Is Low Glucose A Sign Of Diabetes?

10 Warning Signs Of Low Blood Sugar

10 Warning Signs Of Low Blood Sugar

Hypoglycemia, or low blood sugar, is common among people with diabetes and can occur even when you're carefully managing the condition. "Hypoglycemia happens when the amount of blood glucose (sugar in the blood) drops to a level that's too low to sustain normal functioning," says Erin Palinski-Wade, RD, CDE, author of 2 Day Diabetes Diet. "In most people, this is defined as a blood-sugar level below 70 milligrams per deciliter." A review published in June 2015 in the journal PLoS One found that among people with type 2 diabetes, this is a far too common occurrence. Individuals with the condition had an average of 19 mild episodes of hypoglycemia per year, and nearly one severe episode per year on average. Low blood sugar was particularly common among those taking insulin. This decrease in blood sugar levels can cause both short-term complications, like confusion and dizziness, as well as more serious, long-term complications. Left untreated, it can lead to a coma and even death. To prevent hypoglycemia and its dangerous side effects, it's crucial to monitor your glucose levels and treat low blood sugar as soon as you become aware of it. Pay attention to these telltale signs of dipping blood sugar levels to make sure yours stays under control: 1. Ravenous Hunger If you've already eaten but still aren't satisfied, or if you suddenly, inexplicably feel as if you're starving, your body is signaling that it needs more glucose. Work with your healthcare team to determine the exact amount of sugar your body needs. A good starting point is the American Diabetes Association's recommendation to eat between 15 and 20 grams (g) of sugar or carbohydrates with each snack, and between 40 and 65 g at each meal. Some good options include 2 tablespoons of raisins, 4 ounces of fruit juice Continue reading >>

Low Blood Sugar? 8 Warning Signs If You Have Diabetes

Low Blood Sugar? 8 Warning Signs If You Have Diabetes

Do you know the No. 1 cause of blood sugar dips? Changes in food intake. You may go too long without eating carbohydrates, or step up your activity without adding extra food. Certain diabetes medications, such as insulin, can cause low blood sugar as well.  Either way, these situations can cause hypoglycemia, or low blood sugar.

Policy And it’s sometimes difficult to tell for sure when you’re experiencing problems. Symptoms may vary from person to person; not everyone has the same warning signs. The problems are sometimes mild, but if they’re severe and left untreated, they could lead to seizures or unconsciousness. Here’s what you need to know to recognize hypoglycemia when it happens — as well as steps you can take to help avoid the problem. What are the most common signs of trouble? Health professionals typically define hypoglycemia as blood sugar in a non-pregnant adult that is lower than 70mg/dl. However, experts don’t define the severity by the number, but rather by the symptoms: Mild. In this case, low blood sugar can be treated by the person with diabetes alone. Moderate. The person experiencing low blood sugar is alert enough to ask for help, but he or she does require assistance. Severe. This person is completely unable to self-treat and may be awake or unconscious.  Talk to your doctor to see what target levels are safe for you. If you suspect you’re dealing with hypoglycemia, here are the most common symptoms to watch for: Sweating– One of the first signs of hypoglycemia is sweating or clammy skin. It often occurs regardless of the temperature outside. Hunger – Continue reading >>

Nondiabetic Hypoglycemia

Nondiabetic Hypoglycemia

What is non-diabetic hypoglycemia? Hypoglycemia is the condition when your blood glucose (sugar) levels are too low. It happens to people with diabetes when they have a mismatch of medicine, food, and/or exercise. Non-diabetic hypoglycemia, a rare condition, is low blood glucose in people who do not have diabetes. There are two kinds of non-diabetic hypoglycemia: Reactive hypoglycemia, which happens within a few hours of eating a meal Fasting hypoglycemia, which may be related to a disease Glucose is the main source of energy for your body and brain. It comes from what we eat and drink. Insulin, a hormone, helps keep blood glucose at normal levels so your body can work properly. Insulin’s job is to help glucose enter your cells where it’s used for energy. If your glucose level is too low, you might not feel well. What causes non-diabetic hypoglycemia? The two kinds of non-diabetic hypoglycemia have different causes. Researchers are still studying the causes of reactive hypoglycemia. They know, however, that it comes from having too much insulin in the blood, leading to low blood glucose levels. Types of nondiabetic hypoglycemia Reactive hypoglycemia Having pre-diabetes or being at risk for diabetes, which can lead to trouble making the right amount of insulin Stomach surgery, which can make food pass too quickly into your small intestine Rare enzyme deficiencies that make it hard for your body to break down food Fasting hypoglycemia Medicines, such as salicylates (such as aspirin), sulfa drugs (an antibiotic), pentamidine (to treat a serious kind of pneumonia), quinine (to treat malaria) Alcohol, especially with binge drinking Serious illnesses, such as those affecting the liver, heart, or kidneys Low levels of certain hormones, such as cortisol, growth hormone, glu Continue reading >>

Type 1 Diabetes Low Blood Sugar Symptoms

Type 1 Diabetes Low Blood Sugar Symptoms

Type 1 diabetes in an autoimmune disease where a person’s pancreas doesn’t produce insulin—a hormone needed to convert food into energy. It affects children and adults, comes on suddenly, and it cannot be prevented or cured. Hypoglycemia, or low blood sugar, is a common and dangerous occurance with type 1 diabetes. If your blood sugar gets too low it may lead to insulin shock, which is life-threatening if not cared for. Low blood sugar can happen when your body has too little food—or glucose—or when it produces too much insulin. Type 1 diabetes hypoglycemia symptoms So what are the low blood sugar symptoms you should look out for? It’s important to realize that the signs of low blood sugar will vary depending on the person. However, people with type 1 diabetes—whether it’s been diagnosed or not—may experience one or more of the following: -Sweating and shaking -Blurry vision -Poor coordination -Dizziness or feeling lightheaded -Difficulty concentrating -Feeling anxious or irritable -Hunger or nausea -Erratic changes in behavior What to do if you experience low blood glucose symptoms Severely low blood-sugar levels can lead to hypoglycemic seizures, unconsciousness, coma, and death if left untreated. That’s why it’s important to see a doctor if you think you have low blood sugar so he or she can check your blood-glucose levels—look into whether type 1 diabetes may be a cause—and provide the necessary treatment. Your support is more critical than ever Continue reading >>

This happens to nearly everyone from time to time. It's easy to correct and usually nothing to worry about. But low blood sugar, or hypoglycemia, can also be an ongoing problem. It occurs when the level of sugar in your blood drops too low to give your body energy. Ongoing problems with low blood sugar can be caused by: Medicines. Metabolic problems. Alcohol use. Symptoms can be different depending on how low your blood sugar level drops. Mild hypoglycemia can make you feel hungry or like you want to vomit. You could also feel jittery or nervous. Your heart may beat fast. You may sweat. Or your skin might turn cold and clammy. Moderate hypoglycemia often makes people feel short-tempered, nervous, afraid, or confused. Your vision may blur.

To diagnose hypoglycemia, your doctor will do a physical exam and ask you questions about your health and any medicines you take. You will need blood tests to check your blood sugar levels. Some tests might include not eating (fasting) and watching for symptoms. Other tests might involve eating a meal that could cause symptoms of low blood sugar seve Continue reading >>

Hypoglycaemia (low Blood Sugar)

Hypoglycaemia (low Blood Sugar)

Introduction Hypoglycaemia, or a "hypo", is an abnormally low level of glucose in your blood (less than four millimoles per litre). When your glucose (sugar) level is too low, your body doesn't have enough energy to carry out its activities. Hypoglycaemia is most commonly associated with diabetes, and mainly occurs if someone with diabetes takes too much insulin, misses a meal or exercises too hard. In rare cases, it's possible for a person who doesn't have diabetes to experience hypoglycaemia. It can be triggered by malnutrition, binge drinking or certain conditions, such as Addison's disease. Read more about the causes of hypoglycaemia Symptoms of hypoglycaemia Most people will have some warning that their blood glucose levels are too low, which gives them time to correct them. Symptoms usually occur when blood sugar levels fall below four millimoles (mmol) per litre. Typical early warning signs are feeling hungry, trembling or shakiness, and sweating. In more severe cases, you may also feel confused and have difficulty concentrating. In very severe cases, a person experiencing hypoglycaemia can lose consciousness. It's also possible for hypoglycaemia to occur during sleep, which can cause excess sweating, disturbed sleep, and feeling tired and confused upon waking. Read more about the symptoms of hypoglycaemia Correcting hypoglycaemia The immediate treatment for hypoglycaemia is to have some food or drink that contains sugar, such as dextrose tablets or fruit juice, to correct your blood glucose levels. After having something sugary, you may need to have a longer-acting "starchy" carbohydrate food, such as a sandwich or a few biscuits. If hypoglycaemia causes a loss of consciousness, an injection of the hormone glucagon can be given to raise blood glucose levels and Continue reading >>

Low Blood Sugar (hypoglycemia)

Low Blood Sugar (hypoglycemia)

Low blood sugar, also known as hypoglycemia, can be a dangerous condition. Low blood sugar can happen in people with diabetes who take medicines that increase insulin levels in the body. Taking too much medication, skipping meals, eating less than normal, or exercising more than usual can lead to low blood sugar for these individuals. Blood sugar is also known as glucose. Glucose comes from food and serves as an important energy source for the body. Carbohydrates — foods such as rice, potatoes, bread, tortillas, cereal, fruit, vegetables, and milk — are the body’s main source of glucose. After you eat, glucose is absorbed into your bloodstream, where it travels to your body’s cells. A hormone called insulin, which is made in the pancreas, helps your cells use glucose for energy. If you eat more glucose than you need, your body will store it in your liver and muscles or change it into fat so it can be used for energy when it’s needed later. Without enough glucose, your body cannot perform its normal functions. In the short term, people who aren’t on medications that increase insulin have enough glucose to maintain blood sugar levels, and the liver can make glucose if needed. However, for those on these specific medications, a short-term reduction in blood sugar can cause a lot of problems. Your blood sugar is considered low when it drops below 70 mg/dL. Immediate treatment for low blood sugar levels is important to prevent more serious symptoms from developing. Explaining low blood sugar in layman's terms » Symptoms of low blood sugar can occur suddenly. They include: rapid heartbeat sudden nervousness headache hunger shaking sweating People with hypoglycemic unawareness do not know their blood sugar is dropping. If you have this condition, your blood sugar Continue reading >>

All About Hypoglycemia (low Blood Sugar)

All About Hypoglycemia (low Blood Sugar)

Hypoglycemia refers to an abnormally low level of sugar, or glucose, in the blood. Hypoglycemia is not a disease in itself, it is a sign of a health problem. The brain uses a lot of energy and needs glucose to function. Because the brain cannot store or manufacture glucose, it needs a continuous supply. Signs of low blood sugar include hunger, trembling, heart racing, nausea, and sweating. Hypoglycemia is commonly linked with diabetes, but many other conditions can also cause low blood sugar. This article will discuss the causes, diagnosis, and treatment of hypoglycemia, and the difference between hypoglycemia and hyperglycemia. We will also look at how to prevent it. Here are some key points about hypoglycemia. More detail is in the main article. Hypoglycemia is not a disease but a symptom of another condition. Early symptoms include hunger, sweating, and trembling. A common cause is diabetes. Alcohol abuse and kidney disorders can also lower blood sugar levels. What is hypoglycemia? Hypoglycemia is a condition where there is not enough glucose, or sugar, in the blood. Levels of blood sugar are below 4 mmol/L (72mg/dL). Adults and children with mild hypoglycemia may experience the following early symptoms: hunger tremor or trembling sweating irritability a pale face heart palpitations accelerated heart rate tingling lips dizziness weakness Severe hypoglycemia is sometimes called diabetic shock. It may involve: concentration problems confusion irrational and disorderly behavior, similar to intoxication inability to eat or drink Complications If a person does not take action when symptoms of hypoclycemia appear, it can lead to: A person who regularly experiences hypoglycemia may become unaware that it is happening. They will not notice the warning signs, and this can lea Continue reading >>

Low Blood Sugar

Low Blood Sugar

People with diabetes get hypoglycemia () when their bodies don't have enough sugar to use as fuel. It can happen for several reasons, including diet, some medications and conditions, and exercise. If you get hypoglycemia, write down the date and time when it happened and what you did. Share your record with your doctor, so she can look for a pattern and adjust your medications. Call your doctor if you have more than one unexplained low blood sugar reaction in a week. Most people feel symptoms of hypoglycemia when their blood sugar is 70 milligrams per deciliter (mg/dL) or lower. Each person with diabetes may have different symptoms of hypoglycemia. You'll learn to spot yours. Early symptoms include: Confusion Dizziness Feeling shaky Hunger Headaches Irritability Pounding heart; racing pulse Pale skin Sweating Trembling Weakness Anxiety Without treatment, you might get more severe symptoms, including: Poor coordination Poor concentration Numbness in mouth and tongue Passing out Ask your doctor if any of your medicines can cause low blood sugar. Insulin treatment can cause low blood sugar, and so can a type of diabetes medications called "sulfonylureas." Commonly used sulfonylureas include: Glibenclamide (Glyburide, Micronase) Gliclazide Older, less common sulfonlyureas tend to cause low blood sugar more often than some of the newer ones. Examples of older drugs include: You can also get low blood sugar if you drink alcohol or take allopurinol (Zyloprim), aspirin, Benemid, probenecid (Probalan), or warfarin (Coumadin) with diabetes medications. You shouldn't get hypoglycemia if you take alpha-glucosidase inhibitors, biguanides (such as metformin), and thiazolidinediones alone, but it can happen when you take them with sulfonylureas or insulin. You can get low blood sugar Continue reading >>

Can You Have Low Blood Sugar With Type 2 Diabetes?

Can You Have Low Blood Sugar With Type 2 Diabetes?

back to Overview Know-how Type 2 A tag-team approach on low blood sugar with type 2 diabetes. Markus recently wrote an article on our German language blog talking about low blood sugar with type 2 diabetes. The question (“can I have low blood sugar with type 2 diabetes?”) is very common, and it’s easy to see why it’s of concern. So I’ve helped Markus bring his German post to life here in English. I hope it helps! Here’s Markus: Low blood sugar In 2014, results from the DAWN2 study were announced. It was the largest study of its kind (15,000 participants) on the “fears & needs of people with diabetes and their families.” One result stood out: The gravest fears are related to low blood sugars, especially at night. Up to 69% of the participants share this fear! So! Can you have low blood sugar with type 2 diabetes? Yes! Of course! But let’s think about who exactly is at risk – and why. It’s common to think: Type 1 diabetes = at risk for lows Type 2 diabetes = not at risk for lows But that isn’t correct at all, so we should wipe it from our mind. So… what do I need to know? Maybe it’s more accurate to say that people with type 2 diabetes who take certain types of medication are more at risk for lows. We’re getting closer! But to get to the truth, we should take a look at someone without diabetes. Is it possible for them to have lows, too? Theoretically yes, especially if doing long-lasting physical activities without proper food intake. Additionally, extreme stress and binge drinking are also common causes of low blood sugar for people without diabetes. However, it’s pretty rare because as soon as BG’s drop below 80 mg/dl (4.4 mmol/L), the natural counterregulatory system kicks in, raising blood sugar back to normal levels. I’ve never exp Continue reading >>

Low Blood Sugar: Causes, Warning Signs And Treatments

Low Blood Sugar: Causes, Warning Signs And Treatments

Low blood sugar, or hypoglycemia, is the most common and most dangerous condition for many people with type 1 diabetes (T1D). Very low blood sugar may lead to insulin shock, which can be life threatening if not treated promptly. Low blood sugar occurs when the body has too little food/glucose or too much insulin. The following are all potential reasons that a person with diabetes might have low blood sugar: Too much insulin taken Eating less than usual Eating later than usual Insulin was injected at a site on the body where the absorption rate is faster than usual Injecting extra insulin after forgetting about a previous dose More exercise than normal Illness or injury Other hormones Medication interaction The following is a list of general symptoms that indicate low blood sugar (the person with T1D may exhibit one or more of these and symptoms may change from event to event) Dizziness Nervousness Personality change/irrational behavior Blurry vision Shakiness Nausea Crying Sluggishness Sweating Poor coordination Hunger Lightheadedness Irritability Drowsiness Erratic response to questions Inability to concentrate Severe symptoms (symptoms as listed above, plus): Convulsions or seizure Loss of consciousness A blood-glucose meter reading below the target range specified by the physician indicates low blood sugar. The following are general treatments for low blood sugar. The physician and parents (for a child) should determine what course to follow. Please note that people with T1D have symptoms of low blood sugar at various readings. Some people with T1D feel perfectly fine at readings below 70. Others begin to show low blood-sugar symptoms at readings somewhat above 70. If blood-sugar levels are slightly low and the person is alert and lucid, he or she should: Not exercis Continue reading >>

Hypoglycemia

Hypoglycemia

Print Overview Hypoglycemia is a condition characterized by an abnormally low level of blood sugar (glucose), your body's main energy source. Hypoglycemia is commonly associated with the treatment of diabetes. However, a variety of conditions, many of them rare, can cause low blood sugar in people without diabetes. Like fever, hypoglycemia isn't a disease itself — it's an indicator of a health problem. Immediate treatment of hypoglycemia involves quick steps to get your blood sugar level back into a normal range — about 70 to 110 milligrams per deciliter, or mg/dL (3.9 to 6.1 millimoles per liter, or mmol/L) — either with high-sugar foods or medications. Long-term treatment requires identifying and treating the underlying cause of hypoglycemia. Symptoms Similar to the way a car needs gas to run, your body and brain need a constant supply of sugar (glucose) to function properly. If glucose levels become too low, as occurs with hypoglycemia, it can cause these signs and symptoms: Heart palpitations Fatigue Pale skin Shakiness Anxiety Sweating Hunger Irritability Tingling sensation around the mouth Crying out during sleep As hypoglycemia worsens, signs and symptoms may include: Confusion, abnormal behavior or both, such as the inability to complete routine tasks Visual disturbances, such as blurred vision Seizures Loss of consciousness People with severe hypoglycemia may appear as if they're intoxicated. They may slur their words and move clumsily. Many conditions other than hypoglycemia may cause these signs and symptoms. A blood sample to test your blood sugar level at the time of these signs and symptoms is how to know for sure that hypoglycemia is the cause. When to see a doctor Seek a doctor's help immediately if: You have what may be symptoms of hypoglycemia an Continue reading >>
