Avoidance of hypoglycemia for several weeks may lead to improved hypoglycemia awareness. Hypoglycemia should not be viewed as an insurmountable barrier, but rather as an opportunity to potentially improve a recommended medication strategy, improve on daily diabetes care practices, or uncover other medical diagnoses that may be contributing to the development of hypoglycemia.

How can HCPs assist individuals with diabetes in identifying potential risk factors for the development of hypoglycemia or identifying the causes of hypoglycemia events? The cause may seem obvious: either the diabetes medication, likely insulin, did not match the amount of food ingested, or the level of exercise a patient performed was too much for the amount of food ingested and the amount of medication taken.

But often, teasing out the exact triggers can be a challenge. Table 1 provides a checklist of potential causes of hypoglycemia. HCPs may need to think like a crime scene investigator to uncover the causes and contributing factors that have led to a hypoglycemic event.

Allowing individuals with diabetes and their family to tell their story about a hypoglycemic event may allow HCPs to uncover a need not only for medication changes, but also for changes in patients' behavioral responses to hypoglycemia. Empowering individuals to have more control over such situations will also help reduce the anxiety and fear often associated with hypoglycemia.

Probing patients with pertinent questions will help create an accurate understanding of the context of reported hypoglycemia. This can also reduce misunderstandings between patients and providers and provide education opportunities about skills or concepts that may seem basic to providers but can be challenging for patients.

When patients report that they have been experiencing low blood glucose, it is important to define hypoglycemia together. What do patients consider to be a low blood glucose level? Is this based solely on feelings or have they been able to actually check their blood glucose at the moment of symptoms?

If self-monitoring of blood glucose SMBG records are available, at what point or level of blood glucose do individuals start to experience symptoms of hypoglycemia?

People with consistently high blood glucose levels will feel hypoglycemic at blood glucose levels higher than the normal range, whereas those with tight glycemic control may feel hypoglycemic at lower levels.

Discussing these concepts with patients provides practical motivation and support for the role of SMBG in medication adjustment and safety. Another area worthy of inquiry is patients' actions leading up to hypoglycemic events. It may seem obvious that changes in food choices, physical activity, or medication can produce hypoglycemia, but letting patients verbalize their patterns or changes in patterns can allow them to discover this for themselves.

Eating a smaller meal or one containing less carbohydrate than normal may result in a low postprandial blood glucose level. If changes in food choices lead to hypoglycemic events, patients likely did not do this on purpose. Have they been less hungry lately, or are they trying to lose weight?

Has there been a change in their oral health? Many individuals do not understand the complexity of factors affecting postprandial glucose levels or are not able to consistently identify a low-carbohydrate or high-carbohydrate meal or to accurately estimate the number of calories in their meals.

For patients who are doing basic carbohydrate counting, explore the potential impact of the presence or absence of protein and fat in meals. These individuals may not recognize or may easily forget the role of protein and fat because they are concentrating more closely on carbohydrates.

For patients who are counting calories or using some overall means of portion control, explore the impact of significant changes in carbohydrate content and assess their ability to identify foods that are rich in carbohydrates.

These individuals may not understand the importance of carbohydrate budgeting. In these discussions, providers may find patients to be at a point of readiness to be referred to a registered dietitian or certified diabetes educator for more nutrition education.

Changes in physical activity that can lead to hypoglycemia can include more than just intentional exercise. Particularly for people who are usually sedentary, an increase in overall energy and stamina that leads to doing more errands, gardening, or housework than normal may result in hypoglycemia.

In contrast, athletes with diabetes who have temporary periods of two-a-day practices might need help learning how to adjust their medication to deal with the increase in insulin sensitivity and glucose uptake that results from increased exercise.

Asking open-ended questions about the timing and dosing of medication or asking patients to demonstrate or describe their injection technique also may reveal potential causes of hypoglycemia. Finally, it is important to ask exactly how patients treat low blood glucose. This question often reveals a tendency to consume more than the recommended 15—20 g of carbohydrate or may uncover a misunderstanding of what types of foods and substances will most quickly raise the blood glucose level.

Table 2 reviews the recommended treatment guidelines for hypoglycemia. Discussing patients' knowledge of food choices, physical activity, and medication can help prevent future hypoglycemia and allow providers to best determine any necessary changes in medication and identify education needs.

Lipohypertrophy is a buildup of fat at the injection site. Injecting insulin into lipohypertrophy usually causes impaired absorption of insulin. However, injecting into sites of lipohypertrophy can result in erratic and unexplained fluctuations in blood glucose.

When advising patients to rotate to new injection sites, HCPs should note the need for caution. Because insulin injected into a fresh site likely will be absorbed more efficiently, doses may need to be decreased. Regular rotation of insulin injection sites may prevent lipohypertrophy from occurring.

Keep in mind that some patients, especially children, may be hesitant to inject in areas other than one with lipohypertrophy because they report that area is less sensitive to injections.

Many alcohol-containing drinks contain carbohydrate and can cause initial hyperglycemia. However, alcohol also inhibits gluconeogenesis, which becomes the main source of endogenous glucose about 8 hours after a meal.

Therefore, there is increased risk of hypoglycemia the morning after significant alcohol intake if there has not been food intake. Alcohol consumption can also interfere with the ability to feel hypoglycemia symptoms. For patients whose blood glucose is well controlled, the ADA guidelines for alcohol intake suggest a maximum of one to two drinks per day, consumed with food.

Close monitoring of blood glucose for the next 10—20 hours may be beneficial. Insulin and sulfonylurea clearance is decreased with impaired hepatic or renal function. Decreasing the dosages of some anti-hyperglycemic medications and avoiding others may be necessary.

Of the oral agents, sulfonylureas are more likely to cause hypoglycemia. Glimepiride may be a safer choice than glyburide or glipizide in elderly patients and those with renal insufficiency because it is completely metabolized by the liver; cytochrome P reduces it to essentially inactive metabolites that are eliminated renally and fecally.

As kidney function declines, exogenous insulin has a longer duration and is more unpredictable in its action, and the contribution of glucose from the kidney through gluconeogensis is reduced. Patients who have had diabetes for many years or who have had poor control are at risk for autonomic neuropathy, including gastroparesis, or slow gastric emptying.

It is thought that delayed food absorption increases the risk of hypoglycemia, although evidence is lacking. Intercurrent gastrointestinal problems such as gastroenteritis or celiac disease can also be causes of altered food absorption.

Medications such as metoclopramide or erythromycin are used to increase gastric emptying time. Giving mealtime insulin after meals or using an extended bolus on an insulin pump may also help to prevent potential hypoglycemia related to delayed gastric emptying.

Hypothyroidism slows the absorption of glucose through the gastrointestinal tract, reduces peripheral tissue glucose uptake, and decreases gluconeogenesis.

For people with diabetes, this can cause increased episodes of hypoglycemia. Measuring the level of thyroid-stimulating hormone is the most accurate method of evaluating primary hypothyroidism.

If you add in lows Hypoglycekic symptoms Hypogoycemic the ones that happen overnight, the number would likely be higher. Too Hypoglycemkc insulin is a Hypoglyceimc cause of low blood glucose. Insulin pumps may also reduce the risk for low blood glucose.

Accidentally injecting the wrong insulin type, too much insulin, or injecting directly into the muscle instead of just under the skincan cause low blood glucose. Exercise has many benefits. The tricky thing for people with type 1 diabetes is that it can lower blood glucose in both the short and long-term.

Nearly half of children in a type 1 diabetes study who exercised an hour during the day experienced a low blood glucose reaction overnight. The intensity, duration, and timing of exercise can all affect the risk for going low. Many people with diabetes, particularly those who use insulin, should have a medical ID with them at all times.

In the event of a severe hypoglycemic episode, a car accident or other emergency, the medical ID can provide critical information about the person's health status, such as the fact that they have diabetes, whether or not they use insulin, whether they have any allergies, etc.

Emergency medical personnel are trained to look for a medical ID when they are caring for someone who can't speak for themselves. Medical IDs are usually worn as a bracelet or a necklace. Traditional IDs are etched with basic, key health information about the person, and some IDs now include compact USB drives that can carry a person's full medical record for use in an emergency.

As unpleasant as they may be, the symptoms of low blood glucose are useful. These symptoms tell you that you your blood glucose is low and you need to take action to bring it back into a safe range. But, many people have blood glucose readings below this level and feel no symptoms.

This is called hypoglycemia unawareness. Hypoglycemia unawareness puts the person at increased risk for severe low blood glucose reactions when they need someone to help them recover. People with hypoglycemia unawareness are also less likely to be awakened from sleep when hypoglycemia occurs at night.

People with hypoglycemia unawareness need to take extra care to check blood glucose frequently. This is especially important prior to and during critical tasks such as driving.

A continuous glucose monitor CGM can sound an alarm when blood glucose levels are low or start to fall. This can be a big help for people with hypoglycemia unawareness. If you think you have hypoglycemia unawareness, speak with your health care provider. This helps your body re-learn how to react to low blood glucose levels.

This may mean increasing your target blood glucose level a new target that needs to be worked out with your diabetes care team. It may even result in a higher A1C level, but regaining the ability to feel symptoms of lows is worth the temporary rise in blood glucose levels.

This can happen when your blood glucose levels are very high and start to go down quickly. If this is happening, discuss treatment with your diabetes care team. Your best bet is to practice good diabetes management and learn to detect hypoglycemia so you can treat it early—before 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.

Together, you can review all your data to figure out the cause of the lows. The more information you can give your health care provider, the better they can work with you to understand what's causing the lows.

Your provider may be able to help prevent low blood glucose by adjusting the timing of insulin dosing, exercise, and meals or snacks. Changing insulin doses or the types of food you eat may also do the trick. Breadcrumb Home Life with Diabetes Get the Right Care for You Hypoglycemia Low Blood Glucose.

Low blood glucose may also be referred to as an insulin reaction, or insulin shock. Signs and symptoms of low blood glucose happen quickly Each person's reaction to low blood glucose is different.

Treatment—The " Rule" The rule—have 15 grams of carbohydrate to raise your blood glucose and check it after 15 minutes. Note: Young children usually need less than 15 grams of carbs to fix a low blood glucose level: Infants may need 6 grams, toddlers may need 8 grams, and small children may need 10 grams.

This needs to be individualized for the patient, so discuss the amount needed with your diabetes team. When treating a low, the choice of carbohydrate source is important. Complex carbohydrates, or foods that contain fats along with carbs like chocolate can slow the absorption of glucose and should not be used to treat an emergency low.

Treating severe hypoglycemia Glucagon is a hormone produced in the pancreas that stimulates your liver to release stored glucose into your bloodstream when your blood glucose levels are too low.

Steps for treating a person with symptoms keeping them from being able to treat themselves. If the glucagon is injectable, inject it into the buttock, arm, or thigh, following the instructions in the kit. If your glucagon is inhalable, follow the instructions on the package to administer it into the nostril.

When the person regains consciousness usually in 5—15 minutesthey may experience nausea and vomiting. Do NOT: Inject insulin it will lower the person's blood glucose even more Provide food or fluids they can choke Causes of low blood glucose Low blood glucose is common for people with type 1 diabetes and can occur in people with type 2 diabetes taking insulin or certain medications.

Insulin Too much insulin is a definite cause of low blood glucose. Food What you eat can cause low blood glucose, including: Not enough carbohydrates. Eating foods with less carbohydrate than usual without reducing the amount of insulin taken.

Timing of insulin based on whether your carbs are from liquids versus solids can affect blood glucose levels. Liquids are absorbed much faster than solids, so timing the insulin dose to the absorption of glucose from foods can be tricky.

The composition of the meal—how much fat, protein, and fiber are present—can also affect the absorption of carbohydrates. Physical activity Exercise has many benefits. Medical IDs Many people with diabetes, particularly those who use insulin, should have a medical ID with them at all times.

Hypoglycemia unawareness occurs more frequently in those who: Frequently have low blood glucose episodes which can cause you to stop sensing the early warning signs of hypoglycemia. Have had diabetes for a long time.

Tightly manage their diabetes which increases your chances of having low blood glucose reactions. How can I prevent low blood glucose? If you can, check often!

Check before and after meals. Check before bed. After intense exercise, also check in the middle of the night. Check more if things around you change such as, a new insulin routine, a different work schedule, an increase in physical activity, or travel across time zones.

Low Blood Sugar (Hypoglycemia) | Diabetes | CDC	By this point you are unlikely to be able to treat the hypo yourself but may require assistance from others, or could become unconscious. There are various reasons. In someone with long-standing type 1 diabetes, there may be a degree of autonomic neuropathy, or abnormal nerve responses, impeding the normal early warning system the body triggers to alert you to a hypo. The good news is that it may be possible to restore early warning symptoms. By avoiding low BGLs, the early warning system can be woken up and returned to duty. This would be best addressed with the support of an experienced diabetes management team. For more information contact the NDSS Helpline on and ask to speak with a Credentialed Diabetes Educator. Who is at risk of HU? HU typically occurs in people who: have had type 1 diabetes for a long time, are managing BGLs very tightly sitting at the lower end of target range more than upper end , are having frequent hypos, have type 1 or type 2 diabetes and declining cognitive function, where they may are no longer capable of realising they have a low BGL.

However, it's important to talk to your health care provider and not just intentionally keep your blood glucose high because of this. High blood glucose levels can lead to serious long-term complications. See "Patient education: Preventing complications from diabetes Beyond the Basics ". The treatment of low blood glucose depends on whether you have symptoms and how severe the symptoms are. No symptoms — Your health care provider will talk to you about what to do if you check your blood glucose and it is low, but you have no noticeable symptoms. They might recommend checking your levels again after a short time, avoiding activities like driving, or eating something with carbohydrates. Early symptoms — If you have early symptoms of low blood glucose, you should check your level as soon as possible. However, if your monitoring equipment is not readily available, you can go ahead and give yourself treatment. It's important to treat low blood glucose as soon as possible. To treat low blood glucose, eat 15 grams of fast-acting carbohydrate. This amount of food is usually enough to raise your blood glucose into a safe range without causing it to get too high. Avoid foods that contain fat like candy bars or protein such as cheese initially, since they slow down your body's ability to absorb glucose. Check your blood glucose again after 15 minutes and repeat treatment if your level is still low. Monitor your blood glucose levels more frequently for the next few hours to ensure your blood glucose levels are not low. Severe symptoms — If your blood glucose is very low, you may pass out or become too disoriented to eat. A close friend or relative should be trained to recognize severe low blood glucose and treat it quickly. Dealing with a loved one who is pale, sweaty, acting bizarrely, or passed out and convulsing can be scary. A dose of glucagon stops these symptoms quickly if they are caused by hypoglycemia. Glucagon is a hormone that raises blood glucose levels. Glucagon is available in emergency kits as an injection or a nasal spray , which can be bought with a prescription in a pharmacy. Directions are included in each kit; a roommate, partner, parent, or friend should learn how to give glucagon before an emergency occurs. It is important that your glucagon kit is easy to locate, is not expired, and that the friend or relative is able to stay calm. You should refill the kit when the expiration date approaches, although using an expired kit is unlikely to cause harm. This releases the powder into the person's nostril without requiring them to inhale or do anything else. If you have to give another person glucagon, turn them onto their side afterwards. This prevents choking if they vomit, which sometimes happens. Low blood glucose symptoms should resolve within 10 to 15 minutes after a dose of glucagon, although nausea and vomiting may follow 60 to 90 minutes later. As soon as the person is awake and able to swallow, offer a fast-acting carbohydrate such as glucose tablets or juice. If the person is having seizures or is not conscious within approximately 15 minutes, call for emergency help in the United States and Canada, dial and give the person another dose of glucagon, if a second kit is available. FOLLOW-UP CARE. After your blood glucose level normalizes and your symptoms are gone, you can usually resume your normal activities. If you required glucagon, you should call your health care provider right away. They can help you to determine how and why you developed severely low blood glucose and can suggest adjustments to prevent future reactions. In the first 48 to 72 hours after a low blood glucose episode, you may have difficulty recognizing the symptoms of low blood glucose. In addition, your body's ability to counteract low blood glucose levels is decreased. Check your blood glucose level before you eat, exercise, or drive to avoid another low blood glucose episode. WHEN TO SEEK HELP. A family member or friend should take you to the hospital or call for emergency assistance immediately if you:. Once in a hospital or ambulance, you will be given treatment intravenously by IV to raise your blood glucose level immediately. If you require emergency care, you may be observed in the emergency department for a few hours before being released. In this situation, you will need someone else to drive you home. Your health care provider is the best source of information for questions and concerns related to your medical problem. This article will be updated as needed on our website www.

About diabetes	Slowed counter-regulatory hormones, erratic food intake, and slowed unawarenes absorption Ketosis and Metabolism Hyoglycemic adults unawarehess higher Herbal tea for detoxification of hypoglycemia. Short-term risks of hypoglycemia Hypoglycemic unawareness education the dangerous situations Hypoglycemic unawareness education can arise while an individual is hypoglycemic, whether at home or at work e. Avoidance of hypoglycemia with adjustment of doses of insulin aiming for higher fasting, preprandial, and bedtime BG targets. This is especially true before and during critical tasks, such as driving. It is thought that delayed food absorption increases the risk of hypoglycemia, although evidence is lacking. Using these therapies, hypoglycemia can be avoided leading to improve sympathoadrenal responses of hypoglycemia and awareness of hypoglycemia.

Amit Gupta : Hypoglycemia Unawareness and Management Journal of Medical Case Unawarrness Hypoglycemic unawareness education 16 unawarenses, Article Hypoglyycemic Cite this oxidative stress and gut health. Metrics details. Hypoglycemia is a fairly common Hypoglycmeic in Ketosis and Metabolism patients, Hypoglycemic unawareness education in those on insulin therapy. Hypoglycemia symptoms are classified Hypoglycemiv two edhcation Ketosis and Metabolism and neuroglycopenic symptoms. If a person develops neuroglycopenic symptoms before the appearance of autonomic symptoms or is asymptomatic until blood sugar levels are very low, the patient will develop hypoglycemic unawareness HU. A year-old Iranian woman with HU presented with a severe hypoglycemic episode. This episode was characterized by loss of consciousness and focal neural deficits, which were unusual symptoms in the patient, who was a medical intern with type 1 diabetes and currently being treated with regular and NPH insulin.
