Medication Alert: Beta‑Blockers & Hidden Lows
Like the wolf in Red Riding Hood, beta‑blockers can disguise your body’s adrenaline alarm, making hypoglycemia harder to notice.
- Blunted warnings: fast heartbeat, tremor, and anxiety may be muted; sweating can still happen.
- What to do: rely on your meter/CGM and treat lows right away—don’t wait for symptoms.
