What Is Hypoglycemia And Low Blood Sugar

Hypoglycaemia – How to Treat and Prevent Low Blood Sugar

Hypoglycemia is the state of having a blood glucose level that is too low to effectively fuel the bodys cells.

Glucose, which comes from carbohydrates found in foods, is a main source of energy for all of the cells of the body and, especially, the brain. While the body is quite good at extracting glucose from the foods we eat, it relies on a hormone called insulin to actually get the glucose inside the cells of specific organs: the liver, fat, and muscle.

We can think of insulin as holding the key to a cell without insulin, the glucose just remains in the blood, where its also known as blood sugar. During an episode of hypoglycemia, theres not enough glucose in the blood. The normal range is approximately 70 to 150 mg/dl .

Hypoglycemia is most common in newborns. In older children, its most often seen as a complication of insulin therapy for diabetes but can sometimes have other causes as well.

In the majority of cases, hypoglycemia is temporary, easily treated, and usually does not have serious consequences. There are several rare disorders in which hypoglycemia is recurrent and potentially life-threatening. However, with timely diagnosis and appropriate treatment, these can be effectively managed.

What To Eat When You Have Low Blood Sugar

When your blood sugar dips, it can leave you feeling hungry, shaky, and lightheaded. This can happen to anyone who hasnt eaten in several hours. When blood sugar drops below normal levels, its called hypoglycemia. In people with diabetes, hypoglycemia can be a life-threatening complication of diabetes medication, other health problems like infection, or inadequate caloric intake.

You can lower your chances of low blood sugarand treat it when it occurswith some simple steps.

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.

What Happens If Your Blood Sugar Is Too Low

If untreated, low blood glucose can quickly become an emergency. In cases of severe hypoglycemia, you may be unable to eat something to treat the low. That’s why your healthcare provider has probably recommended that you carry a glucagon kit. When given to you by another person, this injection of the hormone glucagon quickly stimulates your body to produce the glucose you need.1

Talk to your friends and family about what signs to look for and, if needed, how to use the glucagon kit in an emergency.

How Can I Prevent Low Blood Glucose

Symptoms Of Low And High Blood Sugar

Your best bet is to practice good diabetes management and learn to detect hypoglycemia so you can treat it earlybefore it gets worse.

Monitoring blood glucose, with either a meter or a CGM, is the tried and true method for preventing hypoglycemia. Studies consistently show that the more a person checks blood glucose, the lower his or her risk of hypoglycemia. This is because you can see when blood glucose levels are dropping and can treat it before it gets too low.

If you can, check often!

  • Check before and after meals.
  • Check before and after exercise .
  • Check before bed.
  • After intense exercise, also check in the middle of the night.

Treating Severely Low Blood Sugar

Blood sugar below 55 mg/dL is considered severely low. You wont be able to treat it using the 15-15 rule. You also may not be able to check your own blood sugar or treat it by yourself, depending on your symptoms. Make sure your family members, friends, and caregivers know your signs of low blood sugar so they can help treat it if needed.

Injectable glucagon is the best way to treat severely low blood sugar. A glucagon kit is available by prescription. Speak with your doctor to see if you should have a kit. Be sure to learn how and when to use it. Let family members and others close to you know where you keep the glucagon kit and make sure theyve been trained in how to use it too.

Its important to contact a doctor for emergency medical treatment immediately after receiving a glucagon injection. If a person faints due to severely low blood sugar, theyll usually wake up within 15 minutes after a glucagon injection. If they dont wake up within 15 minutes after the injection, they should receive one more dose. When the person is awake and able to swallow:

  • Feed the person a fast-acting source of sugar .
  • Then, have them eat a long-acting source of sugar .

Its also important that friends, family, co-workers, teachers, coaches, and other people you may be around often know how to test your blood sugar and treat severely low blood sugar before it happens.

If any of the following happens, your friend, relative, or helper should call 911:

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. Hypoglycemia that leads to extended, reduced brain function is the biggest concern, as this can lead to seizures and loss of basic bodily functions controlled by the brain, which can ultimately lead to death, explains Dr. Dyer.

If A Person Is Unconscious

What Is a Low Blood Sugar and What Can You Do About It

If a person loses consciousness because of severe hypoglycaemia, they need to be put into the recovery position and given an injection of the hormone glucagon . The injection will raise their blood glucose level.

The injection should be carried out by a friend or family member who knows what they’re doing, or by a trained healthcare professional.

You should dial 999 to request an ambulance if:

  • a glucagon injection kit isn’t available
  • there’s nobody available who’s trained to give the injection
  • the injection is ineffective after 10 minutes

Never try to put food or drink into the mouth of someone who’s unconscious as they could choke.

If you’re able to give a glucagon injection and the person regains consciousness, they should eat some longer-acting carbohydrate food, such as a few biscuits, a cereal bar or a sandwich.

You should continue to monitor the person for signs of recurring symptoms in case they need to be treated again.

Swollen Or Bleeding Gums Which Increase Your Infection Risk

Gum disease is a complication of diabetes, notes the National Institute of Diabetes and Digestive and Kidney Disease. It can also make diabetes harder to control, because the bodys response to infection is to release more glucose into the bloodstream, according to the ADA.

Your saliva contains glucose and the more it contains, the more there is to feed the bacteria that combine with food in your mouth to form plaque and cause gum disease. Symptoms can include red or inflamed gums at first. If they are unaddressed, they can progress to periodontitis, which can cause your gums to pull away from your teeth, the appearance of pus or ulcers, or even tooth loss, notes the Mayo Clinic. Get your blood sugar under control and see a dental professional to prevent damage to your gums and teeth.

    High Blood Sugar Causes

    LOW blood SUGAR in Diabetics (hypoglycemia). Everything you NEED to know!

    You may be thinking that hyperglycemia can happen just from eating a super-sugary food, but its not really as simple as that. Sure, eating a lot of sugar or carbs can elevate your blood sugar level, but thats typically when your pancreas kicks into gear and creates insulin to move that glucose into cells throughout the body.

    But when someone has diabetes, this finely tuned system gets thrown out of whack. In type 2 diabeteswhich accounts for 90% to 95% of diabetes in adults, according to the CDCthe body either cant make enough insulin or cant utilize insulin well, according to the NIDDK. If someone has prediabetes, their blood glucose will be higher than normal but not quite in the type 2 diabetes range yet, per the NIDDK. And in type 1 diabetes, the body does not make insulin or makes very little.

    In any case, the result is extra sugar hanging around the bloodstream, making you feel like total crap in the short term and putting your health at risk in the long term.

    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.

    • Signs and symptoms of low blood sugar. Your doctor may require you to fast, or abstain from drinking and eating for an extended period of time, so they can observe your low blood sugar signs and symptoms.
    • Documentation of low blood sugar when your signs and symptoms occur. Your doctor will order a blood test to analyze your blood sugar levels in a laboratory.
    • Disappearance of the signs and symptoms of low blood sugar. Your doctor will want to know whether the signs and symptoms go away when your blood sugar levels are raised.
