When blood sugar goes too low or too high

For people in the United States who have diabetes; for the mother, father, husband, wife, friend or coworker beside them; and for anyone who may one day be standing next to a person whose blood sugar has dropped. Low blood sugar: the signs, and what to do. What to do when the person can’t treat it themselves. High blood sugar, sick days and ketoacidosis. What diabetes is. Day to day. A program that teaches it. Burnout and mood. Paying for insulin, medicine and supplies. Work, school and driving. Finding help. And the words to say when you call or write. No quiz and no score. One thing at a time.

This page and its wording were written with AI (Claude) for Scarlet Beast (our AI policy). The facts come from pages read on October 2, 2026: the U.S. Centers for Disease Control and Prevention (Diabetes Basics; Type 1 Diabetes; Type 2 Diabetes; Symptoms of Diabetes; Low Blood Sugar; Treatment of Low Blood Sugar; Diabetic Ketoacidosis; Managing Sick Days; Manage Blood Sugar; Monitoring Your Blood Sugar; Your Diabetes Care Schedule; Your Feet and Diabetes; Living with Diabetes; Diabetes and Mental Health; 10 Tips for Coping with Diabetes Distress; Prediabetes; About Diabetes Self-Management Education and Support; and Find a DSMES Program); the U.S. National Institute of Diabetes and Digestive and Kidney Diseases (Low Blood Glucose; and Financial Help for Diabetes Care); the U.S. National Institute on Aging (Diabetes in Older People); MedlinePlus (Hyperglycemia); Medicare.gov (Insulin); the American Diabetes Association (Low Blood Glucose; Signs, Symptoms, and Treatment for Low Blood Glucose; Severe Hypoglycemia; DKA; Insulin Cost and Affordability; Safe at School; Employment Discrimination; Driver’s License Information; Diabetes Care in Detention Settings; and the hours printed on its website); and the Job Accommodation Network (its Diabetes page, and its contact page). The description of Crisis Text Line is from its own front page, read the same day. The American Diabetes Association and Crisis Text Line are private organisations describing themselves; we have no connection with either. We did not call or text any line, contact any provider, program or group, or search any directory. We did not read any clinical guideline, any drug or device label, any law or regulation, any state’s driving, school or insulin rules, what any insurance plan pays for, or the research behind any statement; where the page touches one of these, it says so. Where two pages of one source give different numbers, the page reports both. The page has no questionnaire and gives no score, on purpose: a list is not an assessment. Apart from insulin and glucagon it names no medicine, and it gives no dose of anything; the amounts of juice and sugar are the Centers for Disease Control and Prevention’s. It quotes no named person, and gives no figures for how common diabetes or its complications are; the sources have them, with their context. Lines marked “Ours” are our own suggestions. This page saves nothing: no account, no cookies, nothing you tick is stored or sent, and no analytics (privacy). English only for now. Scarlet Beast is not a clinic or a government agency, and takes no money from anyone named here. Found a mistake? Email [email protected].
