My dad's crazy mother (she literally becaem crazy) first said I was type 1 because we had a cat (1984). About 6 to 9 months later it was because we had a microwave. Why do I have no siblings with Type 1? Someone from church told me it was because I was eatign too much sugar. My brothers ate way more than I did.
No diabetes anywhere in my family, but if you go along my family tree, you can find plenty of autoimmune diseases RA, PBC, AFAP, and severe allergies (some people conisder severe allergies to be autoimmune). I recently read that lack of vitamin D levels are common in people with autoimmune diseases. I asked my dr to check and it was at 13. I guess 50 to 100 is normal, but the docs worry if you drop below 30. I wonder if spending too much time inside and the shade has kept us from getting enough vitamin D. As time goes along, we spend more and more time in our cars and buildings. Sun through car windows doesn't count for vit D absorbtion.
