Okay so, I posted in a different thread about a sudden weight gain issue and after getting my labs back for thyroid, acth, glucose, b-12 and folate among others the only one that came back abnormal was my vitamin D. My doc told me normal levels should be around 40-50, 8 months ago I was sitting at 35, a week ago I am now sitting at 13 or lower. My docs think that the sudden weight gain could be due to my lack of vitamin D, any ideas??? I’m a really tiny person, I’m short and skinny and although the weight I’ve gained puts me in the middle of the average scale – it’s overweight for my frame and wreaking havoc on my leg joints.
