Can being overwhelmed mean you throw up? Does anyone else with ASD or an autistic child relate to this?
My 7 year old daughter (awaiting ASD assessment) goes through phases where she keeps throwing up. It only happens at night and seems to be related to her feeling emotionally overwhelmed. She went through weeks of it last year after the death of a family pet. At that point every night she would start to get sad when she needed to go to sleep, then she'd panic that she was getting sad (as if the emotion was too big for her to handle) and then she'd throw up. What made it worse was after this had happened on a few nights she started to worry that it would happen and that seemed to make it more likely. This went on for a few weeks and we tried a range of things - having me sleep next to her, reading special books, talking about the things that were upsetting her and wearing car sickness bands - when it became apparent that it wasn't a tummy bug. Eventually it went away.
But now it's started again. This week she got really upset because one of her regular groups has stopped running, changing her weekly routine, and she lost a milk tooth. She was very sad about the group and very excited about the tooth and at about midnight, after she'd been asleep for several hours, she vomited in her bed. I don't think she noticed for awhile, or maybe wasn't bothered, because by the time we got to it it had started to dry (TMI, sorry). We had to change all her bed linen, turn the mattress, put a vomit covered soft toy in the wash (which upset her more than anything else) and shower her/wash her hair. The following night she got upset because she had got into trouble and instantly threw up. I did everything I could to calm her down and made sure she felt safe, and we got her to bed. But a couple of hours later she ran to the bathroom and threw up again.
She has no other symptoms during this time and when she throws up it seems to catch her by surprise, so I don't think she feels ill leading up to it, and once its happened she's fine, all chatty and happy. She's not off her food at all during the day and is perfectly active and herself.
I've Googled and the only thing that comes up is Cyclical Vomiting Syndrome (CVS) and she doesn't fit the other symptoms, as these episodes are irregular and she feels generally well (no fever, stomach pain etc) both before and after she throws up.
I'm pretty sure that her being sick is rooted in her emotional state, and I wonder if this is could be related to autism. I know I often become unwell when I'm feel overstimulated or overwhelmed, though it usually has to be either highly traumatic or a sustained stressful situation, and it can land me in bed for days, and I wondered if she could be experiencing something similar and whether it is a known phenomena among those with autism or some sort of physical thing akin to a meltdown or a shut down maybe?
