American adults are gaining weight, according to data from the CDC. Twelve U.S. states now have obesity rates of 35% or higher, compared with just six states in 2017 and nine states in 2018. Experts say the trend is particularly concerning because adults with obesity are more prone to severe outcomes from COVID-19.

According to the CDC report, racial and ethnic minority groups are disproportionately affected by obesity. Prevalence rates nationwide were

Early stages of vision-robbing diseases often have no symptoms.

Once you reach age 65, you need comprehensive, dilated eye exams every one or two years — more often if you have eye problems. But doctors say the pandemic is keeping some people from getting eye care.

"Some people are delaying treatment, trying to avoid crowds or health facilities like hospitals. They're not getting their eye pressure checked, and they're not using their eye medications," says Dr. Roberto Pineda, an ophthalmologist and eye surgeon at Harvard-affiliated Massachusetts Eye and Ear.

Try over-the-counter medications, water flossers, and rinses.

Gum pain is hard to ignore. The aching, stinging sensation can linger for days and make eating uncomfortable. If the pain is new, you may worry it signals an undiagnosed condition. As you search for answers, you can relieve pain with a number of home remedies and over-the-counter options.

Sore gum causes

Sore gums have many potential causes. One of the most common is an early (often reversible) stage of gum disease called gingivitis. It happens when buildup of plaque (a sticky film containing bacteria) irritates the gums, making them red, swollen, and prone to bleeding easily.

Bisphenol A (BPA), used to make some plastics and epoxy resins, has made headlines for years because of its association with an increased risk for obesity, diabetes, high blood pressure, and cardiovascular disease in humans. Now high levels of BPA exposure have been linked to an increased risk for premature death from any cause, according to a study published online Aug. 17, 2020, by JAMA Network Open. Scientists analyzed the survival rates of about 3,900 people who provided health information and urine samples and were then followed for 10 years. People with the highest levels of BPA in their urine had a 51% higher risk of dying during that period, primarily from heart disease, compared with people who had the lowest levels of BPA. The findings don't prove that BPA caused premature death, but they add to concerns about BPA's potential toxicity. BPA and related chemicals are found in many products, such as water bottles, cups, dental sealants, paper receipts, and the linings of food and beverage cans and pipes, so it's hard to avoid them. Simple precautions include relying less on canned foods and more on fresh foods; avoiding plastics with a 3 or 7 recycling label; microwaving food in glass or ceramic containers, not plastic; and looking for BPA-free products.

The COVID-19 pandemic has prompted a surge in telemedicine visits. Here's what you need to know about virtual health care.

Telemedicine — interactions with your doctor by video — has been slowly growing for years. But when the COVID-19 pandemic hit the United States earlier this year and forced people into isolation, this emerging form of virtual health care took off.

"In 2020, we've seen a sharp hockey stick–like movement in the number of telemedicine visits," says Dr. Joseph Kvedar, a dermatologist with Harvard-affiliated Massachusetts General Hospital and president of the American Telemedicine Association. "The experience has shown both patients and doctors the many ways telemedicine can improve health care in the current environment and beyond. It appears to be here to stay."

Q. I'm trying to eat less sugar. Can you offer any tips that can help?

A. First, congratulations. Cutting down your consumption of sugar can help protect your health in the long term. Sugar-heavy diets have been linked to health conditions, including obesity, diabetes, and heart disease. Most Americans eat far too much sugar. A U.S. government health and diet survey from 2015–16 found that the average American eats about 17 teaspoons of sugar a day. The Dietary Guidelines for Americans recommend eating no more than the equivalent of 12 teaspoons of sugar a day, and the American Heart Association suggests no more than the equivalent of six teaspoons per day. To cut down on your sugar consumption, your first goal should be to focus on incorporating more whole, unprocessed foods into your daily diet. Eating more of these foods can crowd out processed sources of added sugars in your diet.

Q. My partner says I've been snoring lately. Are there any home remedies I can use to help me stop?

A. Snoring occurs when muscles in your airway relax during sleep, narrowing the airway and making your breath sounds louder as the air forces its way through. There are a number of strategies that can help. Try sleeping on your side instead of your back, which pushes your tongue to the back of your mouth. Clear nasal congestion resulting from allergies or a stuffy nose. Avoid alcohol (which may act as a sedative) and sleep medications known as benzodiazepines, which may cause your airway tissues to relax, making snoring worse. Losing weight can also help, because surplus tissue, caused by weight gain, can put pressure on and compress the airway, making snoring worse. However, if your snoring does not improve, your partner notices that you have periods during the night where your breathing ­appears to stop, or you regularly feel drowsy during the day, it may be time to pay a visit to your doctor. You could have a condition called obstructive sleep apnea, which may require treatment.

Scientists continue to explore the right balance of carbohydrates and fat in people's diets. But for overweight or obese older adults, a recent study found that a low-carbohydrate, high-fat diet might offer special health benefits. The results were published online Aug. 12, 2020, by Nutrition and Metabolism.

Researchers asked 40 obese adults, ages 60 to 75, to follow an eight-week diet in which 10% of calories came from carbs, 25% from protein, and 65% from fat. Carb sources included leafy greens, non-starchy vegetables, some fruit, and high-fiber grains. Protein intake consisted of eggs, fish, pork, and poultry. Fat-containing foods included olive oil, coconut oil, nut oils, nut butter, cheese, coconut milk, and avocados.
