As far as your cholesterol goes - it's not freakishly low. If you told me you had a good family history (no heart disease) and ate a really healthy diet, I probably wouldn't make much of it.
That being said - there are some medical issues that can cause low cholesterol - including malabsorption (another reason to check for celiac disease) and hyperthyroidism (another autoimmune condition, probably worth checking also).
I used to have a very low cholesterol (120's) when I was a skinny vegetarian in my 20's - but also it's possible, in retrospect, that it was an early subclinical sign of the hyperthyroidism I developed a few years later.
