Levels greater than 13–15 mmol/L (230–270 mg/dL) are considered high, and should be monitored closely to ensure that they reduce rather than continue to remain high. The patient is advised to seek urgent medical attention as soon as possible if blood sugar levels continue to rise after 2–3 tests. High blood sugar levels are known as hyperglycemia, which is not as easy to detect as hypoglycemia and usually happens over a period of days rather than hours or minutes. If left untreated, this can result in diabetic coma and death.

Talking to a counselor or therapist may help you cope with the lifestyle changes that come with a type 2 diabetes diagnosis. You may find encouragement and understanding in a type 2 diabetes support group. Although support groups aren't for everyone, they can be good sources of information. Group members often know about the latest treatments and tend to share their own experiences or helpful information, such as where to find carbohydrate counts for your favorite takeout restaurant. If you're interested, your doctor may be able to recommend a group in your area.

If however, type 2 diabetes is a result of insulin resistance and being overweight, there is excellent evidence that exercise, decreasing added sugars and saturated fats in the diet, choosing low glycaemic index foods and losing weight – particularly around the abdominal region, can improve blood glucose levels to the extent that it seems like diabetes has been reversed.

Alternative medicine for diabetes is big business, because the public health burden of diabetes is massive, and growing. In 1985, the worldwide prevalence was 30 million people. In 2000, it was 150 million. By 2030, it could be 250 million. Why are more people being diagnosed with diabetes? Obesity, sedentary lifestyles, and an aging population. At its core, diabetes is a disease of sugar (glucose) management. Insulin, secreted by the pancreas, allows cells to use glucose. When the pancreas doesn’t produce insulin,  it’s called Type 1 diabetes. This is an autoimmune disease that strikes early in life, and was a death sentence until insulin was discovered.  When the pancreas can produce insulin, but the amount is insufficient, or when there’s a problem with the uptake of insulin into cells, it’s termed type 2 diabetes.  90% of all diabetes is type 2. Typically a disease of older adults, type 2 diabetes can potentially be treated without drugs of any kind, but success rates are low and medication is eventually advisable. There’s also gestational diabetes, a disease of pregnancy, and prediabetes, where blood sugars are elevated, and diabetes is an expected future diagnosis.

Most doctors, dietitians and diabetes specialists claim that type 2 diabetes is a chronic and progressive disease. The American Diabetes Association, for example, almost proudly proclaims this on its website. Once you get the diagnosis, it’s a life sentence. But, it’s actually a great big lie. 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.
Since the body functions as a whole, it is logical that when one hormone or part of the endocrine system is suffering, the other would be affected as well. This is the reason behind the recent research linking high stress levels to diabetes and other health problems. Most people think of stress only in the mental context (as in, “I’ve got a million things to do, I’m running late and I don’t have time to get anything done… I’m so stressed”) but stress can be physical, psychological, emotional, or mental and can be triggered by many factors including:
Gene therapy can be used to manufacture insulin directly: an oral medication, consisting of viral vectors containing the insulin sequence, is digested and delivers its genes to the upper intestines. Those intestinal cells will then behave like any viral infected cell, and will reproduce the insulin protein. The virus can be controlled to infect only the cells which respond to the presence of glucose, such that insulin is produced only in the presence of high glucose levels. Due to the limited numbers of vectors delivered, very few intestinal cells would actually be impacted and would die off naturally in a few days. Therefore, by varying the amount of oral medication used, the amount of insulin created by gene therapy can be increased or decreased as needed. As the insulin-producing intestinal cells die off, they are boosted by additional oral medications.[76]
These are a relatively new class of drugs used to treat type 2 diabetes. They are oral medications that work by blocking the kidneys' reabsorption of glucose, leading to increased glucose excretion and reduction of blood sugar levels. The US FDA approved the SGLT2 inhibitors canagliflozin (Invokana) in March 2013 and dapagliflozin (Farxiga) in January 2014.
