Meanwhile, American Diabetes Scientist Zhen Gu, PhD, a professor in the Joint University of North Carolina/North Carolina State University Department of Biomedical Engineering, is working to develop a “smart insulin” patch that imitates the body's beta cells by both sensing blood glucose levels and releasing insulin using a nanotechnology that leverages bioengineering, biochemistry and materials science.
If you have gestational diabetes, you should first try to control your blood glucose level by making healthy food choices and getting regular physical activity. If you can’t reach your blood glucose target, your health care team will talk with you about diabetes medicines, such as insulin or the diabetes pill metformin, that may be safe for you to take during pregnancy. Your health care team may start you on diabetes medicines right away if your blood glucose is very high.
In type 1 diabetes, patients sometimes experience what physicians have come to call a "honeymoon period" shortly after the disease is diagnosed. During the "honeymoon period" diabetes may appear to go away for a period of a few months to a year. The patient's insulin needs are minimal and some patients may actually find they can maintain normal or near normal blood glucose taking little or no insulin.
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)

Answer:  In recent years, intermittent fasting has emerged as a novel way of treating patients with type 2 diabetes. There are anecdotal reports of patients who have lost weight, their blood sugar levels have improved significantly, and they no longer need to take their diabetes medications. Their disease appears to be in remission – if not exactly cured.
Complete with success stories featuring people who followed the plan and not only lost weight (up to 50 pounds) but were also no longer diagnosed as diabetic, the Diabetes Cure teaches readers what's really causing their diabetes, shows them how to banish cravings once and for all, and provides the tools to help them take back control of their lives.
According to the American Diabetes Association, islet transplantation can replace insulin injections and provide more physiological glucose control, but “there are not sufficient donor islets available for all the individuals who need them, and often it takes islets from several donors to transplant one recipient, exacerbating the donor shortage. A major reason for the need for multiple donors is that more than 80% of transplanted islets die within the first week after transplantation. The surviving islets may overwork and gradually die from exhaustion.”

We really can't blame anyone who says there's no cure for type-2 Diabetes. But there are 1000s of them who are completely cured of Diabetes and living normal life like us. The only problem here is, they are only in thousands who are completely cured of Diabetes while there are millions of them who are struggling with Diabetes forever. That's the reason, we feel Diabetes has no cure.
Herbal prescriptions for diabetes are formulated or prescribed based on the patient’s predominant symptoms. For instance, a patient presenting primarily with excessive thirst (lung Yin deficiency) might be given a single herb, such as radix panacis quinquefolii; or a combination of herbs in a patent formulation such as yu chuan wan, which is used in general to treat diabetes of mild to moderate severity and specifically to treat excessive thirst due to Yin deficiency,12 and ba wei di huang tang (“eight-ingredient pill with rehmannia”), which was originally used to treat people exhibiting weakness, fatigue, and copious urine soon after drinking water.13
“I am extremely pleased to see that technology developed in Tejal Desai’s group is getting to the point that we can explore this for therapeutic purposes,” Matthias Hebrok, PhD, the director of the Diabetes Center at UCSF and a member of Encellin’s scientific advisory board, noted on the UCSF website. “Encapsulation and protection of islet cells remain a critical hurdle that needs to be overcome before cell therapy becomes a reality in type 1 diabetes.”
These findings present a hopeful option not just for improved management of the condition, but a potential cure. One that doesn’t rely on expensive medications or invasive surgery, but instead, on improved diet and lifestyle — which could also be beneficial in managing and preventing a number of other chronic conditions which are affected by weight. As Taylor told The Guardian, “The weight loss goals provided by this programme [sic] are achievable for many people. The big challenge is long-term avoidance of weight re-gain.”
As of 2010, an estimated of 285 million people have type 2 diabetes globally, making up about 90% of all the diabetes cases. There is an alarming rise in the prevalence of diabetes in every part of the world, thanks to the eating habits and sedentary lifestyle. And, as opposed to the misconception that eating sweets can result in diabetes, stress and genes can also play a major role in this. As of today, number of diabetics is far more than anytime in the past. Now, even younger generation is not spared by this disease. Generally, diabetes is more common in people who are overweight or obese. Generally, fasting blood sugar levels per 100 ml of blood should be between 80 to 120 mg, which can go up to 160 mg/100 ml of blood after meals. Anything that is constantly above 160 mg/100 ml indicates diabetes. Usually, older and obese people are at increased risk of diabetes because of their inability to produce insulin and lifestyle.
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.
Alcohol: Alcohol can dangerously increase blood sugar and lead to liver toxicity. Research published in Annals of Internal Medicine found that there was a 43 percent increased incidence of diabetes associated with heavy consumption of alcohol, which is defined as three or more drinks per day. (8) Beer and sweet liquors are especially high in carbohydrates and should be avoided.
It’s fairly standard practice for physicians to encourage, if not prescribe, a healthy diet for most of their patients, especially those with type 2 diabetes. But dietary guidance has not traditionally been the focus of treatment for diabetes and similar conditions. “Rather than addressing the root cause, management guidelines for type 2 diabetes focus on reducing blood sugar levels through drug treatments. Diet and lifestyle are touched upon, but diabetes remission by cutting calories is rarely discussed,” Taylor told The Guardian.
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. 
Because the drugs listed above act in different ways to lower blood glucose levels, they may be used together. For example, a biguanide and a sulfonylurea may be used together. Many combinations can be used. Though taking more than one drug can be more costly and can increase the risk of side effects, combining oral medications can improve blood glucose control when taking only a single pill does not have the desired effects. Switching from one single pill to another is not as effective as adding another type of diabetes medicine.
According to the American Diabetes Association, nearly 21 million people in the United States have diabetes, with about 90 percent to 95 percent having type 2 diabetes. Sugar, in the form of glucose, is the main source of fuel for body cells. The hormone insulin allows glucose in the blood to enter cells. In type 2 diabetes, either the body doesn't produce enough insulin or cells are resistant to effects of insulin.
Oregano and Sage: One group of researchers tested a variety of herbs and spices for a specific antioxidant activity that help to prevent an increase in hemoglobin A1C, a protein maker in the blood that is affected by blood sugar levels. They found that two of the herbs with the highest antioxidant levels were oregano and sage (1)…can you say Italian food?
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.”
But is John “free of diabetes”? This is where the lines become blurred. Medically speaking, the term “cure” is usually associated with acute disease—a temporary medical condition, such as bacterial pneumonia, that can be cured with antibiotics. For diabetes, which is a chronic disease, it may be more accurate to use the term “remission” rather than cure. Particularly when considering the pathology associated with diabetes and the individual’s genetic predisposition, relapse is always possible. In a consensus statement issued by the ADA, the term remission is defined based on the following definitions:2
I tried the above hydration / dehydration cycle with my father in June 2014. At that time he was 80 year old. He suffered from Sepsis, Multiple organ failure, Chronic Kidney Disease Stage 5, High Blood Pressure, Severe Constipation, Prostate issues, Epilepsy and Gangrene. The doctors had opined that it is impossible that he can survive even if taken to the best of hospitals in the world.
Other drugs are on the horizon as well, as scientists work to improve the variety of medications to treat type 2 diabetes. Frequently physicians will prescribe one type of oral medication and discover it isn't really helping to control blood glucose that much. In the past, this would have meant that the patient would likely be put on insulin. Now, physicians can try another type of medication to see if it helps correct problems. Physicians often notice that a particular medication works well for a period of time and then begins to work less well for a patient. Now they can mix and match medications that work on different aspects of the diabetes problem to see if that will improve blood glucose control.
Although the promises are big, these technologies are still far from the market. First, clinical trials will have to show they do work. Then, the price could be steep, as cell therapy precedents for other applications, such as oncology, come with price tags that reach the six figures and are finding difficulties to get reimbursed. Considering that compared to cancer, diabetes is not an immediately life-threatening disease, health insurers in some countries might be reluctant to cover the treatment.
