What Is Type 1 Diabetes And Why Does It Occur?
There are two main types of diabetes, known as "Type 1 Diabetes" and "Type 2 Diabetes". These two conditions are generally considered to be 2 different and separate conditions, so it is important to understand the differences between the two. Some old names for Type 1 Diabetes include: "Juvenile Diabetes", "Insulin dependent diabetes mellitus" and "IDDM". These old names should not be used, as they are no longer considered correct. Important Stuff to Know In our bodies, an organ known as the pancreas produces insulin, which is a very important hormone. Insulin is vital because it enables the metabolism of carbohydrates, fats and proteins. We need insulin to survive. In Type 1 diabetes, the immune system attacks the insulin producing beta cells in the pancreas. This usually happens in younger people, but it can happen at any age. When this happens, the pancreas no longer produces insulin. So what happens if there is no insulin in your body? The main effect is high blood sugar (hyperglycaemia). Insulin normally moves blood sugar into body tissues where it is used for energy. When there is no insulin, sugar builds up in the blood. High blood sugar is dangerous, with many side effects. It also causes damage to the body. What are the symptoms of Type 1 diabetes? The symptoms of Type 1 diabetes are all based on the fact that there is high blood sugar. The symptoms include: Extreme thirst Frequent urination Lethargy, fatigue and drowsiness Blurred vision Sudden weight loss Increased appetite, hunger When the blood sugar is stabilised by treatment, these symptoms go away. How is Type 1 diabetes treated? Every person with Type 1 diabetes needs to inject themselves with insulin to survive. There are quite a number of different types of insulin, and a number of different insulin t Continue reading >>
Type 1 And Type 2 Diabetes: What’s The Difference?
If your child or someone you know has been recently diagnosed with type 1 diabetes, you may be wondering how the disease differs from type 2 diabetes — the form people tend to know more about. What causes type 1 versus type 2 diabetes? Are the symptoms the same? And how is each treated? Here to clear up the confusion with an overview of key differences — and similarities — between these two types of diabetes are experts Julie Settles, M.S.N., A.C.N.P.-B.C., C.E.N., a clinical research scientist at Lilly Diabetes, and Rosemary Briars, N.D., P.N.P.-B.C., C.D.E., C.C.D.C., clinical director and program co-director of the Chicago Children’s Diabetes Center at La Rabida Children’s Hospital. Causes Diabetes, or diabetes mellitus, as it’s formally known in medical terms, describes a group of metabolic diseases in which a person develops high blood glucose (blood sugar). The underlying health factors causing the high blood sugar will determine whether someone is diagnosed with type 1 or type 2 diabetes. Type 1 diabetes is an autoimmune disease in which “the body’s immune system starts to make antibodies that are targeted directly at the insulin-producing cells of the pancreas (islet cells),” explains Briars. Over time, the immune system “gradually destroys the islet cells, so insulin is no longer made and the person has to take insulin every day, from then on,” she says. As for why this happens, Settles notes, “The immune system normally fights off viruses and bacteria that we do not want in our body, but when it causes diabetes, it is because something has gone wrong and now the body attacks its own cells.” Triggering this autoimmune response is a complex mix of genetic and environmental factors that researchers are still trying to fully understand.

Type 1 Diabetes
Print Overview Type 1 diabetes, once known as juvenile diabetes or insulin-dependent diabetes, is a chronic condition in which the pancreas produces little or no insulin. Insulin is a hormone needed to allow sugar (glucose) to enter cells to produce energy. Different factors, including genetics and some viruses, may contribute to type 1 diabetes. Although type 1 diabetes usually appears during childhood or adolescence, it can develop in adults. Despite active research, type 1 diabetes has no cure. Treatment focuses on managing blood sugar levels with insulin, diet and lifestyle to prevent complications. Symptoms Type 1 diabetes signs and symptoms can appear relatively suddenly and may include: Increased thirst Frequent urination Bed-wetting in children who previously didn't wet the bed during the night Extreme hunger Unintended weight loss Irritability and other mood changes Fatigue and weakness Blurred vision When to see a doctor Consult your doctor if you notice any of the above signs and symptoms in you or your child. Causes The exact cause of type 1 diabetes is unknown. Usually, the body's own immune system — which normally fights harmful bacteria and viruses — mistakenly destroys the insulin-producing (islet, or islets of Langerhans) cells in the pancreas. Other possible causes include: Genetics Exposure to viruses and other environmental factors The role of insulin Once a significant number of islet cells are destroyed, you'll produce little or no insulin. Insulin is a hormone that comes from a gland situated behind and below the stomach (pancreas). The pancreas secretes insulin into the bloodstream. Insulin circulates, allowing sugar to enter your cells. Insulin lowers the amount of sugar in your bloodstream. As your blood sugar level drops, so does the secre Continue reading >>
Type 1 Diabetes
Alicia Thomas Diaz, M.D. What is type 1 diabetes? Type 1 diabetes, sometimes called insulin-dependent diabetes and juvenile diabetes, can develop at any age but most often occurs in children, teens, and young adults. In type 1 diabetes, a person’s pancreas produces little or no insulin, so insulin treatment is needed for a lifetime. The causes of type 1 diabetes are not fully known. In most cases, the body’s immune system attacks and destroys the part of the pancreas that produces insulin. This occurs over a period of time. so early on in type 1 diabetes, people may not have any symptoms. It is only when enough of the insulin producing cells are affected and insulin producing cells are affected and insulin levels are low that blood sugar rises and symptoms of diabetes start to occur. Because type 1 is an autoimmune disease, people with other autoimmune, conditions, such as Hashimoto disease or primary adrenal insufficiency (also known as Addison's Disease), are more likely to develop type 1 diabetes. Overall, cases of type 1 diabetes seem to be increasing. What are the symptoms of type 1 diabetes? The symptoms of type 1 diabetes can look like other conditions or medical problems. If you (or your child) have these symptoms, talk with your doctor as soon as possible. Increased thirst Increased urination Constant hunger Weight loss Blurred vision Constantly feeling tired How is type 1 diabetes diagnosed and treated? Your doctor will use blood tests to diagnose diabetes. A blood glucose level above 125 mg/dL after fasting overnight or above 200 mg/dL after eating may indicate diabetes. Your doctor may also take a medical history and order further blood tests to rule out type 2 diabetes. People with type 1 diabetes must have daily injections of insulin to keep a normal l Continue reading >>
Diabetes - Type 1
Description An in-depth report on the causes, diagnosis, and treatment of type 1 diabetes. Alternative Names Type 1 diabetes; Insulin-dependent diabetes; Juvenile diabetes Highlights Type 1 Diabetes In type 1 diabetes, the pancreas does not produce insulin. Insulin is a hormone that is involved in regulating how the body converts sugar (glucose) into energy. People with type 1 diabetes need to take daily insulin shots and carefully monitor their blood glucose levels. Type 1 diabetes is much less common than type 2 diabetes. It accounts for 5 - 10% of all diabetes cases. Type 1 diabetes can occur at any age, but it usually first develops in childhood or adolescence. Symptoms of Diabetes Symptoms of both type 1 and type 2 diabetes include: Frequent urination Excessive thirst Extreme hunger Sudden weight loss Extreme fatigue Irritability Blurred vision In general, the symptoms of type 1 diabetes come on more abruptly and are more severe than those of type 2 diabetes. Warning Signs of Hypoglycemia Hypoglycemia (low blood sugar) occurs when blood sugar (glucose) levels fall below normal. All patients with diabetes should be aware of these symptoms of hypoglycemia: Sweating Trembling Hunger Rapid heartbeat Confusion It is important to quickly treat hypoglycemia and raise blood sugar levels by eating sugar, sucking on hard candy, or drinking fruit juice. Patients who are at risk for hypoglycemia should carry some sugar product, or an emergency glucagon injection kit, in case an attack occurs. In rare and worst cases, hypoglycemia can lead to coma and death. Regular blood sugar monitoring throughout the day can help you avoid hypoglycemia. Patients are also encouraged to wear a medical alert ID bracelet or necklace that states they have diabetes and that they take insulin. Pati 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 >>
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 >>
Diabetes (mellitus, Type 1 And Type 2) (cont.)
A A A Type 1 diabetes (T1D): The body stops producing insulin or produces too little insulin to regulate blood glucose level. Type 1 diabetes affects about 10% of all people with diabetes in the United States. Type 1 diabetes is typically diagnosed during childhood or adolescence. It used to be referred to as juvenile-onset diabetes or insulin-dependent diabetes mellitus. Insulin deficiency can occur at any age due to destruction of the pancreas by alcohol, disease, or removal by surgery. Type 1 diabetes also results from progressive failure of the pancreatic beta cells, the only cell type that produces significant amounts of insulin. People with type 1 diabetes require daily insulin treatment to sustain life. Type 2 diabetes (T2D): Although the pancreas still secretes insulin, the body of someone with type 2 diabetes is partially or completely incapable of responding to insulin. This is often referred to as insulin resistance. The pancreas tries to overcome this resistance by secreting more and more insulin. People with insulin resistance develop type 2 diabetes when they fail to secrete enough insulin to cope with their body's demands. At least 90% of adult individuals with diabetes have type 2 diabetes. Type 2 diabetes is typically diagnosed during adulthood, usually after age 45 years. It was once called adult-onset diabetes mellitus, or non-insulin-dependent diabetes mellitus. These names are no longer used because type 2 diabetes does occur in young people, and some people with type 2 diabetes require insulin therapy. Type 2 diabetes is usually controlled with diet, weight loss, exercise, and/or oral medications. However, more than half of all people with type 2 diabetes require insulin to control their blood sugar levels at some point during the course of their i Continue reading >>

Type 1 Diabetes
Type 1 diabetes is the type of diabetes that typically develops in children and in young adults. In type 1 diabetes the body stops making insulin and the blood sugar (glucose) level goes very high. Treatment to control the blood glucose level is with insulin injections and a healthy diet. Other treatments aim to reduce the risk of complications. They include reducing blood pressure if it is high and advice to lead a healthy lifestyle. What is type 1 diabetes? What is type 1 diabetes?

Understanding Adult-onset Type 1 Diabetes
When then 34-year-old Rebecca Gill was pregnant with her second child in 2004, high blood sugar levels led to a diagnosis of gestational diabetes, an often-temporary form of diabetes that can occur in pregnant women. After Gill’s son was born, her blood sugar levels returned to normal, and her doctors assumed that the diabetes was gone. But another blood test given several weeks after she gave birth showed that her diabetes problems had returned. She was referred to an endocrinologist who ran tests and eventually diagnosed her with latent autoimmune diabetes in adults, or LADA. “Thankfully, I was one of the lucky ones whose endocrinologist had experience with LADA,” says Gill, an internet marketing consultant in Commerce, Mich. LADA, also known as type 1.5 diabetes or double diabetes, is a form of diabetes in which an adult’s immune system destroys beta cells in the pancreas, cells that produce insulin. Insulin is a hormone that converts the body’s blood sugar to energy. Without enough insulin, blood sugar levels can become too high, resulting in nerve damage, blindness, and other problems if untreated. LADA is similar to type 1 diabetes in that both forms are caused by the immune system mistakenly attacking beta cells. However, most diabetics with LADA are diagnosed after age 30, while the most common form of type 1 diabetes usually develops in children or adolescents. LADA: A Different Diabetes Because LADA appears in adulthood, it may be initially mistaken for type 2 diabetes, but it is different. People who have LADA are often initially misdiagnosed with type 2 diabetes, says Priscilla Hollander, MD, PhD, an endocrinologist at Baylor University Medical Center in Dallas. “Many people with LADA present symptoms a little like type 2s,” Dr. Hollander expla Continue reading >>
Type 1 Diabetes
The Facts Diabetes is a condition of elevated blood sugars in which the body does not make enough insulin and/or the insulin being made cannot be used properly by the body. The body's main fuel is a form of sugar called glucose, which comes from food (after it's been broken down). Glucose enters the blood and is used by cells for energy. To use glucose, the body needs a hormone called insulin, which is made by the pancreas. Insulin is important because it allows glucose to leave the blood and enter the body's cells. Diabetes develops when your body can't make any or enough insulin, or when it can't properly use the insulin it makes. There are two main types of diabetes: type 1 and type 2. Type 1 diabetes develops when your body makes little or no insulin. When this happens, glucose can't get into the cells for energy and remains in the blood, causing hyperglycemia (high blood sugar). Type 1 diabetes is an autoimmune condition. Most people develop type 1 diabetes before the age of 30, but it can also occur in older adults. In North America, 5% to 10% of people with diabetes have type 1 diabetes. It occurs equally among women and men. Causes There is a genetic predisposition for type 1 diabetes, but the exact science behind the condition is not yet fully understood. There is also the need for certain environmental factors or "triggers" to be involved that lead to the condition. While the exact cause of type 1 diabetes isn't known, researchers believe the disease develops when a virus or environmental toxin damages the pancreas or causes the body's immune system to attack the beta cells of the pancreas (called an autoimmune reaction). As a result, the beta cells of the pancreas can no longer produce enough insulin. Without insulin, glucose in the blood can't enter the cell Continue reading >>
"Diabetes" redirects here. For other uses, see Diabetes (disambiguation). Diabetes mellitus (DM), commonly referred to as diabetes, is a group of metabolic disorders in which there are high blood sugar levels over a prolonged period. Symptoms of high blood sugar include frequent urination, increased thirst, and increased hunger. If left untreated, diabetes can cause many complications. Acute complications can include diabetic ketoacidosis, hyperosmolar hyperglycemic state, or death. Serious long-term complications include cardiovascular disease, stroke, chronic kidney disease, foot ulcers, and damage to the eyes. Diabetes is due to either the pancreas not producing enough insulin or the cells of the body not responding properly to the insulin produced. There are three main types of diabetes mellitus: Type 1 DM results from the pancreas's failure to produce enough insulin. This form was previously referred to as "insulin-dependent diabetes mellitus" (IDDM) or "juvenile diabetes". The cause is unknown. Type 2 DM begins with insulin resistance, a condition in which cells fail to respond to insulin properly. As the disease progresses a lack of insulin may also develop. This form was previously referred to as "non insulin-dependent diabetes mellitus" (NIDDM) or "adult-onset diabetes". The most common cause is excessive body weight and insufficient exercise. Gestational diabetes is the third main form, and occurs when pregnant women without a previous history of diabetes develop high blood sugar levels. Prevention and treatment involve maintaining a healthy diet, regular physical exercise, a normal body weight, and avoiding use of tobacco. Control of blood pressure and maintaining proper foot care are important for people with t Continue reading >>
Type 1 Diabetes
Overview Diabetes is a lifelong condition that causes a person's blood sugar (glucose) level to become too high. The hormone insulin, produced by the pancreas, is responsible for controlling the amount of glucose in the blood. There are two main types of diabetes: type 1 – where the pancreas doesn't produce any insulin type 2 – where the pancreas doesn't produce enough insulin or the body's cells don't react to insulin These pages are about type 1 diabetes. Other types of diabetes are covered separately (read about type 2 diabetes, and gestational diabetes, which affects some women during pregnancy). Symptoms of diabetes Typical symptoms of type 1 diabetes are: feeling very thirsty passing urine more often than usual, particularly at night feeling very tired weight loss and loss of muscle bulk The symptoms of type 1 diabetes usually develop very quickly in young people (over a few days or weeks). In adults, the symptoms often take longer to develop (a few months). Read more about the symptoms of type 1 diabetes. These symptoms occur because the lack of insulin means that glucose stays in the blood and isn’t used as fuel for energy. Your body tries to reduce blood glucose levels by getting rid of the excess glucose in your urine. It's very important for diabetes to be diagnosed as soon as possible, because it will get progressively worse if left untreated. Find your local GP service Read about how type 1 diabetes is diagnosed. Causes of type 1 diabetes Type 1 diabetes is an autoimmune condition, which means your immune system attacks healthy body tissue by mistake. In this case, it attacks the cells in your pancreas. Your damaged pancreas is then unable to produce insulin. So, glucose cannot be moved out of your bloodstream and into your cells. Type 1 diabetes is o Continue reading >>
Type 1 Diabetes: What Are The Symptoms?
What Is Type 1 Diabetes (Juvenile)? Type 1 diabetes is a chronic condition that usually starts in childhood, but can occur in adults (30 to 40-year-olds). In type 1 diabetes, the pancreas produces very little insulin. Insulin helps cells in the body convert sugar into energy. When the pancreas cannot make enough insulin, sugar starts to build up in the blood, causing life-threatening complications. Individuals with type 1 diabetes must take some form of insulin for the rest of their lives. Unusual Thirst Symptoms Unusual thirst is a very common symptom of type 1 diabetes. This condition causes the kidneys to remove excess sugar in the blood by getting rid of more water. The water is removed through urinating, causing dehydration and dehydration causes you to drink more water. Weight Loss Symptoms Patient with type 1 diabetes develop unintentional weight loss and an increase in appetite because blood sugar levels remain high and the body metabolizes fat for energy. Disrupted glucose metabolism also causes patient to feel a lack of energy and drowsy for extended periods Excess urination also cause weight loss because many calories are leaving the body in urine. Skin Problems Symptoms The disruption in glucose metabolism in patient with type 1 diabetes causes skin changes. Type 1 diabetics are at a higher risk for bacterial infections and fungal infections. Poor blood circulation in the skin may also occur. Patient with type 1 diabetes are often infected with fungal infections caused by the yeast Candida albicans. Common fungal infections include athlete's foot, vaginal yeast infection in women, jock itch, ringworm, and diaper rashes in babies. Diaper rash caused by the yeast Candida albicans can spread to other areas of the body such as the stomach and legs. Other Dangero Continue reading >>
How Does Type 1 Diabetes Develop?
WHAT DID BOTTAZZO PORTEND? The Bottazzo article (3) was unique in its form of presentation, in that the prose represented the equivalent workings of a legal stenographer recording the debate between two counsels: one for the prosecution (i.e., β-cell homicide) the other representing the defense (i.e., β-cell suicide). More important than the means for its presentation was the evidence noted for each case. Arguments for homicide included, but were not limited to, a theoretic scenario wherein type 1 diabetes was posed to be initiated by an ill-defined environmental attack resulting in the release of β-cell autoantigens (Fig. 1). Subsequently, those self-antigens were thought to be scavenged by macrophages, presented by major histocompatibility complex (MHC) class II molecules (i.e., HLA-DR), leading to the activation of helper T-cells, which would in turn activate B-cells to produce antibodies (e.g., islet cell cytoplasmic autoantibodies and complement-fixing autoantibodies) as well as activate killer cells and cytotoxic T-cells. Interestingly, Bottazzo did note the potential role for “suppressor T-lymphocytes” (i.e., a forerunner of today’s regulatory T-cell), but left them out of the equation because of their ill-defined nature at the time of his writing. Other prosecutorial arguments included seasonality for the disease onset, typical age of onset, and questions related to genetic susceptibility to this disease. FIG. 1. Bottazzo’s “Exhibit 5.” Diagram shows the hypothetical steps leading to activation of the immune system against the β-cell. A: The triggering events: 1) Environmental attack. 2) Release of autoantigens from the β-cell. 3) The macrophage processes them on its surface membrane.
