Insulin is released into the blood by beta cells (β-cells), found in the islets of Langerhans in the pancreas, in response to rising levels of blood glucose, typically after eating. Insulin is used by about two-thirds of the body's cells to absorb glucose from the blood for use as fuel, for conversion to other needed molecules, or for storage. Lower glucose levels result in decreased insulin release from the beta cells and in the breakdown of glycogen to glucose. This process is mainly controlled by the hormone glucagon, which acts in the opposite manner to insulin.[61]
Insulin is a hormone that is produced by specialized cells (beta cells) of the pancreas. (The pancreas is a deep-seated organ in the abdomen located behind the stomach.) In addition to helping glucose enter the cells, insulin is also important in tightly regulating the level of glucose in the blood. After a meal, the blood glucose level rises. In response to the increased glucose level, the pancreas normally releases more insulin into the bloodstream to help glucose enter the cells and lower blood glucose levels after a meal. When the blood glucose levels are lowered, the insulin release from the pancreas is turned down. It is important to note that even in the fasting state there is a low steady release of insulin than fluctuates a bit and helps to maintain a steady blood sugar level during fasting. In normal individuals, such a regulatory system helps to keep blood glucose levels in a tightly controlled range. As outlined above, in patients with diabetes, the insulin is either absent, relatively insufficient for the body's needs, or not used properly by the body. All of these factors cause elevated levels of blood glucose (hyperglycemia).
Type 2 diabetes is the most common form of diabetes, and unlike type 1 diabetes, it usually occurs in people over the age of 40, especially those who are overweight. Type 2 diabetes is caused by insulin resistance, which means that the hormone insulin is being released, but a person doesn’t respond to it appropriately. Type 2 diabetes is a metabolic disorder that’s caused by high blood sugar. The body can keep up for a period of time by producing more insulin, but over time the insulin receptor sites burn out. Eventually, diabetes can affect nearly every system in the body, impacting your energy, digestion, weight, sleep, vision and more. (5)
The blood vessels and blood are the highways that transport sugar from where it is either taken in (the stomach) or manufactured (in the liver) to the cells where it is used (muscles) or where it is stored (fat). Sugar cannot go into the cells by itself. The pancreas releases insulin into the blood, which serves as the helper, or the "key," that lets sugar into the cells for use as energy.
To treat diabetic retinopathy, a laser is used to destroy and prevent the recurrence of the development of these small aneurysms and brittle blood vessels. Approximately 50% of patients with diabetes will develop some degree of diabetic retinopathy after 10 years of diabetes, and 80% retinopathy after 15 years of the disease. Poor control of blood sugar and blood pressure further aggravates eye disease in diabetes.
Medications used to treat diabetes do so by lowering blood sugar levels. There is broad consensus that when people with diabetes maintain tight glucose control (also called "tight glycemic control") -- keeping the glucose levels in their blood within normal ranges - that they experience fewer complications like kidney problems and eye problems.[84][85] There is however debate as to whether this is cost effective for people later in life.[86]

Each month, ASDA issues a Wellness Challenge that asks you to change your behavior in a way that will positively affect your wellness. Each challenge varies in length and activity, but the goal is the same: to get you paying more attention to your well-being and developing good wellness habits. Each challenge will target one (or more) of ASDA’s five dimensions of wellness: emotional, physical, intellectual, occupational and environmental. December's challenge: Brainy expedition. Learn what it takes now.
India is said to be the diabetes capital of the world. With nearly 50 million people in India suffering from diabetes, the country has a big challenge to face. First, let’s know what is diabetes. The elevated sugar in the blood is called diabetes. There are two primary reasons behind diabetes - one is when our body stops producing insulin and second is when the body does not respond to insulin that is produced by the body. Insulin is broken down by the body and used as energy, which is transported to the cells. There are two types of diabetes - Type I diabetes and Type II diabetes. Let’s know about them in a little detail:
Type 1 diabetes is commonly called “juvenile diabetes” because it tends to develop at a younger age, typically before a person turns 20 years old. Type 1 diabetes is an autoimmune disease where the immune system attacks the insulin-producing beta cells in the pancreas. The damage to the pancreatic cells leads to a reduced ability or complete inability to create insulin. Some of the common causes that trigger this autoimmune response may include a virus, genetically modified organisms, heavy metals, vaccines, or foods like wheat, cow’s milk and soy. (4)
Type 2 diabetes is a completely preventable and reversible condition, and with diet and lifestyle changes, you can greatly reduce your chances of getting the disease or reverse the condition if you’ve already been diagnosed. If you are one of the millions of Americans struggling with diabetes symptoms, begin the steps to reverse diabetes naturally today. With my diabetic diet plan, suggested supplements and increased physical activity, you can quickly regain your health and reverse diabetes the natural way.
Per the WHO, people with fasting glucose levels from 6.1 to 6.9 mmol/l (110 to 125 mg/dl) are considered to have impaired fasting glucose.[67] people with plasma glucose at or above 7.8 mmol/l (140 mg/dl), but not over 11.1 mmol/l (200 mg/dl), two hours after a 75 gram oral glucose load are considered to have impaired glucose tolerance. Of these two prediabetic states, the latter in particular is a major risk factor for progression to full-blown diabetes mellitus, as well as cardiovascular disease.[68] The American Diabetes Association (ADA) since 2003 uses a slightly different range for impaired fasting glucose of 5.6 to 6.9 mmol/l (100 to 125 mg/dl).[69]
In the picture to the right you can see the lunch that I was unbelievably served at the 11th International Congress on Obesity in Stockholm 2010. This is a major international conference for obesity doctors and scientists. The food contains almost exclusively energy from sugar and starches, things that are broken down to simple sugars in the stomach.
