I suspected, and you have confirmed my thoughts on this disease. It is a lying-in-wait type of disease that can be set off by probably many factors.triggers. I have a photo of my mother's grandmother who has her hands in her lap. From their appearance, it is possible that she had rheumatoid arthritis -- an autoimmune disease. This picture alone probably bolsters the argument for a gene factor in my own family.
I was told by one rheumatologist that once you get one autoimmune disease, your body is apt to get more. Diabetes is an autoimmune disease and so is thyroid disease - this was new, previously unknown information for me.
I do not know exactly how vitamin B-12 and D are related in this situation, but they must be related in some way. Your body stops wanting to absorb the vitamins needed as it also attacks your immune system. I was told by the last rheumatologist that she had seen people have to be brought into her office in wheelchairs who had low vitamin D. I certainly believed this statement as I had felt like I could not walk either, after many years of having enough energy to work all day and come home and accomplish all that needed to be done and still feel great physically.
I also lived less than 5 miles from a very polluted power plant and their particulate for mercury in the air is high. I would not discount that as a factor either, although there are many people who do get lupus who live no where near such an environmental problem.
The book you mention, entitled Autoimmune Epidemic sounds like something that might help with better understanding. Here is why I say that. My sister-in-law who lives in another state has full-blown lupus, and who is not doing well at all. I have yet another sister-in-law with underlying lupus and now my mother and I both have the underlying lupus. I think it is rather odd to find that many middle-aged and elderly women in one family with two not being related by blood to any of the others, to have this terrible disease. So, I too believe there to be an epidemic of sorts.
It is too bad that we do not know all the triggers to set this disease off and avoid them, but it may be that there are different triggers for different people anyway, but that would be a blessing if someone would start investigating that portion of the whole picture and at least give us the information needed to avoid the triggers we do know about.
Thank you for the book title. I will definitely check that out.
Thank you so much.
