Every year, approximately 2 out of every 100 individuals in the United States living with diabetes and using insulin—or medications that stimulate the pancreas to release insulin—may face episodes of severely low blood sugar, also known as hypoglycemia. This condition can be sudden, intense, and dangerous if not addressed quickly.
Beyond these statistics, it’s important to understand that blood sugar levels can fluctuate multiple times throughout the day due to factors such as meals, physical activity, stress, or even missed medication. These fluctuations are especially common among those managing diabetes and can increase the risk of developing low blood sugar without warning.
Because of this, it’s critical to adopt proactive habits like regular glucose monitoring, maintaining consistent eating patterns, and being prepared with fast-acting carbohydrates at all times. Recognizing your body’s unique patterns and warning signs early can help you respond effectively before symptoms escalate.
If you or a loved one is navigating diabetes, understanding how to prevent and manage low blood sugar should be a top priority.

How to Manage Low Blood Sugar Levels Safely and Effectively
If you begin to feel shaky, sweaty, dizzy, confused, or notice any other symptoms of low blood sugar, the first step is to check your blood glucose level right away. These symptoms can develop quickly and may indicate that your blood sugar has dropped below your target range—specifically, under 70 mg/dL, which is considered hypoglycemic.
When managing low blood sugar, one of the most reliable and widely recommended methods is the 15-15 rule. This approach involves consuming 15 grams of fast-acting carbohydrates, then waiting 15 minutes before rechecking your blood sugar levels. If your reading remains below 70 mg/dL, repeat the process until your levels return to a safe range. Once your blood sugar stabilizes, it’s essential to eat a small meal or snack to help prevent another sudden drop—especially if your next full meal is still more than an hour away.
Effective 15-gram carbohydrate options include:
Four glucose tablets or one tube of glucose gel (check packaging for exact carb count)
½ cup (4 oz) of fruit juice—apple, grape, or cranberry juice are preferred options. Avoid orange juice if you have kidney concerns due to its high potassium content.
½ can (4–6 oz) of regular (non-diet) soda
1 tablespoon of honey, table sugar, or corn syrup
A specific number of hard candies or jellybeans (refer to food labels for portion size and carb content)
Always choose simple, fast-digesting carbs when treating low blood sugar. Complex carbs, fiber-rich foods, or anything high in fat (like chocolate) can slow down sugar absorption and delay recovery.
After consuming a fast-acting carbohydrate source, wait 15 minutes and recheck your glucose. If your levels are still low, consume another 15 grams of carbohydrates and check again. Repeat until your reading is at or above 70 mg/dL.
If it’s going to be more than an hour before your next scheduled meal, have a balanced snack—like a small fruit with crackers or a piece of toast with peanut butter—to help maintain steady blood sugar levels and prevent rebound hypoglycemia.
Properly managing low blood sugar episodes requires not just quick action, but also preparation. Keep glucose tablets or a suitable carb source with you at all times, especially during exercise or travel. Being ready can prevent a minor drop in blood sugar from becoming a medical emergency.
Keep track of any instances of low blood sugar and discuss the cause with your medical staff.
Treating Low Blood Sugar When Taking Medications That Slow Digestion
Some medications prescribed for diabetes—such as GLP-1 receptor agonists or amylin analogs—are designed to slow down digestion, helping to reduce post-meal spikes in blood glucose. While these drugs can be highly effective in managing blood sugar levels, they also present a specific challenge when treating low blood sugar (hypoglycemia).
If you’re taking one of these medications and experience symptoms of low blood sugar—such as dizziness, shakiness, or blurred vision—it’s important to understand that not all carbohydrate sources will work equally to restore your glucose levels quickly. Because digestion is intentionally slowed, foods or drinks that require breakdown in the stomach—like fruit juice, soda, or candy—may not raise your blood sugar fast enough in an emergency.
In these cases, only pure glucose sources—such as glucose tablets or glucose gel—are reliable for rapid absorption. These products are specifically formulated to bypass the delayed digestion effect and enter the bloodstream more efficiently. Acting quickly is essential to avoid complications such as fainting, confusion, or even seizures.
If you’re managing diabetes with medications that impact gastric emptying, it’s a good idea to:
Always carry glucose tablets or gel with you, especially when away from home.
Educate friends, coworkers, or caregivers on what to do if you have a severe low blood sugar episode.
Wear a medical ID bracelet indicating your condition and medication use.
Consult your healthcare provider regularly to review your risk and update your emergency plan.
Understanding how your medication interacts with low blood sugar response is a critical part of staying safe and empowered in your diabetes management journey.
In case of an emergency
What if I am unable to treat myself and have an extremely low blood glucose level?
The best treatment for extremely low blood glucose is glucagon, a hormone that increases blood glucose levels. Glucagon, which is available as an injectable or a nasal spray, swiftly increases blood glucose levels. You can get a glucagon kit from your doctor to use in an emergency.
You won’t be able to treat a low blood glucose level on your own. Prepare yourself to deal with extremely low blood sugar by:
- determining the best time to use and how to use a glucagon emergency kit by speaking with your doctor or medical staff.
- instructing your loved ones, close friends, and coworkers on when and how to administer glucagon. If they give you glucagon or if you don’t have a glucagon emergency kit with you, tell them to phone 911 straight away.
- wearing a medical alert necklace or bracelet. A medical alert ID notifies others that you have diabetes and require immediate care.
Receiving timely medical attention might help avoid the serious issues that low blood glucose levels can bring about.
Prevention of Hypoglycemia if you have Diabetes
Let’s assist you in avoiding low blood glucose levels if you take insulin or other medications that lower blood glucose.
- Checking your blood glucose level should be discussed with your doctor or medical staff. The use of a blood glucose meter is the most popular method for doing this. A continuous glucose monitor (CGM) can be an excellent choice if you frequently experience low blood sugar or have hypoglycemia unawareness. Your blood glucose level is regularly measured by the CGM, and if it falls outside of your intended range, an alarm may be set off.
- Make sure your regular eating schedule consists of meals, snacks, and beverages with enough carbs to help maintain your blood glucose level within the desired range. Bring a source of quick-acting carbohydrates with you, like glucose pills or a juice box. Additionally, it is safer to have meals at the same time as alcoholic beverages.
- Be careful when exercising. Your blood glucose can get low during and after exercise. To prevent low blood glucose, you might need to check your blood sugar levels before, during, and after exercise and ask your doctor to modify your medication or carbohydrate consumption when you work out. For instance, you might consume a snack before exercising to avoid low blood sugar.
- To avoid low blood sugar, work with your doctor and medical staff. Adjust your diabetes management plan; learn more about the effects of your diabetes medications on blood sugar levels and how you can prevent and treat hypoglycemia symptoms.
Hypoglycemia can be dangerous if you let it go unnoticed. Together with your healthcare team, make a record of your blood glucose, insulin, diet, and exercise data to figure out the reasons for hypoglycemia. You can easily prevent hypoglycemia by adjusting your diet, mealtimes, your workout routine, and the timing of insulin dosage.
