How Can I Prevent Hypoglycemic Episodes

The key to preventing hypoglycemic events is managing diabetes:

  • Follow your healthcare providers instructions about food and exercise.
  • Track your blood sugar regularly, including before and after meals, before and after exercise and before bed.
  • Take all your medications exactly as prescribed.
  • When you do have a hypoglycemic event, write it down. Include details such as the time, what you ate recently, whether you exercised, the symptoms and your glucose level.

When Your Blood Sugar Gets Low

Check your blood sugar whenever you have symptoms of low blood sugar. If your blood sugar is below 70 mg/dL, treat yourself right away.

1. Eat something that has about 15 grams of carbohydrates. Examples are:

  • 3 glucose tablets
  • One half cup of fruit juice or regular, non-diet soda
  • 5 or 6 hard candies
  • 1 tablespoon or 15 mL of sugar, plain or dissolved in water
  • 1 tbsp of honey or syrup

2. Wait about 15 minutes before eating any more. Be careful not to eat too much. This can cause high blood sugar and weight gain.

3. Check your blood sugar again.

4. If you do not feel better in 15 minutes and your blood sugar is still lower than 70 mg/dL , eat another snack with 15 g of carbohydrates.

You may need to eat a snack with carbohydrates and protein if your blood sugar is in a safer range — over 70 mg/dL — and your next meal is more than an hour away.

Ask your provider how to manage this situation. If these steps for raising your blood sugar do not work, call your doctor right away.

What Should I Do If This Happens

People and their partners or roommates should learn to recognize the signs of nighttime hypoglycemia. Be prepared! Ask your doctor for an emergency glucagon kit.

DO NOT PUT ANYTHING INTO A PERSON’S MOUTH IF THEY ARE ASLEEP OR CANNOT SIT UP.

  • If the person cannot be woken: If there is no emergency glucagon kit, call 911. If the person has a glucagon kit, the partner or roommate should follow the instructions to fill the syringe and inject the medicine. Once fully awake, he/she should eat a meal and check their blood glucose every few hours using a home test kit. After giving the injection, the persons doctor should be notified.

  • If the person can be woken up and sit without support: They should be given a fast-acting glucose source.

    Why Is Insulin A Factor In Low Blood Sugar

    Insulin is a hormone that allows glucose to enter the cells from the blood which lowers blood glucose/sugar levels. In people without diabetes, the pancreas knows how much insulin it needs to release in order to lower blood sugar.

    But for people with diabetes when deciding themselves how much insulin is needed this is less straightforward. A person can have a good understanding of what the body might need, through calculations.

    But there is a great deal to consider, which can be overwhelming sometimes. As a result, errors in calculating insulin can and do occur. Thats why diabetes applications like Hedia, wink, wink exist.

    Hedias insulin calculator will take away the worries of figuring it out for yourself. You dont even need to enter your blood sugar readings yourself: they can be added wirelessly with certain NFC or Bluetooth glucose meters to Hedia!

    Start to take those worries away by downloading Hedia from the App Store or !

    This should all lead to more accurate results. In turn, this means that a rapid drop in blood sugar should be less likely.

    But its not only about human errors or miscalculations. Its also about the nature of insulin medication.

    Specifically, many people with diabetes nowadays use rapid-acting insulin at mealtimes in order to counteract the rapid rise in blood sugar after eating.

    Don’t Miss: What Is High Glucose Levels

    Rebound Hypoglycemia After Eating

    If sugar comes from the food you eat, why would blood sugar be low after eating? It may be due to a phenomenon called reactive hypoglycemia. This refers to low levels of blood glucose that react to high levels. According to Mayo Clinic, it can occur within 4 hours of eating a meal.

    Say breakfast includes pancakes, syrup, and fruit juice. The meal is full of carbs: starch in the pancakes, added sugar in the syrup, and natural sugar in the fruit juice. Those carbohydrates get absorbed fast.

    Blood sugar can skyrocket, especially in people who have prediabetes or diabetes. You may feel a sugar high, or burst of energy, within minutes to an hour of eating. Thenthe crash. The higher they fly, the harder they fall, is spot-on for blood sugar. If it went up, up, up, it will go down, down down, possibly below normal levels and into the range of hypoglycemia.

    The Effects Of Low Blood Sugar On Your Body

    I can

    Every cell in your body needs energy to function. The main source of energy might come as a surprise: Its sugar, also known as glucose. Blood sugar is essential to proper brain, heart, and digestive function. It even helps keep your skin and vision healthy.

    When your blood sugar levels fall below the normal range, its called hypoglycemia. There are many identifiable symptoms of low blood sugar, but the only way to know if you have low blood sugar is by taking a blood glucose test.

    Learn more about the symptoms of low blood sugar, as well as the long-term effects on the body.

    most common reasons for low blood sugar are some medications used to treat diabetes, such as insulin.

    In type 1 diabetes, the pancreas can no longer produce insulin. In type 2 diabetes, the pancreas doesnt make enough insulin, or your body cant use it properly. Too much insulin or oral diabetic medication can lower the blood sugar level, leading to hypoglycemia.

    However, contrary to popular belief, low blood sugar isnt exclusive to diabetes, though it is rare. It can also happen if your body makes more insulin than it should.

    Another possible cause of low blood sugar is drinking too much alcohol, especially over long periods of time. This can interfere with the livers ability to create a buildup of glucose and then release it into your bloodstream when you need it.

    Other causes include:
