I can sense your desperation. it's horrible to be living a full life and then suddenly it comes to a grinding halt. Just a few bits of advice from someone who's walking the same road. a. doctors do the best they can but they actually know very little, especially with diseases like this that cross physician specialist boundaries. Also, with the sore throat and some of your other symptoms, I would tell your doctor to run a thyroid panel (blood test). Often, people with celiac develop an underactive thyroid (hypothyroidism) which exacerbates many symptoms including gi bloating and discomfort. Next, pack on the (gluten free) supplements. Your gi tract is not absorbing what you need (which causes depression and brain fog), but taking vitamin supplements will help your system absorb more. Focus on ferrous fumerate (iron), vitamin B complex, zinc, magnesium, vitamin d, and a standard full range multivitamin. Take these daily for a long time until you feel improved. take the iron w/ vitamin c by itself on an empty stomach. These vitamins will be a bridge to you until your gi tract heals (up to 6 months or more). Stay persistent with your doctor, do research and tell him what you need. Walk into his office with a list of questions. He/she will pay more close attention to your case if you show you are engaged, intelligent and seek concrete, scientific answers, and show persistence. Also, you need probiotics. ALIGN brand is the only one that has 50% success rate in a double blind study. Take it every day for a few months at least. Lastly, AVOID GLUTEN LIKE POISON. It is really everywhere. YOu will need to become vigilant and eat nothing that comes from a package or bottle unless it is labeled gluten free. use whole foods in your meal prep- items that come to you in the form they grew, single ingredient type items. Don't eat anything you haven't prepared, even if your friends say it is gluten free. People who don't have celiac don't understand how important it is to not even consume a trace amount.
