Stem cell research has also been suggested as a potential avenue for a cure since it may permit regrowth of Islet cells which are genetically part of the treated individual, thus perhaps eliminating the need for immuno-suppressants. This new method autologous nonmyeloablative hematopoietic stem cell transplantation was developed by a research team composed by Brazilian and American scientists (Dr. Julio Voltarelli, Dr. Carlos Eduardo Couri, Dr Richard Burt, and colleagues) and it was the first study to use stem cell therapy in human diabetes mellitus This was initially tested in mice and in 2007 there was the first publication of stem cell therapy to treat this form of diabetes. Until 2009, there was 23 patients included and followed for a mean period of 29.8 months (ranging from 7 to 58 months). In the trial, severe immunosuppression with high doses of cyclophosphamide and anti-thymocyte globulin is used with the aim of "turning off" the immunologic system", and then autologous hematopoietic stem cells are reinfused to regenerate a new one. In summary it is a kind of "immunologic reset" that blocks the autoimmune attack against residual pancreatic insulin-producing cells. Until December 2009, 12 patients remained continuously insulin-free for periods ranging from 14 to 52 months and 8 patients became transiently insulin-free for periods ranging from 6 to 47 months. Of these last 8 patients, 2 became insulin-free again after the use of sitagliptin, a DPP-4 inhibitor approved only to treat type 2 diabetic patients and this is also the first study to document the use and complete insulin-independendce in humans with type 1 diabetes with this medication. In parallel with insulin suspension, indirect measures of endogenous insulin secretion revealed that it significantly increased in the whole group of patients, regardless the need of daily exogenous insulin use.
Both type 1 and type 2 diabetes mellitus are chronic conditions that can only be managed using insulin, anti-diabetes medications, lifestyle changes, etc., but cannot be cured. Gestational diabetes generally resolves on itself after the delivery. If not managed properly, diabetes can cause several other complications, like hypoglycemia, diabetic ketoacidosis, nonketotic hyperosmolar coma, etc. Other serious and long-term complications include cardiovascular diseases, chronic renal failure, diabetic retinopathy, etc.
I’ve done this for years and I do it each time I’m pregnant in place of the glucose test. It is a cheap and easy way to keep insulin levels in check and see how your body responds to certain foods. While I can offer general advice on the amount of carbohydrates that should be consumed, at home glucose monitoring allows you to know exactly what your body will and won’t handle.
Even if you don’t have any underlying glucose issues, testing your blood sugar occasionally will help you pin point which carbohydrates you tolerate well and which you don’t. It can help you have a better understanding of your body’s reaction to foods and take control of your health. It is also an accurate alternative to the pregnancy test for gestational diabetes, so talk to your doctor if you’d prefer to test yourself, though you may have to explain your reasons!
Peripheral neuropathy is a problem with the functioning of the nerves outside of the spinal cord. Symptoms may include numbness, weakness, burning pain (especially at night), and loss of reflexes. Possible causes may include carpel tunnel syndrome, shingles, vitamin or nutritional deficiencies, and illnesses like diabetes, syphilis, AIDS, and kidney failure. Peripheral neuropathy is diagnosed with exams and tests. Treatment for the condition depends on the cause. Usually, the prognosis for peripheral neuropathy is good if the cause can be successfully treated or prevented.
If the rapid changes in metabolism following bariatric surgery are a consequence of the sudden change in calorie balance, the defects in both insulin secretion and hepatic insulin sensitivity of type 2 diabetes should be correctable by change in diet alone. To test this hypothesis, a group of people with type 2 diabetes were studied before and during a 600 kcal/day diet (21). Within 7 days, liver fat decreased by 30%, becoming similar to that of the control group, and hepatic insulin sensitivity normalized (Fig. 2). The close association between liver fat content and hepatic glucose production had previously been established (20,22,23). Plasma glucose normalized by day 7 of the diet.

The first hint that type 2 diabetes is a fully reversible syndrome came from bariatric surgery. Almost a quarter century ago, Pories et al. (12) demonstrated that blood glucose levels normalized in obese people with type 2 diabetes undergoing bariatric surgery and that 10 years later, almost 90% remained free of diabetes. The phenomenon was more recently tested in a randomized prospective study comparing gastric banding with intensive medical therapy for type 2 diabetes (13). This least invasive type of surgery was most suitable for the randomized study, although it was associated with lower rates of diabetes reversal than other procedures. Mean fasting plasma glucose fell to normal levels in the surgically treated group but declined only modestly in the intensive medical treatment group despite oral agents and insulin (Fig. 1) (13). Remission of diabetes was related to the degree of weight loss rather than to group allocation and was achieved in 73% of the surgical group and 13% of the intensive medical treatment group because surgery was more effective in achieving weight loss as previously described (14). Type 2 diabetes can be reversed by applying a surgical procedure that diminishes fat mass.
Chromium plays a vital role in binding to and activating the insulin receptor on body cells, reducing insulin resistance. Supplemental chromium has been shown to lower blood sugar levels, lipids, A1C, and insulin in diabetic patients. It can also help decrease one’s appetite, particularly for sweets. A dosage from 200 mcg to 2,000 mcg a day is safe. Higher doses are unnecessary and can cause acute kidney failure.
Together with evidence of normalization of insulin secretion after bariatric surgery (84), insights into the behavior of the liver and pancreas during hypocaloric dieting lead to a hypothesis of the etiology and pathogenesis of type 2 diabetes (Fig. 6): The accumulation of fat in liver and secondarily in the pancreas will lead to self-reinforcing cycles that interact to bring about type 2 diabetes. Fatty liver leads to impaired fasting glucose metabolism and increases export of VLDL triacylglycerol (85), which increases fat delivery to all tissues, including the islets. The liver and pancreas cycles drive onward after diagnosis with steadily decreasing β-cell function. However, of note, observations of the reversal of type 2 diabetes confirm that if the primary influence of positive calorie balance is removed, then the processes are reversible (21).
Gene therapy can be used to turn duodenum cells and duodenum adult stem cells into beta cells which produce insulin and amylin naturally. By delivering beta cell DNA to the intestine cells in the duodenum, a few intestine cells will turn into beta cells, and subsequently adult stem cells will develop into beta cells. This makes the supply of beta cells in the duodenum self replenishing, and the beta cells will produce insulin in proportional response to carbohydrates consumed.
Drugs of this class decrease the absorption of carbohydrates from the intestine. Before being absorbed into the bloodstream, enzymes in the small intestine must break down carbohydrates into smaller sugar particles, such as glucose. One of the enzymes involved in breaking down carbohydrates is called alpha-glucosidase. By inhibiting this enzyme, carbohydrates are not broken down as efficiently, and glucose absorption is delayed.
