Depends but rare: Blood sugars below 50 can be lethal. Rapidly decreasing blood sugar can cause cardiac arrhythmia and increase risk for death. There is no simple answer to your question. Best to treat blood sugars below 80, and monitor blood sugar for trends. If you use insulin, talk to your doctor about this issue. Small frequent intake of food is a good start. Be well.
