I may have celiac. Not confirmed I had a high Iga level. I started a gluten free diet 2 days ago. How long until I feel better? I have fatigue, joint pain, headache,stomach issuesof diarrhea,bloating, cramps,etc... I feel so bad. I also have low normal b12 and ferritin. Just started b12 shots. I hope someone can answer my questions.
It all really just depends on each individual person. Some feel better almost immediately, others it can take many months. For me personally it took about 2 months before my diarrhea started to go away. Your body has to heal and that can take awhile.
Also, a lot of newly diagnosed celiacs also have problems with dairy so you might want to cut that out of your diet at least for the first month or so and then reintroduce it.
