In addition to the problems with an increase in insulin resistance, the release of insulin by the pancreas may also be defective and suboptimal. In fact, there is a known steady decline in beta cell production of insulin in type 2 diabetes that contributes to worsening glucose control. (This is a major factor for many patients with type 2 diabetes who ultimately require insulin therapy.) Finally, the liver in these patients continues to produce glucose through a process called gluconeogenesis despite elevated glucose levels. The control of gluconeogenesis becomes compromised.
“Diabetes type 1 is very different from your standard disease. Insulin requirements vary greatly from one day to another and there is no way patients can know what they need,” Roman Hovorka, Professor at the University of Cambridge, explained to me during an interview. His research group is working on the development of an algorithm that can accurately predict insulin requirements for a specific patient at any moment.
Exposure to certain viral infections (mumps and Coxsackie viruses) or other environmental toxins may serve to trigger abnormal antibody responses that cause damage to the pancreas cells where insulin is made. Some of the antibodies seen in type 1 diabetes include anti-islet cell antibodies, anti-insulin antibodies and anti-glutamic decarboxylase antibodies. These antibodies can be detected in the majority of patients, and may help determine which individuals are at risk for developing type 1 diabetes.
One of the biggest hits in type 2 diabetes treatment is glucagon-like peptide (GLP)-1 receptor agonists, which induce insulin production in beta-pancreatic cells while suppressing the secretion of glucagon. All big pharma have GLP-1 drugs on the market or their pipelines, including Sanofi, Eli Lilly, Roche, AstraZeneca and Boehringer Ingelheim. But Novo Nordisk is going a step further with the first oral version of a GLP-1 drug, which is now close to the market.
The review affirmed how effective surgery is at treating diabetes (possibly even type 1 diabetes). Around two-thirds of patients with diabetes experience a full remission soon after surgery, while the rest are often better able to control their blood sugar through diet, exercise and medication. Other studies have shown that diabetics who have surgery outlive those who haven’t. Some longer-term research has suggested that one-third of these successes slide back into having active diabetes after five years, but to a lesser degree than they might have without surgery. By contrast, a 2014 study found that fewer than 2 percent of diabetes patients given standard care experienced any remission within a seven-year span.
"Yes, it's a frustrating case," Darkes told Live Science in an email. "But the doctors have to be as accurate as they can be with what's happened, so they've given a 2-year time scale for completed type 1 reversal." Darkes explained that if he can go without insulin injections for two years, his doctors will be 100 percent sure his diabetes is gone.
What are symptoms of type 2 diabetes in children? Type 2 diabetes is becoming increasingly common in children, and this is linked to a rise in obesity. However, the condition can be difficult to detect in children because it develops gradually. Symptoms, treatment, and prevention of type 2 diabetes are similar in children and adults.
