Hi Beth, Welcome to the board.
You could just be taking a while to heal, or you could be getting a fair bit of gluten in accidently. If you post a sample of what you usually eat maybe we could try to pin down any culprits. You wouldn't believe all the things they put gluten in! If we don't find any foods (or medications) in your daily diet, then it could be an additional illness or just delays in the healing process and relief of symptoms. Some people do take months and even years before getting real relief.
You say you only had blunted villi, but no other symptoms. I would say your "nature calls" are a symptom. Did you have this problem before going gluten-free? Also there are over 250 known symptoms and related diseases to Celiac, so maybe you had some and didn't realise they were related. But I wouldn't say that you are "partly diagnosed". You had a positive biopsy. This is undisputable evidence that something is damaging your intestines. Do the doctors think it is gluten doing the damage or something else? If it isn't gluten what do they think it would be??
And another question, are you still consuming dairy products?? If your villi are blunted, then you will not be able to digest any dairy, since the tip of the villi is where the enzymes to digest lactose (milk sugar) are located. If you don't have the tips back yet, then the dairy will give you problems. You may need to give up dairy for at least a few weeks, possibly a few months.
Looking forward to seeing your food "diary".
God bless,
Mariann
