Improvement in blood sugar levels and symptoms are expected to occur in 15–20 minutes, at which point blood sugar should be measured again. If the repeat blood sugar level is not above 70 mg/dL (3.9 mmol/L), consume another 10–20 grams of a carbohydrate and remeasure blood sugar levels after 15–20 minutes. Repeat until blood glucose levels have returned to normal levels. The greatest improvements in blood glucose will be seen if the carbohydrate is chewed or drunk, and then swallowed. This results in the greatest bioavailability of glucose, meaning the greatest amount of glucose enters the body producing the best possible improvements in blood glucose levels. A 2019 systematic review suggests, based on very limited evidence, that oral administration of glucose leads to a bigger improvement in blood glucose levels when compared to buccal administration. This same review reported that, based on limited evidence, no difference was found in plasma glucose when administering combined oral and buccal glucose (via dextrose gel) compared to only oral administration. The second best way to consume a carbohydrate it to allow it to dissolve under the tongue, also referred to as sublingual administration. For example, a hard candy can be dissolved under the tongue, however the best improvements in blood glucose will occur if the hard candy is chewed and crushed, then swallowed.
