This is another study that dispels the myth that glyphosate is safe: "Pesticides and prostate cancer incidence and mortality: An environment-wide association study": https://acsjournals.onlinelibrary.wiley.com/doi/10.1002/cncr.35572 

Welcome to the forum, @Kiwifruit! Were you on a reduced gluten diet when those blood tests or the biopsies were done?

Hi everyone. I have a history of GI issues (gas, diarrhoea, pain, fatigue). In 2018 I had a a blood test that returned “weak positive” for Celiac (I don’t have access to this result) and in early 2018 I had an endoscopy. The dr said by appearance he believed it would be Celiac but biopsy said no. 2022 I had another blood test with results: Anti TTG IgA: 27 units (norm 0-20) high IgA: 0.9 g/l (norm 0.8 - 4.0) Endomysial antibodies: neg I had a colonoscopy and endoscopy and had the same abnormal appearance but negative biopsies. All my dissachrides were low so I was referred on to a dietitian. I am still struggling with all my GI issues but now with nausea, brain fog and weakness/joint pain even following the low disaccharide diet with enzymes. I’m now pondering my previous results and see that all 3 low disaccharides can also be an indicator of Celiac. I’m struggling and so confused and wondering if anyone has any guidance or advice for me? Thank you     

I agree with @RMJ and unfortunately different celiacs have different trigger levels for gluten, and some celiacs have little or no symptoms at all when exposed to gluten.

In people with celiac disease, gluten can trigger migraine headaches, and we have a category of research summaries on this topic: https://www.celiac.com/celiac-disease/celiac-disease-amp-related-diseases-and-disorders/migraine-headaches-and-celiac-disease/
