Hypoglycemia

Hypoglycemia refers to low blood sugar, or technically a lower than normal blood glucose level. It is rarely encountered in pediatric practice outside of the newborn nursery, where it is a commonplace event. Profound hypoglycemia in the newborn can cause brain damage. Aggressive blood glucose monitoring of asymptomatic (nothing appears to be wrong) infants has been the standard. I think attitudes are softening in the era of cost-benefit analysis, since many babies seem to be subjected to large numbers of (in retrospect) needless blood glucose determinations compared to the actual number of significant problems identified. Symptoms of hypoglycemia are generally related to the body's efforts to raise the blood glucose level back to where it should be. These symptoms are really just the manifestations of adrenaline (epinephrine) release, which is the chief signal the body uses to mobilise stored glucose into the bloodstream. The most noticable adrenaline effects are nervousness, light-headedness, increased heart rate, and a particularly urgent sense of hunger. Headache is sometimes a symptom of hypoglycemia; I believe the explanation is brain neuronal cell dysfunction. In the newborn, symptoms of hypoglycemia include sweating, jitteriness, rapid breathing, rapid heart rate, pallor, or even apnea. Profound or very difficult to treat hypoglycemia in a newborn can signal the presence of rare but dangerous conditions such as galactosemia, growth hormone deficiency, insulin secreting tumors, or may reflect severe intrauterine growth restriction (IUGR). Hypoglycemia is the opposite of hyperglycemia - high blood glucose - which is the hallmark of diabetes. True hypoglycemia in children older than newborns is reasonably rare and is not the cause of the myriad complaints and condit Continue reading >>

Question: From Moraga, California, USA: My daughter was diagnosed with ketotic hypoglycemia at two years, 10 months after a bout of rotavirus. She has consistently been in the 75th percentile for height and 90th percentile for weight, so she does not appear to fit the standard child with ketotic hypoglycemia I have read about. The episode occurred after a trip to a high altitude where she was extremely active (we live at sea level). She started vomiting at 2 a.m. one night during our vacation and could hold nothing down the entire next day, not even a teaspoon of water. We drove home and took her to the Emergency Room (ER) almost 24 hours after the vomiting started. The doctor gave her suppositories to stop the vomiting, but performed no blood work, and we went home. She drank some Pedialyte and juice, about 16 ounces total, through the night and next morning. Around noon, she started vomiting again and could hold nothing down. Mild diarrhea also started. She became more lethargic and that night, around 2 a.m. (48 hours after the vomiting started and 24 hours after the first visit), she started vomiting bile. We took her back to the ER. Her sugar was 26 mg/dl [1.4 mmol/L]. It took a few hours for her sugar to get back over 80 mg/dl [4.4 mmol/L], where they wanted it. She was hospitalized and the doctors performed numerous tests on her, including a fasting blood sugar test, and found nothing out of the ordinary aside from the rotavirus. We saw an endocrinologist who had us test her blood sugar at home for a few weeks. Everything looked okay and we were told she had ketotic hypoglycemia. We just had to be careful to give her something to eat before bed and an early breakfast, which we do. Aside from getting grumpy when hungry, she has been fine since the episode a little Continue reading >>

Poor Specificity Of Low Growth Hormone And Cortisol Levels During Fasting Hypoglycemia For The Diagnoses Of Growth Hormone Deficiency And Adrenal Insufficiency

Poor Specificity Of Low Growth Hormone And Cortisol Levels During Fasting Hypoglycemia For The Diagnoses Of Growth Hormone Deficiency And Adrenal Insufficiency

Abstract OBJECTIVES. Fasting tests are used to identify the cause of hypoglycemia in children. The purposes of this study were to (1) determine whether growth hormone and cortisol levels obtained at the time of hypoglycemia in such tests can identify children with growth hormone and/or cortisol deficiency and (2) identify potential clinical factors that influence growth hormone and cortisol responses to hypoglycemia. STUDY DESIGN. The design consisted of chart review of all diagnostic fasting tests conducted over a 3-year period (n = 151). A normal growth hormone level was defined as ≥7.5 ng/mL, and a normal cortisol level was defined as ≥18 μg/dL. RESULTS. During the fasting tests, 84 children (median age: 1.3 years [2 days to 14.3 years]), became hypoglycemic, with blood glucose ≤50 mg/dL. Diagnoses included normal, ketotic hypoglycemia, hyperinsulinism, fatty acid–oxidation defects, glycogen-storage disease, and late dumping hypoglycemia. A total of 70% had growth hormone and cortisol levels less than the “normal” thresholds regardless of diagnosis. Of various factors (age, diagnosis, fast duration, duration blood glucose level of <60 mg/dL, and blood glucose nadir), only age was positively associated with cortisol, and none were consistently related to growth hormone. CONCLUSIONS. A singe low growth hormone or cortisol value at the time of fasting hypoglycemia has poor specificity for the respective diagnoses of growth hormone deficiency and adrenal insufficiency. Abstract OBJECTIVE. A high proportion of children in the United States are overweight, suffer from food insecurity, and live in households facing maternal stressors. The objective of this article was to identify the associations of food insecurity and maternal stressors with childhood overweig Continue reading >>

Hypoglycemia In Children

Hypoglycemia In Children

What is hypoglycemia? Hypoglycemia occurs when the blood sugar is too low to fuel the brain and the body. Glucose is the main source of fuel for the body. The normal range of blood sugar, depending on the timing and nutritional content of the last meal consumed, is approximately 70 to 140 mg/dl (milligrams of glucose per deciliter of blood). If you have type 1 diabetes, your goal blood sugar range may be slightly different. Infants and small children with type 1 diabetes will have different goal ranges than adolescents or adults. However, consult your child's doctor for more specific information. Hypoglycemia may be a condition by itself, or may be a complication of diabetes or another disorder. Hypoglycemia is most often seen as a complication of overdoing insulin in a person with diabetes, which is sometimes referred to as an insulin reaction. What causes hypoglycemia? Causes of hypoglycemia in children with diabetes may include the following: Too much medication; for instance, too much insulin or oral diabetes medication Medication mistakes. All families will, at some point, give the wrong kind of insulin for a meal or at bedtime. Inaccurate blood-glucose readings A missed meal A delayed meal Too little food eaten, as compared to the amount of insulin taken More exercise than usual Diarrhea or vomiting Injury, illness, infection, or emotional stress Other medical problems sometimes seen in people with type 1 diabetes, such as celiac disease or an adrenal problem. An additional cause of hypoglycemia in neonates and toddlers includes a group of conditions called hyperinsulinism. This may occur as a result of abnormal cell development of the special "beta" cells in the pancreas that secrete insulin or from a mass in the pancreas. Hypoglycemia due to endogenous insulin i Continue reading >>

Chapter 363: Hypoglycemia

Any acutely ill child should be evaluated for hypoglycemia, especially when the history reveals diminished oral intake. Diagnosing hypoglycemia promptly is essential because low blood glucose levels that persist or recur may have catastrophic effects on the brain, particularly in infants. Accordingly, the primary care physician must recognize the clinical symptoms associated with hypoglycemia, document the low blood glucose level, and treat appropriately with glucose. Delineating the cause of the hypoglycemia is necessary to initiate effective continuing treatment. A child who has a serum or plasma glucose concentration less than 40 mg/dL or a whole blood glucose concentration less than 35 mg/dL should be investigated and treated for hypoglycemia; those who have plasma glucose concentrations between 40 and 50 mg/dL should be followed carefully.1 On the basis of observational data and expert opinion, the World Health Organization (WHO) currently provides different definitions for different specific clinical categories: newborns and infants with “signs of illness” (<45 mg/dL), healthy term or preterm newborns “feeding well” (<19.8 mg/dL), and infants and children with severe malnutrition (54 mg/dL).2 If hypoglycemia is suspected, then the blood glucose level may be approximated quickly at the bedside using a visual test strip or glucose meter and later confirmed by an appropriate chemical laboratory test. Although these thresholds have been commonly quoted and used, the level of plasma glucose that is safe is uncertain, and some authorities advocate a therapeutic goal of maintaining a plasma glucose level above 60 mg/dL in both neonates and older children to prevent permanent brain damage.3 Continue reading >>

Hypoglycemia in Infants and Children Authors: Robert A. Felter, MD, FAAP, CPE, FACPE, Professor of Clinical Pediatrics, Georgetown University School of Medicine; Assistant Director, Pediatric Inpatient and Emergency Service, Inova Loudoun Hospital, Leesburg, VA. Ron D.

Peer Reviewer: Ademola Adewale, MD, FAAEM, Assistant Professor of Emergency Medicine, Assistant Program Director, Florida Hospital Emergency Medicine Residency Program, Orlando, FL. Hypoglycemia is the most common metabolic disorder in children. The causes for hypoglycemia are many and diverse.1 One of the most frequent causes of hypoglycemia is insulin/glucose imbalance in diabetic children; since the management of diabetes and its complications is a subject on its own, this topic will not be included in this issue. The authors focus on issues important to the emergency physician, with emphasis on the need to diagnose and treat hypoglycemia quickly. In the very young infant, failure to recognize and treat hypoglycemia may lead to permanent neurological sequelae. It is also important to remember that hypoglycemia is a symptom and not a diagnosis or a disease entity and always has an underlying etiology that must be ascertained. Sometimes the emergency department (ED) physician may determine the underlying cause, and sometimes the symptom must be treated without knowing the underlying cause. Because hypoglycemia can be rapidly and easily determined at the bedside, there is little reason not to obtain this important piece of clinical information.

Approach To Hypoglycemia In Infants And Children

Approach To Hypoglycemia In Infants And Children

INTRODUCTION In healthy individuals, maintenance of a normal plasma glucose concentration depends upon: A normal endocrine system for integrating and modulating substrate mobilization, interconversion, and utilization. Functionally intact enzymes for glycogen synthesis, glycogenolysis, glycolysis, gluconeogenesis, and utilization of other metabolic fuels for oxidation and storage. An adequate supply of endogenous fat, glycogen, and potential gluconeogenic substrates (eg, amino acids, glycerol, and lactate). Adults are capable of maintaining a near-normal plasma glucose concentration, even when fasting for weeks or, in the case of obese subjects, months [1]. In contrast, healthy neonates and young children are unable to maintain normal plasma glucose concentrations after even a short fast (24 to 36 hours) and exhibit a progressive decline in plasma glucose concentration to hypoglycemic values [2,3].

Low Blood Sugar In Kids Linked To Mutations

Low Blood Sugar In Kids Linked To Mutations

WASHINGTON -- Children with recurrent unexplained episodes of hypoglycemia should be screened for the ketotic forms of glycogen storage disease, a researcher said here. Among a group of 173 children who had two or more episodes of ketotic hypoglycemia, defined as plasma glucose levels below 50 mg/dL and ketones present in the urine or blood, 34.7% were found on genetic testing to have mutations associated with disorders of glycogen storage or utilization, according to Michelle M. Corrado, BS, and colleagues from the University of Florida in Gainesville. Type 1, or "classical" glycogen storage disease, is caused by a genetic mutation which causes a deficiency of glucose-6-phosphatase. The result is an inability to metabolize glucose accompanied by a lack of gluconeogenesis, so patients become severely hypoglycemic and develop hepatomegaly. Certain other forms of the disease, however, are characterized by a milder phenotype. In types 3,6, and 9, the mutations prevent glycogen from breaking down into glucose, while in type zero, the mutation inhibits storage of glucose in the liver as glycogen. In those four types, patients can't utilize glucose for energy, but glyconeogenesis is intact and patients can break down fat for energy, with byproducts of triglycerides and ketones. Because little is known about the prevalence of these conditions, and to determine whether they might be an underrecognized cause of childhood hypoglycemia, Corrado's group has conducted a long-term study in which they screened genomic DNA from saliva of children with multiple episodes of hypoglycemia and no evidence of adrenal insufficiency, growth hormone deficiency, or fatty acid oxidation disorders. A total of 102 of the children enrolled in the study between 1998 and 2013 were male, and 71 were fe Continue reading >>

Clinical Practice Guidelines

Clinical Practice Guidelines

See also: Background to condition Clinical hypoglycemia is defined as a blood sugar level (BSL) low enough to cause symptoms and/or signs of impaired brain function. This is generally accepted as a BSL <2.6mmol/L. Prolonged or recurrent hypoglycaemia, especially when associated with symptoms and signs can cause long term neurological damage or death. Thus, prompt recognition and treatment are essential. Hypoglycaemia is the most frequent acute complication of type 1 diabetes either due to excess insulin or illnesses causing nausea, vomiting or diarrhoea and decreased oral intake. Hyperinsulinism is the most common cause of persistent hypoglycaemia under 2 years. The presence of ketonuria and/or ketonaemia makes this diagnosis very unlikely. Accelerated starvation (previously known as “ketotic hypoglycaemia”) is the most common cause of hypoglycemia beyond infancy, usually presenting between 18 months to 5 years. It occurs after a prolonged fast and is usually precipitated by a relatively mild illness. It requires documenting a low BSL in association with ketonuria and/or ketonaemia, but definitive diagnosis requires exclusion of other metabolic and endocrine causes. Hypoglycaemia may be an early manifestation of other serious disorders (eg. sepsis, congenital heart disease, tumours) Neonates – please refer to Neonatal Hypoglycemia Beyond neonatal period to 2 years: congenital hyperinsulinism, inborn errors of metabolism (eg. fatty acid oxidation defect, glycogen storage disease, galactosemia), congenital hormone deficiencies (eg. growth hormone deficiency) Child: accelerated starvation, hypopituitarism Adolescent: insulinoma, adrenal insufficiency Feeding history Tolerance to fasting / illness Relationship to food Milk products (galactosemia) Fructose e.g. juices Continue reading >>

Non-diabetic Hypoglycemia In Childhood

Non-diabetic Hypoglycemia In Childhood

WHAT YOU NEED TO KNOW: What is non-diabetic hypoglycemia? Non-diabetic hypoglycemia is a condition that causes your child's blood glucose (sugar) level to drop too low. This type of low blood sugar level can happen in children who do not have diabetes. When your child's blood sugar level drops too low, his brain cells and muscles do not have enough energy to work well. Glucose is also important for helping your child's brain grow normally. What causes non-diabetic hypoglycemia in children? The cause of non-diabetic hypoglycemia may be unknown. It may be caused by certain medical conditions. These include hyperinsulinism (your child's body makes too much insulin), hypothyroidism, or prediabetes. It may also be caused by fasting, which can lead to ketotic hypoglycemia. This is a condition that causes the body to change fats into glucose for energy. What are the signs and symptoms of non-diabetic hypoglycemia in children? Hunger or nausea Sweating more than usual Anxiety, confusion, or changes in behavior Fast heartbeat Weakness Blurred vision Dizziness or lightheadedness Headache How is non-diabetic hypoglycemia in children diagnosed? Healthcare providers will ask about your child's symptoms and your family's health. They may ask you about the amount of time between your child's last meal and the start of his symptoms. They may also ask if any other children in your family have hypoglycemia, or have had it in the past. Blood tests are done to measure your child's blood sugar levels. These tests may also be done to find the cause of your child's hypoglycemia. Fasting tests may be done. Healthcare providers watch your child closely during a period of time in which he does not eat. This test is done to see if, and when hypoglycemia occurs. An oral glucose tolerance test may Continue reading >>

An Often Overlooked Cause Of Vomiting

An Often Overlooked Cause Of Vomiting

Most parents don't realize that not getting enough food can be the cause of unexplained vomiting in the middle of the night or first thing in the morning. Where there is no fever, stomach flu, or any other common cause of vomiting in younger children, vomiting is often caused by low blood sugar. Most typically, this happens to children between 8 months and 4.5 to 5 years of age. The official diagnosis for this scenario is ketotic hypoglycemia. Vomiting induced by ketotic hypoglycemia usually happens in the middle of the night or first thing in the morning, and typically when there's been a longer-than-normal stretch of not eating - missing dinner is a common cause for those who are predisposed to this. The child will typically feel some nausea and/or abdominal discomfort just prior to vomiting, and will usually be subdued for about a half hour after vomiting, but will otherwise appear normal. Vomiting caused by ketotic hypoglycemia is often misdiagnosed as the stomach flu. The distinguishing feature of ketotic hypoglycemia is that the child quickly returns to normal; if vomiting occurs in the middle of the night, after a short period of malaise, the child will typically sleep comfortably for the rest of the night; if vomiting occurs first thing in the morning, within about 30 minutes, he or she will be ready to eat and go about everyday activities. Vomitus is typically bubbly and tinged with a bit of yellow color - this is distinctly different from vomitus that accompanies the stomach flu, which usually includes incompletely digested food. Normally during night-time sleep, the body uses blood glucose and some stores of glycogen in the muscles and/or liver to generate energy needed to carry out basic metabolic activities. Ketotic hypoglycemia tends to occur in young chil Continue reading >>

(rare Causes). Hypoglycemia And Ketotic Hypoglycaemia, January 2016

Information for parents and carers Hypoglycaemia (low blood sugar) and ketotic hypoglycaemia What is hypoglycaemia? Hypoglycemia is having a blood glucose (also known as blood sugar) level that is too low to provide energy for the body's cells. What is glucose? Glucose is a sugar that is made from the breakdown of carbohydrates found in foods. It is the main source of fuel for the body (including the brain). It may be stored in the liver and muscles for later use, but spare glucose is converted to fat. The level of glucose in the blood is controlled by complex hormone and energy pathways. What is a healthy range of blood glucose? The normal range of blood glucose throughout the day and night is around 3.5 – 6 mmols/litre. However, this varies according to a number of factors; your child’s doctor will talk with you about what should be a normal range for him or her. Why is hypoglycemia a concern? The brain depends on glucose, and too little can affect its ability to function. Severe or very prolonged hypoglycemia could result in fits or serious brain injury. We think your child may be at risk of low blood sugar and you will have been given some advice and treatment to prevent this problem. Causes in young children Single episodes: ï€ Sickness and diarrhoea, or another illness that may cause them to not eat enough. ï€ Fasting for a prolonged period of time. ï€ Prolonged exercise with lack of food. Recurrent episodes: ï€ Ketotic hypoglycaemia. ï€ Medications your child may be taking. ï€ Congenital (present at birth) error in energy metabolism or unusual hormone problem Hypoglycemia and ketotic hypoglycaemia What is ketotic hypoglycaemia? A common reason for recurrent episodes of low blood sugar in young children is ketotic hypoglycaemia, whi Continue reading >>

Hypoglycemia And Low Blood Sugar | Symptoms And Causes

What are the symptoms of hypoglycemia? While each child may experience symptoms of hypoglycemia differently, the most common include: shakiness dizziness sweating hunger headache irritability pale skin color sudden moodiness or behavior changes, such as crying for no apparent reason clumsy or jerky movements difficulty paying attention or confusion What causes hypoglycemia? The vast majority of episodes of hypoglycemia in children and adolescents occur when a child with diabetes takes too much insulin, eats too little, or exercises strenuously or for a prolonged period of time. For young children who do not have diabetes, hypoglycemia may be caused by: Single episodes: Stomach flu, or another illness that may cause them to not eat enough fasting for a prolonged period of time prolonged strenuous exercise and lack of food Recurrent episodes: accelerated starvation, also known as “ketotic hypoglycemia,” a tendency for children without diabetes, or any other known cause of hypoglycemia, to experience repeated hypoglycemic episodes. medications your child may be taking a congenital (present at birth) error in metabolism or unusual disorder such as hypopituitarism or hyperinsulinism.

Hypoglycemia

Hypoglycemia

Introduction Infants and children produce and use glucose at a higher turnover rate than adults, and are thus unable to maintain a normal plasma glucose concentration even after a short fast of 24-36 hours. In infants, 90% of the glucose is used by the brain, which decreases over time to reach the norm of 40% for adults. Thus, preventing hypoglycemia is very important to avoid developmental deficits. Definition of hypoglycemia <40 mg/dL, regardless of age. This definition is controversial, however, glucose levels below 40 mg/dL produces hunger and excessive catecholamine response. Symptoms Gen: Irritability, anxiety, hunger, fatigue, Neuro: HA, blurred vision, tremors, weakness, confusion, ataxia, stupor, seizures, coma GI: abdominal pain, Heme/CV: pallor, cyanosis, diaphoresis, tachycardia, Resp: tachypnea, lethargy, apnea Most symptoms can be explained through stimulation of sympathetic responses. Recurrent severe hypoglycemic episodes can lead to brain damage and intellectual impairment. History Age Dietary Intake: what types of food (carbohydrates, protein, etc), how soon after eating did hypoglycemia develop, amount of food intake Child’s PMHx Family History: sudden infant deaths, similar problems in family Evaluation of Suspected Hypoglycemia (note: if possible, collect these samples before treatment to offer chances of earlier diagnosis) Venous sample for glucose, BMP (electrolytes, BUN, Cr), LFTs, lactate, insulin level, C-peptide, growth hormone, and cortisol levels. Blood samples for substrates: FFAs, Beta-hydroxybutarate, total and free carnitine, acylcarnitines Immediately begin efforts to collect urine (bagged specimen) and send for urinalysis and urine organic acid analysis. Check urine for ketones and glucose. Differential for Hypoglycemia A good starti Continue reading >>
