The twin cycle hypothesis of the etiology of type 2 diabetes. During long-term intake of more calories than are expended each day, any excess carbohydrate must undergo de novo lipogenesis, which particularly promotes fat accumulation in the liver. Because insulin stimulates de novo lipogenesis, individuals with a degree of insulin resistance (determined by family or lifestyle factors) will accumulate liver fat more readily than others because of higher plasma insulin levels. In turn, the increased liver fat will cause relative resistance to insulin suppression of hepatic glucose production. Over many years, a modest increase in fasting plasma glucose level will stimulate increased basal insulin secretion rates to maintain euglycemia. The consequent hyperinsulinemia will further increase the conversion of excess calories to liver fat. A cycle of hyperinsulinemia and blunted suppression of hepatic glucose production becomes established. Fatty liver leads to increased export of VLDL triacylglycerol (85), which will increase fat delivery to all tissues, including the islets. This process is further stimulated by elevated plasma glucose levels (85). Excess fatty acid availability in the pancreatic islet would be expected to impair the acute insulin secretion in response to ingested food, and at a certain level of fatty acid exposure, postprandial hyperglycemia will supervene. The hyperglycemia will further increase insulin secretion rates, with consequent enhancement of hepatic lipogenesis, spinning the liver cycle faster and driving the pancreas cycle. Eventually, the fatty acid and glucose inhibitory effects on the islets reach a trigger level that leads to a relatively sudden onset of clinical diabetes.

Gymnema Sylvestre is a vine native to Central & South India. Used in traditional Indian medicine since the 6th century BC, the leaves of this plant contain ‘gymnemic acids’ that have the amazing ability to slow down the transport of glucose from the intestines to the bloodstream. Some scientists even believe that Gymnema Sylvestre extract can help repair and regenerate pancreatic beta cells that produce insulin!
Other research conducted at the same institute studied possible regeneration of the islets of langerhans in rats that were made diabetic for the study and then given gymnema sylvestre leaf extracts. The diabetic rats were able to double the number of their islets and beta cell numbers. Researchers felt that the herbal therapy was able to bring blood sugar stability by repairing the pancreas and increasing insulin secretion.
Tooth decay and cavities are some of the first oral problems that individuals with diabetes are at risk for. Increased blood sugar levels translate into greater sugars and acids that attack the teeth and lead to gum diseases. Gingivitis can also occur as a result of increased blood sugar levels along with an inappropriate oral hygiene. Periodontitis is an oral disease caused by untreated gingivitis and which destroys the soft tissue and bone that support the teeth. This disease may cause the gums to pull away from the teeth which may eventually loosen and fall out. Diabetic people tend to experience more severe periodontitis because diabetes lowers the ability to resist infection and also slows healing. At the same time, an oral infection such as periodontitis can make diabetes more difficult to control because it causes the blood sugar levels to rise.
Treatment for diabetes requires keeping close watch over your blood sugar levels (and keeping them at a goal set by your doctor) with a combination of medications, exercise, and diet. By paying close attention to what and when you eat, you can minimize or avoid the "seesaw effect" of rapidly changing blood sugar levels, which can require quick changes in medication dosages, especially insulin.
Type 2 diabetes is almost always reversible and this is almost ridiculously easy to prove. This is great news for the more than 50% of American adults who have been diagnosed with pre-diabetes or diabetes. Recognizing this truth is the crucial first step in reversing your diabetes or pre-diabetes. Actually, it something that most people already instinctively recognized to be true.
The problem is, glucose is actually toxic if it is just floating around in your bloodstream, so that body has a defense mechanism. Any glucose that is not immediately used is stored as glycogen in the liver and the muscles. This would be all well and good except that your body has a limited number of glycogen receptors. When these are full, as they almost always are in inactive people, the body only has one option left: to store all the excess glucose as saturated fat within the body.
Cinnamon has long been reported as a good source for the treatment of diabetes, due to a study done in 2003 by Khan and associates. 60 people were tested in the group and one third of the group was given a placebo. The end results were very impressive and the overall health of the group was increased with glucose down 18 percent; LDL cholesterol and triglycerides also showed reduced levels. Everyone was excited and the word of using cinnamon spread.
Storage of liver fat can only occur when daily calorie intake exceeds expenditure. Sucrose overfeeding for 3 weeks has been shown to cause a 30% increase in liver fat content (37). The associated metabolic stress on hepatocytes was reflected by a simultaneous 30% rise in serum alanine aminotransferase (ALT) levels, and both liver fat and serum ALT returned to normal levels during a subsequent hypocaloric diet. Superimposed upon a positive calorie balance, the extent of portal vein hyperinsulinemia determines how rapidly conversion of excess sugars to fatty acid occurs in the liver. In groups of both obese and nonobese subjects, it was found that those with higher plasma insulin levels have markedly increased rates of hepatic de novo lipogenesis (2,38,39). Conversely, in type 1 diabetes the relatively low insulin concentration in the portal vein (as a consequence of insulin injection into subcutaneous tissue) is associated with subnormal liver fat content (40). Initiation of subcutaneous insulin therapy in type 2 diabetes brings about a decrease in portal insulin delivery by suppression of pancreatic insulin secretion and, hence, a decrease in liver fat (41). Hypocaloric diet (42), physical activity (43), or thiazolidinedione use (23,44) each reduces insulin secretion and decreases liver fat content. Newly synthesized triacylglycerol in the liver will be either oxidized, exported, or stored as hepatic triacylglycerol. Because transport of fatty acid into mitochondria for oxidation is inhibited by the malonyl-CoA produced during de novo lipogenesis, newly synthesized triacylglycerol is preferentially directed toward storage or export. Hence, hepatic fat content and plasma VLDL triacylglycerol levels are increased.
According to studies, cinnamon may have a positive effect on the glycemic control and the lipid profile in patients with diabetes mellitus type 2. This is because it contains 18% polyphenol content in dry weight. This popular Indian spice can improve insulin sensitivity and blood glucose control. According to a study published in Journal Of The American Board Of Family Medicine, “cinnamon lowered HbA1C by 0.83% compared with standard medication alone lowering HbA1C 0.37%. Taking cinnamon could be useful for lowering serum HbA1C in type 2 diabetics with HbA1C >7.0 in addition to usual care.”
Recent research shows that the first step in Diabetes management should be for patients to be put on a low carb diet. Patients that are put on a high carb diet find it very difficult to maintain normal blood glucose levels. Patients that are put on a low carb or restricted carbohydrate diet, manage to maintain near normal blood glucose levels and A1cs.
When the weight loss lessens the liver and pancreas fat, the insulin-producing beta cells in the pancreas come to life again. "Almost everyone will return to normal if they lose a substantial amount of weight," Taylor says. "This is a simple disease." What's yet to be figured out, he says, is why the weight loss doesn't lead to a reversal in everyone.
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.
Insulin is a hormone that helps glucose get where it needs to go. When your body senses that you’ve eaten something, your pancreas produces insulin to help your cells absorb sugar. If you didn’t have insulin, your cells wouldn’t receive their glucose fuel, and your body would sense sugar in your bloodstream and eventually store it as fat because your cells didn’t use it.
Note that these medications used to treat type 2 diabetes are typically not used in pregnant or breastfeeding women. At present the only recommended way of controlling diabetes in women who are pregnant or breastfeeding is by diet, exercise, and insulin therapy. You should speak with your health-care professional if you are taking these medications, are considering becoming pregnant, or if you have become pregnant while taking these medications.
