This guide is educational information about blood sugar and diabetes — it is not medical advice, diagnosis, or treatment, and it is not a substitute for care from a qualified professional. It does not diagnose, treat, cure, reverse, or prevent any condition. Never change medication, insulin, or diet without your doctor — especially if you take glucose-lowering medication, as changes can cause dangerously low blood sugar. Individual results vary. In a medical emergency, call 911.
