Diabetes Caregiving: Helping a Loved One, Chapter 4: Spotting and Treating a Low
Fast Sugar for a Low
Which fast sugars work first during a low, and why a measured portion matters.
Explain how fast-acting carbohydrates raise blood sugar during a low, and why measured portions matter.
A low means the body needs sugar fast. Fast sugar is like fuel poured into an empty tank.
Glucose tablets, juice and regular soda are fast sugars. Tablets usually work within 5 to 10 minutes. Juice and regular soda need 10 to 15 minutes.
Diet soda has no sugar the body can use. It does not help.
Measure a standard portion, not the whole container.
A standard portion is 4 ounces of juice or regular soda. A whole 8-ounce box holds about twice that. The extra can send blood sugar too high later.
Ask your care team how much to give.
Give fast sugar only when the person is awake and can swallow safely. Sleepiness or confusion can mean they cannot swallow safely.
If they are not awake or cannot swallow, put nothing in their mouth. Turn them on their side and call 911.
Key takeaways
- Glucose tablets, juice and regular soda can raise blood sugar within minutes. Recheck after 15 minutes, the common wait for many adults.
- Diet soda has no sugar the body can use, so it does not help.
- A whole box can overshoot, so measure the standard portion.
Try it
Write the portion and recheck time from the low plan on a card you can find fast.
