For educational purposes only
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. See your doctor or endocrinologist for diagnosis and a treatment plan, check your blood sugar as advised, and never change your insulin or diabetes medication, or your diet, without medical advice — changes can cause dangerously high or low blood sugar. Seek urgent care for signs of DKA (very high blood sugar, fruity breath, vomiting, confusion) or severe low blood sugar (shaking, sweating, confusion, passing out — treat with fast-acting sugar and get help). In a medical emergency, call 911.
