Signs You Have Low Blood Sugar

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 >>

Symptoms Of Low Blood Sugar

Symptoms Of Low Blood Sugar

You may have these symptoms when your blood sugar has dropped below 70 milligrams per deciliter (mg/dL) . When you have had diabetes for many years, you may not always develop symptoms of mild low blood sugar. Some young children with diabetes cannot recognize symptoms of low blood sugar. Others can, but not every time. To be safe, the parents need to do a home blood sugar test whenever they suspect low blood sugar in a child. Sweating (almost always present). Check for sweating on the back of your neck at your hairline. These symptoms may go away shortly after you eat food that contains sugar. If your blood sugar continues to drop (below 40 mg/dL), your behavior may change. Symptoms may include: Personality changes, such as anger or crying. Symptoms of severe low blood sugar (usually below 20 mg/dL) include: If your blood sugar drops while you are sleeping, your partner or other family members may notice that you are sweating and behaving differently. Signs of low blood sugar at night ( nocturnal hypoglycemia ) include: Attempting to get out of bed or accidentally rolling out of bed.

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 Symptoms And Ranges

Low Blood Sugar Symptoms And Ranges

Low blood sugar (hypoglycemia) definition and facts Hypoglycemia is the medical term for low blood sugar. It typically occurs as a side effect of medications for diabetes. The normal range of blood glucose is from 70 to 100 mg/dL in an individual without diabetes, Most people will feel the effects and symptoms of low blood sugar when blood glucose levels are lower than 50 mg/dL. Low blood sugar is treated by giving a readily absorbed source of sugar, including soft drinks, juice, or foods containing sugar. If the hypoglycemia has progressed to the point at which the patient cannot take anything by mouth, an injection of glucagon may be given. Glucagon is a hormone that causes a fast release of glucose from the liver. Hypoglycemia or low blood sugar is syndrome that results from low blood sugar. The severity and symptoms of hypoglycemia can vary from person to person. Blood tests can diagnose low blood sugar, and symptoms resolve when the levels of sugar in the blood return to the normal range. The medical term for blood sugar is blood glucose. What can cause low blood sugar? Despite advances in the treatment of diabetes, low blood sugar episodes occur as a side effect of many treatments for diabetes. In fact, these episodes are often the limiting factor in achieving optimal blood sugar control, because many medications that are effective in treating diabetes carry the risk of lowering the blood sugar level too much, causing symptoms. In large scale studies looking at tight control in both type 1 and type 2 diabetes, low blood sugars occurred more often in the patients who were managed most intensively. This is important for patients and physicians to recognize, especially as the goal for treating patients with diabetes becomes tighter control of blood sugar. While peopl 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.

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 >>

7 Signs You Have Low Blood Sugar

7 Signs You Have Low Blood Sugar

“Low blood sugar” is one of those terms we’ve all heard thrown around a bunch but probably don’t know much about. It’s understandable that you’d feel a little cranky when a last-minute work meeting or general busyness forces you to push back a meal. But how do you know if you're annoyed due to low blood sugar or if your irritability is due to regular old hanger? “This is a topic that actually comes up quite a bit for me with patients and clients,” Jessica Cording, a New York-based R.D., tells SELF. Low blood sugar, also known as hypoglycemia, happens when levels of your blood glucose—an important energy source for your body—drop below normal, according to the National Institutes of Health. “Because our bodies require glucose for fuel, maintaining a steady stream of blood glucose is critical to keep your body functioning,” Karen Ansel, R.D.N., co-author of The Calendar Diet: A Month by Month Guide to Losing Weight While Living Your Life, tells SELF. We get our glucose from food, which explains why someone may complain that they have low blood sugar when they haven’t eaten recently. But along with not having enough to eat, certain medications or overdoing it with alcohol can cause low blood sugar in otherwise healthy people, Ansel says. Those people may experience symptoms like feeling shaky, irritable, or weak, says Cording, who notes that people can also feel anxious, start sweating, or become confused. And people with medical conditions like diabetes or hepatitis are more likely to experience complications from low blood sugar, which can be dangerous for them, Ansel says. “If it gets really severe, you pass out because your body has no energy to do what it needs to do,” says Cording. But chances are that you don't have to worry about low b Continue reading >>

Effects Of Low Blood Sugar On The Body

Effects Of Low Blood Sugar On The Body

The Effects of low blood sugar on the Body Every cell in your body needs sugar (glucose) to function. When your blood sugar levels drop too low, your cells become starved for energy. Initially, that can cause minor symptoms, but if you don’t get your blood sugar levels up soon, you’re at risk of serious complications. When your blood sugar (glucose) levels fall below the normal range, it’s called hypoglycemia, or insulin shock. Low blood sugar can happen when you skip a meal. It can also happen if your pancreas releases more insulin than it should after you’ve eaten. The most common reason for low blood sugar is diabetes. In type 1 diabetes, the pancreas can no longer produce insulin. In type 2 diabetes, the pancreas doesn’t make enough, or your body can’t use it properly. To keep blood sugar levels from rising too much (hyperglycemia), you need the right amount of insulin. With insufficient insulin, your blood sugar levels rise. Too much, and your blood sugar levels can plummet. Another possible cause of low blood sugar is drinking too much alcohol, especially on an empty stomach. This can interfere with the liver’s ability to release stored glucose into your bloodstream. Hepatitis and other problems with your liver can also lead to low blood sugar. Other causes include kidney disorders, anorexia nervosa, a pancreatic tumor, or adrenal gland disorders. There are a variety of symptoms of low blood sugar, but the only way to be sure what your blood glucose levels are is by taking a blood glucose test. Generally, blood sugar levels below 70 milligrams per deciliter (mg/dL) are considered too low, according to the American Diabetes Association. If you have diabetes, it’s important to monitor your blood sugar levels often. Low blood sugar can come on quickly 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 >>

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 >>

What A Low Blood Sugar Feels Like

What A Low Blood Sugar Feels Like

In this article, we will explore what low blood sugar feels like for different people with diabetes. We will look at the symptoms, how they can change over time, and how they are often different from person to person. We will look at planning ahead, and the treatment of hypoglycemia, hereafter referred to as “low blood sugar.” To get started, patients with Type 1 and Type 2 diabetes were interviewed and asked the question: What is it like and what do you do when life hands you the low blood sugar agenda for the day? Describe your experience. Melissa’s story Melissa is usually gung-ho and ready to go for the day, but when she is handed the low blood sugar agenda, it takes all the wind out of her “cells.” They feel wrinkled up and emaciate. Here is how Melissa describes her low blood sugars: I imagine you, (you wrinkly old emaciated cell with no food in you), as a grumpy old man. I scream at you, though I can’t move. No, I won’t take your stifling agenda! I have to work after all. My kids need me to take them to dance class after school. I’m reluctant to take your agenda, packed with the helplessness that is my poison pill of the day. If I believe those positive self-help type blogs, then I would know that to decide you are happy determines your destination for the day. If you have diabetes, that’s a crock. With diabetes, your low blood sugar determines your agenda, and ultimately what you will be able to do for the day. When it gets below 70, or dips severely low- it begs and screams to be addressed! Especially if it dips fast, then I’m in trouble. Every cell in my body screams out. If it’s too low, I can’t move to do anything about it! Often I get a little dizzy feeling, and then I know I have to treat. I will get the shakes so bad that I can’t Continue reading >>
