Am I a Good Candidate for an Insulin Pump?
Insulin pumps are primarily used by people with type 1 diabetes, but more type 2 diabetes patients are starting to use the pump. The biggest advantage of the insulin pump is improved blood glucose control. For example, in a four-month study of 79 people with diabetes, pump users had an average HbA1c level that was 0.8 percentage points lower than that of people on injected insulin therapy. In this Health Alert Johns Hopkins experts answer… More...

Stopping Insulin Resistance Before It Leads to Diabetes
Researchers have identified a fat cell protein that may predict insulin resistance and help doctors to prescribe treatments to slow the development of type 2 diabetes.
In a healthy person the pancreas makes enough insulin to keep the supply and use of glucose in balance. In diabetes, the glucose balancing system is disrupted, either because too little insulin is produced or because the body's cells do not respond to insulin normally -- a condition called insulin… More...

Using a Continuous Glucose Monitor
People with diabetes are encouraged to check their blood glucose levels frequently. And now the availability of the continuous glucose monitor (a sensor device) makes testing easier and less painful.
Self-testing of blood glucose with a blood glucose meter is the backbone of diabetes management. Results from the Diabetes Control and Complications Trial (DCCT) indicate that people with diabetes should be more aggressive in their daily monitoring of blood glucose levels if they want to reduce… More...

The Deadly Duet
For every five-point increase in blood pressure, your risk of a heart attack or stroke increases by 20–30%. Add in having diabetes, and that risk is two to four times higher. Diabetes also increases the risk of developing kidney and eye disease. And having high blood pressure makes these two diabetes complications even more likely. So it’s no wonder that some experts refer to diabetes and hypertension as the “deadly duet.” More...

Is Stress Reduction the Missing Step in Your Diabetes Plan?
Controlling stress may help improve your blood glucose control. Biofeedback, yoga, or another stress-reduction technique may help.
If you’re a chronic worrier or blow your cool too easily, take heed: All that fretting and fussing may be bad for your blood glucose levels. Psychological stress as well as anxiety can distract you from following a healthy glucose-control regimen and can produce changes in your body chemistry that make diabetes more difficult to manage. … More...

What Causes Type 1 Diabetes?
Researchers are still trying to identify the risk factors that lead to type 1 diabetes. It’s possible that combined genetic susceptibility and an environmental trigger – perhaps a virus – may cause this serious autoimmune disease.

Research Findings on Diabetes, Alzheimer's Risk, and Vision Problems
Diabetes Update 1 -- High Levels of Insulin May Increase Alzheimer's Risk

Yet Another Good Reason to Eat More High-Fiber Foods
Eating high-fiber foods slows digestion and helps to prevent a rapid rise in blood sugar.
Efforts to prevent type 2 diabetes are especially important for people with known risk factors for developing the disease, such as those with prediabetes, obesity, a family history of diabetes, and a personal history of diabetes during pregnancy (gestational diabetes). The risk of diabetes is also elevated among blacks, Hispanics, Asians, and Native Americans. More...

Closing the Loop on the Insulin Pump
The marriage of the insulin pump and the new continuous glucose sensor could result in a true artificial pancreas in the not-too-distant future.
The insulin pump has been available in the U.S. for people with diabetes since the 1980s. The insulin pump delivers a small amount of insulin into the body throughout the day and also allows you to deliver a larger (bolus) dose before meals. Manufacturers of the insulin pump are introducing new features that could enable insulin pump users to get better results.

Should You Be Taking Byetta?
Byetta (Exenatide), an injected drug for type 2 diabetes, has been approved by the FDA for use in combination with orally administered diabetes drugs. Byetta is prescribed for people who have not achieved optimal glycemic control with metformin, sulfonylurea drugs, or combined metformin-sulfonylurea therapy. In a study of 336 people with inadequately controlled type 2 diabetes, researchers randomly assigned half of the group to self-administered injections of Byetta twice a day at a dose of either 5 or 10 micrograms.

Taking Care of Diabetes Foot Problems
People with diabetes need to pay special attention to their feet for a number of reasons. Diabetes-related nerve damage can reduce feeling in the feet, making it difficult to detect a foot injury. Diabetes can also impair blood circulation and wound healing by narrowing the arteries supplying blood to the legs. A wound on the foot that does not heal can turn into an ulcer (deep sore) that may become infected and possibly even require an amputation if untreated.
