Low blood glucose occuring naturally?

I never, to my knowledge, had low blood sugars before I started medications

for diabetes. Are there people out there for whom low blood sugars occur 
naturally? Mine are high without proper foods and exercise, but never low.

They're only low when I take my meds as prescribed, add exercise, and
maybe 
skip or delay a meal/snack now and then.
