After You Have Low Blood Sugar
If your low blood sugar was mild , you can return to your normal activities once your blood sugar is back in its target range.
After you have low blood sugar, your early symptoms for low blood sugar are less noticeable for 48 to 72 hours. Be sure to check your blood sugar more often to keep it from getting too low again, especially before eating, physical activity, or driving a car.
If you used glucagon because of a severe low , immediately call your doctor for emergency medical treatment. If you have had lows several times close together , you should also tell you doctor. They may want to change your diabetes plan.

Treating Low Blood Sugar
You are at risk of having a low blood sugar reaction if you:
- Skip or delay a meal or snack
- Take too much insulin or eat too few carbohydrates
- Drink alcohol, especially without eating carbohydrates
Check your blood sugar if you have any of these symptoms:
- Weakness and/or fatigue
If your blood sugar is less than 70 milligrams per deciliter :
- Eat 15 to 30 grams of carbohydrate
- Wait 15 minutes and then recheck your blood sugar
- If your blood sugar is still less than 100 mg/dl, take another 15 grams of carbohydrate and retest your blood sugar in another 15 minutes. Repeat if necessary.
Important: If you have frequent low blood sugars speak to your doctor. You may need changes in your medication and/or meal plan.
Best Foods For Low Blood Sugar
For patients with diabetes, monitoring blood sugar levels is a part of daily life.
Low blood sugar, or hypoglycemia, can occur for many people with diabetes who are on certain medications, including insulin and sulfonylureas. It can occur for a variety of reasons including skipping a meal, exercising strenuously, taking too much insulin or consuming alcohol, especially on an empty stomach.
Low blood sugar can be as minor as a slight inconvenience or as serious as a life-threatening emergency. Thats why it is important to boost blood sugar before it becomes problematic.
Angela Norton, a diabetes educator at Sharp Chula Vista Medical Center, has diabetes herself, so she knows firsthand the tips and tricks of keeping blood sugar on track. Although blood glucose is considered normal if above 70 mg/dL, Norton says patients with diabetes should not wait until they reach below that threshold to take action.
Treat when you feel the symptoms, even if your blood sugar is not below 70, because as long as it is less than 100, it may be dropping fast, she says.
When it comes to treatment, Norton shares these five foods to help boost low blood sugar.
1. CandyWhen hypoglycemia occurs, patients should follow the 15-15 rule. Consume 15 grams of carbohydrates to raise blood glucose and check your levels again after 15 minutes. When the numbers return to normal, eat a snack to stay on track.
Gummy candies contain carbohydrates, which have a large impact on blood sugar levels.

When To Go To The Er
High blood sugar can be very concerning because your body can start burning fat for energy instead of blood glucose.
This can cause conditions such as DKA and hyperglycemic hyperosmolar syndrome . These conditions are medical emergencies and can be fatal if left untreated.
DKA is a serious complication of type 1 diabetes. Its rare in people with type 2 diabetes, but can occur.
Symptoms that can indicate you should go to the emergency room include:
- ketones in your urine, as diagnosed using a urine dipstick test
High blood sugar levels can cause a fluid imbalance in the body and can cause the blood to become acidic in a manner that doesnt support life.
Medical treatments for these conditions include administering intravenous insulin on a continuous basis and IV fluids to correct dehydration.
High blood sugar can become a medical emergency. Go to the ER if you suspect DKA or HHS.
What Should I Do If I Have Symptoms Of A Low Blood Sugar Level
- Check your blood sugar level, if possible. Your blood sugar level is too low if it is at or below 70 mg/dL.
- Eat or drink 15 grams of fast-acting carbohydrate. Fast-acting carbohydrates will raise your blood sugar level quickly. Examples of 15 grams of fast-acting carbohydrates:
- 4 ounces of fruit juice
- 4 ounces of regular soda

The Dangers Of Low Blood Glucose
At some time, most people with diabetes experience the sweating and shakiness that occurs when blood glucose levels fall below 70 mg/dl a condition known as hypoglycemia. The average person with type 1 diabetes may experience symptoms of low blood glucose up to two times a week. However, not all are aware that these symptoms can rapidly progress to seizures, coma and even death if hypoglycemia is severe. Though hypoglycemia can be common and occur repeatedly in some people with diabetes, symptoms of low blood glucose should always be taken seriously.

Symptoms Of A Low Blood Sugar Level
A low blood sugar level can affect everyone differently. You’ll learn how it makes you feel, although your symptoms may change over time.
Early signs of a low blood sugar level include:
- a fast or pounding heartbeat
- becoming easily irritated, tearful, anxious or moody
If a low blood sugar level is not treated, you may get other symptoms, such as:
- unusual behaviour, slurred speech or clumsiness
- seizures or fits
- collapsing or passing out
A low blood sugar level, or hypo, can also happen while you’re sleeping. This may cause you to wake up during the night or cause headaches, tiredness or damp sheets in the morning.
How Do You Treat Low Blood Sugar
A popular method for treating low blood sugar is to follow the Rule of 15. This is when a person experiencing low blood glucose eats 15 grams of carbohydrates, then waits for 15 minutes for their glucose to rise.
These 15 minutes can feel impossibly long, but its important to be as patient as possible to see if the initial intake of 15 grams of carbohydrates is working.
If glucose levels have not come up in the initial 15 minutes, the person should consume 15 more grams of carbohydrates and repeat the process.
If they are using a continuous glucose monitoring system, they should remember that it can take a few more minutes for the interstitial glucose to reflect the glucose absorbed from the gastrointestinal tract. It is best to check a fingerstick in 15 minutes to confirm that glucose is rising, as the rise in glucose could be delayed on CGM.
When in doubt, use a fingerstick to verify glucose levels especially if the symptoms dont match the CGM values.
Another way to treat low blood sugar is by using glucagon.

Preventing A Low Blood Sugar Level
If you have diabetes, you can reduce your chance of getting a low blood sugar level if you:
- Check your blood sugar level regularly and be aware of the symptoms of a low blood sugar level so you can treat it quickly.
- Use a continuous glucose monitor or flash monitor to see how your blood sugar levels are changing. Ask your diabetes care team about getting a monitor if you do not already have one.
- Always carry a sugary snack or drink with you, such as glucose tablets, a carton of fruit juice or some sweets. If you have a glucagon injection kit, always keep it with you.
- Do not skip meals.
- Be careful when drinking alcohol. Do not drink large amounts, check your blood sugar level regularly, and eat a carbohydrate snack afterwards.
- Be careful when exercising eating a carbohydrate snack before exercise can help to reduce the risk of a hypo. If you take some types of diabetes medicine, your doctor may recommend you take a lower dose before or after doing intense exercise.
- Have a carbohydrate snack, such as toast, if your blood sugar level drops too low while you’re asleep .
If you keep getting a low blood sugar level, talk to your diabetes care team about things you can do to help prevent it.
What Causes Low Blood Sugar A Remedial Guide
Blood sugar, or glucose, is the primary type of sugar found in your blood. The main source of sugars is a carbohydrate available in various foods. Generally, 80 to 99 mg/dl of blood sugar before a meal and 80 to 140 mg/dl after a meal are considered normal.
When blood sugar falls below the normal level, it results in hypoglycemia. This medical condition of low blood sugar can be challenging to diagnose early and manage. However, treatments are available to prevent hypoglycemia from progressing to an emergency.
Despite the common belief that low blood sugar is most commonly related to diabetes, people without diabetes can also experience episodes of hypoglycemia. Read more about the different causes of low blood sugar.

Low Blood Sugar Levels In Diabetes
People with diabetes can have low blood sugar levels because of the medicines they have to take to manage their diabetes. They may need a hormone called or diabetes pills to help their bodies use the sugar in their blood.
These medicines help take the sugar out of the blood and get it into the body’s cells, which makes the blood sugar level go down. But sometimes it’s a tricky balancing act and blood sugar levels can get too low.
People with diabetes need to keep their blood sugars from getting too highor too low. Keeping blood sugar levels in a healthy range means balancing when and what they eat, and when they exercise with when they take medicines.
What Is Low Blood Sugar
When the body absorbs food, blood sugar goes up and the pancreas secretes the hormone insulin so the food can be digested and converted into energy. However, if blood sugar drops too low, the body tells the liver to release a type of sugar called glycogen, which is designed to help restore balance when the body perceives a problem.
For people who arent living with diabetes, this release of glycogen from the liver naturally occurs without them ever realizing it. However, for people living with diabetes, the bodys response to hypoglycemia is impaired.
Eventually, and sometimes on delay, the glycogen will release from the liver and the person with diabetes will experience hyperglycemia or high blood sugar. This rebound impact of hypoglycemia, followed by hyperglycemia, doesnt feel very good and can make the person feel tired and worn out.It is not just high blood sugars and lack of insulin that people with type 1 diabetes have to deal with, said Dr. Jordan Pinsker, Vice President and Medical Director for Tandem Diabetes Care who is also a leading endocrinologist. Many people do not realize that even shortly after the diagnosis of type 1 diabetes is made, the cell signaling that the body uses to raise blood sugar is also not always working correctly. This makes it even harder to respond to a low blood sugar.
