Insulin Questions: How do I treat my low blood sugar?

Mild hypoglycemia and hyperglycemia are usually treatable at home.

If you have mild hypoglycemia, consuming a small amount of glucose can quickly raise your blood sugar.

If you skipped a dose of medication and have symptoms of mild hyperglycemia, taking your insulin or diabetes medication can help stabilize your blood sugar level.

Hypoglycemia is an emergency if you experience confusion, blurry vision, or seizures.

Hyperglycemia is an emergency if you have:

  • shortness of breath

What Are The Symptoms Of Low Blood Sugar

Its important to recognize the signs and symptoms of blood sugar dropping quickly.

These symptoms could include:

  • An accelerated heartbeat

When someone experiences a low blood sugar , their brain tells their body they need to eat. The tendency to eat until we feel well may fix the low blood sugar, but it may also be too much of a sugar intake that will require additional insulin later. This is why its important to be aware of carbohydrate intake.

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
  • 2 tablespoons of raisins
  • 1 tube of glucose gel or 3 to 4 glucose tablets
  • Check your blood sugar level 15 minutes later. If the level is still less than 100 mg/dL, eat another 15 grams of carbohydrate. When the level returns to 100 mg/dL, eat a snack or meal that contains carbohydrates. This will help prevent another drop in blood sugar.
  • Teach people close to you how to use your glucagon kit. Your blood sugar may be too low for you to be awake. People need to know when and how to use your kit.

    Low Blood Sugar: Best Bites When Youre On The Go

    Despite your best planning, you might find yourself experiencing low blood sugar when youre out and about, with no glucose tablets in reach. Here are tips to keep in mind:

    Best bites at work Smart foods to keep in a drawer at work are 4-ounce cans or cartons of any type of 100 percent juice hard candy like peppermints or Life Savers and small boxes of raisins the ones that contain about 2 tablespoons, says Hope Warshaw, RD, a certified diabetes educator and author of Diabetes Meal Planning Made Easy.

    If you dont have these items on hand, head to the nearest vending machine for any snack containing carbohydrates or sugary candy but skip the chocolate. We do not recommend using chocolate as a treatment for hypoglycemia, despite what you might have read, says OConnor. She explains that the fat in chocolate slows down how fast the sugar and carbohydrates in the candy can get into the bloodstream.

    If youre choosing foods to help treat hypoglycemia, you should also pay attention to where they fall on the glycemic index, or GI. The higher a food ranks on the GI, the more quickly your body breaks it down into sugar. Life Savers have a GI of 70, while raisins have a GI around 60.

    How Does Hypoglycemia Occur Without Diabetes

    Hypoglycemia usually happens to people living with diabetes, but its possible to have low blood sugar without diabetes.

    Blood sugar, or glucose, is what your body uses for energy. After eating a meal or drinking a beverage, the hormone insulin allows sugar to enter your bodys cells, where its used for energy. Insulin is a hormone produced by your pancreas.

    Hypoglycemia occurs when you have too much insulin in your bloodstream. This might happen if you dont eat for several hours, such as 8 hours or more. A drop in blood sugar means there isnt enough glucose in your bloodstream to fuel your brain and body.

    Low blood sugar without diabetes can also occur if you take a medication that lowers your blood sugar. These include pain relievers like:

    • some antibiotics

    Other causes of low blood sugar without diabetes include binge-drinking and increased physical activity.

    Plus, some medical conditions can increase the amount of insulin your pancreas produces. These include a pancreatic tumor, adrenal gland disorders, and hepatitis.

    You could also experience low blood sugar if you have prediabetes, or if you eat a lot of refined carbohydrates, such as white bread, pasta, and pastries.

    No Symptoms Be Alarmed

    Surprisingly, the most dangerous episodes of hypoglycemia occur with little or no warning. When low blood glucose occurs on a regular basis, the body can become used to the warning signs and the person may stop noticing symptoms. This is a particularly dangerous condition known as hypoglycemic unawareness. People with this condition might not realize they have low blood glucose until it’s dangerously low seizures and coma are sometimes the first indication of a problem. The good news is that this condition can often be reversed allowing people to once again notice the signs of low blood glucose if hypoglycemia is avoided for a few weeks through careful monitoring of blood glucose.

Many people experience blood sugars much lower than this without concern but for someone on , it can be quite dangerous to keep your blood sugar that low, especially if the person doesnt experience symptoms of low blood sugar.

If you can do that safely, without hypoglycemia, then you are well managed! If there are reasons your provider has counseled against this guideline, educate yourself about the reasons and follow their guidance.

    How To Test Your Blood Sugar At Home

    To perform a blood sugar test, you will need to prick your finger with a lancet . Youll put a small sample of blood from this onto a strip inserted into the blood glucose meter.

    Before you test your blood sugar at home, its important to find out from your doctor what a healthy blood sugar range is for you. Your doctor will determine this range based on factors such as:

    • the type of diabetes you have
    • how long youve had diabetes
    • whether you have any other chronic health conditions

    If you dont have a blood sugar testing machine on hand and are experiencing signs or symptoms of low blood sugar with diabetes, your symptoms may be enough to diagnose low blood sugar.

    Manage Your Carb Intake

    Your carb intake strongly influences your blood sugar levels .

    Your body breaks carbs down into sugars, mainly glucose. Then, insulin helps your body use and store it for energy.

    When you eat too many carbs or have insulin-function problems, this process fails, and blood glucose levels can rise.

    Thats why the American Diabetes Association recommends that people with diabetes manage their carb intake by counting carbs and being aware of how many they need .

    Some studies find that this can help you plan your meals appropriately, further improving blood sugar management (

    Foods that are high in fiber include:

    The recommended daily intake of fiber is about 25 grams for women and 35 grams for men. Thats about 14 grams for every 1,000 calories .


    Eating plenty of fiber can aid blood sugar management. Soluble dietary fiber appears to be more effective than insoluble fiber for this purpose.

    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.
