I have Celiac disease and IBS. I have lost 13 lbs the past year and am struggling with trying to gain it back . It seems I gain a few pounds then suffer a flare and lose it

I was just wondering does anyone experience body aches and fatigue with IBS? Last night after I went to sleep I started having body aches and was like NO!! I can.t get sick... I did have a flare up yesterday and it when on all day and apparently through the night with the aches and then this morning too. I've been on a light diet since yesterday. Just curious if body aches is normal. I feel so sleepy and run down

I know personally I retain a lot of fluid during my flare ups. But I've gained and I really don't eat much when I do. I've gain up to 20lbs being sick and all I can do is sleep through it.

It's come about over the last few months where my fingers are swollen and the joints sore mainly on my right hand. Also it seems to be affecting my shoulder and neck. For many years I've had lower back issues and sciatica.

Has anyone else been diagnosed with SIBO? I've rarely seen it mention when researching IBS, but the new doctor I went to yesterday suggested a modified fodmap diet that eliminates additional foods to address it. You can get tested for SIBO but I decided to just start treatment right away without confirmation of the test, because I am so desperate to feel better.
