I suggest you consider yourself celiac based on the positive blood antibodie results. The endoscopy results are not always positive for various reasons. For one thing they can only reach the first 5 feet or so of the small intestine. But the small intestine is around 20 to 22 feet long. So they aren't even testing the majority of it for damage. You could have villi damage at 6 feet and the doctor would never see it.
Antibodies aren't present for no reason. The immune system learns to make them in response to an irritant. And the immune system learns real good. It doesn't forget to make antibodies just because your doctor says something. It'll keep making antibodies and fighting the gluten for the rest of your life. Whenever you consume gluten the antibodies will kick into action and their lifetime is weeks to months. So small amounts of gluten can cause weeks of symptoms.
Otherwise it's all a lot of fun tho. Eating gluten-free gets easier after you've got some experience at it. Some people find that staying away from processed foods for the most part and eating whole foods instead is better at the beginning. The fewer processed foods we eat the less chance of gluten sneaking into the diet there is.
