First have you been tested for celiac? A blood test is needed to test for it. You can splurge on gluten or just have a half slice a bread a day but you have to keep eating it for the testing. 12 weeks for the blood test. 2 weeks for the endoscope where they will check your intestines for damage and take biopsies. Make sure you get the FULL celiac panel.
I suffered from what seemed like minor symptoms since child hood that I never even linked to it....constipation, randomly vomiting after some meals I thought was normal, slowly degrading mental capacity, all kinds of little mental issues. degrading health (very slow). Bunch of random flags now that I think back on it. But it did not go full blown huge symptoms til my 20s, sorta did something stupid and gave a shock to my immune system and kicked in the full on gene I guess. But it quickly went to MAJOR mental and nerve damage effects, basically I lost feelings in my hands sorta would randomly go turn into Mr. Hyde and start yelling screaming and punching things, I was constipated for 10+ days at a time, always gassy and bloated and randomly bed ridden with gut wrenching pains. We are all different in symptoms as it is a AI disease.
But yes it can seem to ramp up from minor symptoms to much much worse and pronounced ones. If you do indeed have celiac then it is slowly damaging your insides every time your exposed, destroying the insides of your intestines. In my case it also causes my immune system to go after the nervous and brain, thus causing brain damage, confusion, and extreme irritability.
It took me 20 years or more Barry so I wouldn't claim any great insight on this I had a 'eureka' moment, up until then I was walking around with multiple symptoms and not connecting any dots whatsoever. It is very, very difficult to diagnose and that's something that's reflected in so many of the experiences detailed here.
A food diary may help in your case. It helped me to connect the gaps between eating and onset. It could help you to track any gluten sources should you go gluten free.
It is possible for your reactions to change over time. As to whether its celiac, that's something you could explore with your doctor, stay on gluten if you choose to go that way.
best of luck!
