Many Americans may have a potentially serious condition marked by a buildup of fat inside the liver. Known as metabolic dysfunction–associated steatotic liver disease (MASLD), it’s closely linked to a higher risk of cardiovascular disease. The root of the problem is usually excess weight—especially the accumulation of belly fat known as abdominal obesity. Weight gain can trigger a host of metabolic problems that cause blood sugar, blood pressure, and cholesterol levels to rise. All of these factors are closely linked to a higher risk of diabetes and cardiovascular disease. Heart disease is one of the common causes of death among people with MASLD.

Implanted heart devices include pacemakers and implantable cardioverter defibrillators (ICDs), which monitor and correct abnormal heart rhythms. While very reliable, they are not perfect, and recalls of these devices affect thousands of people each year, according to a 2024 study. Testing the effectiveness and safety of cardiac devices is far more complicated than testing drugs. But efforts are under way to improve postmarket tracking of device complications by using electronic health records, Medicare databases, and registries developed in partnership with device manufacturers.

A 2024 study indicates that concentrated, “weekend warrior” exercise is just as effective at protecting against many health conditions as spreading exercise throughout the week.

A 2024 study suggested that closely following the MIND diet, which emphasizes plant-based foods and limited animal products and saturated fats, may slow cognitive decline compared to other eating patterns.

A 2024 study found that older women with urinary incontinence experienced significant improvements in symptoms after engaging in low-impact yoga or stretching and strengthening exercises three times a week for three months.

About three million American adults have epilepsy, which is marked by recurring seizures. But far more people will have a seizure that strikes for another reason. Seizure triggers include high fever, head injury, extreme lack of sleep, blood sugar fluctuations, alcohol or drug misuse, certain medications, brain infections, stroke, and eclampsia. People can help someone having a seizure by moving them away from hazards, preventing choking, and tracking details. Most seizures are not a medical emergency.

Pap tests, the mainstay screening method to detect cervical cancer, are uncomfortable for some women. In mid-2024, the FDA approved a new self-swab test that can detect human papillomavirus, which causes most cases of cervical cancer. The self-swab test collects cells from the vaginal wall instead of the cervix. Clinicians guide women on how to perform the test in a doctor’s office. The self-swab method offers women several benefits, including comfort, accuracy, and potentially greater access to screening.

Cold weather can not only lead to dry skin, but also cause or worsen other skin conditions such as eczema, psoriasis, rosacea, and seborrheic dermatitis. Frosty temperatures and dry air can break down the skin barrier, which contains substances that help seal in moisture. People can ward off or ease winter skin problems by applying creams and ointments, coating cracked skin areas with petroleum jelly, using a humidifier, taking lukewarm showers no more than once a day, and using moisturizing soaps and liquid body cleansers.

A sleep study is performed to detect sleep apnea or other sleep disorders. It often takes place in a special lab. The person is hooked up to equipment that records the brain’s activity and monitors snoring, blood oxygen levels, and other variables.

Ice baths typically happen in water that’s between 50° and 60° F. Studies about their health benefits are inconclusive, but ice baths can be risky. People should never take an ice bath without someone nearby, and stay in for a maximum of 15 minutes.
