Diabetes: What's True And False?
en espaolLa diabetes: Qu es cierto y qu es falso? If you're like most people with diabetes, you'll get all kinds of advice about it from friends and family or online. Some of this information is wrong. Here's the truth about some of the common things you might hear. Does eating too much sugar cause diabetes? No. Type 1 diabetes happens when cells in the pancreas that make insulin are destroyed. This happens because something goes wrong with the body's immune system . It has nothing to do with how much sugar a person eats. Sugar doesn't cause diabetes. But there is one way that sugar can influence whether a person gets type 2 diabetes. Consuming too much sugar (or sugary foods and drinks) can make people put on weight. Gaining too much weight leads to type 2 diabetes in some people. Of course, eating too much sugar isn't the only cause of weight gain. Weight gain from eating too much of any food can make a person's chance of getting diabetes greater. Yes! You can have your cake and eat it too, just not the whole cake! Like everyone, people with diabetes should put the brakes on eating too many sweets. But you can still enjoy them sometimes. People with type 1 diabetes don't grow out of it. With type 1 diabetes, the pancreas stops making insulin and won't make it again. People with type 1 diabetes will always need to take insulin, at least until scientists find a cure. People with type 2 diabetes will always have a tendency to get high blood sugar levels. But if they take steps to live a healthier life, it can sometimes lower their blood sugar. If people eat healthy foods and exercise enough to get their blood sugar levels back on track, doctors might say they can stop taking insulin or other medicines. Can you catch diabetes from a person who has it? No. Diabetes is not Continue reading >>
What Is Diabetes?
Diabetes is an incurable condition in which the body cannot control blood sugar levels, because of problems with the hormone insulin. There are two main variations of the illness, Type I and Type II. How does the body control blood sugar levels? Your body uses blood sugar (glucose) for energy. Glucose is a basic ingredient of sweet foods such as sweets and cakes. It can also be produced by carbohydrates such as potatoes, pasta or bread when they are digested and broken down. Under normal circumstances, the hormone insulin, which is made by your pancreas, carefully regulates how much glucose is in the blood. Insulin stimulates cells all over your body to absorb enough glucose from the blood to provide the energy, or fuel, that they need. After a meal, the amount of glucose in your blood rises, which triggers the release of insulin. When blood glucose levels fall, during exercise for example, insulin levels fall too. Types of diabetes There are two main types of diabetes. In Type 1 diabetes the cells of the pancreas stop making insulin. In Type 2 diabetes, either the pancreas cells do not make enough insulin, or the body's cells do not react properly to it. This is known as insulin resistance. Type 1 diabetes is an autoimmune condition, and the immune system attacks the cells of the pancreas. It tends to affect people before the age of 40, and often follows a trigger such as a viral infection. The exact mechanisms that lead to Type 2 diabetes are not fully understood, but an underlying genetic susceptibility is usually present. This could be a family history of the illness, for example. The condition is then triggered by lifestyle factors - such as obesity - and it usually appears in people over the age of 40. There are three other, less common, forms of diabetes: Gestati Continue reading >>

Controlling Blood Sugar In Diabetes: How Low Should You Go?
Diabetes is an ancient disease, but the first effective drug therapy was not available until 1922, when insulin revolutionized the management of the disorder. Insulin is administered by injection, but treatment took another great leap forward in 1956, when the first oral diabetic drug was introduced. Since then, dozens of new medications have been developed, but scientists are still learning how best to use them. And new studies are prompting doctors to re-examine a fundamental therapeutic question: what level of blood sugar is best? Normal metabolism To understand diabetes, you should first understand how your body handles glucose, the sugar that fuels your metabolism. After you eat, your digestive tract breaks down carbohydrates into simple sugars that are small enough to be absorbed into your bloodstream. Glucose is far and away the most important of these sugars, and it's an indispensable source of energy for your body's cells. But to provide that energy, it must travel from your blood into your cells. Insulin is the hormone that unlocks the door to your cells. When your blood glucose levels rise after a meal, the beta cells of your pancreas spring into action, pouring insulin into your blood. If you produce enough insulin and your cells respond normally, your blood sugar level drops as glucose enters the cells, where it is burned for energy or stored for future use in your liver as glycogen. Insulin also helps your body turn amino acids into proteins and fatty acids into body fat. The net effect is to allow your body to turn food into energy and to store excess energy to keep your engine running if fuel becomes scarce in the future. A diabetes primer Diabetes is a single name for a group of disorders. All forms of the disease develop when the pancreas is unable to Continue reading >>
Must Read Articles Related To High Blood Sugar (hyperglycemia)
A A A High Blood Sugar (Hyperglycemia) Whenever the glucose (sugar) level in one's blood rises high temporarily, this condition is known as hyperglycemia. The opposite condition, low blood sugar, is called hypoglycemia. Glucose comes from most foods, and the body uses other chemicals to create glucose in the liver and muscles. The blood carries glucose (blood sugar) to all the cells in the body. To carry glucose into the cells as an energy supply, cells need help from insulin. Insulin is a hormone made by the pancreas, an organ near the stomach. The pancreas releases insulin into the blood, based upon the blood sugar level. Insulin helps move glucose from digested food into cells. Sometimes, the body stops making insulin (as in type 1 diabetes), or the insulin does not work properly (as in type 2 diabetes). In diabetic patients, glucose does not enter the cells sufficiently, thus staying in the blood and creating high blood sugar levels. Blood sugar levels can be measured in seconds by using a blood glucose meter, also known as a glucometer. A tiny drop of blood from the finger or forearm is placed on a test strip and inserted into the glucometer. The blood sugar (or glucose) level is displayed digitally within seconds. Blood glucose levels vary widely throughout the day and night in people with diabetes. Ideally, blood glucose levels range from 90 to 130 mg/dL before meals, and below 180 mg/dL within 1 to 2 hours after a meal. Adolescents and adults with diabetes strive to keep their blood sugar levels within a controlled range, usually 80-150 mg/dL before meals. Doctors and diabetes health educators guide each patient to determine their optimal range of blood glucose control. When blood sugar levels remain high for several hours, dehydration and more serious complicat Continue reading >>
15 Ways High Blood Sugar Affects Your Body
High blood sugar symptoms Glucose, or sugar, is the fuel that powers cells throughout the body. Blood levels of this energy source ebb and flow naturally, depending what you eat (and how much), as well as when you eat it. But when something goes wrong—and cells aren't absorbing the glucose—the resulting high blood sugar damages nerves, blood vessels, and organs, setting the stage for dangerous complications. Normal blood-sugar readings typically fall between 60 mg/dl and 140 mg/dl. A blood test called a hemoglobin A1c measures average blood sugar levels over the previous three months. A normal reading is below 5.7% for people without diabetes. An excess of glucose in the bloodstream, or hyperglycemia, is a sign of diabetes. People with type 1 diabetes don’t make insulin, the hormone needed to ferry sugar from the bloodstream into cells. Type 2 diabetes means your body doesn’t use insulin properly and you can end up with too much or too little insulin. Either way, without proper treatment, toxic amounts of sugar can build up in the bloodstream, wreaking havoc head to toe. That’s why it’s so important to get your blood sugar levels in check. “If you keep glucose levels near normal, you reduce the risk of diabetes complications,” says Robert Ratner, MD, chief scientific and medical officer of the American Diabetes Association. Here’s a rundown of the major complications and symptoms of high blood sugar. No symptoms at all Often, high blood sugar causes no (obvious) symptoms at all, at least at first. About 29 million people in the U.S. have diabetes, but one in four has no idea. Another 86 million have higher-than-normal blood sugar levels, but not high enough to be diagnosed with type 2 diabetes. That's why it’s a good idea to get your blood sugar test Continue reading >>
Diabetes mellitus, disorder of carbohydrate metabolism characterized by impaired ability of the body to produce or respond to insulin and thereby maintain proper levels of sugar (glucose) in the blood. Diabetes is a major cause of morbidity and mortality, though these outcomes are not due to the immediate effects of the disorder. They are instead related to the diseases that develop as a result of chronic diabetes mellitus. These include diseases of large blood vessels (macrovascular disease, including coronary heart disease and peripheral arterial disease) and small blood vessels (microvascular disease, including retinal and renal vascular disease), as well as diseases of the nerves. Causes and types Insulin is a hormone secreted by beta cells, which are located within clusters of cells in the pancreas called the islets of Langerhans. Insulin’s role in the body is to trigger cells to take up glucose so that the cells can use this energy-yielding sugar. Patients with diabetes may have dysfunctional beta cells, resulting in decreased insulin secretion, or their muscle and adipose cells may be resistant to the effects of insulin, resulting in a decreased ability of these cells to take up and metabolize glucose. In both cases, the levels of glucose in the blood increase, causing hyperglycemia (high blood sugar). As glucose accumulates in the blood, excess levels of this sugar are excreted in the urine. Because of greater amounts of glucose in the urine, more water is excreted with it, causing an increase in urinary volume and frequency of urination as well as thirst. (The name diabetes mellitus refers to these symptoms: diabetes, from the Greek diabainein, meaning “to pass through,” describes the copious urination, and mellitus, from the Latin meaning “sweetened wi Continue reading >>
Type 2 Diabetes: What Is It?
When it comes to your body, you probably spend more time thinking about your hair than your hormones. For some people, though, a problem with a hormone called insulin causes a health condition called type 2 diabetes (pronounced: dye-uh-BEE-tees). Diabetes is a disease that affects how the body uses glucose (pronounced: GLOO-kose), a sugar that is the body's main source of fuel. Your body needs glucose to keep running. Here's how it should work: Glucose from the food gets into your bloodstream. Your pancreas makes a hormone called insulin (pronounced: IN-suh-lin). Insulin helps the glucose get into the body's cells. The pancreas is a long, flat gland in your belly that helps your body digest food. It also makes insulin. Insulin is like a key that opens the doors to the cells of the body. It lets the glucose in. Then the glucose can move out of the blood and into the cells. But if someone has diabetes, either the body can't make insulin or the insulin doesn't work in the body like it should. The glucose can't get into the cells normally, so the blood sugar level gets too high. Lots of sugar in the blood makes people sick if they don't get treatment. There are two major types of diabetes: type 1 and type 2. Each type causes high blood sugar levels in a different way. In type 1 diabetes , the pancreas can't make insulin. The body can still get glucose from food, but the glucose can't get into the cells, where it's needed, and glucose stays in the blood. This makes the blood sugar level very high. With type 2 diabetes, the body still makes insulin. But a person with type 2 diabetes doesn't respond normally to the insulin the body makes. So glucose is less able to enter the cells and do its job of supplying energy. When glucose can't enter the cells in this way, doctors call Continue reading >>
Print Symptoms of type 1 diabetes often appear suddenly and are often the reason for checking blood sugar levels. Because symptoms of other types of diabetes and prediabetes come on more gradually or may not be evident, the American Diabetes Association (ADA) has recommended screening guidelines. The ADA recommends that the following people be screened for diabetes: Anyone with a body mass index higher than 25, regardless of age, who has additional risk factors, such as high blood pressure, a sedentary lifestyle, a history of polycystic ovary syndrome, having delivered a baby who weighed more than 9 pounds, a history of diabetes in pregnancy, high cholesterol levels, a history of heart disease, and having a close relative with diabetes. Anyone older than age 45 is advised to receive an initial blood sugar screening, and then, if the results are normal, to be screened every three years thereafter. Tests for type 1 and type 2 diabetes and prediabetes Glycated hemoglobin (A1C) test. This blood test indicates your average blood sugar level for the past two to three months. It measures the percentage of blood sugar attached to hemoglobin, the oxygen-carrying protein in red blood cells. The higher your blood sugar levels, the more hemoglobin you'll have with sugar attached. An A1C level of 6.5 percent or higher on two separate tests indicates that you have diabetes. An A1C between 5.7 and 6.4 percent indicates prediabetes. Below 5.7 is considered normal. If the A1C test results aren't consistent, the test isn't available, or if you have certain conditions that can make the A1C test inaccurate — such as if you're pregnant or have an uncommon form of hemoglobin (known as a hemoglobin variant) — your doctor may use the following tests to diagnose diabetes: Random blood sugar Continue reading >>
Blood Sugar Or Blood Glucose: What Does It Do?
Blood sugar, or blood glucose, is sugar that the bloodstream carries to all the cells in the body to supply energy. Blood sugar or blood glucose measurements represent the amount of sugar being transported in the blood during one instant. The sugar comes from the food we eat. The human body regulates blood glucose levels so that they are neither too high nor too low. The blood's internal environment must remain stable for the body to function. This balance is known as homeostasis. The sugar in the blood is not the same as sucrose, the sugar in the sugar bowl. There are different kinds of sugar. Sugar in the blood is known as glucose. Blood glucose levels change throughout the day. After eating, levels rise and then settle down after about an hour. They are at their lowest point before the first meal of the day, which is normally breakfast. How does sugar get into the body's cells? When we eat carbohydrates, such as sugar, or sucrose, our body digests it into glucose, a simple sugar that can easily convert to energy. The human digestive system breaks down carbohydrates from food into various sugar molecules. One of these sugars is glucose, the body's main source of energy. The glucose goes straight from the digestive system into the bloodstream after food is consumed and digested. But glucose can only enter cells if there is insulin in the bloodstream too. Without insulin, the cells would starve. After we eat, blood sugar concentrations rise. The pancreas releases insulin automatically so that the glucose enters cells. As more and more cells receive glucose, blood sugar levels return to normal again. Excess glucose is stored as glycogen, or stored glucose, in the liver and the muscles. Glycogen plays an important role in homeostasis, because it helps our body function du Continue reading >>

Blood Sugar Level
The fluctuation of blood sugar (red) and the sugar-lowering hormone insulin (blue) in humans during the course of a day with three meals. One of the effects of a sugar-rich vs a starch-rich meal is highlighted. The blood sugar level, blood sugar concentration, or blood glucose level is the amount of glucose present in the blood of humans and other animals. Glucose is a simple sugar and approximately 4 grams of glucose are present in the blood of humans at all times. The body tightly regulates blood glucose levels as a part of metabolic homeostasis. Glucose is stored in skeletal muscle and liver cells in the form of glycogen; in fasted individuals, blood glucose is maintained at a constant level at the expense of glycogen stores in the liver and skeletal muscle. In humans, glucose is the primary source of energy, and is critical for normal function, in a number of tissues, particularly the human brain which consumes approximately 60% of blood glucose in fasted, sedentary individuals. Glucose can be transported from the intestines or liver to other tissues in the body via the bloodstream. Cellular glucose uptake is primarily regulated by insulin, a hormone produced in the pancreas. Glucose levels are usually lowest in the morning, before the first meal of the day, and rise after meals for an hour or two by a few millimoles. Blood sugar levels outside the normal range may be an indicator of a medical condition. A persistently high level is referred to as hyperglycemia; low levels are referred to as hypoglycemia. Diabetes mellitus is characterized by persistent hyperglycemia from any of several causes, and is the most prominent disease related to failure of blood sugar regulation. There are different methods of testing and measuring blood sugar le Continue reading >>
How Does Eating Affect Your Blood Sugar?
Part 1 of 8 What is blood sugar? Blood sugar, also known as blood glucose, comes from the food you eat. Your body creates blood sugar by digesting some food into a sugar that circulates in your bloodstream. Blood sugar is used for energy. The sugar that isn’t needed to fuel your body right away gets stored in cells for later use. Too much sugar in your blood can be harmful. Type 2 diabetes is a disease that is characterized by having higher levels of blood sugar than what is considered within normal limits. Unmanaged diabetes can lead to problems with your heart, kidneys, eyes, and blood vessels. The more you know about how eating affects blood sugar, the better you can protect yourself against diabetes. If you already have diabetes, it’s important to know how eating affects blood sugar. Part 2 of 8 Your body breaks down everything you eat and absorbs the food in its different parts. These parts include: carbohydrates proteins fats vitamins and other nutrients The carbohydrates you consume turn into blood sugar. The more carbohydrates you eat, the higher the levels of sugar you will have released as you digest and absorb your food. Carbohydrates in liquid form consumed by themselves are absorbed more quickly than those in solid food. So having a soda will cause a faster rise in your blood sugar levels than eating a slice of pizza. Fiber is one component of carbohydrates that isn’t converted into sugar. This is because it can’t be digested. Fiber is important for health, though. Protein, fat, water, vitamins, and minerals don’t contain carbohydrates. These components won’t affect your blood sugar levels. If you have diabetes, your carbohydrate intake is the most important part of your diet to consider when it comes to managing your blood sugar levels. Part 3 Continue reading >>
What Is Diabetes Mellitus?
Diabetes mellitus is a common disease where there is too much sugar (glucose) floating around in your blood. This occurs because either the pancreas can’t produce enough insulin or the cells in your body have become resistant to insulin. When you eat food, the amount of glucose in your blood skyrockets. That’s because the food you eat is converted into glucose (usable energy for your cells) and enters your blood to be transported to your cells around the body. Special cells in your pancreas sense the increase of glucose and release insulin into your blood. Insulin has a lot of different jobs, but one of its main tasks is to help decrease blood glucose levels. It does this by activating a system which transports glucose from your blood into your cells. It also decreases blood glucose by stimulating an enzyme called glycogen synthase in the liver. This molecule is responsible for making glycogen, a long string of glucose, which is then stored in the liver and used in the future when there is a period of low blood glucose. As insulin works on your body, the amount of glucose in the blood slowly returns to the same level it was before you ate.. This glucose level when you haven’t eaten recently (called fasting glucose) sits around 3.5-6 mmol/L (70-110 mg/dL). Just after a meal, your blood glucose can jump as high as 7.8mmol/L (140 mg/dL) depending on how much and what you ate. There are two types of diabetes mellitus, type 1 and type 2. In both types, your body has trouble transporting sugar from your blood into your cells. This leads to high levels of glucose in your blood and a deficiency of glucose in your cells. The main difference between type 1 and type 2 diabetes mellitus is the underlying mechanisms that cause your blood sugar to stray from the normal range. T Continue reading >>
How Blood Sugar Affects Your Body
When you have diabetes, your blood sugar (glucose) levels may be consistently high. Over time, this can damage your body and lead to many other problems. How much sugar in the blood is too much? And why is high glucose so bad for you? Here’s a look at how your levels affect your health. They're less than 100 mg/dL after not eating (fasting) for at least 8 hours. And they're less than 140 mg/dL 2 hours after eating. During the day, levels tend to be at their lowest just before meals. For most people without diabetes, blood sugar levels before meals hover around 70 to 80 mg/dL. For some people, 60 is normal; for others, 90. What's a low sugar level? It varies widely, too. Many people's glucose won't ever fall below 60, even with prolonged fasting. When you diet or fast, the liver keeps your levels normal by turning fat and muscle into sugar. A few people's levels may fall somewhat lower. Doctors use these tests to find out if you have diabetes: Fasting plasma glucose test. The doctor tests your blood sugar levels after fasting for 8 hours and it’s higher than 126 mg/dL. Oral glucose tolerance test. After fasting for 8 hours, you get a special sugary drink. Two hours later your sugar level is higher than 200. Random check. The doctor tests your blood sugar and it’s higher than 200, plus you’re peeing more, always thirsty, and you’ve gained or lost a significant amount of weight. He’ll then do a fasting sugar level test or an oral glucose tolerance test to confirm the diagnosis. Any sugar levels higher than normal are unhealthy. Levels that are higher than normal, but not reaching the point of full-blown diabetes, are called prediabetes. According to the American Diabetes Association, 86 million people in the U.S. have this condition, which can lead to diabetes Continue reading >>
Blood Sugar Levels & Ranges (low, Normal & High)
Normal sugar ranges or levels, mean the normal range of concentrations blood glucose levels (sugar) that occur in the blood measured by a test. Values that are below or above the range of values considered "normal" are abnormal. either too high or two low ( hypoglycemia and hypercyglycemia). Diabetes is defined as a disease in which the body has an impaired ability to either produce or respond to the hormone insulin . People with type 1 diabetes have a pancreas that does not make insulin. People with type 2 diabetes have cells in the body that are resistant to insulin or have a pancreas that slows or stops producing adequate insulin levels (blood glucose). Both types of diabetes can result in abnormal glucose levels. Normal blood levels may range slightly depending on what blood tests are used, and your doctor may have, but the variances are small. In addition, what are normal ranges for nondiabetics are not the same for diabetics; it is generally accepted that target blood sugar measurements for people with diabetes will be slightly higher than those without diabetes. A person who is does not have a normal glucose range of 72-99mg/dL while fasting and up to 140mg/dL about 2 hours after eating. People with diabetes who have well-controlled glucose levels with medications have a different target glucose range. These people may have a fasting range of about 100 mg/dL or less and 180mg/dL about 2 hours after eating. If a persons diabetes is not well controlled, the person may have much higher glucose ranges or hypoglycemia (for example, 200 -400 mg/d; however some people with diabetes have blood sugar levels that are much higher. Symptoms, Signs, Causes, of Levels of High Blood Sugar In the Blood High blood sugar or hyperglycemia is an abnormally high blood sugar (blood g Continue reading >>
Know Your Blood Sugar Numbers: Use Them To Manage Your Diabetes
Checking your blood sugar, also called blood glucose, is an important part of diabetes care. This tip sheet tells you: why it helps you to know your blood sugar numbers how to check your blood sugar levels what are target blood sugar levels what to do if your levels are too low or too high how to pay for these tests Why do I need to know my blood sugar numbers? Your blood sugar numbers show how well your diabetes is managed. And managing your diabetes means that you have less chance of having serious health problems, such as kidney disease and vision loss. As you check your blood sugar, you can see what makes your numbers go up and down. For example, you may see that when you are stressed or eat certain foods, your numbers go up. And, you may see that when you take your medicine and are active, your numbers go down. This information lets you know what is working for you and what needs to change. How is blood sugar measured? There are two ways to measure blood sugar. Blood sugar checks that you do yourself. These tell you what your blood sugar level is at the time you test. The A1C (A-one-C) is a test done in a lab or at your provider’s office. This test tells you your average blood sugar level over the past 2 to 3 months. How do I check my blood sugar? You use a blood glucose meter to check your blood sugar. This device uses a small drop of blood from your finger to measure your blood sugar level. You can get the meter and supplies in a drug store or by mail. Read the directions that come with your meter to learn how to check your blood sugar. Your health care team also can show you how to use your meter. Write the date, time, and result of the test in your blood sugar record.
