Also monitor for high blood sugar: increased thirst, frequent urination, fatigue, or fruity-smelling breath. Keep fast-acting glucose (juice, glucose tablets) readily available. When to seek emergency help: Severe confusion, loss of consciousness, seizures, or blood sugar below 54 mg/dL that does not respond to treatment. Inform your prescriber about all medications to adjust diabetes medication doses if needed.
