Mpox is back: What to know and do

In 2022, the largest known outbreak spread to nearly 100,000 people in more than 100 countries. Now, a new outbreak of mpox has put it back in the news. What should you know - and do - about this latest international health emergency?

Chronic loneliness linked to higher risk of stroke

In a 2024 study by Harvard researchers, people who reported feeling persistently lonely had a 56% higher risk of experiencing a stroke compared with people who did not report feelings of loneliness.

Why does everything taste salty to me?

A variety of factors can make food taste overly salty. These include seasonal or food allergies, medication side effects, gastroesophageal reflux disease (GERD), diabetes, autoimmune conditions, or a chronically dry mouth. People should discuss the problem with their doctor.

The point of knee shots

A growing number of people ages 60 and older suffer from knee osteoarthritis. If lifestyle strategies, such as weight loss, physical therapy, exercise, and oral or topical medications don't offer sufficient pain relief, people may benefit from either corticosteroid or hyaluronic acid injections. Injections can provide immediate pain relief, reduce inflammation, and increase mobility. However, they are a temporary treatment that won't cure knee osteoarthritis or change the course of the disease.

Cooling off heartburn

Heartburn usually goes away on its own, but sometimes medication is needed to provide relief. For occasional heartburn, people can use over-the-counter antacids that are magnesium-based, aluminum-based, or calcium-based. If heartburn strikes several times a week or symptoms become more severe, a nonprescription H2 blocker can help. Individuals with persistent heartburn may have gastroesophageal reflux disease (GERD) and will probably need a proton-pump inhibitor. These are available in over-the-counter and prescription versions.

Are you missing the subtle signs of anemia?

People with anemia have an abnormally low number of red blood cells. Those are the cells that pick up oxygen from the lungs, deliver oxygen throughout the body, and return to the lungs with a load of carbon dioxide and other gases to be exhaled. Without enough red blood cells, the organs and tissues don't get a sufficient amount of oxygen. That can cause nonspecific symptoms, such as fatigue, headache, or wooziness, which are often attributed to other causes. As a result, anemia often goes undiagnosed.

Drinks on a plane: Consider saying no

The combination of drinking alcohol and sleeping while on a plane puts a big strain on the body, especially the cardiovascular system. This is because blood oxygen normally drops slightly when flying high above sea level, sleeping, or consuming alcohol. The more contributors to low blood oxygen there are, the harder the body has to work to compensate by breathing faster and increasing heart rate. There's even more strain if someone has heart or lung disease, which places the person at a higher risk for a heart attack or stroke.

Should you really take that daily aspirin?

A 2024 analysis found that many people without heart problems are taking daily low-dose aspirin therapy, even though it might have more health risks than benefits. Some of them have not consulted with a doctor about whether daily aspirin is safe for them.

Eating a sodium-rich diet is tied to increased eczema risks

A 2024 study of more than 215,000 people (ages 37 to 73) found a link between consuming a sodium-rich diet and increased risks of having eczema, an eczema flare-up, or severe eczema.
