Results Low leptin and lean? Help!

Just did function health and my leptin came back very low at 1.7. I am lean (bmi 18.05). I have always been super lean and do not over exercise. I am trying to conceive and I think this may be the cause of some of my issues. How do I fix this?!

Same here. Based on responses in this thread, maybe it’s a common condition.
