  When he was a baby he had serious reflux that would cause him to; nurse, have a powerful projectile puke (usually on me), then nurse again.  My breasts were HUGH, as though I was feeding twins.  The reflux went away by about the time he was a year old but the sensitive tummy did not.

Any cold that causes coughing will bring up lunch.  I have said to my husband that at least when he won't over-drink in college because his body will reject anything foreign easily.

He had a fever 2 nights ago, but being MLK on Monday he didn't have to go to school the next day.  We did take him to his regular Monday appointment with Mrs. K, the speech and language pathologist.

He works better for her when he eats.  She feeds him because he always proclaims to be "starving,"  even after having a huge meal in the car on the way there.  The food is not on the meal plan though, so the previous Monday I left several Trader Joe's treats with her for him to snack on while be taught.  I think he over ate.  Over-eating is easy for TsukiMoon to do since he seems to lack or not read the feed-back from his stomach.  Late that evening after going to bed he didn't disappoint and nuked his bed and the floor of the bathroom with ick.

Ok, so is he sick because he gets condition makes him more sensitive to germs or did he eat too much in the late afternoon causing us to have to do laundry at 10pm that night?

I don't know and I don't know how to help him.
