Celiac can take quite awhile before it shows up via bloodwork, unfortunately. Food intolerance issues such as gluten or diary can both be very hard to pin down. Most people believe they should see a 1-to-1 pattern: eat the food and see symptoms. No so. In many cases there can be a delay of days to weeks so it can be hard to find the correlation.
If you think either gluten and/or diary could be an issue, take one of them out of your diet for several weeks and see what happens. If you believe nothing has changed, add it back over several days time and again watch. If you're okay, then take the other one out.
Dairy also contains a protein that can cause major food problem. The protein is casein, and the lactose test won't show you have problems with that.
If you've got joint achiness, I'd really suggest you take gluten out of your diet. It's the one 'food' that seems to result in a myriad of symptoms including joint pain. If you don't want to do an exclusion diet, at least have your genes checked for the presence of celiac and/or gluten-sensitive genes. You can do it yourself through enterolab.com. We tracked down my husband's gluten and dairy problems via enterolab, and further verified his gluten status via the same company when the standard medical tests failed. He's well and happy.
No rashes, no brain fog, celiac test was done by blood work, twice and loctose was done by drinking something n blowing into a tube for 3 hours every half hour, this was also done twice, both came back negative twice. Only history is lactose intolerance, sveral people do but as i said its come back negative twice and i never have problems with dairy products. It doesnt matter what i eat ive still have the same prob since july when it started. Only autoimmune disease is mom m she has rheumatoid arthirisris in her hands and elbows n i know thats deff not it, my achiness isnt that bad n im onlg 19
Any rashes? How about 'brain fog?' How did the doc test you for celiac disease - specifically which test was used? Any history of food intolerances in your family or celiac disease? Any other forms of autoimmune diseases?
