Type 2 Diabetes
Print Overview Type 2 diabetes, once known as adult-onset or noninsulin-dependent diabetes, is a chronic condition that affects the way your body metabolizes sugar (glucose), your body's important source of fuel. With type 2 diabetes, your body either resists the effects of insulin — a hormone that regulates the movement of sugar into your cells — or doesn't produce enough insulin to maintain a normal glucose level. More common in adults, type 2 diabetes increasingly affects children as childhood obesity increases. There's no cure for type 2 diabetes, but you may be able to manage the condition by eating well, exercising and maintaining a healthy weight. If diet and exercise aren't enough to manage your blood sugar well, you also may need diabetes medications or insulin therapy. Symptoms Signs and symptoms of type 2 diabetes often develop slowly. In fact, you can have type 2 diabetes for years and not know it. Look for: Increased thirst and frequent urination. Excess sugar building up in your bloodstream causes fluid to be pulled from the tissues. This may leave you thirsty. As a result, you may drink — and urinate — more than usual. Increased hunger. Without enough insulin to move sugar into your cells, your muscles and organs become depleted of energy. This triggers intense hunger. Weight loss. Despite eating more than usual to relieve hunger, you may lose weight. Without the ability to metabolize glucose, the body uses alternative fuels stored in muscle and fat. Calories are lost as excess glucose is released in the urine. Fatigue. If your cells are deprived of sugar, you may become tired and irritable. Blurred vision. If your blood sugar is too high, fluid may be pulled from the lenses of your eyes. This may affect your ability to focus. Slow-healing sores o Continue reading >>
Insulin For Type 2 Diabetes: When, Why, And How
Blood sugar control is one of the most important parts of type 2 diabetes management. Although you may be able to treat the condition at first with oral medication and lifestyle changes, such as exercise and weight loss, most people with type 2 diabetes eventually need to take insulin by injection. "There are several scenarios in which insulin treatment should start, including in patients with significant hyperglycemia who are symptomatic," explained Alaleh Mazhari, DO, an associate professor of endocrinology at Loyola Medicine in Maywood, Illinois. "In these cases, the need for insulin may be short-term. Other situations include patients who are on multiple diabetic medications with uncontrolled diabetes, and uncontrolled diabetes in pregnancy, to name a few." Here's what you need to know about taking insulin in the short term and the long term. Insulin for Short-Term Blood Sugar Control Doctors use a blood test called a hemoglobin A1C test to measure average blood sugar control over a two- to three-month period. The treatment target for most people with diabetes is an A1C of 7 percent or less; those with higher levels may need a more intensive medication plan. "The American Association of Clinical Endocrinologists recommends starting a person with type 2 diabetes on insulin if their A1C is above 9 percent and they have symptoms," said Mazhari. Symptoms of type 2 diabetes include thirst, hunger, frequent urination, and weight loss. Research published in February 2013 in the journal The Lancet Diabetes & Endocrinology reviewed several studies that focused on the temporary use of insulin to restore sugar control in people with type 2 diabetes. The results showed that a two- to five-week course of short-term intensive insulin therapy (IIT) can induce remission in patients Continue reading >>

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 >>
Diabetes is a chronic disease that occurs because the body is unable to use blood sugar (glucose) properly. The exact cause of this malfunction is unknown, but genetic and environmental factors play a part. Risk factors for diabetes include obesity and high levels of cholesterol. Some specific causes are discussed below. Lack of insulin production This is primarily the cause of type 1 diabetes. It occurs when insulin-producing cells are damaged or destroyed and stop producing insulin. Insulin is needed to move blood sugar into cells throughout the body. The resulting insulin deficiency leaves too much sugar in the blood and not enough in the cells for energy. Insulin resistance This is specific to type 2 diabetes. It occurs when insulin is produced normally in the pancreas, but the body is still unable move glucose into the cells for fuel. At first, the pancreas will create more insulin to overcome the body’s resistance. Eventually the cells “wear out.” At that point the body slows insulin production, leaving too much glucose in the blood. This is known as prediabetes. A person with prediabetes has a blood sugar level higher than normal but not high enough for a diagnosis of diabetes. Unless tested, the person may not be aware, as there are no clear symptoms. Type 2 diabetes occurs as insulin production continues to decrease and resistance increases. Symptoms of insulin resistance » Genetics plays a role in determining how likely you are to develop some type of diabetes. Researchers don’t fully understand the role of genetics in the development of diabetes. According to the American Diabetes Association, statistics show that if you have a parent or sibling with diabetes, your odds of developing it yourself increase. Although research is not conclusive, some eth Continue reading >>
Diabetes Symptoms, (type 1 And Type 2)
Diabetes type 1 and type 2 definition and facts Diabetes is a chronic condition associated with abnormally high levels of sugar (glucose) in the blood. Insulin produced by the pancreas lowers blood glucose. Absence or insufficient production of insulin, or an inability of the body to properly use insulin causes diabetes. The two types of diabetes are referred to as type 1 and type 2. Former names for these conditions were insulin-dependent and non-insulin-dependent diabetes, or juvenile onset and adult onset diabetes. Symptoms of type 1 and type 2 diabetes include increased urine output, excessive thirst, weight loss, hunger, fatigue, skin problems slow healing wounds, yeast infections, and tingling or numbness in the feet or toes. Some of the risk factors for getting diabetes include being overweight or obese, leading a sedentary lifestyle, a family history of diabetes, hypertension (high blood pressure), and low levels of the "good" cholesterol (HDL) and elevated levels of triglycerides in the blood. If you think you may have prediabetes or diabetes contact a health-care professional. Diabetes mellitus is a group of metabolic diseases characterized by high blood sugar (glucose) levels that result from defects in insulin secretion, or its action, or both. Diabetes mellitus, commonly referred to as diabetes (as it will be in this article) was first identified as a disease associated with "sweet urine," and excessive muscle loss in the ancient world. Elevated levels of blood glucose (hyperglycemia) lead to spillage of glucose into the urine, hence the term sweet urine. Normally, blood glucose levels are tightly controlled by insulin, a hormone produced by the pancreas. Insulin lowers the blood glucose level. When the blood glucose elevates (for example, after eating food Continue reading >>
12 Myths About Insulin And Type 2 Diabetes
Insulin facts vs. fiction When you hear the word “insulin,” do you picture giant needles (ouch!) or pop culture portrayals of insulin users with low blood sugar (like Julia Roberts losing it in Steel Magnolias)? Either way, most people think of insulin as a difficult, painful, or potentially scary medical treatment. The problem is that if you have type 2 diabetes, you need to know the real deal before you can make an informed choice about whether or not this potentially lifesaving therapy is right for you. Here, we take a look at the facts and fiction about insulin when it comes to treating type 2 diabetes. Diabetics always need insulin Not necessarily. People with type 1 diabetes (about 5% to 10% of diabetics) do need insulin. If you have type 2, which includes 90% to 95% of all people with diabetes, you may not need insulin. Of adults with diabetes, only 14% use insulin, 13% use insulin and oral medication, 57% take oral medication only, and 16% control blood sugar with diet and exercise alone, according to the CDC. The point is to get blood sugar—which can be a highly toxic poison in the body—into the safe zone by any means necessary. Taking insulin means you’ve ‘failed’ “This is a big myth,” says Jill Crandall, MD, professor of clinical medicine and director of the diabetes clinical trial unit at the Albert Einstein College of Medicine, in the Bronx, N.Y. “Many people who try very hard to adhere to a diet, exercise, and lose weight will still need insulin.” The fact is that type 2 diabetes is a progressive illness, meaning that over time you may need to change what you do to make sure your blood sugar is in a healthy range. Eating right and exercise will always be important, but medication needs can vary. “A large percentage of people with ty Continue reading >>
The Causes Of Insulin Resistance In Type 1 Diabetes, Type 2 Diabetes And Prediabetes (video)
Most people believe that people with type 1 diabetes are not insulin resistant simply because they are not overweight. This could not be farther from the truth. While insulin resistance affects many overweight individuals, many people with type 1 diabetes remain skinny their entire lives despite a large degree of insulin resistance (1–3). Over the past decade, I have helped many people with type 1 diabetes measure, track and reverse insulin resistance. In practice, 100% of all my clients with type 1 diabetes suffer from insulin resistance despite the assumption that they were insulin sensitive. By measuring their baseline insulin resistance, we were able to identify an impaired ability to utilize glucose as a fuel, and through dedicated diet modification and frequent exercise, some of my clients have reduced their insulin usage by as much as 60%. If you have type 1 diabetes, do not be fooled into thinking that you are insulin sensitive simply because you are skinny. Insulin resistance is a hidden condition, and affects both normal weight and overweight individuals (1–3). What Causes Insulin Resistance? Insulin resistance underlies all forms of diabetes, and is a condition which primarily affects your muscles, liver and adipose tissue. Many people think that diabetes is caused by an excess intake of sugar and candy starting from a young age. While eating artificial sweeteners and drinking soda can certainly increase your risk for the development of insulin resistance and diabetes, in most cases diabetes is caused by excessive FAT intake. The most important thing you can do as a person with diabetes is understand the following: Diabetes is caused by a fat metabolism disorder, which results in a glucose metabolism disorder. At the heart of all forms of diabetes is insu Continue reading >>
Can Insulin Use Lead To Diabetes?
How common is the link between bodybuilders useind Insulin and going on to develop diabetes as a result of this. More importantly does anyone have first hand expierence of this or know of it happening? Is this a realistic possibility or likely or perhaps just a possibility tainted with a bit of scaremongering or over exagerating? I dont know of it happening to anyone and have seen people cycle with it for years, some combining it with every steroid cycle for over 10 years, most with HGH cycles since that has become popular. However I am concearned with the link so any opinions or expierence would be helpfull. Re:Can insulin use lead to diabetes? 2013/04/14 22:16:50( permalink ) ive hered plenty of people talking about it but have yet to see a person who has been effected like this or any studies to show this as true, would be interested to see some tho if anybody has links??

Diabetes Treatment: Using Insulin To Manage Blood Sugar
Understanding how insulin affects your blood sugar can help you better manage your condition. Insulin therapy is often an important part of diabetes treatment. Understand the key role insulin plays in managing your blood sugar, and the goals of insulin therapy. What you learn can help you prevent diabetes complications. The role of insulin in the body It may be easier to understand the importance of insulin therapy if you understand how insulin normally works in the body and what happens when you have diabetes. Regulate sugar in your bloodstream. The main job of insulin is to keep the level of glucose in the bloodstream within a normal range. After you eat, carbohydrates break down into glucose, a sugar that serves as a primary source of energy, and enters the bloodstream. Normally, the pancreas responds by producing insulin, which allows glucose to enter the tissues. Storage of excess glucose for energy. After you eat — when insulin levels are high — excess glucose is stored in the liver in the form of glycogen. Between meals — when insulin levels are low — the liver releases glycogen into the bloodstream in the form of glucose. This keeps blood sugar levels within a narrow range. If your pancreas secretes little or no insulin (type 1 diabetes), or your body doesn't produce enough insulin or has become resistant to insulin's action (type 2 diabetes), the level of glucose in your bloodstream increases because it's unable to enter cells. Left untreated, high blood glucose can lead to complications such as blindness, nerve damage (neuropathy) and kidney damage. The goals of insulin therapy If you have type 1 diabetes, insulin therapy replaces the insulin your body is unable to produce. Insulin therapy is sometimes needed for type 2 diabetes and gestational diabete Continue reading >>

What Is Insulin?
Insulin is a hormone made by the pancreas that allows your body to use sugar (glucose) from carbohydrates in the food that you eat for energy or to store glucose for future use. Insulin helps keeps your blood sugar level from getting too high (hyperglycemia) or too low (hypoglycemia). The cells in your body need sugar for energy. However, sugar cannot go into most of your cells directly. After you eat food and your blood sugar level rises, cells in your pancreas (known as beta cells) are signaled to release insulin into your bloodstream. Insulin then attaches to and signals cells to absorb sugar from the bloodstream. Insulin is often described as a “key,” which unlocks the cell to allow sugar to enter the cell and be used for energy. If you have more sugar in your body than it needs, insulin helps store the sugar in your liver and releases it when your blood sugar level is low or if you need more sugar, such as in between meals or during physical activity. Therefore, insulin helps balance out blood sugar levels and keeps them in a normal range. As blood sugar levels rise, the pancreas secretes more insulin. If your body does not produce enough insulin or your cells are resistant to the effects of insulin, you may develop hyperglycemia (high blood sugar), which can cause long-term complications if the blood sugar levels stay elevated for long periods of time. Insulin Treatment for Diabetes People with type 1 diabetes cannot make insulin because the beta cells in their pancreas are damaged or destroyed. Therefore, these people will need insulin injections to allow their body to process glucose and avoid complications from hyperglycemia. People with type 2 diabetes do not respond well or are resistant to insulin. They may need insulin shots to help them better process Continue reading >>
What Does Insulin Do?
The word “insulin” can instill fear in many people who have or who are at risk for diabetes. Some of the beliefs around insulin are that if you have to take it, you’ll go blind or lose a limb. Or that insulin causes you to gain weight. Or that it means your diabetes is worsening. While these beliefs are understandable, the reality is that they’re not true. In fact, insulin is a life-saving medication: without it, people with Type 1 diabetes wouldn’t be alive, and many people with Type 2 diabetes would be struggling. The discovery of insulin is so important that it’s often called one of the greatest medical developments of the 20th century. This week, let’s delve into insulin and learn more about how truly amazing it is! What exactly is insulin? Insulin is a hormone. It’s made in the beta cells of the pancreas, and one of its main roles is to help regulate, or control, your blood sugar. When there’s enough insulin in the body, it helps to keep your blood sugar from going too high. In people who don’t have diabetes, blood sugars are very carefully and tightly controlled, staying within a safe and healthy range. After a person without diabetes eats a meal or a snack, the pancreas releases insulin. The insulin then signals muscle, fat, and liver cells in the body to absorb glucose (sugar) from the bloodstream to be used for energy. In this sense, insulin is like a key that unlocks the doors of the cells to allow glucose to enter. You can also think of insulin as a “storage” hormone, since when there’s more glucose than the body needs, insulin helps the body store that excess glucose in the liver to be used at a later time. Insulin also signals the liver to stop releasing glucose into the bloodstream. Insulin also helps shuttle amino acids (from pro Continue reading >>

Facts About Diabetes And Insulin
Diabetes is a very common disease, which, if not treated, can be very dangerous. There are two types of diabetes. They were once called juvenile-onset diabetes and adult diabetes. However, today we know that all ages can get both types so they are simply called type 1 and type 2 diabetes. Type 1, which occurs in approximately 10 percent of all cases, is an autoimmune disease in which the immune system, by mistake, attacks its own insulin-producing cells so that insufficient amounts of insulin are produced - or no insulin at all. Type 1 affects predominantly young people and usually makes its debut before the age of 30, and most frequently between the ages of 10 and 14. Type 2, which makes up the remaining 90 percent of diabetes cases, commonly affects patients during the second half of their lives. The cells of the body no longer react to insulin as they should. This is called insulin resistance. In the early 1920s, Frederick Banting, John Macleod, George Best and Bertram Collip isolated the hormone insulin and purified it so that it could be administered to humans. This was a major breakthrough in the treatment of diabetes type 1. Insulin Insulin is a hormone. Hormones are chemical substances that regulate the cells of the body and are produced by special glands. The hormone insulin is a main regulator of the glucose (sugar) levels in the blood. Insulin is produced in the pancreas. To be more specific, it's produced by the beta cells in the islets of Langerhans in the pancreas. When we eat, glucose levels rise, and insulin is released into the bloodstream. The insulin acts like a key, opening up cells so they can take in the sugar and use it as an energy source. Sugar is one of the top energy sources for the body. The body gets it in many forms, but mainly as carbohydr Continue reading >>
Type 1 Diabetes
Type 1 diabetes can occur at any age. It is most often diagnosed in children, adolescents, or young adults. Insulin is a hormone produced in the pancreas by special cells, called beta cells. The pancreas is below and behind the stomach. Insulin is needed to move blood sugar (glucose) into cells. Inside the cells, glucose is stored and later used for energy. With type 1 diabetes, beta cells produce little or no insulin. Without enough insulin, glucose builds up in the bloodstream instead of going into the cells. This buildup of glucose in the blood is called hyperglycemia. The body is unable to use the glucose for energy. This leads to the symptoms of type 1 diabetes. The exact cause of type 1 diabetes is unknown. Most likely, it is an autoimmune disorder. This is a condition that occurs when the immune system mistakenly attacks and destroys healthy body tissue. With type 1 diabetes, an infection or another trigger causes the body to mistakenly attack the cells in the pancreas that make insulin. The tendency to develop autoimmune diseases, including type 1 diabetes, can be passed down through families. Continue reading >>
High Blood Sugar Faqs
Find possible causes and solutions for high blood sugar here. Some common causes include: In this section, you will find: Why am I having high blood sugars? Possible causes include: Incorrect carbohydrate counting If your mealtime carbohydrate count is wrong, your insulin dose will be incorrect as well. This is particularly true when eating out or when eating foods that don’t have nutrition labels. The solution: Learn more about carbohydrate counting. Weigh and measure your food whenever possible. Eat foods with carbohydrate counts that you already know. Research nutrition information online for food options at restaurants and chain outlets. “Out-eating” the insulin It’s not always easy to anticipate how much you will actually eat during a meal. However, missing the mark has the same effect as if you miscounted carbohydrates. Moreover, there are individual limits on how much mealtime carbohydrate can realistically be covered. The solution: If you decide to eat more than you planned, you will need to take more insulin to cover the additional carbohydrates. In general it’s wise to limit your mealtime consumption of carbohydrate to less than 60-75g or to whatever has been recommended by your nutritionist. If you have a special occasion coming up, be sure to discuss any special “party meal” or “banquet” medication dose adjustment with your medical provider. Insufficient insulin coverage of the carbohydrate (ie Inadequate insulin-to-carbohydrate ratio) It is important to know how many grams of carbohydrate are covered by one unit of insulin – this is your insulin-to-carbohydrate ratio. If you think the ratio is out of balance, ask yourself these questions. Did you count the carbohydrates correctly? Did you take the proper blood sugar correction dose befor Continue reading >>
Diabetes And Inflammation
Inactivity and obesity increase the risk for diabetes, but exactly how is unclear. Recent research suggests that inflammation inside the body plays a role in the development of type 2 diabetes. The good news: An "anti-inflammatory" diet and exercise plan can help prevent and treat type 2 diabetes. The effects of inflammation are familiar to anyone who has experienced a bug bite, rash, skin infection, or ankle sprain. In those situations, you will see swelling in the affected area. With type 2 diabetes, inflammation is internal. People with type 2 diabetes don't produce enough insulin or their bodies can't use the insulin adequately. Insulin is a hormone that is made by cells in the pancreas. It controls the amount of sugar in the blood. Insulin may also have an impact on tissue in the body. Its effects on tissue are influenced by many factors, including obesity and the accumulation of fat around the belly and on major organs in the abdomen. The fat cells can produce chemicals that lead to inflammation. Scientists are only beginning to understand the role this form of internal inflammation may play in the development of chronic diseases like diabetes. Decades ago, researchers identified higher levels of inflammation in the bodies of people with type 2 diabetes. The levels of certain inflammatory chemicals called cytokines are often higher in people with type 2 diabetes compared to people without diabetes. Obesity and inactivity have long been known to be the most important risk factors that drive the development of type 2 diabetes. How could carrying extra weight and sofa-sitting be connected to higher levels of inflammatory chemicals in the body and the development of diabetes? Researchers discovered that in people with type 2 diabetes, cytokine levels are elevated insi Continue reading >>
