Low Blood Sugar

See Hypoglycemia, and Hyperinsulism.Encyclopedia Entry for Low Blood Sugar :Low blood sugar - newborns. Babies need blood sugar (glucose) for energy. Most of that glucose is used by the brain. The baby gets glucose from the mother through the placenta before birth. After birth, the baby gets glucose from the mother through her milk or from formula, and the baby also produces it in the liver. Glucose level can drop if: There is too much insulin in the blood. Insulin is a hormone that pulls glucose from the blood. The baby is not producing enough glucose. The baby's body is using more glucose than is being produced. The baby is not able to feed enough to keep the glucose level up. Neonatal hypoglycemia occurs when the newborn's glucose level causes symptoms or is below the level considered safe for the baby's age. It occurs in about 1 to 3 out of every 1,000 births. Low blood sugar level is more likely in infants with one or more of these risk factors: Born early, has a serious infection, or needed oxygen right after delivery Mother has diabetes (these infants are often larger than normal) Have slower than usual growth in the womb during pregnancy Are smaller or larger in size than normal for their gestational age.Infants with low blood sugar may not have symptoms. If your baby has one of the risk factors for low blood sugar, nurses in the hospital will check your baby's blood sugar level, even if there are no symptoms. Also, blood sugar level is very often checked for babies with these symptoms: Bluish-colored or pale skin Breathing problems, such as pauses in breathing (apnea), rapid breathing, or a grunting sound Irritability or listlessness Loose or floppy muscles Poor feeding or vomiting Problems keeping the body warm Tremors, shakiness, sweating, or seizures.Newborns at risk for hypoglycemia should have a blood test to measure blood sugar level every few hours after birth. This will be done using a heel stick. The health care provider should continue taking blood tests until the baby's glucose level stays normal for about 12 to 24 hours. Other possible tests: Newborn screening for metabolic disorders, including blood and urine tests.Infants with a low blood sugar level will need to receive extra feedings with mother's milk or formula. Babies who are breast-fed may need to receive extra formula if the mother is not able to produce enough milk. (Hand expression and massage can help mothers express more milk.) Sometimes a sugar gel may be given by mouth temporarily if there is not enough milk. The infant may need a sugar solution given through a vein (intravenously) if unable to eat by mouth, or if the blood sugar level is very low. Treatment will be continued until the baby can maintain blood sugar level. This may take hours or days. Infants who were born early, have an infection, or were born at a low weight may need to be treated for a longer period of time. If the low blood sugar continues, in rare cases, the baby may also receive medicine to increase blood sugar level. In very rare cases, newborns with very severe hypoglycemia who do not improve with treatment may need surgery to remove part of the pancreas (to reduce insulin production).The outlook is good for newborns who do not have symptoms, or who respond well to treatment. However, low blood sugar level can return in a small number of babies after treatment. The condition is more likely to return when babies are taken off feedings given through a vein before they are fully ready to eat by mouth. Babies with more severe symptoms are more likely to develop learning problems. This is more often true for babies who are at a lower-than-average weight or whose mother has diabetes.Severe or persistent low blood sugar level may affect the baby's mental function. In rare cases, heart failure or seizures may occur. However, these problems may also be due to the underlying cause of the low blood sugar, rather than a result of the low blood sugar itself.If you have diabetes during pregnancy, work with your provider to control your blood sugar level. Be sure that your newborn's blood sugar level is monitored after birth.Neonatal hypoglycemia.Devaskar SU, Garg M. Disorders of carbohydrate metabolism in the neonate.Encyclopedia Entry for Low Blood Sugar :Low blood sugar - self-care. Low blood sugar is called hypoglycemia. A blood sugar level below 70 mg/dL (3.9 mmol/L) is low and can harm you. A blood sugar level below 54 mg/dL (3.0 mmol/L) is a cause for immediate action. You are at risk for low blood sugar if you have diabetes and are taking any of the following diabetes medicines: Insulin Glyburide (Micronase), glipizide (Glucotrol), glimepiride (Amaryl), repaglinide (Prandin), or nateglinide (Starlix) Chlorpropamide (Diabinese), tolazamide (Tolinase), acetohexamide (Dymelor), or tolbutamide (Orinase) You are also at increased risk of having low blood sugar if you have had previous low blood sugar levels.Know how to tell when your blood sugar is getting low. Symptoms include: Weakness or feeling tired Shaking Sweating Headache Hunger Feeling uneasy, nervous, or anxious Feeling cranky Trouble thinking clearly Double or blurry vision Fast or pounding heartbeat Sometimes your blood sugar may be too low even if you do not have symptoms. If it gets too low, you may: Faint Have a seizure Go into a coma Some people who have had diabetes for a long time stop being able to sense low blood sugar. This is called hypoglycemic unawareness. Ask your health care provider if wearing a continuous glucose monitor and sensor can help you detect when your blood sugar is getting too low in order to help prevent symptoms.Talk with your provider about when you should check your blood sugar every day. People who have low blood sugar need to check their blood sugar more often. The most common causes of low blood sugar are: Taking your insulin or diabetes medicine at the wrong time Taking too much insulin or diabetes medicine Not eating enough during meals or snacks after you have taken insulin or diabetes medicine Skipping meals Waiting too long after taking your medicine to eat your meals Exercising a lot or at a time that is unusual for you Not checking your blood sugar or not adjusting your insulin dose before exercising Drinking alcohol.Preventing low blood sugar is better than having to treat it. Always have a source of fast-acting sugar with you. When you exercise , check your blood sugar levels. Make sure you have snacks with you. Talk to your provider about reducing insulin doses on days that you exercise. Ask your provider if you need a bedtime snack to prevent low blood sugar overnight. Protein snacks may be best. DO NOT drink alcohol without eating food. Women should limit alcohol to 1 drink a day and men should limit alcohol to 2 drinks a day. Family and friends should know how to help. They should know: The symptoms of low blood sugar and how to tell if you have them. How much and what kind of food they should give you. When to call for emergency help. How to inject glucagon, a hormone that increases your blood sugar. Your doctor or nurse will tell you when to use this medicine. If you have diabetes, always wear a medical alert bracelet or necklace. This helps emergency medical workers know you have diabetes.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. Eat something that has about 15 grams (g) of carbohydrates. Examples are 3 glucose tablets, one half cup (4 ounces or 237 mL) of fruit juice or regular, non-diet soda, 5 or 6 hard candies, 1 tablespoon (tbsp) or 15 mL of sugar, plain or dissolved in water, or 1 tbsp (15 mL) of honey or syrup. Wait about 15 minutes before eating any more. Be careful not to eat too much. This can cause high blood sugar and weight gain. Check your blood sugar again. If you do not feel better in 15 minutes and your blood sugar is still lower than 70 mg/dL (3.9 mmol/L), eat something with 15 g of carbohydrate again. You may need to eat a snack with carbohydrates and protein if your blood sugar is in a safer range -- over 70 mg/dL (3.9 mmol/L) -- 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.If you use insulin and your blood sugar is frequently or consistently low, ask your doctor or nurse if you: Are injecting your insulin the right way Need a different type of needle Should change how much insulin you take Should change the kind of insulin you take DO NOT make any changes without talking to your doctor or nurse first. Sometimes hypoglycemia can be due to taking the wrong medicines. Check your medicines with your pharmacist.If signs of low blood sugar DO NOT improve after you have eaten a snack that contains sugar, have someone drive you to the emergency room or call your local emergency number (such as 911). DO NOT drive when your blood sugar is low. Get medical help right away for a person with low blood sugar if the person is not alert or cannot be awakened.Hypoglycemia - self care; Low blood glucose - self care.Medical alert bracelet Medical alert bracelet Glucose test Glucose test.American Diabetes Association. 6.

Hypoglycemia and hypoglycemic syndromes.Encyclopedia Entry for Low Blood Sugar :Low blood sugar. Insulin is a hormone made by the pancreas. Insulin is needed to move glucose into cells where it is stored or used for energy. Without enough insulin, glucose builds up in the blood instead of going into the cells. This leads to symptoms of diabetes. Low blood sugar occurs due to any of the following: Your body's sugar (glucose) is used up too quickly Glucose production by the body is too low or it is released into the bloodstream too slowly Too much insulin is in the bloodstream Low blood sugar is common in people with diabetes who are taking insulin or certain other medicines to control their diabetes. However, many other diabetes medicines do not cause low blood sugar. Exercise can also lead to low blood sugar in people taking insulin to treat their diabetes. Babies born to mothers with diabetes may have severe drops in blood sugar right after birth. In people who do not have diabetes, low blood sugar may be caused by: Drinking alcohol Insulinoma , which is a rare tumor in the pancreas that produces too much insulin Lack of a hormone, such as cortisol, growth hormone, or thyroid hormone Severe heart, kidney, or liver failure Infection that affects the whole body ( sepsis ) Some types of weight-loss surgery (usually 5 or more years after the surgery) Medicines not used to treat diabetes (certain antibiotics or heart drugs).Symptoms you may have when your blood sugar gets too low include: Double vision or blurry vision Fast or pounding heartbeat Feeling cranky or acting aggressive Feeling nervous Headache Hunger Shaking or trembling Sweating Tingling or numbness of the skin Tiredness or weakness Trouble sleeping Unclear thinking In many people with diabetes, low blood sugar occurs every time with nearly the same symptoms. Some symptoms, like hunger or sweating, occur when blood sugar is only slightly low. More severe symptoms, such as unclear thinking or seizure, occur when the blood sugar is much lower (less than 40 mg/dL or 2.2 mmol/L). Even if you do not have symptoms, your blood sugar could still be too low (called hypoglycemic unawareness). You may not even know you have low blood sugar until you faint, have a seizure , or go into a coma. If you have diabetes, ask your health care provider if wearing a continuous glucose monitor and sensor can help you detect when your blood sugar is getting too low to help prevent symptoms. If you have diabetes, keeping good control of your blood sugar can help prevent low blood sugar. Talk to your provider if you're not sure about the causes and symptoms of low blood sugar.When you have low blood sugar, the reading will be lower than 70 mg/dL (3.9 mmol/L) on your glucose monitor. Your provider may ask you to wear a small monitor that measures your blood sugar every 5 minutes (continuous glucose monitor). The device is often worn for 3 or 7 days. The data is downloaded to find out if you're having periods of low blood sugar that are going unnoticed. If you're admitted to the hospital, you'll likely have blood samples taken from your vein to: Measure your blood sugar level Diagnose the cause of your low blood sugar (these tests need to be carefully timed related to low blood sugar to make an accurate diagnosis).The goal of treatment is to correct your low blood sugar level. If you have diabetes, it is likely your provider told you how to treat yourself for low blood sugar. Treatment may include: Drinking juice Eating food Taking glucose tablets Or you may have been told to give yourself a shot of glucagon. This is a medicine that raises blood sugar. If low blood sugar is caused by an insulinoma, surgery to remove the tumor will be recommended.Severe low blood sugar is a medical emergency. It can cause seizures and brain damage. Severe low blood sugar that causes you to become unconscious is called hypoglycemic or insulin shock. Even one episode of severe low blood sugar may make it less likely for you to have symptoms that allow you to recognize another episode of low blood sugar.If signs of low blood sugar do not improve after you have eaten a snack that has sugar: Get a ride to the emergency room. DO NOT drive yourself. Call a local emergency number (such as 911) Get medical help right away for a person with diabetes or low blood sugar who: Becomes less alert Cannot be woken up.Hypoglycemia; Insulin shock; Insulin reaction; Diabetes - hypoglycemia.Food and insulin release Food and insulin release 15/15 rule 15/15 rule.American Diabetes Association. 6.
