The view that calories are calories regardless of their source has been shown to be outdated. Foods with a low glycemic index are better because they tend to raise blood sugar more slowly, and they are also more likely to be healthier foods overall. By choosing the low-glycemic foods and thus the minimally processed foods, people can lose more weight, feel fuller longer, and remain healthier.
The dangers of sepsis are more pronounced for certain parts of the population, and more likely to be caused by certain types of infections, like pneumonia. It’s vital that patients and those close to them be aware of the signs of sepsis and get immediate medical attention if it is suspected.
Excess sugar in the diet can cause a whole host of health problems, both physical and mental. If you’re concerned about cutting down on sugar, you might think you’re covered if you skip the soda and pastries. But there are plenty of hidden and added sugars lurking in all kinds of foods — even those traditionally considered “healthy.” Here, we’ve given you some tips on what to watch out for.
Doctors are often hesitant to prescribe newer drugs. We simply can’t know everything about them until the experiences of early adopters tell us what they’re really like. Such is the case with thiazolidinediones. Some of the more recent diabetes drugs fell out of favor, but a new study suggests that may be helpful for very specific types of patients.
Diabetes damages every part of the body, from the brain to the feet. High blood sugar, the hallmark of diabetes, wreaks havoc on blood vessels. It makes sense that keeping blood sugar under control should prevent diabetes-related damage — but how low to push blood sugar is an open question. A study published in The New England Journal of Medicine (NEJM) provides reassuring evidence that so-called tight blood sugar control is good for the heart and circulatory system. A 10-year follow-up of the Veterans Affairs Diabetes Trial showed that participants who aimed for tight blood sugar control had lower blood sugar and fewer heart attacks and strokes than participants whose blood sugar was allowed to float a bit higher. Although tight blood sugar control can help prevent diabetes-related damage, it can have drawbacks such as bouts of low blood sugar (hypoglycemia), which can be dangerous. Current guidelines from the American Diabetes Association recommend tight blood sugar control, but also recognize there’s no one-size-fits-all rule.
Ninety years ago, type 1 diabetes was a death sentence: half of people who developed it died within two years; more than 90% were dead within five years. Thanks to the introduction of insulin therapy in 1922, and numerous advances since then, many people with type 1 diabetes now live into their 50s and beyond. But survival in this group still falls short of that among people without diabetes. A Scottish study published this week in JAMA shows that at the age of 20, individuals with type 1 diabetes on average lived 12 fewer years than 20-year-olds without it. A second study in the same issue of JAMA showed that people with type 1 diabetes with better blood sugar control lived longer than those with poorer blood sugar control.
Over the past decade, a barrage of reports linking low vitamin D levels to cancer, heart disease, diabetes, and a host of other ills led many doctors to routinely test vitamin D levels in their healthy patients. But there is no good reason to do that, according to a new recommendation from the U.S. Preventive Services Task Force (USPSTF) published in this week’s Annals of Internal Medicine. The task force concluded that it isn’t helpful for most people to know their vitamin D level, and that even if you have a “low” vitamin D level there’s little evidence that taking a vitamin D supplement will do most people any good.
Researchers at Boston University and Massachusetts General Hospital have developed a bionic pancreas. In an early test of the device, reported online this week in the New England Journal of Medicine, it helped control blood sugar levels in 20 adults and 32 teenagers with type 1 diabetes who went about their daily lives without the constant monitoring and injecting that’s required with type 1 diabetes. Right now, this artificial pancreas is essentially an app that runs on an iPhone wirelessly connected to a monitor worn on the abdomen that continually checks blood sugar and two pumps, one for insulin and one for glucagon. The team that developed the bionic pancreas have begun a second round of testing, and hope to have a more sophisticated version on the market in five years. While not a cure, the development of a bionic pancreas represents a bridge that would let people with type 1 diabetes control their blood sugar with less hassle, and more safely, than they do now.
Two reports released this week shed light on the current state of type 2 diabetes in this country, and their conclusions are promising and sobering. First, the good news: An article in The New England Journal of Medicine shows that rates of diabetes-related problems like heart attack, stroke, and lower-limb amputation are down by more than 50% over the last two decades. Now the bad news: during the same time period, the number of people with diabetes has soared, according to a report in the Annals of Internal Medicine. Today, about 21 million American adults are living with diabetes, and that number is on the upswing. Nearly 70% of Americans are overweight or obese. Unless something is done to reverse this trend, millions more Americans could edge closer to diabetes. Dr. Osama Hamdy, medical director of the Obesity Clinical Program at Harvard-affiliated Joslin Diabetes Center and author of The Diabetes Breakthrough, a newly published book from Harvard Health Publications, offers some strategies for preventing diabetes.
There are many reasons to keep your blood sugar under control: protecting your arteries and nerves are two of them. Here’s another biggie: preventing dementia, the loss of memory and thinking skills that afflicts millions of older Americans. A study published today in the New England Journal of Medicine shows that even in people without diabetes, above normal blood sugar is associated with an increased risk of developing dementia. The study does not prove that high blood sugar causes dementia, only that there is an association between the two. For that reason, don’t start trying to lower your blood sugar simply to preserve your thinking skills, cautions Dr. Nathan. There’s no evidence that strategy will work, although he says it should be studied. But it is still worth keeping an eye on your blood sugar. Excess blood sugar can lead to diabetes and a variety of other health problems, including heart, eye, kidney, and nerve disease.
