If they dont know how to give you the injection or if glucagon isnt available, they must call 911 and get you the help you need, Evans says. Low blood sugar thats sustained for a prolonged time can lead to irreversible brain damage, according to the University of Maryland Medical Center.

Wear an ID bracelet.;Evan suggests that everyone with;diabetes;should get a tattoo or wear a medical ID bracelet. The bracelet should say diabetes and whether youre on;insulin;or take other medications, the Joslin Diabetes Center in Boston recommends.

Talk to your doctor about your low blood sugar risk.;If you have frequent bouts of hypoglycemia, be sure to talk with your doctor. The solution may be as simple as changing how much or the kind of diabetes medicine you take. However,;never make any changes to your medication regimen;without your doctors approval.

How To Prevent Nocturnal Hypoglycemia

How Do I Quickly Bring Down My Blood Glucose (Lower High ...

Start by talking to your doctor about a bedtime blood sugar target. Ask about your risk for hypoglycemia and if you should get a glucagon kit. Dont miss dinner, exercise before bedtime, or drink alcohol at night. Have a sugar and protein snack before bedtime, like a wheat cracker with cheese.


If you have had symptoms of nocturnal hypoglycemia, work with your doctor on a prevention plan. This may include switching to a longer acting insulin that does not peak during sleep, or changing your insulin dose. You might be asked to set an alarm and check your blood sugar in the early morning for a while. ;For people at high risk for nocturnal hypoglycemia, a continuous glucose monitor may be the best solution.

How Can I Stop My Blood Sugar From Crashing

;Here are a few ways to avoid hypoglycemic episodes:

  • Get in the habit of self-monitoring your blood glucose. Keeping track of when your blood sugar drops can help you recognize aspects of your routine that may be contributing to your hypoglycemia. Dr. Klonoff recommends a continuous glucose monitor. Its the best tool for automatically checking your blood glucose levels around the clock, he says.
  • Change your meal plan. When, what, how much, and how often you eat all play a big part in your blood glucose levels. A dietitian can teach you about healthy, well-balanced food choices that will make it easier for you to maintain an acceptable blood sugar range.
  • Keep a stash of glucose tablets on hand. With your doctor’s recommendation, make sure you always have glucose tablets with you. You can stick them in your briefcase, purse, car, desk, school locker, etc. You may also want to keep snacks nearbyfor example, cheese or peanut butter crackers, although doctors suggest over-the-counter glucose tablets for more accurate dosage. Do not eat a healthy sugar-free candy bar during hypoglycemia, warns Dr. Klonoff. Its lack of sugar means that it will not raise your blood glucose level sufficiently when you want it to.
  • Certain drinks can help get your blood sugar up as well. Try 8 oz. of fruit juice, a soft drink , or a cup of milk.

Low Blood Glucose During Sleep

Your blood glucose level can drop while you sleep and stay low for several hours, causing serious problems.7 Symptoms of low blood glucose while you sleep can include


  • crying out or having nightmares
  • sweating enough to make your pajamas or sheets damp
  • feeling tired, irritable, or confused after waking up

What Extreme Conditions Can Occur If Hypoglycemia Is Left Untreated

Although severe episodes which can trigger potentially life-threatening comas are rare, they require immediate emergency room care, so its best to make sure you are tracking your blood sugar so that you never have to worry about getting to that point. A drop in blood sugar means less fuel for your brain, so its critical for your body to receive enough glucose.

What Is Low Blood Sugar And Why Is It Scary

What It Feels Like to Have a Low Blood Sugar

Low blood sugar can feel different for different people, both when it comes to when we feel low and how the symptoms manifest.

In a non-diabetic body, blood sugar levels rarely dip below 70 mg/dL, but if you manage your diabetes with insulin and if too much insulin is present in the body, blood sugars start to drop below normal levels.


Without enough glucose in your bloodstream, your brain and entire body will struggle to function and most people will start feeling the symptoms of low blood sugar.

If not treated with glucose, blood sugar can continue to drop, which can lead to a severe low blood sugar. A severe low blood sugar is defined as a situation where your blood sugar is so low that you need help from someone else to get your blood sugar back into a safe range.

    What Can Happen When We Dont Prepare For A Low Blood Sugar

    The week after, Paloma and her friend were on the road again. This time she didnt bring Gvoke and as she was trending low during the trip, she ate all of her low snacks before they arrived at their hotel.

    That night, she woke up and checked her CGM to find that her blood sugar had dropped to 40 mg/dL , and thats when her low symptoms intensified, and she started feeling poorly. But she was out of snacks and didnt have her glucagon with her, so there was no way of treating the low.


    Her friend ran to the vending machine in the hallway, but it was malfunctioning. As time was ticking, her friend ended up punching through the glass of the machine to get to the snacks.

    At this point, they were both panicking and once her friend returned with the snacks, Paloma ate as much as she could. This experience left them both emotionally drained and she had to fight resistant high blood sugars throughout the following day.

    • Are injecting your insulin the right way
    • Need a different type of needle
    • Should change how much insulin you take
    • Should change the kind of insulin you take

    DO NOT make any changes without talking to your doctor or nurse first.


    Sometimes hypoglycemia can be due to taking the wrong medicines. Check your medicines with your pharmacist.

    Prevention Of Low Blood Sugar

    Do not skip or delay meals. If your diet plan includes snacks, make sure to take these.

    Measure insulin dosage carefully and inject it properly. If you cannot see well, a family member or a visiting nurse can prepare your insulin injections for you.

    Take only the prescribed amount of insulin or oral medication for diabetes that your doctor has ordered.

    Keep exercise consistent from day to day. Eat a snack or reduce your insulin prior to unusual exercise.


    If you are taking insulin, notify your doctor if you have low blood sugars four or more times per week or if you have a severe low blood sugar. Severe low blood sugars are those less than 40 mg., those requiring help from another person, or those which cause you to have a convulsion or become unconscious.

    If you are taking oral medication for your diabetes notify your doctor or nurse if blood sugars are running less than 80 mg. or if you have a severe low blood sugar.

    • binge drinking or heavy alcohol consumption
    • liver, heart, or kidney disease
    • tumors that affect the pancreas
    • low hormone levels
    • certain medications, such as salicylates or sulfa

    Causes of reactive hypoglycemia include:

    • a person with prediabetes
    • enzyme deficiency
    • stomach surgery

    Signs Of High Blood Sugar

    Someone who has been diagnosed with diabetes will be familiar with how it feels to have hyperglycemia. But for the millions of people who have diabetes or prediabetes and are unaware of it, knowing the signs of high blood sugar could prompt them to seek care and get a diagnosis as soon as possible.

    While type 1 diabetes symptoms can come on suddenly and severely, its important to note that type 2 diabetes symptoms can creep up gradually and be so mild that theyre not noticeable, the NIDDK explains. And most people with prediabetes actually have no symptoms, per the NIDDK. So its extremely important to get screened if you have risk factors, like having a family history, being overweight, or being over age 45, the NIDDK says.

    Still, there are many potential signs of high blood sugar in the short and long term that it doesnt hurt to be conscious of, especially if you are at elevated risk.

    Early on, hyperglycemia can make you feel off in a variety of ways:
