Low Blood Sugar Symptoms: Warning Signs, Numbers and First Aid

Featured card for a low blood sugar symptoms guide showing a label panel with the 70 mg/dL and 54 mg/dL thresholds and the 15 gram first step

Low blood sugar usually starts with shaking, sweating, sudden hunger, a pounding heart and irritability. For many people with diabetes this begins below 70 mg/dL, and readings under 54 mg/dL need action right away. The standard fix is 15 grams of fast carbohydrate, such as 4 glucose tablets, then a recheck after 15 minutes. Call 911 if someone passes out.
