It's a proper disease & an extremely unpleasant disabling disease that could affect quite a large number of people, most of them still undiagnosed. It wasn't diagnosed properly before, people were just sick & didn't know why, it'd be called 'IBS' or whatever, or misdiagnosed as some other autoimmune disorder, but medical science keeps progressing & now they know it's an immune response to gluten, for those lucky enough to be diagnosed before it causes serious damage.
It's hard to diagnose because there are so many different symptoms, it can affect every part of the body, every organ.
It's nothing to do with how bread is made or any of the bs in the post above, gluten is a protein found in all wheat, barley & rye. Coeliac disease is an autoimmune disease that causes the immune system to react to gluten in the diet. Corn & soy are totally fine.
My dad can't walk because of gluten ataxia, try telling him its a fad, in fact you can't really tell him anything because he has dementia caused by gluten too. For over 30 years he was told it was just colitis, he hasn't been able to leave the house for 5 years, wasn't even tested for coeliac until last year, now it's too late for him, it'll be a long slow death.
I'm feeling a lot better now, a year after going gluten free, I'm slowly starting to gain weight & look healthier, but I still have problems caused by it that might never heal properly. I'm still at a higher risk of several other serious illnesses like cancer & osteoporosis.

If people think it's a fad diet then they're stupid, if they try to go gluten free to lose weight or whatever that's even dumber, but it helps that safe food that wont poison me with gluten is becoming more widely available. I still don't feel safe eating out & try to cook all my own food from basic ingredients. If I want to go out for more than a few hours I have to plan ahead & take my own food, sometimes it can be hard to even find a snack that is safe for me to eat.
It's fucking irritating that people think it's a fad or make up a load of bullshit to try to explain it, like Foreigner did. You wouldn't question a nut allergy or even lactose intolerance, I don't understand why coeliac gets such disrespect. You've no idea how badly it's affected me & others with the condition.
It's a genetic condition, with some as yet unknown environmental trigger. A large proportion of people have genes that mean they could develop coeliac. It's estimated that around 1 in 100 people in the UK have coeliac disease, higher in Ireland, but as most are undiagnosed it could be more prevalent.
