Some herbal diabetes products have turned out to be downright dangerous. In February 2000, the FDA recalled five Chinese herbal products after discovering that they contained various amounts of two prescription diabetes drugs, phenformin and glyburide. (The products are listed at Phenformin was withdrawn from the U.S. market 20 years ago after it caused serious side effects, including several deaths.
But does Darkes' story really mean type 1 diabetes can be cured? Darkes declined to provide his medical records, and the experts Live Science spoke to said there were several missing or confusing pieces of information in his story. Usually, incredible medical stories like this one are reported as case reports in the medical literature, the experts said. And even if the details of his story can ultimately be confirmed, the experts emphasized that it's extremely unlikely that Darkes' case would lead to a widespread cure for type 1 diabetes, as reports in the media have wrongly suggested.

Big pharma are in the early stages of developing their own cell therapy approaches for diabetes. Novo Nordisk, one of the largest providers of diabetes treatments, is bidding for stem cells and an encapsulation device, stating that the first clinical trial could take place in the “next few years.” Sanofi, also a big name in diabetes, is working with the German Evotec in a beta cell replacement therapy for diabetics.
Type 2 diabetes, although influenced by a person’s genes, is largely thought to be brought about by a poor diet and being overweight for prolonged periods of time, particularly at an old age. The pancreas is either unable to produce enough insulin, or the body’s cells simply don’t react to insulin, which leads to dangerously high blood sugar levels.
Cinnamon has the ability to lower blood sugar levels and improve your sensitivity to insulin. A study conducted at Western University of Health Sciences in Pomona, Calif. found that the consumption of cinnamon is associated with a statistically significant decrease in plasma glucose levels, LDL cholesterol and triglyceride levels. Cinnamon consumption also helped increase HDL cholesterol levels. (15)
What are the symptoms of prediabetes? People typically do not have symptoms of prediabetes, which is partially why up to 90% of people don’t know they have it. The ADA reports that some people with prediabetes may develop symptoms of type 2 diabetes, though even many people diagnosed with type 2 diabetes show little or no symptoms initially at diagnosis.
Metformin (Glucophage) is a biguanide. Biguanides lower blood glucose levels primarily by decreasing the amount of glucose produced by the liver. Metformin also helps to lower blood glucose levels by making muscle tissue more sensitive to insulin so glucose can be absorbed. It is usually taken two times a day. A side effect of metformin may be diarrhea, but this is improved when the drug is taken with food.
A wide scatter of absolute levels of pancreas triacylglycerol has been reported, with a tendency for higher levels in people with diabetes (57). This large population study showed overlap between diabetic and weight-matched control groups. These findings were also observed in a more recent smaller study that used a more precise method (21). Why would one person have normal β-cell function with a pancreas fat level of, for example, 8%, whereas another has type 2 diabetes with a pancreas fat level of 5%? There must be varying degrees of liposusceptibility of the metabolic organs, and this has been demonstrated in relation to ethnic differences (72). If the fat is simply not available to the body, then the susceptibility of the pancreas will not be tested, whereas if the individual acquires excess fat stores, then β-cell failure may or may not develop depending on degree of liposusceptibility. In any group of people with type 2 diabetes, simple inspection reveals that diabetes develops in some with a body mass index (BMI) in the normal or overweight range, whereas others have a very high BMI. The pathophysiologic changes in insulin secretion and insulin sensitivity are not different in obese and normal weight people (73), and the upswing in population rates of type 2 diabetes relates to a right shift in the whole BMI distribution. Hence, the person with a BMI of 24 and type 2 diabetes would in a previous era have had a BMI of 21 and no diabetes. It is clear that individual susceptibility factors determine the onset of the condition, and both genetic and epigenetic factors may contribute. Given that diabetes cannot occur without loss of acute insulin response to food, it can be postulated that this failure of acute insulin secretion could relate to both accumulation of fat and susceptibility to the adverse effect of excess fat in the pancreas.
The researchers concluded that the herb might help treat or prevent type 2 diabetes. They noted that S. oblonga appears to act in the same way as today’s oral diabetes drugs (alpha-glucoside inhibitors) in interfering with the absorption of carbohydrates. S. oblonga is not free of side effects, however. It can cause the same gas and cramping as the prescription drugs, particularly in higher doses.
It’s long been believed that the condition is manageable, but not curable. According to findings published in the journal The Lancet, however, type 2 diabetes can be reversed through weight loss. More specifically, by reducing the amount of fat being carried in and around the abdomen, as accumulated fat in this region impedes the function of the pancreas.

In diabetes, either the pancreas makes insufficient levels of insulin so cells absorb glucose poorly or cells themselves become insulin resistant and thus unable to absorb glucose despite adequate insulin levels. Both types of change increase blood sugar levels above normal. Parsed this way, type I and type II diabetes overlap some but also differ.
The results of his medical tests are still being analyzed, Darkes said, but he hasn't needed insulin injections for a year and a half. "It took a long time to sink in," he noted. But Darkes is confident he no longer has type 1 diabetes. He said that doctors told him that he has a "rare" gene that somehow facilitated his cure. "I'm the only one who carries [the gene], at the moment," and there's no further explanation so far, he said.

For over a decade, Cummings and others have tried to reframe the very concept of bariatric surgery (they prefer “metabolic surgery”). Their work has shown these procedures just don’t change how much food the stomach can fit; they trigger a cascade of metabolic and bodily changes, many of which help people with type 2 diabetes naturally get their blood sugar under control. Some changes even start happening before a patient loses weight, such as higher levels of peptide production in the gut that seem to restore a patient’s sensitivity to insulin.
Trick (important): Cut down on sweets, and if you can, cut them out entirely for a couple months. I still eat ice cream about once a week, and know people who are losing weight on this diet while eating ice cream almost every day. But this probably won’t be the case for everyone. Better to severely restrict sweets for the first few months, and then gradually reintroduce.
