When cells are resistant to insulin, they don’t use the insulin effectively to bring the glucose from the bloodstream into the cell. The pancreas needs to produce more insulin to overcome this resistance in an effort to normalize blood sugar levels. When the pancreas can’t keep up with the insulin demands in a person with insulin resistance, that person develops diabetes.
Rosiglitazone (Avandia) and pioglitazone (ACTOS) are in a group of drugs called thiazolidinediones. These drugs help insulin work better in the muscle and fat and also reduce glucose production in the liver. The first drug in this group, troglitazone (Rezulin), was removed from the market because it caused serious liver problems in a small number of people. So far rosiglitazone and pioglitazone have not shown the same problems, but users are still monitored closely for liver problems as a precaution. Both drugs appear to increase the risk for heart failure in some individuals, and there is debate about whether rosiglitazone may contribute to an increased risk for heart attacks. Both drugs are effective at reducing A1C and generally have few side effects.
This book was written in 1999 so I had this uncanny feeling in the back of my head that a lot of water has run over the dam since it was written. The author is a medical doctor with type 2 diabetes who weighed 313 pounds and was a first year medical student before he got the message of needing to do something about his health. He has some suggestions about reversal of diabetes that are interesting and give me pause for thought. His message in its majority is addressed to diabetics who are not ta ...more
Type 1 diabetes is a particularly unpleasant condition. It occurs when the pancreas ceases to produce the insulin needed by the body to metabolize sugar and, until the invention of artificial insulin injections, it was as deadly as cancer. Type 2 is the less severe form of the disease, where the body produces insufficient insulin; it can often be managed through diet alone.
The reason the body stops producing insulin is that it kills off the pancreas’ beta cells, which produce insulin. People with Type 1 diabetes must get their insulin from injections or ingestion, a cumbersome and often imprecise task. Too little insulin and blood sugar levels stay high for extended periods, potentially damaging the body; too much and blood sugar levels crash, possibly causing a person with diabetes to faint or experience an even worse problems, such as a stroke.
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)
Neem tree leaves have ingredients and compounds that lower blood glucose considerably. This property of neem makes it an excellent home remedy for diabetes. A glassful of neem leaves' juice when consumed first thing in the morning can benefit considerably. Regular and prolonged consumption can even trigger production of insulin and subside diabetes completely.
Pancreatic islet transplantation is an experimental treatment for poorly controlled type 1 diabetes. Pancreatic islets are clusters of cells in the pancreas that make the hormone insulin. In type 1 diabetes, the body’s immune system attacks these cells. A pancreatic islet transplant replaces destroyed islets with new ones that make and release insulin. This procedure takes islets from the pancreas of an organ donor and transfers them to a person with type 1 diabetes. Because researchers are still studying pancreatic islet transplantation, the procedure is only available to people enrolled in research studies. Learn more about islet transplantation studies.
Steve Vincent, 58, from Southampton, England, was diagnosed with type 2 in December 2010. He was told there was no known cure and he had an increased risk of heart attack, stroke, blindness and limb loss. He had a BMI of 29, weighed 93kg and showed an HbA1c of 10.7%. In summer 2011 he read the reversal story and went on a daily 600 calories green vegetable diet and three litres of water, for two months. At the end he was and remains diabetes-free. In December 2012 he told me: "All my blood test levels are within the normal range, and my cholesterol and blood pressure levels are now normal." When he came off the diet he weighed just 72kg, although he has put on weight since then as he admits he has not been eating as healthily as he might, but his BMI remains at a healthy 24, and his HbA1c level is 5.5%.
Diabetes is a costly disease, placing a high financial burden on the patient and the healthcare system. If poorly managed or left untreated, it can cause blindness, loss of kidney function, and conditions that require the amputation of digits or limbs. The CDC reports that it’s also a major cause of heart disease and stroke and the seventh leading cause of death in the United States.
The most commonly prescribed oral medication for type 2 diabetes is metformin. “Usually it’s the first line of treatment for all people with type 2 diabetes if their kidney function is normal,” Dr. Gupta says. In fact, a survey published in November 2015 in the journal JAMA found that metformin was one of the most commonly used drugs in the United States.
However, the observation that normalization of glucose in type 2 diabetes occurred within days after bariatric surgery, before substantial weight loss (15), led to the widespread belief that surgery itself brought about specific changes mediated through incretin hormone secretion (16,17). This reasoning overlooked the major change that follows bariatric surgery: an acute, profound decrease in calorie intake. Typically, those undergoing bariatric surgery have a mean body weight of ∼150 kg (15) and would therefore require a daily calorie intake of ∼13.4 MJ/day (3,200 kcal/day) for weight maintenance (18). This intake decreases precipitously at the time of surgery. The sudden reversal of traffic into fat stores brings about a profound change in intracellular concentration of fat metabolites. It is known that under hypocaloric conditions, fat is mobilized first from the liver and other ectopic sites rather than from visceral or subcutaneous fat stores (19). This process has been studied in detail during more moderate calorie restriction in type 2 diabetes over 8 weeks (20). Fasting plasma glucose was shown to be improved because of an 81% decrease in liver fat content and normalization of hepatic insulin sensitivity with no change in the insulin resistance of muscle.
Want to learn more about diabetes drugs? Read the “Diabetes Medicines” series from certified diabetes educator Amy Campbell, covering metformin, sulfonylureas, meglitinides, thiazolidinediones, DPP-4 inhibitors, SGLT2 inhibitors, alpha-glucosidase inhibitors, bile acid sequestrants and dopamine receptor agonists, and non-insulin injectable diabetes medications.
The extent of weight loss required to reverse type 2 diabetes is much greater than conventionally advised. A clear distinction must be made between weight loss that improves glucose control but leaves blood glucose levels abnormal and weight loss of sufficient degree to normalize pancreatic function. The Belfast diet study provides an example of moderate weight loss leading to reasonably controlled, yet persistent diabetes. This study showed that a mean weight loss of 11 kg decreased fasting blood glucose levels from 10.4 to 7.0 mmol/L but that this abnormal level presaged the all-too-familiar deterioration of control (87).
But a prescription doesn’t have to be a life sentence. It may be that, through weight loss and physical activity, you can reduce your risk of diabetes, or prevent it from occurring. "The only evidence-based treatment that can 'cure' diabetes is weight-loss surgery,” says Gupta, “but weight loss in overweight or obese type 2 diabetes patients certainly helps with decreasing drugs.”
One easy way to increase your fat content and quit snacking is to begin your meal by eating an avocado. I and others I know have used this trick to easily quit snacking. Avocados protect you from one of the reasons some dietary research wrongly claims that high-fat diets are bad for you: the danger of gorging yourself on delicious, fatty foods. With plain avocados, there is little danger of gorging. Another danger is clogging your arteries and giving yourself heart disease. But it’s been amply shown that the blame for that falls squarely on trans fats, like margarine. If you see any product with the words “partially hydrogenated” or “hydrogenated” in the list of ingredients, put it back, it’s a trans fat. On the other hand, any fat that comes directly from an animal or plant is not a trans fat and can be safely consumed.
