In a 2025 study, people who followed a Mediterranean diet, reduced their calorie intake, exercised at least 150 minutes a week, and received weight-loss support lowered their diabetes risk and lost more weight than those who only followed a Mediterranean diet.

Science has made astonishing progress in the past 60 years in many areas. Examples include the ability to repair certain defective genes, use stem cells to treat certain diseases, detect and fight many cancers, fight viruses with medications, make organ transplants work, and prevent disease with vaccines and lifestyle changes. Thanks to technological advances, doctors can also see clearly inside the body and use artificial intelligence to speed the development of new medications.

Toasted skin syndrome is a rash that develops in a fishnet-like pattern from direct, chronic, low-level exposure to heat sources such as laptops, electric blankets, heating pads, and heated car seats. The heat dilates superficial blood vessels under the skin, causing the rash.

A 2025 Finnish study found that rosacea often goes undiagnosed in people ages 70 or older. Researchers say this might be due to busy physicians with limited awareness of rosacea or patients' own embarrassment or unwillingness to seek treatment.

Inflammaging is chronic, low-grade inflammation throughout the body that occurs with aging. It is believed to accelerate aging and contribute to more than half of all deaths worldwide by driving various age-related diseases such as arthritis, autoimmune conditions, heart disease, cancer, diabetes, and Alzheimer's disease. People can combat inflammaging through healthy lifestyle measures such as exercising, eating healthfully, controlling weight, managing stress, prioritizing sleep, and limiting alcohol and smoking.

Hyperacusis describes sensitivity to some or all sounds, no matter the volume. Depending on the person, sounds might be uncomfortably loud; cause pain in the ear, head, or another part of the body; trigger negative emotional responses; or make someone dizzy. These reactions might be due to irritated or overactive nerve fibers or muscles in the ear. While doctors have few treatments for hyperacusis, certain strategies help, such as avoiding sound triggers, wearing hearing protection, and engaging in sound therapy.

A 2025 study suggests that respiratory syncytial virus (RSV) can lead to heart-related complications, such as a heart attack, chronic heart failure, or an irregular heartbeat-even in people without a previous heart condition.

Being mindful of how various factors affect blood sugar levels can help people avoid fatigue, curb cravings, boost mood, and manage weight. Blood sugar spikes after people eat carbohydrate-heavy foods, soon dropping again. Eating balanced meals and snacks that include protein, fat, and carbohydrates can maintain more stable blood sugar levels. People can keep blood sugar levels consistent by timing meals, practicing portion control, prioritizing healthy foods, staying active, avoiding smoking, and keeping a food log.

In a 2025 study of nearly a million people with diabetes, those who took GLP-1 drugs had a reduction of 10% to 20% in heart failure, cardiac arrest, lung failure and pneumonia, and dementia, compared with people who took other diabetes medications.
