That's good that they've identified two treatable nutritional deficiencies. Hopefully you'll be feeling a lot better soon.
When I was diagnosed with non-celiac gluten sensitivity, I was told that having a diagnosed thyroid condition and lab test showing low iron and B12 levels likely meant I had a non-celiac gluten sensitivity - (This was confirmed last year by ruling out celiac disease with the genetic test, though my gastroenterologist stated I should continue eating gluten-free due to the NCGS).
Hope you can completely eliminate gluten from your diet because each exposure triggers your immune system to attack healthy tissue, perhaps for months. The biggest challenge is identifying processed foods that contain gluten.
Another challenge is learning what to eat and not eat when you have a lot of inflammation. Unfortunately, the solution is dietary and physicians receive little to no training in nutrition, so we're on our own to sort out which foods are inflammatory and which are anti-inflammatory. It's highly individual. Hopefully, as you begin to feel better you'll be able to further refine your diet to reduce the inflammation you're experiencing.
Vitamin D plays an important role in managing inflammation. Did your doctor check your D3 levels too? If not, perhaps that should be checked too.
Glad you got some answers. You must be feeling relieved.
This movie tells the story of a nurse who suffered from a B12 deficiency that fought to have chronically ill patients tested for B12 deficiency at the hospital where she worked...

For those who read my posts, I can't afford to see a health practitioner trained in the use of testing, diet, and nutritional supplements to treat my multiple chronic health conditions, so I did the next best thing, I started learning everything I could from the experts by attending health summits and reading books. I use my primary care physician for lab tests and for treatment of acute conditions only. That's the reason I refer people to online and print resources. Informed is empowered.
