Re: b12 defiency and swallowing
Yes, definitely connective tissue disorders such as lupus, sjorgrens, scleroderma, RA, etc. can cause problems swallowing. Also these are usually autoimmune diseases and autoimmune diseases create autoantibodies. There are several types of specific autoantibodies that can create a B12 deficiency, some of the most common are parietal cell antibodies and intrinsic factor antibodies. These can be present in something called pernicious anemia. Likely your autoimmune disease is connected to your B12 deficiency. That is good that you will be getting weekly shots. Your doctor should probably do some tests to determine if you have an active lupus flare, or what exactly is going on. 10 years is a long time for lupus to go into remission, they should check to make sure your organs are still functioning optimally as sometimes lupus can silently attack certain organs such as your kidneys.
