Fiber-rich diets may lower the risk of stroke

People whose average daily diets included at least 18 grams of fiber were less likely to have a stroke than those who ate less fiber, according a 2025 study.

What is essential tremor?

Essential tremor is marked by involuntary shaking of one or more body parts, such as the hands, arms, legs, or head. Avoiding caffeine and stress and getting plenty of rest can be helpful. Several medications are available to ease the symptoms.

Letting the air out of bloating

The digestion process slows as one ages, causing digested food to take its time moving along the gastrointestinal tract from the stomach through the intestines. The longer food stays in the digestive tract, the more opportunity there is for gas to be produced and build up, resulting in bloating. Recurrent bloating also can be caused by people's reactions to certain foods, especially those that contain sugars called FODMAPs. Adjusting one's diet to avoid trigger foods and taking over-the-counter remedies can help prevent and manage problem bloating.

Raising potassium intake might lower high blood pressure

Increasing potassium levels while lowering sodium may be more effective in lowering high blood pressure than reducing dietary salt alone, particularly for men, according to a 2025 study.

Diabetes and obesity drug shows promise for fatty liver disease

Semaglutide, a GLP-1 agonist used to treat diabetes and obesity, may also help people with metabolic dysfunction-associated steatohepatitis, a severe stage of fatty liver disease, suggests a 2025 study.

What's involved with hand therapy

Hand therapy is an effective way to overcome lost hand function due to injuries or underlying conditions. A course of therapy typically lasts for six weeks. It involves working with a certified hand therapist (CHT) who can develop and then guide someone through a tailored program of physical and functional exercises. CHTs also can make splints, offer emotional support, and help people learn to manage hand pain and swelling. It's best to start hand therapy before an injured hand has healed completely.

Brief brain attacks: Short symptoms, long consequences

A 2025 study finds that a first-time transient ischemic attack (TIA) can lead to the same long-term decline in thinking and memory problems as a full-blown stroke. Experts suggest cognitive testing after a TIA. People who have TIAs should take extra care to address risk factors for heart attack and stroke, such as high blood pressure and high cholesterol. Exercising regularly and staying socially active may help ward off cognitive decline.

A new approach to peripheral artery disease

A 2025 randomized controlled trial found that GLP-1 receptor agonists, the blockbuster drugs approved to treat diabetes and obesity, boosted the walking ability of people with diabetes and peripheral artery disease (PAD) in the legs. The news is encouraging, since there are few effective treatments for PAD-reduced blood flow in the limbs that leads to pain with activity. However, it will take more evidence before doctors feel comfortable prescribing GLP-1s if a person only has PAD.

My calcium score is over 2,000. What's next?

People with very high calcium scores (over 1,000) have a risk of heart attack or stroke similar to those who have already had a heart attack. They should take cholesterol-lowering drugs to bring down LDL levels and possibly undergo additional testing.
