Hypoglycemic unawareness causes and symptoms -
Another suggestion was to switch human insulin to the analog type of insulin. Hypoglycemia is a fairly common complication in diabetic patients receiving oral or insulin therapy. However, in a subset of patients who are unaware of hypoglycemia for a variety of reasons, these warning signs do not exist, resulting in severe and life-threatening hypoglycemic episodes.
As a result, patients who have multiple episodes of HU are advised to raise their blood sugar control threshold for at least 2 weeks and to wear at all times a bracelet or label indicating their medical condition.
In addition, in these patients, the use of CGM equipped with alarms in the occurrence of severely low blood sugar can be a perfect option. Patient data and information can be accessed for review after obtaining permission from the patient without any disclosure of her name.

Skip to main content. If you have symptoms of hypoglycemia several times a week or more, see your health care provider. You may need to change your medication dosage or timing, or otherwise adjust your diabetes treatment regimen. Low blood sugar is most common among people who take insulin, but it can also occur if you're taking certain oral diabetes medications.
Most of the body's glucose comes from food. The hormone insulin lowers blood sugar glucose levels when blood sugar is too high. If you have type 1 or type 2 diabetes and need insulin to control your blood sugar, taking more insulin than you need can cause your blood sugar level to drop too low and result in hypoglycemia.
Your blood sugar can also drop too low if, after taking your diabetes medication, you eat less than usual, or if you exercise more than you typically do, which uses extra glucose. Maintaining the balance between insulin, food and activity isn't always easy.
But your health care provider, certified diabetes care and education specialist, and registered dietitian can work with you to try to prevent low blood sugar levels.
If you ignore the symptoms of hypoglycemia too long, you may lose consciousness. That's because your brain needs glucose to function. Recognize the signs and symptoms of hypoglycemia early, because if untreated, hypoglycemia can lead to:. Take your early symptoms seriously.
Diabetic hypoglycemia can increase the risk of serious — even deadly — accidents. On this page. When to see a doctor.
Risk factors. A Book: The Essential Diabetes Book. Early warning signs and symptoms Initial signs and symptoms of diabetic hypoglycemia include: Looking pale pallor Shakiness Dizziness or lightheadedness Sweating Hunger or nausea An irregular or fast heartbeat Difficulty concentrating Feeling weak and having no energy fatigue Irritability or anxiety Headache Tingling or numbness of the lips, tongue or cheek.
Nighttime signs and symptoms If diabetic hypoglycemia occurs when you're sleeping, signs and symptoms that may disturb your sleep include: Damp sheets or nightclothes due to perspiration Nightmares Tiredness, irritability or confusion upon waking.
Severe signs and symptoms If diabetic hypoglycemia isn't treated, signs and symptoms of hypoglycemia worsen and can include: Confusion, unusual behavior or both, such as the inability to complete routine tasks Loss of coordination Difficulty speaking or slurred speech Blurry or tunnel vision Inability to eat or drink Muscle weakness Drowsiness Severe hypoglycemia may cause: Convulsions or seizures Unconsciousness Death, rarely Symptoms can differ from person to person or from episode to episode.
If you're with someone who is not responding loses consciousness or can't swallow due to low blood sugar: Don't inject insulin, as this will cause blood sugar levels to drop even further Don't give fluids or food, because these could cause choking Give glucagon by injection or a nasal spray Call or emergency services in your area for immediate treatment if glucagon isn't on hand, you don't know how to use it, or the person isn't responding If you have symptoms of hypoglycemia several times a week or more, see your health care provider.

Common causes of diabetic hypoglycemia include: Taking too much insulin or diabetes medication Not eating enough Postponing or skipping a meal or snack Increasing exercise or physical activity without eating more or adjusting your medications Drinking alcohol.
Blood sugar regulation Most of the body's glucose comes from food. Some people have a greater risk of diabetic hypoglycemia, including: People using insulin People taking diabetes drugs called sulfonylureas, such as glipizide Glucotrol , glimepiride Amaryl or glyburide Diabeta, Glynase Young children and older adults Those with impaired liver or kidney function People who've had diabetes for a long time People who don't feel low blood sugar symptoms hypoglycemia unawareness Those taking multiple medications Anyone with a disability that prevents a quick response to falling blood sugar levels People who drink alcohol.
Recognize the signs and symptoms of hypoglycemia early, because if untreated, hypoglycemia can lead to: Seizures Loss of consciousness Death Take your early symptoms seriously. To help prevent diabetic hypoglycemia: Monitor your blood sugar. Depending on your treatment plan, you may check and record your blood sugar level several times a week or multiple times a day.
Careful monitoring is the only way to make sure that your blood sugar level remains within your target range. Don't skip or delay meals or snacks.
If you take insulin or oral diabetes medication, be consistent about the amount you eat and the timing of your meals and snacks. Measure medication carefully and take it on time.
Take your medication as recommended by your health care provider. Adjust your medication or eat additional snacks if you increase your physical activity. The adjustment depends on the blood sugar test results, the type and length of the activity, and what medications you take.
Follow your diabetes treatment plan when making adjustments. Eat a meal or snack with alcohol, if you choose to drink. Drinking alcohol on an empty stomach can cause hypoglycemia.
Alcohol may also cause delayed hypoglycemia hours later, making blood sugar monitoring even more important. Record your low glucose reactions.
This can help you and your health care team identify patterns contributing to hypoglycemia and find ways to prevent them. Carry some form of diabetes identification so that in an emergency others will know that you have diabetes. Use a medical identification necklace or bracelet and wallet card.

Knowing how to identify low blood sugar is important because it can be dangerous if left untreated. Read more about what causes low blood sugar and common symptoms. How you react to low blood sugar may not be the same as how someone else with low blood sugar reacts. Common symptoms may include:.

Hypoglycemia is often related to diabetes treatment. But other drugs and a variety of conditions — many rare — can cause low blood sugar in people who don't have diabetes. Hypoglycemia needs immediate treatment. But your numbers might be different.
