The burning of fossil fuels is a major contributor to climate change, and pollution from this burning has been linked to millions of premature deaths worldwide. And, according to a new report, even low levels of air pollution may harm our health although we can take steps to limit exposure.
If you need surgery, does the sex of the surgeon matter? A study reviewed procedures done in Canada over a 12-year period involving more than a million adults, and found that in general, people operated on by female surgeons were less likely to experience complications. But why?
Migraines are a common neurologic condition, but it’s estimated that in the US only about a quarter of adults with migraine are able to get an accurate diagnosis and appropriate treatment. Part of the reason for this is likely due to disparities in health care, and researchers found evidence of disparities related to race, socioeconomic status, insurance coverage, and geography.
Ketamine has been used for decades as an anesthetic, and in 2019 an inhaled version of it was approved by the FDA for treatment-resistant depression. But it is generally prescribed only when other treatments have not been effective.
Recent findings from the largest and longest-running study of risk factors for cardiovascular disease in Black Americans suggest that a positive outlook can lead to longer life. But while optimism may boost heart health and overall health, the full picture is more complicated.
The use of lead in consumer products was banned in the United States in 1978, but lead exposure is still a serious problem today, especially for young children. This led the CDC to lower the blood lead reference value, which is used to identify those at highest risk. When should children be tested for lead exposure, and what should parents do if there is lead in their home?
Have you heard of the blood type diet? I thought it had been debunked long ago but patients keep asking about it, so I figured I should learn more.
Early in the pandemic, the American Academy of Pediatrics recommended that any child who tested positive for COVID-19 have an in-person evaluation with their pediatrician before returning to sports, but recently the AAP updated its guidance with recommendations based on the severity of a child’s illness.
Most of us know a healthy diet reduces the risk of heart disease but may not know it’s possible to choose a combination of foods that help lower risks for many illnesses. An index created by researchers at the Harvard T.H. Chan School of Public Health grades food choices and it’s easy to incorporate components of this into daily eating habits.
Due to the lengthy wait for an appointment with a therapist, many people have turned to the numerous mental health apps available on smartphones. Research did not find convincing evidence that use of any such app resulted in significant improvement in symptoms, but some may be useful as a complement to therapy.
Paths to parenthood vary and people thinking about a pregnancy achieved with donated embryos or with donated eggs or sperm might also be considering adoption. Here are some key questions and issues to consider when thinking about these decisions.
Though decades of research have suggested risk factors for amyotrophic lateral sclerosis, a specific cause remains unknown. New research studied professional football players and found that they had a much higher risk of developing ALS than men in the general population, though the study was only observational.
As the number of people living with dementia continues to increase, the hope that a medication will be able to slow the progression of the disease has not yet been successful. Meanwhile, research has also progressed in nonpharmacological treatments that can help people with memory issues and increase their comfort, potentially helping their families as well.
Most people have heard the nutritional recommendation to eat five servings of fruit per day. But are some fruits better for you than others? Is it okay to eat dried or frozen fruit, or to drink fruit juice? Does it have to be organic?
Currently, the medication abiraterone is approved for treatment of men with prostate cancer that has spread beyond the prostate gland and nearby lymph nodes. But a study found that men who received the drug at earlier stages (before the cancer had spread) in combination with another type of treatment were more likely to live longer than those who received only the control treatment.
Studies of contestants from the TV show The Biggest Loser found that due to changes in metabolism, people who have lost large amounts of weight have to follow an extremely low-calorie diet in order to maintain the weight loss. Subsequent research indicates that these metabolic changes are related to calorie restriction while weight is being lost, but later become a function of sustained physical activity.
A doctor’s serious health threat prompts reflection on the power of spirituality, the value of mindfulness practice, and acknowledgment of mortality as a motivator to reassess one’s priorities.
Ads for consumer health monitoring devices make it seem like having ready and regular access to heart rate, heart rhythm, and electrocardiogram data is something everyone needs. While it may help some people with existing heart conditions, how about for an average person without such a concern?
All parents want their children to be happy and able to successfully navigate life’s challenges. Five core skills form a great foundation, and while parents can and should support young children in building these skills, encouraging teens to reinforce and refine their skills is important.
Plant-based burgers designed to taste like meat are being marketed to vegetarians and meat-eaters alike as nutritious, earth-friendly alternatives to animal protein. How two well-known brands stack up in terms of your health and that of the planet may depend on your priorities.
One trend in the world of fitness is the stretching studio, providing assisted stretching sessions marketed as a way to improve flexibility and ease chronic pain. But those looking to boost their overall health are more likely to benefit from regular, moderate physical activity, and do their stretching at home.
Of the more than six million people over 65 in the US who have Alzheimer’s disease, almost two-thirds are women. This is partly because women live longer than men, but other factors make women more likely to develop the disease, especially later in life.
An adequate supply of primary care physicians is essential for our health care system to function properly, but it’s becoming more and more difficult to find one. Rates of burnout are high among PCPs, and many are considering cutting back their work hours or leaving altogether.
For hundreds of years there have been documented instances of groups of people developing similar, medically inexplicable, and sometimes bizarre symptoms, such as paralysis, involuntary tics, or uncontrollable laughter. Known as sociogenic illness, a recent example appears to be fueled by social media postings—meaning physical proximity is no longer a factor.
