What happened to trusting medical experts?

In all aspects of our lives, we rely on the knowledge and advice of experts. So why are hundreds of thousands of people in the US rejecting advice on COVID-19 from well-respected health authorities, and embracing advice from those with dubious expertise –– and unproven and potentially dangerous remedies?

Did we really gain weight during the pandemic?

Researchers studying weight gain during the pandemic looked at health records for millions of people from both before it and during the first year of it. Unsurprisingly, a significant percentage of people gained weight, but less expected is that nearly as many people lost weight during the same time period.

Can COVID cause diabetes?

COVID-19 infections may raise the risk of developing diabetes, because the virus can damage insulin-producing cells in the pancreas.

Can I skip vaccination if I had COVID?

Evidence suggests that people who've had COVID-19 may have some natural protection against the virus, but will have a much stronger immune response if they also get the vaccine.

Reduce the health risks from "forever chemicals"

Per- and polyfluoroalkyl substances (PFAS) are a group of thousands of manmade chemicals that are widely used in products such as nonstick pans, stain repellants for furniture and carpets, cosmetics, and industrial products. These compounds are dangerous to human health and may lead to immune system problems and increased risk of certain cancers. Avoiding exposure by filtering water and choosing PFAS-free products can help to reduce those risks.

Can you get shingles more than once?

It is possible to get shingles more than once. But getting vaccinated with the Shingrix vaccine may help prevent this from occurring.

Remember the flu? Yep, it's that time again

Last winter's flu season was mild, partly due to record high rates of flu vaccination and steps people were already taking to protect themselves from COVID-19. But don't let that fool you — some flu seasons are severe, so it it's wise to get a flu shot and take other precautions that can help you stay healthy this winter.

Do people who have COVID-19 go on to develop other diseases?

Evidence suggests that people who recover from COVID-19 have an increased risk for developing new health problems, including heart attacks, high blood pressure, diabetes, high cholesterol, muscle inflammation, blood clots that travel to the lungs, strokes from clots or hemorrhages, or psychosis. This is in addition to permanent damage that can result from having COVID, including damage to the lungs, heart, kidneys, brain, or other organs; and debilitating fatigue, difficulty thinking, and other symptoms that make it hard to function normally at work or at home.

Unvaccinated and misunderstood? Let's talk

As the pandemic drags on, it feels like the US has stalled on vaccinations. COVID hospitalizations and deaths are rising again and people on both sides of the vaccine divide seem frustrated or worse. A recent survey suggests ways to address some obstacles and push for solutions that address a range of concerns.

Does HIPAA prohibit questions about vaccination?

Privacy rules described in the Health Insurance Portability and Accountability Act (HIPAA) prevent disclosure of certain health information to unauthorized people without your permission. Here are the basics on what HIPAA does and doesn't allow –– including whether it's legal to ask and answer questions about COVID-19 vaccination status.
