Uncontrolled high blood pressure or diabetes tied to severe COVID-19 outcomes

A 2023 study of 1.5 million people found that those who had uncontrolled high blood pressure or diabetes prior to getting COVID-19 had increased risks for COVID complications (such as hospitalization or being on a ventilator), compared with people whose high blood pressure or diabetes was well controlled.

Will eating red meat bring on diabetes?

In a 2023 Harvard Medical School study of more than 216,000 people (followed for up to 36 years), those who reported eating the most red meat had a 62% higher risk of developing diabetes, compared with those who reported eating the least red meat each week.

Why am I prone to skin tags?

Skin tags are fleshy, soft growths that tend to develop on the neck, under the arms, or around the groin. People who develop many skin tags should see their doctor, since they may be associated with diabetes or metabolic syndrome. Skin tags can be removed using various methods.

Waist-to-hip ratio better than BMI in predicting future health issues

According to a 2023 study, a person's waist-to-hip ratio—the circumference of the waist divided by the circumference of the hip—is a better predictor of future health issues like high blood pressure, heart disease, and type 2 diabetes than body mass index.

How healthy is sugar alcohol?

Food products advertised as being lower in sugar or sugar-free contain sugar substitutes. Sugar alcohol is another ingredient used as a sweetener in food products. But is sugar alcohol a better choice nutritionally than other sweeteners or natural sugar?

Prediabetes linked to higher risk of cardiovascular problems

Even slightly elevated blood sugar levels—a condition known as pre-diabetes—may raise the risk of cardiovascular problems. But attention to weight loss and greater use of medications to lower blood pressure and cholesterol appear to reduce the risk.

Understanding new weight-loss drugs

A newer class of medications used to treat type 2 diabetes called glucagon-like peptide-1 (GLP-1) receptor agonists has gained attention because of their impressive weight-loss results—in many cases, 10% to 20% of a person's body weight. Versions of two of these GLP-1 receptor agonists, liraglutide (Saxenda) and semaglutide (Wegovy), are FDA-approved for weight loss, even for people without diabetes. However, there isn't enough evidence to know whether these drugs might be beneficial or dangerous for people who are not diagnosed with diabetes or obesity.

Are you an everyday exerciser or a weekend warrior?

People who get most of their recommended weekly physical activity over one or two days may lower their heart disease risk just as much as those who are active more regularly throughout the week. Evidence also suggests there's no particular benefit to exercising at certain times of the day, including with respect to mealtimes. So people should be physically active whenever they find it to be most convenient.

A closer look at alcohol's effect on heart health

Excessive drinking can contribute to high blood pressure, obesity, and stroke, while moderate drinking (no more than one drink per day for women and two drinks or fewer per day for men) is linked to a lower risk of heart problems. One possible mechanism might be stress reduction. Brain scans of people who reported light to moderate drinking show less activity in the part of the brain that responds to stress, compared with the scans of people who abstained or drank very little. Stress not only raises blood pressure and heart rate but also triggers inflammation that causes plaque buildup, which contributes to heart attacks.

Testosterone therapy may be safe for men at risk for heart attack and stroke

A 2023 study suggests taking testosterone replacement therapy does not raise the risk for heart attacks or stroke among men with cardiovascular disease or a high risk for it, but it could increase the risk of atrial fibrillation, acute kidney injury, and pulmonary embolism.
