Diverticular disease develops due to a lack of dietary fiber, and is most common in the elderly, but many people never realize they have it because there are few symptoms.

Are artificial sweeteners benign or a threat to your long-term health? A recent study adds a new element to the debate.

Artificial sweeteners seem to offer a tantalizing free pass to dessert. These low- or no-calorie additives taste like sugar, but your body can't absorb them the same way it does natural sugars. You get the taste without the calories, which should mean that you can eat them guilt-free. Right?

Over the years, experts have increasingly questioned whether artificial sweeteners are too good to be true. Are they really your ticket to a ­low-calorie treat — or will you wind up getting your just desserts for trying to outsmart Mother Nature?

Ask the doctor

Q. Will we have a vaccine to prevent COVID-19 and, if so, when?

A. I'm optimistic because never in human history has so much scientific time and effort been spent trying to make a vaccine. But it won't it be easy. As fast as possible, the vaccine scientists need to prove, first, that a vaccine is safe (minimal side effects) and, second, that it works to reduce a person's risk of getting the disease. Then they need to produce enough of it to immunize most of the 7.6 billion people on earth. Doing all of this within two to three years of a new virus being discovered would be an unprecedented achievement.

Research we're watching

If you suffer from the common skin condition eczema, you may have a higher risk of breaking a bone compared with someone who doesn't have the condition, according to a study published in the February 2020 issue of The Journal of Allergy and Clinical Immunology. The study authors found that the 500,000 people in the study who had eczema, which causes itchy dry patches on the skin, were 7% to 18% more likely to break a bone in the wrist, hip, pelvis, or spine when compared with more than 2.5 million participants who didn't have the condition. Researchers said it's not clear if this elevated fracture risk was related to the eczema itself or whether other factors caused the association. For example, the increase in risk could have been related to medications people took to treat eczema. Even so, if you have eczema, the study authors say it may be worth asking your doctor whether you might be at increased risk for osteoporosis.

Scientists continue to explore the health benefits versus risks of aspirin therapy. One new analysis suggests that taking aspirin may protect against several types of digestive tract cancers. The results were published online April 1, 2020, by Annals of Oncology.

Researchers examined 113 observational studies of cancer in the general population. They found that individuals who took aspirin regularly — at least one or two tablets a week — had significantly lower rates of cancers of the bowel, stomach, gallbladder, esophagus, pancreas, and liver, compared with people who did not take aspirin.

The latest recommendations focus on newer medications, lifestyle changes, and procedures.

If you have heart disease, following a healthy diet and getting regular exercise should be a top priority. Both habits can help you reach and stay at a healthy weight and lower your blood pressure and cholesterol level. Chances are you'll also need to take medications to further improve those common heart-related risk factors. But if you also have diabetes, you may need even more aggressive treatment, according to new advice from the American Heart Association.

The recommendations, published May 12, 2020, in the journal Circulation, detail the latest evidence about treatments for people with both heart disease and diabetes. Diabetes, which affects about one in 10 adults, doubles the odds of having a heart attack or stroke (see "Why is diabetes hard on your heart?").

Many lifestyle factors can influence the development of atrial fibrillation, and doctors now better understand the importance of these factors in treating afib. Those who are at risk of developing afib can take action to improve their health, and in some cases they may be able to reduce their symptoms.
