AIBU to worry my son's tummy aches are anxiety related again?

[Wearebothworriedsick]

DC has struggled with anxiety in the past, this included intrusive thoughts and OCD behaviours. Things have been settled for a few months now.

Over the last week or so, DC has been complaining of a tummy ache. This is only first thing in the morning and around tea time, it’s putting him off eating but then he does eat after a some time. He’s also started sucking his fingers for the first time and pushing boundaries (drew on a wall for the first time and was so upset with himself after).

School think it’s linked to anxiety. I spoke with the GP and they’re inclined to agree although I do worry it might be something physical.

Has anyone experienced this before and how was it resolved?

I am also worried about him losing weight, as well as things getting as bad as they have been in the past. It stopped him going out this morning (cancelled plans) but he was fine the rest of the day, except around tea time.

Things at home have recently changed, I’m aware it will take some time for DS to get used to these changes but it’s hard seeing him like this.

My DS aged 15 is having similar tummy issues.
GP is running some tests but thinks it's IBS from anxiety. GP said its becoming increasingly more common.

I am concerned ex isn’t giving me the full picture. DS said it was like it all the way his time with dad, ex is saying it started a day before being returned to me.

I do have on record DS telling professionals I like him seeing his dad.

DS might get used to it, it’s early days but he’s obviously finding it hard. I’ve sought advice on how to handle it and they’ve said I’m doing everything right but I’m finding it really hard that I can’t fix this despite suspecting what the issue is.

The GP mentioned coeliac to me, which I don’t think is the cause and toileting all normal.

I just don’t want it to get to that stage, having see how his anxiety has escalated before.
